+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# align-text [![NPM version](https://badge.fury.io/js/align-text.svg)](http://badge.fury.io/js/align-text)  [![Build Status](https://travis-ci.org/jonschlinkert/align-text.svg)](https://travis-ci.org/jonschlinkert/align-text)
+
+> Align the text in a string.
+
+**Examples**
+
+Align text values in an array:
+
+```js
+align([1, 2, 3, 100]);
+//=> ['  1', '  2', '  3', '100']
+```
+
+Or [do stuff like this](./example.js):
+
+[![screen shot 2015-06-09 at 2 08 34 am](https://cloud.githubusercontent.com/assets/383994/8051597/7b716fbc-0e4c-11e5-9aef-4493fd22db58.png)](./example.js)
+
+Visit [the example](./example.js) to see how this works.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i align-text --save
+```
+
+## Usage
+
+```js
+var align = require('align-text');
+align(text, callback_function_or_integer);
+```
+
+**Params**
+
+* `text` can be a **string or array**. If a string is passed, a string will be returned. If an array is passed, an array will be returned.
+* `callback|integer`: if an integer, the text will be indented by that amount. If a function, it must return an integer representing the amount of leading indentation to use as `align` loops over each line.
+
+**Example**
+
+```js
+align(text, 4);
+```
+
+Would align:
+
+```
+abc
+abc
+abc
+```
+
+To:
+
+```
+    abc
+    abc
+    abc
+```
+
+## callback
+
+### params
+
+The callback is used to determine the indentation of each line and gets the following params:
+
+* `len` the length of the "current" line
+* `longest` the length of the longest line
+* `line` the current line (string) being aligned
+* `lines` the array of all lines
+
+### return
+
+The callback may return:
+
+* an integer that represents the number of spaces to use for padding,
+* or an object with the following properties:
+  - `indent`: **{Number}** the amount of indentation to use. Default is `0` when an object is returned.
+  - `character`: **{String}** the character to use for indentation. Default is `''` (empty string) when an object is returned.
+  - `prefix`: **{String}** leading characters to use at the beginning of each line. `''` (empty string) when an object is returned.
+
+**Integer example:**
+
+```js
+// calculate half the difference between the length
+// of the current line and the longest line
+function centerAlign(len, longest, line, lines) {
+  return Math.floor((longest - len) / 2);
+}
+```
+
+**Object example:**
+
+```js
+function centerAlign(len, longest, line, lines) {
+  return {
+    character: '\t',
+    indent: Math.floor((longest - len) / 2),
+    prefix: '~ ',
+  }
+}
+```
+
+## Usage examples
+
+### Center align
+
+Using the `centerAlign` function from above:
+
+```js
+align(text, centerAlign);
+```
+
+Would align this text:
+
+```js
+Lorem ipsum dolor sit amet
+consectetur adipiscin
+elit, sed do eiusmod tempor incididun
+ut labore et dolor
+magna aliqua. Ut enim ad mini
+veniam, quis
+```
+
+Resulting in this:
+
+```
+     Lorem ipsum dolor sit amet,
+        consectetur adipiscing
+elit, sed do eiusmod tempor incididunt
+         ut labore et dolore
+    magna aliqua. Ut enim ad minim
+             veniam, quis
+```
+
+**Customize**
+
+If you wanted to add more padding on the left, just pass the number in the callback.
+
+For example, to add 4 spaces before every line:
+
+```js
+function centerAlign(len, longest, line, lines) {
+  return 4 + Math.floor((longest - len) / 2);
+}
+```
+
+Would result in:
+
+```
+         Lorem ipsum dolor sit amet,
+            consectetur adipiscing
+    elit, sed do eiusmod tempor incididunt
+             ut labore et dolore
+        magna aliqua. Ut enim ad minim
+                 veniam, quis
+```
+
+### Bullets
+
+```js
+align(text, function (len, max, line, lines) {
+  return {prefix: ' - '};
+});
+```
+
+Would return:
+
+```
+- Lorem ipsum dolor sit amet,
+- consectetur adipiscing
+- elit, sed do eiusmod tempor incididunt
+- ut labore et dolore
+- magna aliqua. Ut enim ad minim
+- veniam, quis
+```
+
+### Different indent character
+
+```js
+align(text, function (len, max, line, lines) {
+  return { 
+    indent: Math.floor((max - len) / 2), 
+    character: '~', 
+  };
+});
+```
+
+Would return
+
+```
+~~~~~Lorem ipsum dolor sit amet,
+~~~~~~~~consectetur adipiscing
+elit, sed do eiusmod tempor incididunt
+~~~~~~~~~ut labore et dolore
+~~~~magna aliqua. Ut enim ad minim
+~~~~~~~~~~~~~veniam, quis
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# ansi-colors [![NPM version](https://img.shields.io/npm/v/ansi-colors.svg?style=flat)](https://www.npmjs.com/package/ansi-colors) [![NPM downloads](https://img.shields.io/npm/dm/ansi-colors.svg?style=flat)](https://npmjs.org/package/ansi-colors) [![Build Status](https://img.shields.io/travis/doowb/ansi-colors.svg?style=flat)](https://travis-ci.org/doowb/ansi-colors)
+
+Collection of ansi colors and styles.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save ansi-colors
+```
+
+This module was created to make it easy to allow color configuration through options.
+
+If your application will always one or two specific colors, we recommend directly requiring only [the necessary modules](#related-projects).
+
+If your application uses **more than 10 colors**, we recommend using [chalk](https://github.com/chalk/chalk) for faster require times (since chalk loads everything at once). However, when using less than 10 colors this module will be more efficient due to lazy caching the [underlying modules](#related-projects).
+
+## Usage
+
+```js
+var colors = require('ansi-colors');
+```

+
+> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
+
+
+## Install
+
+```
+$ npm install --save ansi-regex
+```
+
+
+## Usage
+
+```js
+const ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001b[4mcake\u001b[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001b[4mcake\u001b[0m'.match(ansiRegex());
+//=> ['\u001b[4m', '\u001b[0m']
+```
+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+![](screenshot.png)
+
+
+## Install
+
+```
+$ npm install --save ansi-styles
+```
+
+
+## Usage
+
+```js
+var ansi = require('ansi-styles');
+
+console.log(ansi.green.open + 'Hello world!' + ansi.green.close);
+```
+
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## Advanced usage
+
+By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `ansi.modifiers`
+- `ansi.colors`
+- `ansi.bgColors`
+
+
+###### Example
+
+```js
+console.log(ansi.colors.green.open);
+```

+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.svg?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+ * - `dest`  Attribute to hold the created object(s)
+ * - `nargs`  The number of command-line arguments that should be consumed.
+ * By default, one argument will be consumed and a single value will be
+ * produced.
+ * - `constant`  Default value for an action with no value.
+ * - `defaultValue`  The value to be produced if the option is not specified.
+ * - `type`  Cast to 'string'|'int'|'float'|'complex'|function (string). If
+ * None, 'string'.
+ * - `choices`  The choices available.
+ * - `required`  True if the action must always be specified at the command
+ * line.
+ * - `help`  The help describing the argument.
+ * - `metavar`  The name to be used for the option's argument with the help
+ * string. If None, the 'dest' value will be used as the name.
+ *
+ * ##### nargs supported values:
+ *
+ * - `N` (an integer) consumes N arguments (and produces a list)
+ * - `?`  consumes zero or one arguments
+ * - `*` consumes zero or more arguments (and produces a list)
+ * - `+` consumes one or more arguments (and produces a list)
+ *
+ * Note: that the difference between the default and nargs=1 is that with the
+ * default, a single value will be produced, while with nargs=1, a list
+ * containing a single value will be produced.

+> Recursively flatten an array or arrays.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save arr-flatten
+```
+
+## Install
+
+Install with [bower](https://bower.io/)
+
+```sh
+$ bower install arr-flatten --save
+```
+
+## Usage
+
+```js
+var flatten = require('arr-flatten');
+
+flatten(['a', ['b', ['c']], 'd', ['e']]);
+//=> ['a', 'b', 'c', 'd', 'e']
+```
+
+## Why another flatten utility?
+
+I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.

+
+> Faster, node.js focused alternative to JavaScript's native array map.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save arr-map
+```
+
+## Why use this?
+
+JavaScript's native `Array.map()` is slow, and other popular array map libraries are focused on browser compatibility, which makes them bloated or less than idea for non-browser usage. This implementation is focused on node.js usage keeping it light and fast.
+
+## Usage
+
+```js
+var map = require('arr-map');
+
+map(['a', 'b', 'c'], function(ele) {
+  return ele + ele;
+});
+//=> ['aa', 'bb', 'cc']
+
+map(['a', 'b', 'c'], function(ele, i) {
+  return i + ele;
+});
+//=> ['0a', '1b', '2c']
+```

+# arr-union [![NPM version](https://img.shields.io/npm/v/arr-union.svg)](https://www.npmjs.com/package/arr-union) [![Build Status](https://img.shields.io/travis/jonschlinkert/arr-union.svg)](https://travis-ci.org/jonschlinkert/arr-union)
+
+> Combines a list of arrays, returning a single array with unique values, using strict equality for comparisons.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i arr-union --save
+```
+
+## Benchmarks
+
+This library is **10-20 times faster** and more performant than [array-union](https://github.com/sindresorhus/array-union).
+
+See the [benchmarks](./benchmark).
+
+```sh
+#1: five-arrays
+  array-union x 511,121 ops/sec ±0.80% (96 runs sampled)
+  arr-union x 5,716,039 ops/sec ±0.86% (93 runs sampled)
+
+#2: ten-arrays
+  array-union x 245,196 ops/sec ±0.69% (94 runs sampled)
+  arr-union x 1,850,786 ops/sec ±0.84% (97 runs sampled)
+
+#3: two-arrays
+  array-union x 563,869 ops/sec ±0.97% (94 runs sampled)
+  arr-union x 9,602,852 ops/sec ±0.87% (92 runs sampled)
+```
+
+## Usage
+
+```js
+var union = require('arr-union');
+
+union(['a'], ['b', 'c'], ['d', 'e', 'f']);
+//=> ['a', 'b', 'c', 'd', 'e', 'f']
+```
+
+Returns only unique elements:
+
+```js
+union(['a', 'a'], ['b', 'c']);
+//=> ['a', 'b', 'c']
+```

+
+> Fast and powerful array sorting. Sort an array of objects by one or more properties. Any number of nested properties or custom comparison functions may be used.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save array-sort
+```
+
+Install with [yarn](https://yarnpkg.com):
+
+```sh
+$ yarn add array-sort
+```
+
+## Usage
+
+Sort an array by the given object property:
+
+```js
+var arraySort = require('array-sort');
+
+arraySort([{foo: 'y'}, {foo: 'z'}, {foo: 'x'}], 'foo');
+//=> [{foo: 'x'}, {foo: 'y'}, {foo: 'z'}]
+```
+
+**Reverse order**
+
+```js
+arraySort([{foo: 'y'}, {foo: 'z'}, {foo: 'x'}], 'foo', {reverse: true});
+//=> [{foo: 'z'}, {foo: 'y'}, {foo: 'x'}]
+```
+
+## Params
+
+```js
+arraySort(array, comparisonArgs);
+```
+
+* `array`: **{Array}** The array to sort
+* `comparisonArgs`: **{Function|String|Array}**: One or more functions or object paths to use for sorting.
+
+## Examples
+
+**[Sort blog posts](examples/blog-posts.js)**
+
+```js
+var arraySort = require('array-sort');
+
+var posts = [
+  { path: 'c.md', locals: { date: '2014-01-09' } },
+  { path: 'a.md', locals: { date: '2014-01-02' } },
+  { path: 'b.md', locals: { date: '2013-05-06' } },
+];
+
+// sort by `locals.date`
+console.log(arraySort(posts, 'locals.date'));
+
+// sort by `path`
+console.log(arraySort(posts, 'path'));
+```
+
+**[Sort by multiple properties](examples/multiple-props.js)**
+
+```js
+var arraySort = require('array-sort');
+
+var posts = [
+  { locals: { foo: 'bbb', date: '2013-05-06' }},
+  { locals: { foo: 'aaa', date: '2012-01-02' }},
+  { locals: { foo: 'ccc', date: '2014-01-02' }},
+  { locals: { foo: 'ccc', date: '2015-01-02' }},
+  { locals: { foo: 'bbb', date: '2014-06-01' }},
+  { locals: { foo: 'aaa', date: '2014-02-02' }},
+];
+
+// sort by `locals.foo`, then `locals.date`
+var result = arraySort(posts, ['locals.foo', 'locals.date']);
+
+console.log(result);
+// [ { locals: { foo: 'aaa', date: '2012-01-02' } },
+//   { locals: { foo: 'aaa', date: '2014-02-02' } },
+//   { locals: { foo: 'bbb', date: '2013-05-06' } },
+//   { locals: { foo: 'bbb', date: '2014-06-01' } },
+//   { locals: { foo: 'ccc', date: '2014-01-02' } },
+//   { locals: { foo: 'ccc', date: '2015-01-02' } } ]
+```
+
+**[Custom function](examples/custom-function.js)**
+
+If custom functions are supplied, array elements are sorted according to the return value of the compare function. See the [docs for ](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort)`Array.sort()` for more details.
+
+```js
+var arr = [
+  {one: 'w', two: 'b'},
+  {one: 'z', two: 'a'},
+  {one: 'x', two: 'c'},
+  {one: 'y', two: 'd'},
+];
+
+function compare(prop) {
+  return function (a, b) {
+    return a[prop].localeCompare(b[prop]);
+  };
+}
+
+var result = arraySort(arr, function (a, b) {
+  return a.two.localeCompare(b.two);
+});
+
+console.log(result);
+// [ { one: 'z', two: 'a' },
+//   { one: 'w', two: 'b' },
+//   { one: 'x', two: 'c' },
+//   { one: 'y', two: 'd' } ]
+```
+
+**[Multiple custom functions](examples/custom-functions.js)**
+
+```js
+var arr = [
+  {foo: 'w', bar: 'y', baz: 'w'},
+  {foo: 'x', bar: 'y', baz: 'w'},
+  {foo: 'x', bar: 'y', baz: 'z'},
+  {foo: 'x', bar: 'x', baz: 'w'},
+];
+
+// reusable compare function
+function compare(prop) {
+  return function (a, b) {
+    return a[prop].localeCompare(b[prop]);
+  };
+}
+
+// the `compare` functions can be a list or array
+var result = arraySort(arr, compare('foo'), compare('bar'), compare('baz'));
+
+console.log(result);
+// [ { foo: 'w', bar: 'y', baz: 'w' },
+//   { foo: 'x', bar: 'x', baz: 'w' },
+//   { foo: 'x', bar: 'y', baz: 'w' },
+//   { foo: 'x', bar: 'y', baz: 'z' } ]
+```

+# arrayify-compact [![NPM version](https://badge.fury.io/js/arrayify-compact.svg)](http://badge.fury.io/js/arrayify-compact)
+
+> Casts the given value to a flatten array, and removes falsey items (similar to lodash compact).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i arrayify-compact --save
+```
+
+Install with [bower](http://bower.io/)
+
+```sh
+$ bower install arrayify-compact --save
+```
+
+## Usage
+
+```js
+var arrayify = require('arrayify-compact');
+arrayify('a');
+//=> ['a']
+
+arrayify(['a', 'b', ['c', ['d']]]);
+//=> ['a', 'b', 'c', 'd']
+
+arrayify(['a', 'b', ['c', ['d'], null, false, 0, NaN, '', [], undefined]]);
+//=> ['a', 'b', 'c', 'd']
+```

+### v0.24.0
+
+- Bumps [templates][] to v0.24.0 to use the latest [base-data][] which removed the `renameKey` option from the `.data` method. Use the `namespace` option instead.
+
+### v0.23.0
+
+- Bumps [templates][] to v0.23.0 to fix bug with double rendering in [engine-cache][].
+
+### v0.22.0
+
+Bumps [templates][] to v0.22.0 to take advantage of fixes and improvements to lookup methods: `.find` and `getView`. No API changes were made. Please [let us know](../../issues) if regressions occur.
+
+- fixes `List` bug that was caused collection helpers to explode
+- Improvements to lookup functions: `app.getView()` and `app.find()`
+- Bumps [base][] to take advantages of code optimizations.
+
+### v0.21.0
+
+- Bumps [templates][] to v0.21.0. Support for the `queue` property was removed on collections. See [templates][] for additional details.
+
+### v0.20.0
+
+- Bumps [templates][] to v0.20.0. Some changes were made to context handling that effected one unit test out of ~1,000. although it's unlikely you'll be effected by the change, it warrants a minor bump
+
+### v0.19.0
+
+- Bumps [templates][] to v0.19.0
+- Externalizes tests (temporarily) to base-test-runner, until we get all of the tests streamlined to the same format.
+
+### v0.18.0
+
+- Bumps [assemble-loader][] to v0.5.0, which includes which fixes a bug where `renameKey` was not always being used when defined on collection loader options.
+- Bumps [templates][] to v0.18.0, which includes fixes for resolving layouts
+
+### v0.17.0
+
+- Bumps [templates][] to v0.17.0
+
+### v0.16.0
+
+- Bumps [assemble-render-file][] to v0.5.0 and [templates][] to v0.16.0
+
+### v0.15.0
+
+- Bumps [assemble-streams][] to v0.5.0
+
+### v0.14.0
+
+- Bumps [templates][] to v0.15.1
+- adds logging methods from [base-logger][] (`.log`, `.verbose`, etc)
+- `.handleView` method is now deprecated, use `.handleOnce` instead
+- Private method `.mergePartialsSync` rename was reverted to `.mergePartials` to be consistent with other updates in `.render` and `.compile`. No other breaking changes, but some new features were added to [templates][] for handling context in views and helpers.
+
+### v0.13.0
+
+- Breaking change: bumps [templates][] to v0.13.0 to fix obscure rendering bug when multiple duplicate partials were rendered in the same view. But the fix required changing the `.mergePartials` method to be async. If you're currently using `.mergePartials`, you can continue to do so synchronously using the `.mergePartialsSync` method.
+
+### v0.9.0
+
+- Updates [composer][] to v0.11.0, which removes the `.watch` method in favor of using the [base-watch][] plugin.
+
+### v0.8.0
+
+- Bumps several deps. [templates][] was bumped to 0.9.0 to take advantage of event handling improvements.
+
+### v0.7.0
+
+- Bumps [templates][] to 0.8.0 to take advantage of `isType` method for checking a collection type, and a number of improvements to how collections and views are instantiated and named.
+
+### v0.6.0
+
+- Bumps [assemble-fs][] plugin to 0.5.0, which introduces `onStream` and `preWrite` middleware handlers.
+- Bumps [templates][] to 0.7.0, which fixes how non-cached collections are initialized. This was done as a minor instead of a patch since - although it's a fix - it could theoretically break someone's setup.
+
+### v0.5.0
+
+- Bumps [templates][] to latest, 0.6.0, since it uses the latest [base-methods][], which introduces prototype mixins. No API changes.
+
+### v0.4.0
+
+- Removed [emitter-only][] since it was only includes to be used in the default listeners that were removed in an earlier release. In rare cases this might be a breaking change, but not likely.
+- Adds lazy-cache
+- Updates [assemble-streams][] plugin to latest

+
+> Assemble pipeline plugin for handling custom middleware stages.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save assemble-handle
+```
+
+## Usage
+
+```js
+var handle = require('assemble-handle');
+```
+
+### handle
+
+Handle middleware for the given middleware "stage".
+
+```js
+app.task('default', function() {
+  return app.src('*.js')
+    .pipe(handle(app, 'handlerName')) //<= handle middleware
+    .pipe(app.dest('foo'))
+});
+```
+
+**Example**
+
+```js
+var assemble = require('assemble');
+var handle = require('assemble-handle');
+var app = assemble();
+
+/**
+ * create some middleware "stages"
+ */
+
+app.handler('onStream');
+app.handler('preWrite');
+app.handler('postWrite');
+
+/**
+ * Create middleware
+ */
+
+app.onStream(/\.(js|css)$/, function(file, next) {
+  // lint javascript
+  next();
+});
+
+app.preWrite(/\.(jpg|png)$/, function(file, next) {
+  // minify images
+  next();
+});
+
+app.postWrite(/./, function(file, next) {
+  // create files tree or something
+  next();
+});
+
+/**
+ * Run (handle) the middleware 
+ */
+
+app.task('site', function() {
+  return app.src('assets/**/*.*')
+    .pipe(handle(app, 'onStream'))  // handle onStream
+    .pipe(handle(app, 'preWrite'))  // handle preWrite
+    .pipe(app.dest('site/'));
+    .pipe(handle(app, 'postWrite')) // handle postWrite
+});
+```
+
+### handle.once
+
+A `.once` method is exposed, which has the same exact behavior as the main function, but will ensure that middleware is only handled once for a given "stage".
+
+**Example**
+
+For example the given middleware will only run once.
+
+```js
+var assemble = require('assemble-core');
+var handle = require('assemble-handle');
+var app = assemble();
+
+app.handler('onFoo');
+
+app.onFoo(/./, function(file, next) {
+  file.count = file.count || 0;
+  file.count++;
+  next();
+});
+
+app.task('handle-once', function(cb) {
+  var files = [];
+  app.src('test/**/*.*')
+    .pipe(handle.once(app, 'onFoo'))
+    .pipe(handle.once(app, 'onFoo'))
+    .pipe(handle.once(app, 'onFoo'))
+    .pipe(handle.once(app, 'onFoo'))
+    .pipe(handle.once(app, 'onFoo'))
+    .on('data', function(file) {
+      files.push(file);
+    })
+    .pipe(app.dest('test/actual'))
+    .on('end', function() {
+      console.log(files[0].count);
+      //=> 1
+      cb();
+    });
+});
+
+app.task('handle', function(cb) {
+  var files = [];
+  app.src('test/**/*.*')
+    .pipe(handle(app, 'onFoo'))
+    .pipe(handle(app, 'onFoo'))
+    .pipe(handle(app, 'onFoo'))
+    .pipe(handle(app, 'onFoo'))
+    .pipe(handle(app, 'onFoo'))
+    .on('data', function(file) {
+      files.push(file);
+    })
+    .pipe(app.dest('test/actual'))
+    .on('end', function() {
+      console.log(files[0].count);
+      //=> 5
+      cb();
+    });
+});
+```
+
+## Custom handlers
+
+Create custom middleware handlers.
+
+```js
+app.handler('onFoo');
+```
+
+This adds an `.onFoo` method to the instance:
+
+```js
+app.onFoo(/\.hbs$/, function(file, next) {
+  // do stuff to file
+  next();
+});
+```
+
+All `.onFoo` middleware will now run when the `onFoo` handler is called:
+
+```js
+app.task('default', function() {
+  return app.src('*.hbs')
+
+    // call the `onFoo` handler
+    .pipe(handle(app, 'onFoo')) 
+});
+```

+# is-valid-instance [![NPM version](https://img.shields.io/npm/v/is-valid-instance.svg?style=flat)](https://www.npmjs.com/package/is-valid-instance) [![NPM downloads](https://img.shields.io/npm/dm/is-valid-instance.svg?style=flat)](https://npmjs.org/package/is-valid-instance) [![Build Status](https://img.shields.io/travis/jonschlinkert/is-valid-instance.svg?style=flat)](https://travis-ci.org/jonschlinkert/is-valid-instance)
+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+Assemble plugin for rendering views in a vinyl pipeline.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save assemble-render-file
+```
+
+## Usage
+
+```js
+var renderFile = require('assemble-render-file');
+var assemble = require('assemble');
+
+// register as an instance plugin with assemble
+var app = assemble()
+  .use(renderFile());
+
+// then use in a vinyl pipeline
+app.src('*.hbs')
+  .pipe(app.renderfile())
+  .pipe(app.dest('foo'));
+```
+
+### noop engine
+
+By default, when no engine is found for a file an error is thrown. To get around this you can either define a `noop` engine, or use disable the [engineStrict option](#optionsengineStrict).
+
+A noop engine follows the same signature as any engine, but must be registered using the key: `noop`.
+
+**Example**
+
+```js
+app.engine('noop', function(view, opts, next) {
+  // do whatever you want to `view`, or nothing
+  next(null, view);
+});
+```
+
+## Options
+
+### options.engineStrict
+
+By default, when no engine is found for a file an error is thrown. This can be disabled with the following:
+
+```js
+app.option('engineStrict', false);
+```
+
+When disabled and an engine is not found, files are just passed through.

+
+Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+// register the plugin
+app.use(stream());
+
+// use the plugin on app
+app.toStream('pages')
+  .pipe(app.dest('site/'));
+
+// use the plugin on a collection
+app.pages.toStream()
+  .pipe(app.dest('site/'));
+
+// use the plugin on a view
+app.pages.getView('home').toStream()
+  .pipe(app.dest('site/'));
+```
+
+See the [tests](./test.js) for more examples.
+

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+# assign-symbols [![NPM version](https://badge.fury.io/js/assign-symbols.svg)](http://badge.fury.io/js/assign-symbols)
+
+> Assign the enumerable es6 Symbol properties from an object (or objects) to the first object passed on the arguments. Can be used as a supplement to other extend, assign or merge methods as a polyfill for the Symbols part of the es6 Object.assign method.
+
+From the [Mozilla Developer docs for Symbol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol):
+
+> A symbol is a unique and immutable data type and may be used as an identifier for object properties. The symbol object is an implicit object wrapper for the symbol primitive data type.

+## Install
+
+Install with [npm](https://www.npmjs.com/)

+
+## Usage
+
+```js
+var assignSymbols = require('assign-symbols');

+# assign-symbols [![NPM version](https://badge.fury.io/js/assign-symbols.svg)](http://badge.fury.io/js/assign-symbols)
+
+> Assign the enumerable es6 Symbol properties from an object (or objects) to the first object passed on the arguments. Can be used as a supplement to other extend, assign or merge methods as a polyfill for the Symbols part of the es6 Object.assign method.
+
+From the [Mozilla Developer docs for Symbol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol):
+
+> A symbol is a unique and immutable data type and may be used as an identifier for object properties. The symbol object is an implicit object wrapper for the symbol primitive data type.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i assign-symbols --save
+```
+
+## Usage
+
+```js
+var assignSymbols = require('assign-symbols');
+var obj = {};
+
+var one = {};
+var symbolOne = Symbol('aaa');
+one[symbolOne] = 'bbb';
+
+var two = {};
+var symbolTwo = Symbol('ccc');
+two[symbolTwo] = 'ddd';
+
+assignSymbols(obj, one, two);
+
+console.log(obj[symbolOne]);
+//=> 'bbb'
+console.log(obj[symbolTwo]);
+//=> 'ddd'
+```

+
+Allows libraries to handle various caller provided asynchronous functions uniformly. Maps promises, observables, child processes and streams, and callbacks to callback style.
+
+As async conventions evolve, it is useful to be able to deal with several different *styles* of async completion uniformly. With this module you can handle completion using a node-style callback, regardless of a return value that's a promise, observable, child process or stream.
+
+## Usage
+
+### Successful completion
+
+```js
+var asyncDone = require('async-done');
+
+asyncDone(function(done){
+  // do async things
+  done(null, 2);
+}, function(error, result){
+  // `error` will be null on successful execution of the first function.
+  // `result` will be the result from the first function.
+});
+```
+
+### Failed completion
+
+```js
+var asyncDone = require('async-done');
+
+asyncDone(function(done){
+  // do async things
+  done(new Error('Some Error Occurred'));
+}, function(error, result){
+  // `error` will be an error from the first function.
+  // `result` will be undefined on failed execution of the first function.
+});
+```
+
+## API
+
+### `asyncDone(fn, callback)`
+
+Takes a function to execute (`fn`) and a function to call on completion (`callback`).
+
+#### `fn([done])`
+
+Optionally takes a callback to call when async tasks are complete.
+
+#### Completion and Error Resolution
+
+* `Callback` (`done`) called
+  - Completion: called with null error
+  - Error: called with non-null error
+* `Stream` or `EventEmitter` returned
+  - Completion: [end-of-stream][end-of-stream] module
+  - Error: [domains][domains]
+  - __Note:__ Only actual streams are supported, not faux-streams; Therefore, modules like [`event-stream`][event-stream] are not supported.
+* `Child Process` returned
+  - Completion [end-of-stream][end-of-stream] module
+  - Error: [domains][domains]
+* `Promise` returned
+  - Completion: [onFulfilled][promise-onfulfilled] method called
+  - Error: [onRejected][promise-onrejected] method called
+* `Observable` (e.g. from [RxJS v5][rxjs5-observable] or [RxJS v4][rxjs5-observable]) returned
+  - Completion: [complete][rxjs5-observer-complete] method called
+  - Error: [error][rxjs5-observer-error] method called
+
+__Warning:__ Sync tasks are __not supported__ and your function will never complete if the one of the above strategies is not used to signal completion. However, thrown errors will be caught by the domain.
+
+#### `callback(error, result)`
+
+If an error doesn't occur in the execution of the `fn` function, the `callback` method will receive the results as its second argument. Note: Some streams don't received any results.
+
+If an error occurred in the execution of the `fn` function, The `callback` method will receive an error as its first argument.
+
+Errors can be caused by:
+
+* A thrown error
+* An error passed to a `done` callback
+* An `error` event emitted on a returned `Stream`, `EventEmitter` or `Child Process`
+* A rejection of a returned `Promise` - If the `Promise` is not rejected with a value, we generate a new `Error`
+* The `onError` handler being called on an `Observable`

+/**
+ * Notes about these type definitions:
+ *
+ * - Callbacks returning multiple completion values using multiple arguments are not supported by these types.
+ *   Prefer to use Node's style by grouping your values in a single object or array.
+ *   Support for this kind of callback is blocked by Microsoft/TypeScript#5453
+ *
+ * - For ease of use, `asyncDone` lets you pass callback functions with a result type `T` instead of `T | undefined`.
+ *   This matches Node's types but can lead to unsound code being typechecked.
+ *
+ *   The following code typechecks but fails at runtime:
+ *   ```typescript
+ *   async function getString(): Promise<string> {
+ *     return "Hello, World!";
+ *   }
+ *
+ *   async function evilGetString(): Promise<string> {
+ *     throw new Error("Hello, World!");
+ *   }
+ *
+ *   function cb(err: Error | null, result: string): void {
+ *     // This is unsound because `result` is `undefined` when `err` is not `null`.
+ *     console.log(result.toLowerCase());
+ *   }
+ *
+ *   asyncDone(getString, cb); // Prints `hello, world!`
+ *   asyncDone(evilGetString, cb); // Runtime error: `TypeError: Cannot read property 'toLowerCase' of undefined`
+ *   ```
+ *
+ *   Enforcing stricter callbacks would require developers to use `result?: string` and assert the existence
+ *   of the result either by checking it directly or using the `!` assertion operator after testing for errors.
+ *   ```typescript
+ *   function stricterCb1(err: Error | null, result?: string): void {
+ *     if (err !== null) {
+ *       console.error(err);
+ *       return;
+ *     }
+ *     console.log(result!.toLowerCase());
+ *   }
+ *
+ *   function stricterCb2(err: Error | null, result?: string): void {
+ *     if (result === undefined) {
+ *       console.error("Undefined result. Error:);
+ *       console.error(err);
+ *       return;
+ *     }
+ *     console.log(result.toLowerCase());

+# async-each
+
+No-bullshit, ultra-simple, 35-lines-of-code async parallel forEach function for JavaScript.
+
+We don't need junky 30K async libs. Really.
+
+For browsers and node.js.
+
+## Installation
+* Just include async-each before your scripts.
+* `npm install async-each` if you’re using node.js.
+
+## Usage
+
+* `each(array, iterator, callback);` — `Array`, `Function`, `(optional) Function`
+* `iterator(item, next)` receives current item and a callback that will mark the item as done. `next` callback receives optional `error, transformedItem` arguments.
+* `callback(error, transformedArray)` optionally receives first error and transformed result `Array`.
+
+```javascript
+var each = require('async-each');
+each(['a.js', 'b.js', 'c.js'], fs.readFile, function(error, contents) {
+  if (error) console.error(error);
+  console.log('Contents for a, b and c:', contents);
+});
+
+// Alternatively in browser:
+asyncEach(list, fn, callback);
+```

+Resolve a stashed helper by the generated id. This is a generator function and should be used with [co](https://github.com/tj/co)
+
+**Params**
+
+* `key` **{String}**: ID generated when from executing a wrapped helper.
+
+**Example**
+

+  .catch(console.error);
+
+//=> DOOWB
+```
+
+### [.resolveIds](index.js#L423)
+
+After rendering a string using wrapped async helpers, use `resolveIds` to invoke the original async helpers and replace the async ids with results from the async helpers.
+
+**Params**
+
+* `str` **{String}**: String containing async ids
+* `cb` **{Function}**: Callback function accepting an `err` and `content` parameters.
+
+**Example**

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+async-settle
+============
+
+[![build status](https://secure.travis-ci.org/phated/async-settle.png)](http://travis-ci.org/phated/async-settle)
+
+Settle your async functions - when you need to know all your parallel functions are complete (success or failure)
+
+## API
+
+### `settle(executor, onComplete)` : Function
+
+Takes a function to execute (`executor`) and a function to call on completion (`onComplete`).
+
+`executer` is executed in the context of [`async-done`](https://github.com/phated/async-done), with all errors and results being settled.
+
+`onComplete` will be called with a settled value.
+
+#### Settled Values
+
+Settled values have two properties, `state` and `value`.
+
+`state` has two possible options `'error'` and `'success'`.
+
+`value` will be the value passed to original callback.

+async-done
+==========
+
+[![build status](https://secure.travis-ci.org/phated/async-done.png)](http://travis-ci.org/phated/async-done)
+
+Handles completion and errors for callbacks, promises, observables and streams.
+
+Will run call the function on `nextTick`. This will cause all functions to be async.
+
+## Usage
+
+### Successful completion
+
+```js
+var asyncDone = require('async-done');
+
+asyncDone(function(done){
+  // do async things
+  done(null, 2);
+}, function(error, result){
+  // `error` will be undefined on successful execution of the first function.
+  // `result` will be the result from the first function.
+});
+```
+
+### Failed completion
+
+```js
+var asyncDone = require('async-done');
+
+asyncDone(function(done){
+  // do async things
+  done(new Error('Some Error Occurred'));
+}, function(error, result){
+  // `error` will be an error from the first function.
+  // `result` will be undefined on failed execution of the first function.
+});
+```
+
+## API
+
+### `asyncDone(fn, callback)`
+
+Takes a function to execute (`fn`) and a function to call on completion (`callback`).
+
+#### `fn([done])`
+
+Optionally takes a callback to call when async tasks are complete.
+
+#### Completion and Error Resolution
+
+* `Callback` called
+  - Completion: called with null error
+  - Error: called with non-null error
+* `Stream` or `EventEmitter` returned
+  - Completion: [end-of-stream](https://www.npmjs.org/package/end-of-stream) module
+  - Error: [domains](http://nodejs.org/api/domain.html)
+* `Promise` returned
+  - Completion: [onFulfilled](http://promisesaplus.com/#point-26) method called
+  - Error: [onRejected](http://promisesaplus.com/#point-30) method called
+* `Observable` returned
+  - Completion: [onCompleted](https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/observable.md#rxobservableprototypesubscribeobserver--onnext-onerror-oncompleted) method called
+  - Error: [onError](https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/observable.md#rxobservableprototypesubscribeobserver--onnext-onerror-oncompleted) method called
+
+__Warning:__ Sync taks are __not supported__ and your function will never complete if the one of the above strategies is not used to signal completion. However, thrown errors will be caught by the domain.
+
+#### `callback(error, result)`
+
+If an error doesn't occur in the execution of the `fn` function, the `callback` method will receive the results as its second argument. Note: Observable and some streams don't received any results.
+
+If an error occurred in the execution of the `fn` function, The `callback` method will receive an error as its first argument.
+
+Errors can be caused by:
+
+* A thrown error
+* An error passed to a `done` callback
+* An `error` event emitted on a returned `Stream` or `EventEmitter`
+* A rejection of a returned `Promise`
+* The `onError` handler being called on an `Observable`

+# end-of-stream
+
+A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
+
+	npm install end-of-stream
+
+## Usage
+
+Simply pass a stream and a callback to the `eos`.
+Both legacy streams and streams2 are supported.
+
+``` js
+var eos = require('end-of-stream');
+
+eos(readableStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended');
+});
+
+eos(writableStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has finished');
+});
+
+eos(duplexStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended and finished');
+});
+
+eos(duplexStream, {readable:false}, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended but might still be writable');
+});
+
+eos(duplexStream, {writable:false}, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended but might still be readable');
+});
+
+eos(readableStream, {error:false}, function(err) {
+	// do not treat emit('error', err) as a end-of-stream
+});
+```

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```

+
+
+Async is a utility module which provides straight-forward, powerful functions
+for working with asynchronous JavaScript. Although originally designed for
+use with [Node.js](http://nodejs.org) and installable via `npm install async`,
+it can also be used directly in the browser.
+
+Async is also installable via:
+
+- [bower](http://bower.io/): `bower install async`
+- [component](https://github.com/component/component): `component install
+  caolan/async`
+- [jam](http://jamjs.org/): `jam install async`
+- [spm](http://spmjs.io/): `spm install async`
+
+Async provides around 20 functions that include the usual 'functional'
+suspects (`map`, `reduce`, `filter`, `each`…) as well as some common patterns
+for asynchronous control flow (`parallel`, `series`, `waterfall`…). All these
+functions assume you follow the Node.js convention of providing a single
+callback as the last argument of your `async` function.
+
+
+## Quick Examples
+
+```javascript
+async.map(['file1','file2','file3'], fs.stat, function(err, results){
+    // results is now an array of stats for each file
+});
+
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+
+async.parallel([
+    function(){ ... },
+    function(){ ... }
+], callback);
+
+async.series([
+    function(){ ... },
+    function(){ ... }
+]);
+```
+
+There are many more functions available so take a look at the docs below for a
+full list. This module aims to be comprehensive, so if you feel anything is
+missing please create a GitHub issue for it.
+
+## Common Pitfalls <sub>[(StackOverflow)](http://stackoverflow.com/questions/tagged/async.js)</sub>
+### Synchronous iteration functions
+
+If you get an error like `RangeError: Maximum call stack size exceeded.` or other stack overflow issues when using async, you are likely using a synchronous iterator.  By *synchronous* we mean a function that calls its callback on the same tick in the javascript event loop, without doing any I/O or using any timers.  Calling many callbacks iteratively will quickly overflow the stack. If you run into this issue, just defer your callback with `async.setImmediate` to start a new call stack on the next tick of the event loop.
+
+This can also arise by accident if you callback early in certain cases:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    callback(null, cache[item]); // if many items are cached, you'll overflow
+  } else {
+    doSomeIO(item, callback);
+  }
+}, function done() {
+  //...
+});
+```
+
+Just change it to:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    async.setImmediate(function () {
+      callback(null, cache[item]);
+    });
+  } else {
+    doSomeIO(item, callback);
+  //...
+```
+
+Async guards against synchronous functions in some, but not all, cases.  If you are still running into stack overflows, you can defer as suggested above, or wrap functions with [`async.ensureAsync`](#ensureAsync)  Functions that are asynchronous by their nature do not have this problem and don't need the extra callback deferral.
+
+If JavaScript's event loop is still a bit nebulous, check out [this article](http://blog.carbonfive.com/2013/10/27/the-javascript-event-loop-explained/) or [this talk](http://2014.jsconf.eu/speakers/philip-roberts-what-the-heck-is-the-event-loop-anyway.html) for more detailed information about how it works.
+
+
+### Multiple callbacks
+
+Make sure to always `return` when calling a callback early, otherwise you will cause multiple callbacks and unpredictable behavior in many cases.
+
+```js
+async.waterfall([
+    function (callback) {
+        getSomething(options, function (err, result) {
+          if (err) {
+            callback(new Error("failed getting something:" + err.message));
+            // we should return here
+          }
+          // since we did not return, this callback still will be called and
+          // `processData` will be called twice
+          callback(null, result);
+        });
+    },
+    processData
+], done)
+```
+
+It is always good practice to `return callback(err, result)`  whenever a callback call is not the last statement of a function.
+
+
+### Binding a context to an iterator
+
+This section is really about `bind`, not about `async`. If you are wondering how to
+make `async` execute your iterators in a given context, or are confused as to why
+a method of another library isn't working as an iterator, study this example:
+
+```js
+// Here is a simple object with an (unnecessarily roundabout) squaring method
+var AsyncSquaringLibrary = {
+  squareExponent: 2,
+  square: function(number, callback){
+    var result = Math.pow(number, this.squareExponent);
+    setTimeout(function(){
+      callback(null, result);
+    }, 200);
+  }
+};
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){
+  // result is [NaN, NaN, NaN]
+  // This fails because the `this.squareExponent` expression in the square
+  // function is not evaluated in the context of AsyncSquaringLibrary, and is
+  // therefore undefined.
+});
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){
+  // result is [1, 4, 9]
+  // With the help of bind we can attach a context to the iterator before
+  // passing it to async. Now the square function will be executed in its
+  // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent`
+  // will be as expected.
+});
+```

+## Collections
+
+<a name="forEach" />
+<a name="each" />
+### each(arr, iterator, [callback])
+
+Applies the function `iterator` to each item in `arr`, in parallel.
+The `iterator` is called with an item from the list, and a callback for when it
+has finished. If the `iterator` passes an error to its `callback`, the main
+`callback` (for the `each` function) is immediately called with the error.
+
+Note, that since this function applies `iterator` to each item in parallel,
+there is no guarantee that the iterator functions will complete in order.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err)` which must be called once it has
+  completed. If no error has occurred, the `callback` should be run without
+  arguments or with an explicit `null` argument.  The array index is not passed
+  to the iterator.  If you need the index, use [`forEachOf`](#forEachOf).
+* `callback(err)` - *Optional* A callback which is called when all `iterator` functions
+  have finished, or an error occurs.
+
+__Examples__
+
+
+```js
+// assuming openFiles is an array of file names and saveFile is a function
+// to save the modified contents of that file:
+
+async.each(openFiles, saveFile, function(err){
+    // if any of the saves produced an error, err would equal that error
+});
+```
+
+```js
+// assuming openFiles is an array of file names
+
+async.each(openFiles, function(file, callback) {
+
+  // Perform operation on file here.
+  console.log('Processing file ' + file);
+
+  if( file.length > 32 ) {
+    console.log('This file name is too long');
+    callback('File name too long');
+  } else {
+    // Do work to process file here
+    console.log('File processed');
+    callback();
+  }
+}, function(err){
+    // if any of the file processing produced an error, err would equal that error
+    if( err ) {
+      // One of the iterations produced an error.
+      // All processing will now stop.
+      console.log('A file failed to process');
+    } else {
+      console.log('All files have been processed successfully');
+    }
+});

+
+### forEachOf(obj, iterator, [callback])
+
+Like `each`, except that it iterates over objects, and passes the key as the second argument to the iterator.
+
+__Arguments__
+
+* `obj` - An object or array to iterate over.
+* `iterator(item, key, callback)` - A function to apply to each item in `obj`.
+The `key` is the item's key, or index in the case of an array. The iterator is
+passed a `callback(err)` which must be called once it has completed. If no
+error has occurred, the callback should be run without arguments or with an
+explicit `null` argument.
+* `callback(err)` - *Optional* A callback which is called when all `iterator` functions have finished, or an error occurs.
+
+__Example__
+
+```js
+var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
+var configs = {};
+
+async.forEachOf(obj, function (value, key, callback) {
+  fs.readFile(__dirname + value, "utf8", function (err, data) {
+    if (err) return callback(err);
+    try {
+      configs[key] = JSON.parse(data);
+    } catch (e) {
+      return callback(e);
+    }
+    callback();
+  })
+}, function (err) {

+
+<a name="map" />
+### map(arr, iterator, [callback])
+
+Produces a new array of values by mapping each value in `arr` through
+the `iterator` function. The `iterator` is called with an item from `arr` and a
+callback for when it has finished processing. Each of these callback takes 2 arguments:
+an `error`, and the transformed item from `arr`. If `iterator` passes an error to its
+callback, the main `callback` (for the `map` function) is immediately called with the error.
+
+Note, that since this function applies the `iterator` to each item in parallel,
+there is no guarantee that the `iterator` functions will complete in order.
+However, the results array will be in the same order as the original `arr`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, transformed)` which must be called once
+  it has completed with an error (which can be `null`) and a transformed item.
+* `callback(err, results)` - *Optional* A callback which is called when all `iterator`
+  functions have finished, or an error occurs. Results is an array of the
+  transformed items from the `arr`.
+
+__Example__
+
+```js
+async.map(['file1','file2','file3'], fs.stat, function(err, results){
+    // results is now an array of stats for each file
+});

+
+<a name="select" />
+<a name="filter" />
+### filter(arr, iterator, [callback])
+
+__Alias:__ `select`
+
+Returns a new array of all the values in `arr` which pass an async truth test.
+_The callback for each `iterator` call only accepts a single argument of `true` or
+`false`; it does not accept an error argument first!_ This is in-line with the
+way node libraries work with truth tests like `fs.exists`. This operation is
+performed in parallel, but the results array will be in the same order as the
+original.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The `iterator` is passed a `callback(truthValue)`, which must be called with a
+  boolean argument once it has completed.
+* `callback(results)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished.
+
+__Example__
+
+```js
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+```

+<a name="reject" />
+### reject(arr, iterator, [callback])
+

+

+* rejectSeries(arr, iterator, [callback])
+* rejectLimit(arr, limit, iterator, [callback])
+
+---------------------------------------
+
+<a name="reduce" />
+### reduce(arr, memo, iterator, [callback])
+
+__Aliases:__ `inject`, `foldl`
+
+Reduces `arr` into a single value using an async `iterator` to return
+each successive step. `memo` is the initial state of the reduction.
+This function only operates in series.
+
+For performance reasons, it may make sense to split a call to this function into
+a parallel map, and then use the normal `Array.prototype.reduce` on the results.
+This function is for situations where each step in the reduction needs to be async;
+if you can get the data before reducing it, then it's probably a good idea to do so.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `memo` - The initial state of the reduction.
+* `iterator(memo, item, callback)` - A function applied to each item in the
+  array to produce the next step in the reduction. The `iterator` is passed a
+  `callback(err, reduction)` which accepts an optional error as its first
+  argument, and the state of the reduction as the second. If an error is
+  passed to the callback, the reduction is stopped and the main `callback` is
+  immediately called with the error.
+* `callback(err, result)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished. Result is the reduced value.
+
+__Example__
+
+```js
+async.reduce([1,2,3], 0, function(memo, item, callback){
+    // pointless async:
+    process.nextTick(function(){
+        callback(null, memo + item)
+    });
+}, function(err, result){
+    // result is now equal to the last value of memo, which is 6
+});
+```
+
+---------------------------------------
+
+<a name="reduceRight" />
+### reduceRight(arr, memo, iterator, [callback])
+
+__Alias:__ `foldr`
+
+Same as [`reduce`](#reduce), only operates on `arr` in reverse order.
+
+
+---------------------------------------
+
+<a name="detect" />
+### detect(arr, iterator, [callback])
+
+Returns the first value in `arr` that passes an async truth test. The
+`iterator` is applied in parallel, meaning the first iterator to return `true` will
+fire the detect `callback` with that result. That means the result might not be
+the first item in the original `arr` (in terms of order) that passes the test.
+
+If order within the original `arr` is important, then look at [`detectSeries`](#detectSeries).
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The iterator is passed a `callback(truthValue)` which must be called with a
+  boolean argument once it has completed. **Note: this callback does not take an error as its first argument.**
+* `callback(result)` - *Optional* A callback which is called as soon as any iterator returns
+  `true`, or after all the `iterator` functions have finished. Result will be
+  the first item in the array that passes the truth test (iterator) or the
+  value `undefined` if none passed.  **Note: this callback does not take an error as its first argument.**
+
+__Example__
+
+```js

+    // result now equals the first file in the list that exists
+});

+<a name="sortBy" />
+### sortBy(arr, iterator, [callback])
+
+Sorts a list by the results of running each `arr` value through an async `iterator`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, sortValue)` which must be called once it
+  has completed with an error (which can be `null`) and a value to use as the sort
+  criteria.
+* `callback(err, results)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished, or an error occurs. Results is the items from
+  the original `arr` sorted by the values returned by the `iterator` calls.
+
+__Example__
+
+```js
+async.sortBy(['file1','file2','file3'], function(file, callback){
+    fs.stat(file, function(err, stats){
+        callback(err, stats.mtime);
+    });
+}, function(err, results){
+    // results is now the original array of files sorted by
+    // modified date
+});
+```
+
+__Sort Order__
+
+By modifying the callback parameter the sorting order can be influenced:
+
+```js
+//ascending order
+async.sortBy([1,9,3,5], function(x, callback){
+    callback(null, x);
+}, function(err,result){
+    //result callback
+} );

+## Control Flow
+
+<a name="series" />
+### series(tasks, [callback])
+
+Run the functions in the `tasks` array in series, each one running once the previous
+function has completed. If any functions in the series pass an error to its
+callback, no more functions are run, and `callback` is immediately called with the value of the error.
+Otherwise, `callback` receives an array of results when `tasks` have completed.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function, and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from
+[`series`](#series).
+
+**Note** that while many implementations preserve the order of object properties, the
+[ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
+explicitly states that
+
+> The mechanics and order of enumerating the properties is not specified.
+
+So if you rely on the order in which your series of functions are executed, and want
+this to work on all platforms, consider using an array.
+
+__Arguments__
+
+* `tasks` - An array or object containing functions to run, each function is passed
+  a `callback(err, result)` it must call on completion with an error `err` (which can
+  be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed. This function gets a results array (or object) containing all
+  the result arguments passed to the `task` callbacks.
+
+__Example__
+
+```js
+async.series([

+<a name="parallel" />
+### parallel(tasks, [callback])
+
+Run the `tasks` array of functions in parallel, without waiting until the previous
+function has completed. If any of the functions pass an error to its
+callback, the main `callback` is immediately called with the value of the error.
+Once the `tasks` have completed, the results are passed to the final `callback` as an
+array.
+
+**Note:** `parallel` is about kicking-off I/O tasks in parallel, not about parallel execution of code.  If your tasks do not use any timers or perform any I/O, they will actually be executed in series.  Any synchronous setup sections for each task will happen one after the other.  JavaScript remains single-threaded.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from
+[`parallel`](#parallel).
+
+
+__Arguments__
+
+* `tasks` - An array or object containing functions to run. Each function is passed
+  a `callback(err, result)` which it must call on completion with an error `err`
+  (which can be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed successfully. This function gets a results array (or object) containing all
+  the result arguments passed to the task callbacks.
+
+__Example__
+
+```js
+async.parallel([
+    function(callback){
+        setTimeout(function(){

+
+__Arguments__
+
+* `tasks` - An array of functions to run, each function is passed a
+  `callback(err, result1, result2, ...)` it must call on completion. The first
+  argument is an error (which can be `null`) and any further arguments will be
+  passed as arguments in order to the next task.
+* `callback(err, [results])` - An optional callback to run once all the functions
+  have completed. This will be passed the results of the last task's callback.

+<a name="queue" />
+### queue(worker, [concurrency])
+
+Creates a `queue` object with the specified `concurrency`. Tasks added to the
+`queue` are processed in parallel (up to the `concurrency` limit). If all
+`worker`s are in progress, the task is queued until one becomes available.
+Once a `worker` completes a `task`, that `task`'s callback is called.
+
+__Arguments__
+
+* `worker(task, callback)` - An asynchronous function for processing a queued
+  task, which must call its `callback(err)` argument when finished, with an
+  optional `error` as an argument.  If you want to handle errors from an individual task, pass a callback to `q.push()`.
+* `concurrency` - An `integer` for determining how many `worker` functions should be
+  run in parallel.  If omitted, the concurrency defaults to `1`.  If the concurrency is `0`, an error is thrown.
+
+__Queue objects__
+
+The `queue` object returned by this function has the following properties and
+methods:
+
+* `length()` - a function returning the number of items waiting to be processed.
+* `started` - a function returning whether or not any items have been pushed and processed by the queue
+* `running()` - a function returning the number of items currently being processed.
+* `workersList()` - a function returning the array of items currently being processed.
+* `idle()` - a function returning false if there are items waiting or being processed, or true if not.
+* `concurrency` - an integer for determining how many `worker` functions should be
+  run in parallel. This property can be changed after a `queue` is created to
+  alter the concurrency on-the-fly.
+* `push(task, [callback])` - add a new task to the `queue`. Calls `callback` once
+  the `worker` has finished processing the task. Instead of a single task, a `tasks` array
+  can be submitted. The respective callback is used for every task in the list.
+* `unshift(task, [callback])` - add a new task to the front of the `queue`.
+* `saturated` - a callback that is called when the `queue` length hits the `concurrency` limit,
+   and further tasks will be queued.
+* `empty` - a callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - a callback that is called when the last item from the `queue` has returned from the `worker`.
+* `paused` - a boolean for determining whether the queue is in a paused state
+* `pause()` - a function that pauses the processing of tasks until `resume()` is called.
+* `resume()` - a function that resumes the processing of queued tasks when the queue is paused.
+* `kill()` - a function that removes the `drain` callback and empties remaining tasks from the queue forcing it to go idle.
+
+__Example__
+
+```js
+// create a queue object with concurrency 2
+
+var q = async.queue(function (task, callback) {
+    console.log('hello ' + task.name);
+    callback();
+}, 2);

+
+<a name="priorityQueue" />
+### priorityQueue(worker, concurrency)
+
+The same as [`queue`](#queue) only tasks are assigned a priority and completed in ascending priority order. There are two differences between `queue` and `priorityQueue` objects:
+
+* `push(task, priority, [callback])` - `priority` should be a number. If an array of
+  `tasks` is given, all tasks will be assigned the same priority.
+* The `unshift` method was removed.
+
+---------------------------------------
+
+<a name="cargo" />
+### cargo(worker, [payload])
+
+Creates a `cargo` object with the specified payload. Tasks added to the
+cargo will be processed altogether (up to the `payload` limit). If the
+`worker` is in progress, the task is queued until it becomes available. Once
+the `worker` has completed some tasks, each callback of those tasks is called.
+Check out [these](https://camo.githubusercontent.com/6bbd36f4cf5b35a0f11a96dcd2e97711ffc2fb37/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130382f62626330636662302d356632392d313165322d393734662d3333393763363464633835382e676966) [animations](https://camo.githubusercontent.com/f4810e00e1c5f5f8addbe3e9f49064fd5d102699/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130312f38346339323036362d356632392d313165322d383134662d3964336430323431336266642e676966) for how `cargo` and `queue` work.
+
+While [queue](#queue) passes only one task to one of a group of workers
+at a time, cargo passes an array of tasks to a single worker, repeating
+when the worker is finished.
+
+__Arguments__
+
+* `worker(tasks, callback)` - An asynchronous function for processing an array of
+  queued tasks, which must call its `callback(err)` argument when finished, with
+  an optional `err` argument.
+* `payload` - An optional `integer` for determining how many tasks should be
+  processed per round; if omitted, the default is unlimited.
+
+__Cargo objects__
+
+The `cargo` object returned by this function has the following properties and
+methods:
+
+* `length()` - A function returning the number of items waiting to be processed.
+* `payload` - An `integer` for determining how many tasks should be
+  process per round. This property can be changed after a `cargo` is created to
+  alter the payload on-the-fly.
+* `push(task, [callback])` - Adds `task` to the `queue`. The callback is called
+  once the `worker` has finished processing the task. Instead of a single task, an array of `tasks`
+  can be submitted. The respective callback is used for every task in the list.
+* `saturated` - A callback that is called when the `queue.length()` hits the concurrency and further tasks will be queued.
+* `empty` - A callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - A callback that is called when the last item from the `queue` has returned from the `worker`.
+* `idle()`, `pause()`, `resume()`, `kill()` - cargo inherits all of the same methods and event calbacks as [`queue`](#queue)
+
+__Example__
+
+```js
+// create a cargo object with payload 2
+
+var cargo = async.cargo(function (tasks, callback) {
+    for(var i=0; i<tasks.length; i++){
+      console.log('hello ' + tasks[i].name);
+    }
+    callback();
+}, 2);
+
+
+// add some items
+
+cargo.push({name: 'foo'}, function (err) {
+    console.log('finished processing foo');
+});
+cargo.push({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+cargo.push({name: 'baz'}, function (err) {
+    console.log('finished processing baz');
+});
+```
+
+---------------------------------------
+
+<a name="auto" />
+### auto(tasks, [concurrency], [callback])
+
+Determines the best order for running the functions in `tasks`, based on their requirements. Each function can optionally depend on other functions being completed first, and each function is run as soon as its requirements are satisfied.
+
+If any of the functions pass an error to their callback, the `auto` sequence will stop. Further tasks will not execute (so any other functions depending on it will not run), and the main `callback` is immediately called with the error.  Functions also receive an object containing the results of functions which have completed so far.
+
+Note, all functions are called with a `results` object as a second argument,
+so it is unsafe to pass functions in the `tasks` object which cannot handle the
+extra argument.
+
+For example, this snippet of code:
+
+```js
+async.auto({
+  readData: async.apply(fs.readFile, 'data.txt', 'utf-8')
+}, callback);
+```
+
+will have the effect of calling `readFile` with the results object as the last
+argument, which will fail:
+
+```js
+fs.readFile('data.txt', 'utf-8', cb, {});
+```
+
+Instead, wrap the call to `readFile` in a function which does not forward the
+`results` object:
+
+```js
+async.auto({
+  readData: function(cb, results){
+    fs.readFile('data.txt', 'utf-8', cb);
+  }
+}, callback);
+```
+
+__Arguments__
+
+* `tasks` - An object. Each of its properties is either a function or an array of
+  requirements, with the function itself the last item in the array. The object's key
+  of a property serves as the name of the task defined by that property,
+  i.e. can be used when specifying requirements for other tasks.
+  The function receives two arguments: (1) a `callback(err, result)` which must be
+  called when finished, passing an `error` (which can be `null`) and the result of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions.
+* `concurrency` - An optional `integer` for determining the maximum number of tasks that can be run in parallel. By default, as many as possible.
+* `callback(err, results)` - An optional callback which is called when all the
+  tasks have been completed. It receives the `err` argument if any `tasks`
+  pass an error to their callback. Results are always returned; however, if
+  an error occurs, no further `tasks` will be performed, and the results
+  object will only contain partial results.
+
+
+__Example__
+
+```js
+async.auto({
+    get_data: function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    make_folder: function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    },
+    write_file: ['get_data', 'make_folder', function(callback, results){
+        console.log('in write_file', JSON.stringify(results));
+        // once there is some data and the directory exists,
+        // write the data to a file in the directory
+        callback(null, 'filename');
+    }],
+    email_link: ['write_file', function(callback, results){
+        console.log('in email_link', JSON.stringify(results));
+        // once the file is written let's email a link to it...
+        // results.write_file contains the filename returned by write_file.
+        callback(null, {'file':results.write_file, 'email':'user@example.com'});
+    }]
+}, function(err, results) {
+    console.log('err = ', err);
+    console.log('results = ', results);
+});
+```
+
+This is a fairly trivial example, but to do this using the basic parallel and
+series functions would look like this:
+
+```js
+async.parallel([
+    function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    }
+],
+function(err, results){
+    async.series([
+        function(callback){
+            console.log('in write_file', JSON.stringify(results));
+            // once there is some data and the directory exists,
+            // write the data to a file in the directory
+            results.push('filename');
+            callback(null);
+        },
+        function(callback){
+            console.log('in email_link', JSON.stringify(results));
+            // once the file is written let's email a link to it...
+            callback(null, {'file':results.pop(), 'email':'user@example.com'});
+        }
+    ]);
+});
+```
+
+For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding
+new tasks much easier (and the code more readable).
+
+
+---------------------------------------
+
+<a name="retry" />
+### retry([opts = {times: 5, interval: 0}| 5], task, [callback])
+
+Attempts to get a successful response from `task` no more than `times` times before
+returning an error. If the task is successful, the `callback` will be passed the result
+of the successful task. If all attempts fail, the callback will be passed the error and
+result (if any) of the final attempt.
+
+__Arguments__
+
+* `opts` - Can be either an object with `times` and `interval` or a number.
+  * `times` - The number of attempts to make before giving up.  The default is `5`.
+  * `interval` - The time to wait between retries, in milliseconds.  The default is `0`.
+  * If `opts` is a number, the number specifies the number of times to retry, with the default interval of `0`. 
+* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)`
+  which must be called when finished, passing `err` (which can be `null`) and the `result` of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions (if nested inside another control flow).
+* `callback(err, results)` - An optional callback which is called when the
+  task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`.
+
+The [`retry`](#retry) function can be used as a stand-alone control flow by passing a callback, as shown below:
+
+```js
+// try calling apiMethod 3 times
+async.retry(3, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod 3 times, waiting 200 ms between each retry 
+async.retry({times: 3, interval: 200}, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod the default 5 times no delay between each retry 
+async.retry(apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+It can also be embedded within other control flow functions to retry individual methods
+that are not as reliable, like this:
+
+```js
+async.auto({
+    users: api.getUsers.bind(api),
+    payments: async.retry(3, api.getPayments.bind(api))
+}, function(err, results) {
+  // do something with the results
+});
+```
+
+
+---------------------------------------
+
+<a name="iterator" />
+### iterator(tasks)
+
+Creates an iterator function which calls the next function in the `tasks` array,
+returning a continuation to call the next one after that. It's also possible to
+“peek” at the next iterator with `iterator.next()`.
+
+This function is used internally by the `async` module, but can be useful when
+you want to manually control the flow of functions in series.
+
+__Arguments__
+
+* `tasks` - An array of functions to run.
+
+__Example__
+
+```js
+var iterator = async.iterator([
+    function(){ sys.p('one'); },
+    function(){ sys.p('two'); },
+    function(){ sys.p('three'); }
+]);
+
+node> var iterator2 = iterator();
+'one'
+node> var iterator3 = iterator2();
+'two'
+node> iterator3();
+'three'
+node> var nextfn = iterator2.next();
+node> nextfn();
+'three'
+```
+
+---------------------------------------
+
+<a name="apply" />
+### apply(function, arguments..)
+
+Creates a continuation function with some arguments already applied.
+
+Useful as a shorthand when combined with other control flow functions. Any arguments
+passed to the returned function are added to the arguments originally passed
+to apply.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to automatically apply when the
+  continuation is called.
+
+__Example__
+
+```js
+// using apply
+
+async.parallel([
+    async.apply(fs.writeFile, 'testfile1', 'test1'),
+    async.apply(fs.writeFile, 'testfile2', 'test2'),
+]);
+
+
+// the same process without using apply
+
+async.parallel([
+    function(callback){
+        fs.writeFile('testfile1', 'test1', callback);
+    },
+    function(callback){
+        fs.writeFile('testfile2', 'test2', callback);
+    }
+]);
+```
+
+It's possible to pass any number of additional arguments when calling the
+continuation:
+
+```js
+node> var fn = async.apply(sys.puts, 'one');
+node> fn('two', 'three');
+one
+two
+three
+```
+
+---------------------------------------
+
+<a name="nextTick" />
+### nextTick(callback), setImmediate(callback)
+
+Calls `callback` on a later loop around the event loop. In Node.js this just
+calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)`
+if available, otherwise `setTimeout(callback, 0)`, which means other higher priority
+events may precede the execution of `callback`.
+
+This is used internally for browser-compatibility purposes.
+
+__Arguments__
+
+* `callback` - The function to call on a later loop around the event loop.
+
+__Example__
+
+```js
+var call_order = [];
+async.nextTick(function(){
+    call_order.push('two');
+    // call_order now equals ['one','two']
+});
+call_order.push('one')
+```
+
+<a name="times" />
+### times(n, iterator, [callback])
+
+Calls the `iterator` function `n` times, and accumulates results in the same manner
+you would use with [`map`](#map).
+
+__Arguments__
+
+* `n` - The number of times to run the function.
+* `iterator` - The function to call `n` times.
+* `callback` - see [`map`](#map)
+
+__Example__
+
+```js
+// Pretend this is some complicated async factory
+var createUser = function(id, callback) {
+  callback(null, {
+    id: 'user' + id
+  })
+}
+// generate 5 users
+async.times(5, function(n, next){
+    createUser(n, function(err, user) {
+      next(err, user)
+    })
+}, function(err, users) {
+  // we should now have 5 users
+});
+```

+
+## Utils
+
+<a name="memoize" />
+### memoize(fn, [hasher])
+
+Caches the results of an `async` function. When creating a hash to store function
+results against, the callback is omitted from the hash and an optional hash
+function can be used.
+
+If no hash function is specified, the first argument is used as a hash key, which may work reasonably if it is a string or a data type that converts to a distinct string. Note that objects and arrays will not behave reasonably. Neither will cases where the other arguments are significant. In such cases, specify your own hash function.
+
+The cache of results is exposed as the `memo` property of the function returned
+by `memoize`.
+
+__Arguments__
+
+* `fn` - The function to proxy and cache results from.
+* `hasher` - An optional function for generating a custom hash for storing
+  results. It has all the arguments applied to it apart from the callback, and
+  must be synchronous.
+
+__Example__
+
+```js
+var slow_fn = function (name, callback) {
+    // do something
+    callback(null, result);
+};
+var fn = async.memoize(slow_fn);
+
+// fn can now be used as if it were slow_fn
+fn('some name', function () {
+    // callback
+});
+```
+
+<a name="unmemoize" />
+### unmemoize(fn)
+
+Undoes a [`memoize`](#memoize)d function, reverting it to the original, unmemoized
+form. Handy for testing.
+
+__Arguments__
+
+* `fn` - the memoized function
+
+---------------------------------------
+
+<a name="ensureAsync" />
+### ensureAsync(fn)
+
+Wrap an async function and ensure it calls its callback on a later tick of the event loop.  If the function already calls its callback on a next tick, no extra deferral is added. This is useful for preventing stack overflows (`RangeError: Maximum call stack size exceeded`) and generally keeping [Zalgo](http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony) contained.
+
+__Arguments__
+
+* `fn` - an async function, one that expects a node-style callback as its last argument
+
+Returns a wrapped function with the exact same call signature as the function passed in.
+
+__Example__
+
+```js
+function sometimesAsync(arg, callback) {
+  if (cache[arg]) {
+    return callback(null, cache[arg]); // this would be synchronous!!
+  } else {
+    doSomeIO(arg, callback); // this IO would be asynchronous
+  }
+}
+
+// this has a risk of stack overflows if many results are cached in a row
+async.mapSeries(args, sometimesAsync, done);
+
+// this will defer sometimesAsync's callback if necessary,
+// preventing stack overflows
+async.mapSeries(args, async.ensureAsync(sometimesAsync), done);
+
+```
+
+---------------------------------------
+
+<a name="constant">
+### constant(values...)
+
+Returns a function that when called, calls-back with the values provided.  Useful as the first function in a `waterfall`, or for plugging values in to `auto`.
+
+__Example__
+
+```js
+async.waterfall([
+  async.constant(42),
+  function (value, next) {
+    // value === 42
+  },
+  //...
+], callback);
+
+async.waterfall([
+  async.constant(filename, "utf8"),
+  fs.readFile,
+  function (fileData, next) {
+    //...
+  }
+  //...
+], callback);
+
+async.auto({
+  hostname: async.constant("https://server.net/"),
+  port: findFreePort,
+  launchServer: ["hostname", "port", function (cb, options) {
+    startServer(options, cb);
+  }],
+  //...
+}, callback);
+
+```
+
+---------------------------------------
+
+<a name="asyncify">
+<a name="wrapSync">
+### asyncify(func)
+
+__Alias:__ `wrapSync`
+
+Take a sync function and make it async, passing its return value to a callback. This is useful for plugging sync functions into a waterfall, series, or other async functions. Any arguments passed to the generated function will be passed to the wrapped function (except for the final callback argument). Errors thrown will be passed to the callback.
+
+__Example__
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(JSON.parse),
+  function (data, next) {
+    // data is the result of parsing the text.
+    // If there was a parsing error, it would have been caught.
+  }
+], callback)
+```
+
+If the function passed to `asyncify` returns a Promise, that promises's resolved/rejected state will be used to call the callback, rather than simply the synchronous return value.  Example:
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(function (contents) {
+    return db.model.create(contents);
+  }),
+  function (model, next) {
+    // `model` is the instantiated model object. 
+    // If there was an error, this function would be skipped.
+  }
+], callback)
+```
+
+This also means you can asyncify ES2016 `async` functions.
+
+```js
+var q = async.queue(async.asyncify(async function (file) {
+  var intermediateStep = await processFile(file);
+  return await somePromise(intermediateStep)
+}));
+
+q.push(files);
+```
+
+---------------------------------------
+
+<a name="log" />
+### log(function, arguments)
+
+Logs the result of an `async` function to the `console`. Only works in Node.js or
+in browsers that support `console.log` and `console.error` (such as FF and Chrome).
+If multiple arguments are returned from the async function, `console.log` is
+called on each argument in order.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to apply to the function.
+
+__Example__
+
+```js
+var hello = function(name, callback){
+    setTimeout(function(){
+        callback(null, 'hello ' + name);
+    }, 1000);
+};
+```
+```js
+node> async.log(hello, 'world');
+'hello world'
+```
+
+---------------------------------------
+
+<a name="dir" />
+### dir(function, arguments)
+
+Logs the result of an `async` function to the `console` using `console.dir` to
+display the properties of the resulting object. Only works in Node.js or
+in browsers that support `console.dir` and `console.error` (such as FF and Chrome).
+If multiple arguments are returned from the async function, `console.dir` is
+called on each argument in order.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to apply to the function.
+
+__Example__
+
+```js
+var hello = function(name, callback){
+    setTimeout(function(){
+        callback(null, {hello: name});
+    }, 1000);
+};
+```
+```js
+node> async.dir(hello, 'world');
+{hello: 'world'}
+```
+
+---------------------------------------
+
+<a name="noConflict" />
+### noConflict()
+
+Changes the value of `async` back to its original value, returning a reference to the
+`async` object.

+
+[![build status](https://secure.travis-ci.org/gulpjs/bach.png)](http://travis-ci.org/gulpjs/bach)
+
+Compose your async functions with elegance
+
+## Usage
+
+With Bach, it is very easy to compose async functions to run in series or parallel.
+
+```js
+var bach = require('bach');
+
+function fn1(cb){
+  cb(null, 1);
+}
+
+function fn2(cb){
+  cb(null, 2);
+}
+
+function fn3(cb){
+  cb(null, 3);
+}
+
+var seriesFn = bach.series(fn1, fn2, fn3);
+// fn1, fn2, and fn3 will be run in series
+seriesFn(function(err, res){
+  if(err){ // in this example, err is undefined
+    // handle error
+  }
+  // handle results
+  // in this example, res is [1, 2, 3]
+});
+
+var parallelFn = bach.parallel(fn1, fn2, fn3);
+// fn1, fn2, and fn3 will be run in parallel
+parallelFn(function(err, res){
+  if(err){ // in this example, err is undefined
+    // handle error
+  }
+  // handle results
+  // in this example, res is [1, 2, 3]
+});
+```
+
+Since the composer functions just return a function that can be called, you can combine them.
+
+```js
+var combinedFn = bach.series(fn1, bach.parallel(fn2, fn3));
+// fn1 will be executed before fn2 and fn3 are run in parallel
+combinedFn(function(err, res){
+  if(err){ // in this example, err is undefined
+    // handle error
+  }
+  // handle results
+  // in this example, res is [1, [2, 3]]
+});
+```
+
+Functions are called with [async-done](https://github.com/gulpjs/async-done), so you can return a stream or promise.
+The function will complete when the stream ends/closes/errors or the promise fulfills/rejects.
+
+```js
+// streams
+var fs = require('fs');
+
+function streamFn1(){
+  return fs.createReadStream('./example')
+    .pipe(fs.createWriteStream('./example'));
+}
+
+function streamFn2(){
+  return fs.createReadStream('./example')
+    .pipe(fs.createWriteStream('./example'));
+}
+
+var parallelStreams = bach.parallel(streamFn1, streamFn2);
+parallelStreams(function(err){
+  if(err){ // in this example, err is undefined
+    // handle error
+  }
+  // all streams have emitted an 'end' or 'close' event
+});
+```
+
+```js
+// promises
+var when = require('when');
+
+function promiseFn1(){
+  return when.resolve(1);
+}
+
+function promiseFn2(){
+  return when.resolve(2);
+}
+
+var parallelPromises = bach.parallel(promiseFn1, promiseFn2);
+parallelPromises(function(err, res){
+  if(err){ // in this example, err is undefined
+    // handle error
+  }
+  // handle results
+  // in this example, res is [1, 2]
+});
+```
+
+All errors are caught in a [domain](http://nodejs.org/api/domain.html) and passed to the final callback as the first argument.
+
+```js
+function success(cb){
+  setTimeout(function(){
+    cb(null, 1);
+  }, 500);
+}
+
+function error(){
+  throw new Error('Thrown Error');
+}
+
+var errorThrownFn = bach.parallel(error, success);
+errorThrownFn(function(err, res){
+  if(err){
+    // handle error
+    // in this example, err is an error caught by the domain
+  }
+  // handle results
+  // in this example, res is [undefined]
+});
+```
+
+Something that may be encountered when an error happens in a parallel composition is the callback
+will be called as soon as the error happens. If you want to continue on error and wait until all
+functions have finished before calling the callback, use `settleSeries` or `settleParallel`.
+
+```js
+function success(cb){
+  setTimeout(function(){
+    cb(null, 1);
+  }, 500);
+}
+
+function error(cb){
+  cb(new Error('Async Error'));
+}
+
+var parallelSettlingFn = bach.settleParallel(success, error);
+parallelSettlingFn(function(err, res){
+  // all functions have finished executing
+  if(err){
+    // handle error
+    // in this example, err is an error passed to the callback
+  }
+  // handle results
+  // in this example, res is [1]
+});
+```
+
+## API
+
+__All bach APIs return an invoker function that takes a single callback as its only parameter.
+The function signature is `function(error, results)`.__
+
+Each method can optionally be passed an object of [extension point functions](#extension-points)
+as the last argument.
+
+### `series(fns..., [extensions])` => Function
+
+All functions (`fns`) passed to this function will be called in series when the returned function is
+called.  If an error occurs, execution will stop and the error will be passed to the callback function
+as the first parameter.
+
+__The error parameter will always be a single error.__
+
+### `parallel(fns..., [extensions])` => Function
+
+All functions (`fns`) passed to this function will be called in parallel when the returned
+function is called.  If an error occurs, the error will be passed to the callback function
+as the first parameter. Any async functions that have not completed, will still complete,
+but their results will __not__ be available.
+
+__The error parameter will always be a single error.__
+
+### `settleSeries(fns..., [extensions])` => Function
+
+All functions (`fns`) passed to this function will be called in series when the returned function is
+called. All functions will always be called and the callback will receive all settled errors and results.
+
+__The error parameter will always be an array of errors.__
+
+### `settleParallel(fns..., [extensions])` => Function
+
+All functions (`fns`) passed to this function will be called in parallel when the returned function is
+called. All functions will always be called and the callback will receive all settled errors and results.
+
+__The error parameter will always be an array of errors.__
+
+### Extension Points
+
+An extension point object can contain:
+
+#### `create(fn, key)` => `storage` object
+
+Called before the async function or extension points are called. Receives the function and key to be
+executed in the future.  The return value should be any object and will be passed to the other extension
+point methods.  The storage object can keep any information needed between extension points and can
+be mutated within extension points.
+
+#### `before(storage)`
+
+Called before the async function is executed. Receives the storage object returned from the `create`
+extension point.
+
+#### `after(storage)`
+
+Called after the async function is executed and completes successfully. Receives the storage object
+returned from the `create` extension point.
+
+#### `error(storage)`
+
+Called after the async function is executed and errors. Receives the storage object returned from
+the `create` extension point.

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install balanced-match

+> Plugin that post-processes the argv object from simplify how args are mapped to options, tasks and generators.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install base-argv --save
+```
+
+## Usage
+
+Use as a plugin with [base](https://github.com/node-base/base).
+
+```js
+var Base = require('base');
+var argv = require('base-argv');
+
+var app = new Base();
+app.use(argv());
+
+// parse argv
+var args = app.argv(['foo', 'bar', '--set=a:b']);
+console.log(args);
+```
+
+Results in:
+
+```js
+{ set: { a: 'b' }, tasks: [ 'foo', 'bar' ] }
+```
+
+This object can then be passed to something else for further processing.

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+> Normalizers for common argv commands handled by the base-cli plugin. Also pre-processes the given object with base-cli-schema before calling `.process()`
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-cli-process
+```
+
+## Usage
+
+Normalizes the given object with [base-cli-schema](https://github.com/jonschlinkert/base-cli-schema) before calling the `.process` method from [base-cli](https://github.com/node-base/base-cli).
+
+```js
+var Base = require('base');
+var cli = require('base-cli-process');
+
+var app = new Base();
+app.use(cli());
+
+var pkg = require('./package');
+
+app.cli.process(pkg, function(err) {
+  if (err) throw err;
+});
+```
+
+## API
+
+### [.asyncHelpers](lib/fields/asyncHelpers.js#L15)
+
+Load and register async template helpers from a glob or filepath.
+
+**Example**
+
+```sh
+$ app --asyncHelpers="foo.js"
+```
+
+### [.config](lib/fields/config.js#L32)
+
+Persist a value to a namespaced config object in package.json. For example, if you're using `verb`, the value would be saved to the `verb` object.
+
+**Params**
+
+* **{Object}**: app
+
+**Example**
+
+```sh
+# display the config
+$ app --config
+# set a boolean for the current project
+$ app --config=toc
+# save the cwd to use for the current project
+$ app --config=cwd:foo
+# save the tasks to run for the current project
+$ app --config=tasks:readme
+```
+
+### [.cwd](lib/fields/cwd.js#L17)
+
+Set the `--cwd` to use in the current project.
+
+**Example**
+
+```sh
+$ app --cwd=foo
+```
+
+### [.data](lib/fields/data.js#L23)
+
+Define data to be used for rendering templates.
+
+**Example**
+
+```sh
+$ app --data=foo:bar
+# {foo: 'bar'}
+
+$ app --data=foo.bar:baz
+# {foo: {bar: 'baz'}}
+
+$ app --data=foo:bar,baz
+# {foo: ['bar', 'baz']}}
+```
+
+### [.del](lib/fields/del.js#L20)
+
+Delete a value from `app`.
+
+**Example**
+
+```json
+# delete a value from package.json config (e.g. `verb` object)
+$ app --del=config.foo
+# delete a value from in-memory options
+$ app --del=option.foo
+# delete a property from the global config store
+$ app --del=globals.foo
+```
+
+### [.dest](lib/fields/dest.js#L17)
+
+Set a `dest` path on `app.options`.
+
+**Example**
+
+```sh
+$ app --dest=foo
+```
+

+### [.set](lib/fields/set.js#L17)
+
+Set the given value, or a value was previously cached by `--get`.
+
+**Example**
+
+```json
+$ app --set=pkg.name:foo
+# example: persist `pkg.name` to `store.data.name`
+$ app --get=pkg.name --set=store.name
+```
+
+### [.get](lib/fields/show.js#L16)
+
+Get a value from `app` and set it on `app.cache.get` in memory, allowing the value to be re-used by another command, like `--set`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# base-cli [![NPM version](https://img.shields.io/npm/v/base-cli.svg?style=flat)](https://www.npmjs.com/package/base-cli) [![NPM downloads](https://img.shields.io/npm/dm/base-cli.svg?style=flat)](https://npmjs.org/package/base-cli) [![Build Status](https://img.shields.io/travis/node-base/base-cli.svg?style=flat)](https://travis-ci.org/node-base/base-cli)
+
+> Plugin for base-methods that maps built-in methods to CLI args (also supports methods from a few plugins, like 'base-store', 'base-options' and 'base-data'.
+
+You might also be interested in [base-config](https://github.com/node-base/base-config).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install base-cli --save
+```
+
+Adds a `cli` method to `base` for mapping parsed command line arguments existing [base](https://github.com/node-base/base) methods or custom functions.
+
+The goal is to simplify the process of settings up command line logic for your [base](https://github.com/node-base/base) application.
+
+## Usage
+
+```js
+var cli = require('base-cli');
+var Base = require('base');
+var app = new Base();
+
+// register the plugin
+app.use(cli());
+```
+
+## API
+
+This adds a `cli` object to [base](https://github.com/node-base/base) with the following (chainable) methods (`base.cli.*`):
+
+* `.map()` -  [.map](#map): add mappings from command line flags/options to custom functions or `base` methods
+* `.alias()` -  [.alias](#alias): similar to `map` but creates simple aliases. For example, `alias('show', 'get')` would invoke the `.get()` method when `--show` is passed on the command line
+* `.process()` -  [.process](#process): once all mappings are defined, pass `argv` to `.process()` to iterate over the mappings, passing `argv` as context.
+
+## Example
+
+```js
+var argv = require('minimist')(process.argv.slice(2));
+var expand = require('expand-args');
+var cli = require('base-cli');
+var Base = require('base');
+
+var app = new Base();
+app.use(cli());
+
+app.cli
+  .map('get', function(key, val) {
+    app.get(key, val);
+  })
+  .map('set', function(key, val) {
+    app.set(key, val);
+  })
+
+app.cli.process(expand(argv), function(err) {
+  if (err) throw err;
+});
+
+// command line args:
+//   
+//   '--set=a:b --get=a'
+//   
+// prints:
+//   
+//   'a'
+//   
+```

+
+Schema for the base-config plugin, used for normalizing config values before passing them to config.process().
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-config-schema
+```
+
+## Usage
+
+```js
+var Base = require('base');
+var config = require('base-config');
+var configSchema = require('base-config-schema');
+
+var app = new Base();
+app.use(config());
+var schema = configSchema(app);
+
+var pkg = require('./package');
+var obj = schema.normalize(pkg.verb);
+
+app.config.process(obj, function(err) {
+  if (err) throw err;
+});
+```
+
+## API
+
+### [.asyncHelpers](lib/fields/asyncHelpers.js#L21)
+
+Register async template helpers. Can be an array of module names or filepaths, or an object where the keys are filepaths or module names, and the values are options objects.
+
+**Example**
+
+```js
+{
+  "asyncHelpers": ["helper-foo", "helper-bar"]
+}
+```
+
+### [.disable](lib/fields/disable.js#L16)
+
+Disable one or more options. This is the API-equivalent of calling `app.disable('foo')`, or `app.option('foo', false)`.
+
+**Example**
+
+```js
+{disable: 'foo'}
+// or
+{disable: ['foo', 'bar']}
+```
+
+### [.enable](lib/fields/enable.js#L16)
+
+Enable one or more options. This is the API-equivalent of calling `app.enable('foo')`, or `app.option('foo', false)`.
+
+**Example**
+
+```js
+{enable: 'foo'}
+// or
+{enable: ['foo', 'bar']}
+```

+Remove duplicate values from an array. Fastest ES5 implementation.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save array-unique
+```
+
+## Usage
+
+```js
+var unique = require('array-unique');
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c']
+
+/* The above modifies the input array. To prevent that at a slight performance cost: */
+var unique = require("array-unique").immutable;
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c', 'c']

+# clone
+
+[![build status](https://secure.travis-ci.org/pvorb/clone.svg)](http://travis-ci.org/pvorb/clone) [![downloads](https://img.shields.io/npm/dt/clone.svg)](http://npm-stat.com/charts.html?package=clone)
+
+offers foolproof _deep cloning_ of objects, arrays, numbers, strings, maps,
+sets, promises, etc. in JavaScript.
+
+**XSS vulnerability detected**
+
+
+## Installation
+
+    npm install clone
+
+(It also works with browserify, ender or standalone. You may want to use the
+option `noParse` in browserify to reduce the resulting file size, since usually
+`Buffer`s are not needed in browsers.)
+
+
+## Example
+
+~~~ javascript
+var clone = require('clone');
+
+var a, b;
+
+a = { foo: { bar: 'baz' } };  // initial value of a
+
+b = clone(a);                 // clone a -> b
+a.foo.bar = 'foo';            // change a
+
+console.log(a);               // show a
+console.log(b);               // show b
+~~~
+
+This will print:
+
+~~~ javascript
+{ foo: { bar: 'foo' } }
+{ foo: { bar: 'baz' } }
+~~~
+
+**clone** masters cloning simple objects (even with custom prototype), arrays,
+Date objects, and RegExp objects. Everything is cloned recursively, so that you
+can clone dates in arrays in objects, for example.
+
+
+## API
+
+`clone(val, circular, depth)`
+
+  * `val` -- the value that you want to clone, any type allowed
+  * `circular` -- boolean
+
+    Call `clone` with `circular` set to `false` if you are certain that `obj`
+    contains no circular references. This will give better performance if
+    needed. There is no error if `undefined` or `null` is passed as `obj`.
+  * `depth` -- depth to which the object is to be cloned (optional,
+    defaults to infinity)
+  * `prototype` -- sets the prototype to be used when cloning an object.
+    (optional, defaults to parent prototype).
+  * `includeNonEnumerable` -- set to `true` if the non-enumerable properties
+    should be cloned as well. Non-enumerable properties on the prototype chain
+    will be ignored. (optional, defaults to `false`)
+
+`clone.clonePrototype(obj)`
+
+  * `obj` -- the object that you want to clone
+
+Does a prototype clone as
+[described by Oran Looney](http://oranlooney.com/functional-javascript/).
+
+
+## Circular References
+
+~~~ javascript
+var a, b;
+
+a = { hello: 'world' };
+
+a.myself = a;
+b = clone(a);
+
+console.log(b);
+~~~
+
+This will print:
+
+~~~ javascript
+{ hello: "world", myself: [Circular] }
+~~~
+
+So, `b.myself` points to `b`, not `a`. Neat!
+

+be cloneable. If you find other objects that cannot be cloned, please [open an
+issue](https://github.com/pvorb/clone/issues/new).
+
+
+## Bugs and Issues
+
+If you encounter any bugs or issues, feel free to [open an issue at
+github](https://github.com/pvorb/clone/issues) or send me an email to
+<paul@vorba.ch>. I also always like to hear from you, if you’re using my code.

+
+```sh
+$ npm install --save file-contents
+```
+
+This is inspired by the code in [vinyl-fs](http://github.com/wearefractal/vinyl-fs) `src`. I needed a function that essentially did the same thing but could be used with stream or non-stream code.
+
+## Usage
+
+```js
+var through = require('through2');
+var contents = require('file-contents');
+
+function toStream(fp) {
+  var stream = through.obj();
+  stream.write({path: fp});
+  stream.end();
+  return stream;
+}
+
+toStream('README.md')
+  .pipe(contents())
+  .on('data', function(file) {
+    console.log(file.contents.toString());
+  });
+
+```
+
+**async**
+
+An `.async()` method is exposed for non-stream, async usage.
+
+```js
+contents.async({path: 'README.md'}, function (err, file) {
+  // results in something like:
+  // 
+  //   { path: 'README.md',
+  //   stat:
+  //    { dev: 16777218,
+  //      mode: 33188,
+  //      nlink: 1,
+  //      uid: 501,
+  //      gid: 20,
+  //      rdev: 0,
+  //      blksize: 4096,
+  //      ino: 26436116,
+  //      size: 2443,
+  //      blocks: 8,
+  //      atime: Fri Jul 17 2015 03:01:54 GMT-0400 (EDT),

+  // contents: <Buffer 23 20 66 69 6c 65 2d 63 6f 6e 74 65 6e 74 73 20 5b 21 5b 4e 50 4d 20 76 65 72 73 69 6f 6e 5d 28 68 74 74 70 73 3a 2f 2f 62 61 64 67 65 2e 66 75 72 79 ... > }
+});
+```
+
+**sync**
+
+A `.sync()` method is exposed for non-stream, sync usage.
+
+```js
+var file = {path: 'README.md'};
+contents.sync(file);
+// results in something like:
+// 
+//   { path: 'README.md',
+//   stat:
+//    { dev: 16777218,
+//      mode: 33188,
+//      nlink: 1,
+//      uid: 501,
+//      gid: 20,
+//      rdev: 0,
+//      blksize: 4096,
+//      ino: 26436116,
+//      size: 2443,
+//      blocks: 8,
+//      atime: Fri Jul 17 2015 03:01:54 GMT-0400 (EDT),
+//      mtime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+//      ctime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+//      birthtime: Tue Jul 14 2015 23:03:58 GMT-0400 (EDT) },
+// contents: <Buffer 23 20 66 69 6c 65 2d 63 6f 6e 74 65 6e 74 73 20 5b 21 5b 4e 50 4d 20 76 65 72 73 69 6f 6e 5d 28 68 74 74 70 73 3a 2f 2f 62 61 64 67 65 2e 66 75 72 79 ... > }
+```
+
+## History
+
+**v0.2.0**
+
+* renames `.getContents` method to `.async`

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i is-accessor-descriptor --save
+```
+
+## Usage
+
+```js
+var isAccessor = require('is-accessor-descriptor');
+
+isAccessor({get: function() {}});
+//=> true
+```
+
+You may also pass an object and property name to check if the property is an accessor:
+
+```js
+isAccessor(foo, 'bar');
+```
+
+## Examples
+
+`false` when not an object
+
+```js
+isAccessor('a')
+isAccessor(null)
+isAccessor([])
+//=> false
+```
+
+`true` when the object has valid properties
+
+and the properties all have the correct JavaScript types:
+
+```js
+isAccessor({get: noop, set: noop})
+isAccessor({get: noop})
+isAccessor({set: noop})
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isAccessor({get: noop, set: noop, bar: 'baz'})
+isAccessor({get: noop, writable: true})
+isAccessor({get: noop, value: true})
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isAccessor({get: noop, set: 'baz'})
+isAccessor({get: 'foo', set: noop})
+isAccessor({get: 'foo', bar: 'baz'})
+isAccessor({get: 'foo', set: 'baz'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isAccessor({get: noop, set: noop, enumerable: 'foo'})
+isAccessor({set: noop, configurable: 'foo'})
+isAccessor({get: noop, configurable: 'foo'})
+//=> false
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript data descriptor.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i is-data-descriptor --save
+```
+
+## Usage
+
+```js
+var isDataDesc = require('is-data-descriptor');
+```
+
+## Examples
+
+`true` when the descriptor has valid properties with valid values.
+
+```js
+// `value` can be anything
+isDataDesc({value: 'foo'})
+isDataDesc({value: function() {}})
+isDataDesc({value: true})
+//=> true
+```
+
+`false` when not an object
+
+```js
+isDataDesc('a')
+//=> false
+isDataDesc(null)
+//=> false
+isDataDesc([])
+//=> false
+```
+
+`false` when the object has invalid properties
+
+```js
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', get: function(){}})
+//=> false
+isDataDesc({get: function(){}, value: 'foo'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDataDesc({value: 'foo', enumerable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', configurable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', writable: 'foo'})
+//=> false
+```
+
+## Valid properties
+
+The only valid data descriptor properties are the following:
+
+* `configurable` (required)
+* `enumerable` (required)
+* `value` (optional)
+* `writable` (optional)
+
+To be a valid data descriptor, either `value` or `writable` must be defined.
+
+**Invalid properties**
+
+A descriptor may have additional _invalid_ properties (an error will **not** be thrown).
+
+```js
+var foo = {};
+
+Object.defineProperty(foo, 'bar', {
+  enumerable: true,
+  whatever: 'blah', // invalid, but doesn't cause an error
+  get: function() {
+    return 'baz';
+  }
+});
+
+console.log(foo.bar);
+//=> 'baz'
+```

+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of is more correct than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly tests instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`

+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+
+> Returns `true` if an array has a glob pattern.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-glob
+```
+
+## Usage
+
+```js
+var hasGlob = require('has-glob');
+
+hasGlob(['foo', 'bar', '*.js']);
+//=> true
+
+hasGlob(['foo', 'bar', 'baz']);
+//=> false
+```
+
+**True**
+
+The following all return `true`:
+
+```js
+hasGlob(['foo', 'bar', '*.js'])
+hasGlob(['foo', 'bar', '!*.js'])
+hasGlob(['foo', 'bar', '!foo'])
+hasGlob(['foo', 'bar', '!foo.js'])
+hasGlob(['foo', 'bar', '**/abc.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/{a,b}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z..2}.js'])
+hasGlob(['foo', 'bar', 'abc/@(a).js'])
+hasGlob(['foo', 'bar', 'abc/!(a).js'])
+hasGlob(['foo', 'bar', 'abc/+(a).js'])
+hasGlob(['foo', 'bar', 'abc/*(a).js'])
+hasGlob(['foo', 'bar', 'abc/?(a).js'])
+hasGlob(['foo', 'bar', 'abc/@.js'])
+hasGlob(['foo', 'bar', 'abc/!.js'])
+hasGlob(['foo', 'bar', 'abc/+.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', 'abc/(aaa|bbb).js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', '?.js'])
+hasGlob(['foo', 'bar', '[abc].js'])
+hasGlob(['foo', 'bar', '[^abc].js'])
+hasGlob(['foo', 'bar', 'a/b/c/[a-z].js'])
+hasGlob(['foo', 'bar', '[a-j]*[^c]b/c'])
+//=> true
+```
+
+Also works with strings:
+
+```js
+hasGlob('*.js')
+hasGlob('!*.js')
+hasGlob('!foo')
+hasGlob('!foo.js')
+hasGlob('**/abc.js')
+hasGlob('abc/*.js')
+//=> true
+```
+
+**False**
+
+The following all return `false`:
+
+```js
+hasGlob([])
+hasGlob([null])
+hasGlob([undefined])
+hasGlob([{}])
+hasGlob(['.'])
+hasGlob(['foo', 'bar', 'aa'])
+hasGlob(['foo', 'bar', 'abc.js'])
+hasGlob(['foo', 'bar', 'abc/def/ghi.js'])
+//=> false
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-accessor-descriptor
+```
+
+## Usage
+
+```js
+var isAccessor = require('is-accessor-descriptor');
+
+isAccessor({get: function() {}});
+//=> true
+```
+
+You may also pass an object and property name to check if the property is an accessor:
+
+```js
+isAccessor(foo, 'bar');
+```
+
+## Examples
+
+`false` when not an object
+
+```js
+isAccessor('a')
+isAccessor(null)
+isAccessor([])
+//=> false
+```
+
+`true` when the object has valid properties
+
+and the properties all have the correct JavaScript types:
+
+```js
+isAccessor({get: noop, set: noop})
+isAccessor({get: noop})
+isAccessor({set: noop})
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isAccessor({get: noop, set: noop, bar: 'baz'})
+isAccessor({get: noop, writable: true})
+isAccessor({get: noop, value: true})
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isAccessor({get: noop, set: 'baz'})
+isAccessor({get: 'foo', set: noop})
+isAccessor({get: 'foo', bar: 'baz'})
+isAccessor({get: 'foo', set: 'baz'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isAccessor({get: noop, set: noop, enumerable: 'foo'})
+isAccessor({set: noop, configurable: 'foo'})
+isAccessor({get: noop, configurable: 'foo'})
+//=> false
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript data descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-data-descriptor
+```
+
+## Usage
+
+```js
+var isDataDesc = require('is-data-descriptor');
+```
+
+## Examples
+
+`true` when the descriptor has valid properties with valid values.
+
+```js
+// `value` can be anything
+isDataDesc({value: 'foo'})
+isDataDesc({value: function() {}})
+isDataDesc({value: true})
+//=> true
+```
+
+`false` when not an object
+
+```js
+isDataDesc('a')
+//=> false
+isDataDesc(null)
+//=> false
+isDataDesc([])
+//=> false
+```
+
+`false` when the object has invalid properties
+
+```js
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', get: function(){}})
+//=> false
+isDataDesc({get: function(){}, value: 'foo'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDataDesc({value: 'foo', enumerable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', configurable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', writable: 'foo'})
+//=> false
+```
+
+## Valid properties
+
+The only valid data descriptor properties are the following:
+
+* `configurable` (required)
+* `enumerable` (required)
+* `value` (optional)
+* `writable` (optional)
+
+To be a valid data descriptor, either `value` or `writable` must be defined.
+
+**Invalid properties**
+
+A descriptor may have additional _invalid_ properties (an error will **not** be thrown).
+
+```js
+var foo = {};
+
+Object.defineProperty(foo, 'bar', {
+  enumerable: true,
+  whatever: 'blah', // invalid, but doesn't cause an error
+  get: function() {
+    return 'baz';
+  }
+});
+
+console.log(foo.bar);
+//=> 'baz'
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false
+isDescriptor({get: noop, configurable: 'foo'});
+//=> false
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Load templates/views using globs, file paths, objects, arrays, or key-value pairs.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save load-templates
+```
+
+## Usage
+
+In addition to what's shown in the below examples, if a glob pattern or valid filepath is passed, a `stat` object will be added to the `file` object as well.
+
+```js
+var Loader = require('load-templates');
+var loader = new Loader([options]);
+var views = loader.load('*.hbs');
+console.log(views);
+```
+
+## Supported formats
+
+```js
+// filepath
+loader.load('a/b/c/some-template.hbs'); 
+
+// array of filepaths
+loader.load([
+  'a/b/c/some-template.hbs',
+  'a/b/c/other-template.hbs'
+]); 
+
+// glob pattern
+loader.load('*.hbs'); 
+
+// array of globs
+loader.load(['*.hbs', '*.tmpl']); 
+
+// object
+loader.load({path: 'foo'});
+
+// key-value 
+loader.load('d', {path: 'd'});
+loader.load('e', {path: 'e'});
+loader.load('f', {path: 'f'});
+
+// object of objects
+loader.load({
+  a: {path: 'a'},
+  b: {path: 'b'},
+  c: {path: 'c'}
+});
+
+// array of objects
+loader.load([
+  {path: 'a'},
+  {path: 'b'},
+  {path: 'c'}
+]);
+
+// array of nested objects
+loader.load([
+  {
+    a: {path: 'test/fixtures/a.md'},
+    b: {path: 'test/fixtures/b.md'},
+    c: {path: 'test/fixtures/c.md'},
+  },
+  {
+    d: {path: 'test/fixtures/d.md'},
+    e: {path: 'test/fixtures/e.md'},
+    f: {path: 'test/fixtures/f.md'},
+  }
+]);
+```
+
+## Options
+
+### options.cwd
+
+Type: `String`
+
+Default: `process.cwd()`
+
+Pass the current working directory to use for resolving paths.
+
+### options.renameKey
+
+Type: `Function`
+
+Default: `file.path` Absolute filepath
+
+Function to modify `file.key`, which is the property used for setting views on `loader.cache`. It works something like this:
+
+```js
+loader.cache[file.key] = file;
+```
+
+## API
+
+### [Loader](index.js#L27)
+
+Create an instance of `Loader` with the given `options`.
+
+**Params**
+
+* `options` **{Object}**
+
+**Example**
+
+```js
+var Loader = require('load-templates');
+var loader = new Loader();
+```
+
+### [.load](index.js#L53)
+
+Load one or more templates from a filepath, glob pattern, object, or array of filepaths, glob patterns or objects. This method detects the type of value to be handled then calls one of the other methods to do the actual loading.
+
+**Params**
+
+* `templates` **{Object}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the views from `loader.cache`
+
+**Example**
+
+```js
+var loader = new Loader();
+console.log(loader.load(['foo/*.hbs', 'bar/*.hbs']));
+console.log(loader.load({path: 'a/b/c.md'}));
+console.log(loader.load('index', {path: 'a/b/c.md'}));
+```
+
+### [.createView](index.js#L94)
+
+Create a `view` object from the given `template`. View objects are instances of [vinyl](https://github.com/gulpjs/vinyl).
+
+**Params**
+
+* `template` **{Object|String}**: Filepath or object with `path` or `contents` properties.
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the view.
+
+**Example**
+
+```js
+console.log(loader.createView('test/fixtures/foo/bar.hbs'));
+console.log(loader.createView('foo/bar.hbs', {cwd: 'test/fixtures'}));
+```
+
+### [.addView](index.js#L144)
+
+Create a view from the given `template` and cache it on `loader.cache`.
+
+**Params**
+
+* `template` **{String|Object}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the `Loader` instance for chaining
+
+**Example**
+
+```js
+var loader = new Loader();
+loader.addView('foo.hbs');
+console.log(loader.cache);
+```
+
+### [.addViews](index.js#L179)
+
+Create from an array or object of `templates` and cache them on `loader.cache`.
+
+**Params**
+
+* `templates` **{Object}**
+* `options` **{Object}**
+
+**Example**
+
+```js
+var loader = new Loader();
+loader.addViews([
+  {path: 'test/fixtures/a.md'},
+  {path: 'test/fixtures/b.md'},
+  {path: 'test/fixtures/c.md'},
+]);
+loader.addViews({
+  d: {path: 'test/fixtures/d.md'},
+  e: {path: 'test/fixtures/e.md'},
+  f: {path: 'test/fixtures/f.md'},
+});
+loader.addViews([{

+### [.globViews](index.js#L226)
+
+Load templates from one or more glob `patterns` with the given `options`, then cache them on `loader.cache`.
+
+**Params**
+
+* `patterns` **{String|Array}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns `loader.cache`
+
+**Example**
+
+```js
+var loader = new Loader();
+var views = loader.globViews('*.hbs', {cwd: 'templates'});

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save matched
+```
+
+## Usage
+
+If non-glob patterns (e.g. file paths) are passed, only paths that exist on the file system are returned.
+
+```js
+var glob = require('matched');
+```
+
+**async**
+
+```js
+glob(['*.js'], function(err, files) {
+  //=> ['utils.js', 'index.js']
+});
+```
+
+**sync**
+
+```js
+var files = glob.sync(['*.js']);
+//=> ['utils.js', 'index.js']
+```
+
+**promise**
+
+```js
+glob.promise(['*.txt'])
+  .then(function(files) {
+    //=> ['a.txt', 'b.txt', 'c.txt']
+  });
+```
+
+**options**
+
+All methods take options as the second argument:
+
+```js
+glob(['*.js'], {cwd: 'test'}, function(err, files) {
+  //=> ['test.js']
+});
+```
+
+## Release history
+
+**v0.4.1**
+
+* Exposes a non-enumerable `cache` property on the returned files array. This is a patch relase since the property does not change the existing API and should not otherwise effect behavior or results.

+# has-glob [![NPM version](https://badge.fury.io/js/has-glob.svg)](http://badge.fury.io/js/has-glob)
+
+> Returns `true` if an array has a glob pattern.
+
+Also get [is-glob](https://www.npmjs.com/package/is-glob) for checking strings for glob patterns.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i has-glob --save
+```
+
+## Usage
+
+```js
+var hasGlob = require('has-glob');
+
+hasGlob(['foo', 'bar', '*.js']);
+//=> true
+
+hasGlob(['foo', 'bar', 'baz']);
+//=> false
+```
+
+**True**
+
+The following all return `true`:
+
+```js
+hasGlob(['foo', 'bar', '*.js'])
+hasGlob(['foo', 'bar', '!*.js'])
+hasGlob(['foo', 'bar', '!foo'])
+hasGlob(['foo', 'bar', '!foo.js'])
+hasGlob(['foo', 'bar', '**/abc.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/{a,b}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z..2}.js'])
+hasGlob(['foo', 'bar', 'abc/@(a).js'])
+hasGlob(['foo', 'bar', 'abc/!(a).js'])
+hasGlob(['foo', 'bar', 'abc/+(a).js'])
+hasGlob(['foo', 'bar', 'abc/*(a).js'])
+hasGlob(['foo', 'bar', 'abc/?(a).js'])
+hasGlob(['foo', 'bar', 'abc/@.js'])
+hasGlob(['foo', 'bar', 'abc/!.js'])
+hasGlob(['foo', 'bar', 'abc/+.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', 'abc/(aaa|bbb).js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', '?.js'])
+hasGlob(['foo', 'bar', '[abc].js'])
+hasGlob(['foo', 'bar', '[^abc].js'])
+hasGlob(['foo', 'bar', 'a/b/c/[a-z].js'])
+hasGlob(['foo', 'bar', '[a-j]*[^c]b/c'])
+//=> true
+```
+
+Also works with strings:
+
+```js
+hasGlob('*.js')
+hasGlob('!*.js')
+hasGlob('!foo')
+hasGlob('!foo.js')
+hasGlob('**/abc.js')
+hasGlob('abc/*.js')
+//=> true
+```
+
+**False**
+
+The following all return `false`:
+
+```js
+hasGlob([])
+hasGlob([null])
+hasGlob([undefined])
+hasGlob([{}])
+hasGlob(['.'])
+hasGlob(['foo', 'bar', 'aa'])
+hasGlob(['foo', 'bar', 'abc.js'])
+hasGlob(['foo', 'bar', 'abc/def/ghi.js'])
+//=> false
+```

+# is-glob [![NPM version](https://badge.fury.io/js/is-glob.svg)](http://badge.fury.io/js/is-glob)  [![Build Status](https://travis-ci.org/jonschlinkert/is-glob.svg)](https://travis-ci.org/jonschlinkert/is-glob)
+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+## What is Vinyl?
+
+Vinyl is a very simple metadata object that describes a file. When you think of a file, two attributes come to mind: `path` and `contents`. These are the main attributes on a Vinyl object. A file does not necessarily represent something on your computer’s file system. You have files on S3, FTP, Dropbox, Box, CloudThingly.io and other services. Vinyl can be used to describe files from all of these sources.
+
+## What is a Vinyl Adapter?
+
+While Vinyl provides a clean way to describe a file, we also need a way to access these files. Each file source needs what I call a "Vinyl adapter". A Vinyl adapter simply exposes a `src(globs)` and a `dest(folder)` method. Each return a stream. The `src` stream produces Vinyl objects, and the `dest` stream consumes Vinyl objects. Vinyl adapters can expose extra methods that might be specific to their input/output medium, such as the `symlink` method [`vinyl-fs`][vinyl-fs] provides.
+
+## Usage
+
+```js
+var Vinyl = require('vinyl');
+
+var jsFile = new Vinyl({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js',
+  contents: new Buffer('var x = 123')
+});
+```
+
+## API
+
+### `new Vinyl([options])`
+
+The constructor is used to create a new instance of `Vinyl`. Each instance represents a separate file, directory or symlink.
+
+All internally managed paths (`cwd`, `base`, `path`, `history`) are normalized and have trailing separators removed. See [Normalization and concatenation][normalization] for more information.
+
+Options may be passed upon instantiation to create a file with specific properties.
+
+#### `options`
+
+Options are not mutated by the constructor.
+
+##### `options.cwd`
+
+The current working directory of the file.
+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.base`
+
+Used for calculating the `relative` property. This is typically where a glob starts.
+
+Type: `String`
+
+Default: `options.cwd`
+
+##### `options.path`
+
+The full path to the file.
+
+Type: `String`
+
+Default: `undefined`
+
+##### `options.history`
+
+Stores the path history. If `options.path` and `options.history` are both passed, `options.path` is appended to `options.history`. All `options.history` paths are normalized by the `file.path` setter.
+
+Type: `Array`
+
+Default: `[]` (or `[options.path]` if `options.path` is passed)
+
+##### `options.stat`
+
+The result of an `fs.stat` call. This is how you mark the file as a directory or symbolic link. See [isDirectory()][is-directory], [isSymbolic()][is-symbolic] and [fs.Stats][fs-stats] for more information.
+
+Type: [`fs.Stats`][fs-stats]
+
+Default: `undefined`
+
+##### `options.contents`
+
+The contents of the file.  If `options.contents` is a [`ReadableStream`][readable-stream], it is wrapped in a [`cloneable-readable`][cloneable-readable] stream.
+
+Type: [`ReadableStream`][readable-stream], [`Buffer`][buffer], or `null`
+
+Default: `null`
+
+##### `options.{custom}`
+
+Any other option properties will be directly assigned to the new Vinyl object.
+
+```js
+var Vinyl = require('vinyl');
+
+var file = new Vinyl({ foo: 'bar' });
+file.foo === 'bar'; // true
+```
+
+### Instance methods
+
+Each Vinyl object will have instance methods. Every method will be available but may return differently based on what properties were set upon instantiation or modified since.
+
+#### `file.isBuffer()`
+
+Returns `true` if the file contents are a [`Buffer`][buffer], otherwise `false`.
+
+#### `file.isStream()`
+
+Returns `true` if the file contents are a [`Stream`][stream], otherwise `false`.
+
+#### `file.isNull()`
+
+Returns `true` if the file contents are `null`, otherwise `false`.
+
+#### `file.isDirectory()`
+
+Returns `true` if the file represents a directory, otherwise `false`.
+
+A file is considered a directory when:
+
+- `file.isNull()` is `true`
+- `file.stat` is an object
+- `file.stat.isDirectory()` returns `true`
+
+When constructing a Vinyl object, pass in a valid [`fs.Stats`][fs-stats] object via `options.stat`. If you are mocking the [`fs.Stats`][fs-stats] object, you may need to stub the `isDirectory()` method.
+
+#### `file.isSymbolic()`
+
+Returns `true` if the file represents a symbolic link, otherwise `false`.
+
+A file is considered symbolic when:
+
+- `file.isNull()` is `true`
+- `file.stat` is an object
+- `file.stat.isSymbolicLink()` returns `true`
+
+When constructing a Vinyl object, pass in a valid [`fs.Stats`][fs-stats] object via `options.stat`. If you are mocking the [`fs.Stats`][fs-stats] object, you may need to stub the `isSymbolicLink()` method.
+
+#### `file.clone([options])`
+
+Returns a new Vinyl object with all attributes cloned.
+
+__By default custom attributes are cloned deeply.__
+
+If `options` or `options.deep` is `false`, custom attributes will not be cloned deeply.
+
+If `file.contents` is a [`Buffer`][buffer] and `options.contents` is `false`, the [`Buffer`][buffer] reference will be reused instead of copied.
+
+#### `file.inspect()`
+
+Returns a formatted-string interpretation of the Vinyl object. Automatically called by node's `console.log`.
+
+### Instance properties
+
+Each Vinyl object will have instance properties. Some may be unavailable based on what properties were set upon instantiation or modified since.
+
+#### `file.contents`
+
+Gets and sets the contents of the file. If set to a [`ReadableStream`][readable-stream], it is wrapped in a [`cloneable-readable`][cloneable-readable] stream.
+
+Throws when set to any value other than a [`ReadableStream`][readable-stream], a [`Buffer`][buffer] or `null`.
+
+Type: [`ReadableStream`][readable-stream], [`Buffer`][buffer], or `null`
+
+#### `file.cwd`
+
+Gets and sets current working directory. Will always be normalized and have trailing separators removed.
+
+Throws when set to any value other than non-empty strings.
+
+Type: `String`
+
+#### `file.base`
+
+Gets and sets base directory. Used for relative pathing (typically where a glob starts).
+When `null` or `undefined`, it simply proxies the `file.cwd` property. Will always be normalized and have trailing separators removed.
+
+Throws when set to any value other than non-empty strings or `null`/`undefined`.
+
+Type: `String`
+
+#### `file.path`
+
+Gets and sets the absolute pathname string or `undefined`. Setting to a different value appends the new path to `file.history`. If set to the same value as the current path, it is ignored. All new values are normalized and have trailing separators removed.
+
+Throws when set to any value other than a string.
+
+Type: `String`
+
+#### `file.history`
+
+Array of `file.path` values the Vinyl object has had, from `file.history[0]` (original) through `file.history[file.history.length - 1]` (current). `file.history` and its elements should normally be treated as read-only and only altered indirectly by setting `file.path`.
+
+Type: `Array`
+
+#### `file.relative`
+
+Gets the result of `path.relative(file.base, file.path)`.
+
+Throws when set or when `file.path` is not set.
+
+Type: `String`
+
+Example:
+
+```js
+var file = new File({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js'
+});
+
+console.log(file.relative); // file.js
+```
+
+#### `file.dirname`
+
+Gets and sets the dirname of `file.path`. Will always be normalized and have trailing separators removed.
+
+Throws when `file.path` is not set.
+
+Type: `String`
+
+Example:
+
+```js
+var file = new File({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js'
+});
+
+console.log(file.dirname); // /test
+
+file.dirname = '/specs';
+
+console.log(file.dirname); // /specs
+console.log(file.path); // /specs/file.js
+```
+
+#### `file.basename`
+
+Gets and sets the basename of `file.path`.
+
+Throws when `file.path` is not set.
+
+Type: `String`
+
+Example:
+
+```js
+var file = new File({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js'
+});
+
+console.log(file.basename); // file.js
+
+file.basename = 'file.txt';
+
+console.log(file.basename); // file.txt
+console.log(file.path); // /test/file.txt
+```
+
+#### `file.stem`
+
+Gets and sets stem (filename without suffix) of `file.path`.
+
+Throws when `file.path` is not set.
+
+Type: `String`
+
+Example:
+
+```js
+var file = new File({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js'
+});
+
+console.log(file.stem); // file
+
+file.stem = 'foo';
+
+console.log(file.stem); // foo
+console.log(file.path); // /test/foo.js
+```
+
+#### `file.extname`
+
+Gets and sets extname of `file.path`.
+
+Throws when `file.path` is not set.
+
+Type: `String`
+
+Example:
+
+```js
+var file = new File({
+  cwd: '/',
+  base: '/test/',
+  path: '/test/file.js'
+});
+
+console.log(file.extname); // .js
+
+file.extname = '.txt';
+
+console.log(file.extname); // .txt
+console.log(file.path); // /test/file.txt
+```
+
+#### `file.symlink`
+
+Gets and sets the path where the file points to if it's a symbolic link. Will always be normalized and have trailing separators removed.
+
+Throws when set to any value other than a string.
+
+Type: `String`
+
+### `Vinyl.isVinyl(file)`
+
+Static method used for checking if an object is a Vinyl file. Use this method instead of `instanceof`.
+
+Takes an object and returns `true` if it is a Vinyl file, otherwise returns `false`.
+
+__Note: This method uses an internal flag that some older versions of Vinyl didn't expose.__
+
+Example:
+
+```js
+var Vinyl = require('vinyl');
+
+var file = new Vinyl();
+var notAFile = {};
+
+Vinyl.isVinyl(file); // true
+Vinyl.isVinyl(notAFile); // false
+```
+
+### `Vinyl.isCustomProp(property)`
+
+Static method used by Vinyl when setting values inside the constructor or when copying properties in `file.clone()`.
+
+Takes a string `property` and returns `true` if the property is not used internally, otherwise returns `false`.
+
+This method is useful for inheritting from the Vinyl constructor. Read more in [Extending Vinyl][extending-vinyl].
+
+Example:
+
+```js
+var Vinyl = require('vinyl');
+
+Vinyl.isCustomProp('sourceMap'); // true
+Vinyl.isCustomProp('path'); // false -> internal getter/setter
+```
+
+## Normalization and concatenation
+
+Since all properties are normalized in their setters, you can just concatenate with `/`, and normalization takes care of it properly on all platforms.
+
+Example:
+
+```js
+var file = new File();
+file.path = '/' + 'test' + '/' + 'foo.bar';
+
+console.log(file.path);
+// posix => /test/foo.bar
+// win32 => \\test\\foo.bar
+```
+
+But never concatenate with `\`, since that is a valid filename character on posix system.
+
+## Extending Vinyl
+
+When extending Vinyl into your own class with extra features, you need to think about a few things.
+
+When you have your own properties that are managed internally, you need to extend the static `isCustomProp` method to return `false` when one of these properties is queried.
+
+```js
+var Vinyl = require('vinyl');
+
+var builtInProps = ['foo', '_foo'];
+
+class SuperFile extends Vinyl {
+  constructor(options) {
+    super(options);
+    this._foo = 'example internal read-only value';
+  }
+
+  get foo() {
+    return this._foo;
+  }
+
+  static isCustomProp(name) {
+    return super.isCustomProp(name) && builtInProps.indexOf(name) === -1;
+  }
+}
+```
+
+This makes properties `foo` and `_foo` ignored when cloning, and when passed in options to `constructor(options)` so they don't get assigned to the new object.
+
+Same goes for `clone()`. If you have your own internal stuff that needs special handling during cloning, you should extend it to do so.

+
+> base-methods plugin that adds a `config` method for mapping declarative configuration values to other 'base' methods or custom functions.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install base-config --save
+```
+
+## Usage
+
+```js
+var config = require('base-config');
+var base = require('base');
+var app = base();
+
+// register the plugin
+app.use(config());
+```
+
+## Mapped methods
+
+The following methods are mapped by default, but any of them can be [overridden](#map-custom-methods) using `app.config.map()`:
+
+* `.cwd`
+* `.data`
+* `.define`
+* `.del`
+* `.disable`
+* `.disabled`
+* `.enable`
+* `.enabled`
+* `.get`
+* `.has`
+* `.option`
+* `.set`
+* `.store`
+* `.use`
+
+## Map custom methods
+
+> Map properties on a configuration object to methods on `app`.
+
+Each key on the given object should match the name of a method on `app`.
+
+```js
+// call `config` as a function
+app.config({
+  set: function(val) {
+    app.set(val);
+  }
+});
+// or use the `map` method
+app.config
+  .map('set')
+  .map('get')
+  .map('has');
+```
+
+## Process
+
+Iterate over each property on the given object or array of objects, and call the mapped method that matches property key.
+
+```js
+//=> calls `app.set('foo', 'bar');
+app.config.process({set: {foo: 'bar'}}, function(err) {
+  if (err) throw err;
+});
+```
+
+## API
+
+### [create](index.js#L30)
+
+Create a function for mapping `app` properties onto the
+given `prop` namespace.
+
+**Params**
+
+* `prop` **{String}**: The namespace to use
+* `argv` **{Object}**
+* `returns` **{Object}**

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+Base plugin that adds a getter/setter for the current working directory.
+
+## Table of Contents
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-cwd
+```
+
+## Usage
+
+```js
+var cwd = require('base-cwd');
+var Base = require('base');
+var app = new Base();
+app.use(cwd());
+```
+
+Adds a `cwd` getter/setter to `app`:
+
+```js
+console.log(app.cwd);
+//=> /Users/jonschlinkert/dev/base/base-cwd
+console.log(app.cwd === process.cwd());
+//=> true
+```
+
+If `app.options.cwd` is defined it will used by `app.cwd`:
+
+```js
+app.options.cwd = 'foo/bar';
+console.log(app.cwd);
+//=> /Users/jonschlinkert/dev/base/base-cwd/foo/bar
+console.log(app.cwd === process.cwd());
+//=> false
+```
+
+If `app.cwd` is set, it will also set the value to `app.cache.cwd`, to ensure that the user-defined value is used on the next _get_.

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-data
+```
+
+## Usage
+
+Adds a `data` method to [base](https://github.com/node-base/base) that can be used for setting, getting and loading data onto a specified object in your application.
+
+```js
+var Base = require('base');
+var data = require('base-data');
+
+// instantiate `Base`
+var base = new Base();
+// add `data` as a plugin
+base.use(data());
+```
+
+**Examples**
+
+Add data:
+
+```js
+app.data('a', 'b');
+app.data({c: 'd'});
+app.data('e', ['f']);
+console.log(app.cache.data);
+//=> {a: 'b', c: 'd', e: ['f']}
+```
+
+**cache.data**
+
+By default, all data is loaded onto `app.cache.data`. This can be customized by passing the property to use when the plugin is initialized.
+
+For example, the following set `app.foo` as object for storing data:
+
+```js
+app.use(data('foo'));
+app.data('a', 'b');
+console.log(app.foo);
+//=> {a: 'b'}
+```
+
+## API
+
+### [.dataLoader](index.js#L66)
+
+Register a data loader for loading data onto `app.cache.data`.
+
+**Params**
+
+* `ext` **{String}**: The file extension for to match to the loader
+* `fn` **{Function}**: The loader function.
+
+**Example**
+
+```js
+var yaml = require('js-yaml');
+
+app.dataLoader('yml', function(str, fp) {
+  return yaml.safeLoad(str);
+});
+
+app.data('foo.yml');
+//=> loads and parses `foo.yml` as yaml
+```
+
+### [.data](index.js#L101)
+
+Load data onto `app.cache.data`
+
+**Params**
+
+* `key` **{String|Object}**: Key of the value to set, or object to extend.
+* `val` **{any}**
+* `returns` **{Object}**: Returns the instance of `Template` for chaining
+
+**Example**
+
+```js
+console.log(app.cache.data);
+//=> {};
+
+app.data('a', 'b');
+app.data({c: 'd'});
+console.log(app.cache.data);
+//=> {a: 'b', c: 'd'}
+
+// set an array
+app.data('e', ['f']);
+
+// overwrite the array
+app.data('e', ['g']);
+
+// update the array
+app.data('e', ['h'], true);
+console.log(app.cache.data.e);
+//=> ['g', 'h']
+```
+
+### [.data.extend](index.js#L252)
+
+Shallow extend an object onto `app.cache.data`.
+
+**Params**
+
+* `key` **{String|Object}**: Property name or object to extend onto `app.cache.data`. Dot-notation may be used for extending nested properties.
+* `value` **{Object}**: The object to extend onto `app.cache.data`
+* `returns` **{Object}**: returns the instance for chaining
+
+**Example**
+
+```js
+app.data({a: {b: {c: 'd'}}});
+app.data.extend('a.b', {x: 'y'});
+console.log(app.get('a.b'));
+//=> {c: 'd', x: 'y'}
+```
+
+### [.data.merge](index.js#L285)
+
+Deeply merge an object onto `app.cache.data`.
+
+**Params**
+
+* `key` **{String|Object}**: Property name or object to merge onto `app.cache.data`. Dot-notation may be used for merging nested properties.
+* `value` **{Object}**: The object to merge onto `app.cache.data`
+* `returns` **{Object}**: returns the instance for chaining
+
+**Example**
+
+```js
+app.data({a: {b: {c: {d: {e: 'f'}}}}});
+app.data.merge('a.b', {c: {d: {g: 'h'}}});
+console.log(app.get('a.b'));
+//=> {c: {d: {e: 'f', g: 'h'}}}
+```
+
+### [.data.union](index.js#L317)
+
+Union the given value onto a new or existing array value on `app.cache.data`.
+
+**Params**
+
+* `key` **{String}**: Property name. Dot-notation may be used for nested properties.
+* `array` **{Object}**: The array to add or union on `app.cache.data`
+* `returns` **{Object}**: returns the instance for chaining
+
+**Example**
+
+```js
+app.data({a: {b: ['c', 'd']}});
+app.data.union('a.b', ['e', 'f']}});
+console.log(app.get('a.b'));
+//=> ['c', 'd', 'e', 'f']
+```
+
+### [.data.set](index.js#L337)
+
+Set the given value onto `app.cache.data`.
+
+**Params**
+
+* `key` **{String|Object}**: Property name or object to merge onto `app.cache.data`. Dot-notation may be used for nested properties.
+* `val` **{any}**: The value to set on `app.cache.data`
+* `returns` **{Object}**: returns the instance for chaining
+
+**Example**
+
+```js
+app.data.set('a.b', ['c', 'd']}});
+console.log(app.get('a'));
+//=> {b: ['c', 'd']}
+```
+
+### [.data.get](index.js#L360)
+
+Get the value of `key` from `app.cache.data`. Dot-notation may be used for getting nested properties.
+
+**Params**
+
+* `key` **{String}**: The name of the property to get.
+* `returns` **{any}**: Returns the value of `key`
+
+**Example**
+
+```js
+app.data({a: {b: {c: 'd'}}});
+console.log(app.get('a.b'));
+//=> {c: 'd'}
+```
+
+## Glob patterns
+
+Glob patterns may be passed as a string or array. All of these work:
+
+```js
+app.data('foo.json');
+app.data('*.json');
+app.data(['*.json']);
+// pass options to node-glob
+app.data(['*.json'], {dot: true});
+```
+
+## Namespacing
+
+Namespacing allows you to load data onto a specific key, optionally using part of the file path as the key.
+
+**Example**
+
+Given that `foo.json` contains `{a: 'b'}`:
+
+```js
+app.data('foo.json');
+console.log(app.cache.data);
+//=> {a: 'b'}
+
+app.data('foo.json', {namespace: true});
+console.log(app.cache.data);
+//=> {foo: {a: 'b'}}
+
+app.data('foo.json', {
+  namespace: function(fp) {
+    return path.basename(fp);
+  }
+});
+console.log(app.cache.data);
+//=> {'foo.json': {a: 'b'}}
+```
+
+## History
+
+**v0.6.0**
+
+* removes `renameKey` option for namespacing
+* replaces [is-valid-instance](https://github.com/jonschlinkert/is-valid-instance) and [is-registered](https://github.com/jonschlinkert/is-registered) with [is-valid-app](https://github.com/node-base/is-valid-app)
+
+**v0.5.0**
+
+* uses [is-valid-instance](https://github.com/jonschlinkert/is-valid-instance) and [is-registered](https://github.com/jonschlinkert/is-registered) to ensure the smart plugin is registered on the correct objects.
+
+**v0.4.0**
+
+* _Refactored_
+
+* adds methods to `.data` for getting and setting data.
+
+**v0.3.6**
+
+* adds a basic loader that only calls the `JSON.parse` method, if no other loaders are defined
+* calls `.isRegistered` from [base](https://github.com/node-base/base) to ensure the plugin is only loaded once on an instance

+
+> Returns `true` if an array has a glob pattern.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-glob
+```
+
+## Usage
+
+```js
+var hasGlob = require('has-glob');
+
+hasGlob(['foo', 'bar', '*.js']);
+//=> true
+
+hasGlob(['foo', 'bar', 'baz']);
+//=> false
+```
+
+**True**
+
+The following all return `true`:
+
+```js
+hasGlob(['foo', 'bar', '*.js'])
+hasGlob(['foo', 'bar', '!*.js'])
+hasGlob(['foo', 'bar', '!foo'])
+hasGlob(['foo', 'bar', '!foo.js'])
+hasGlob(['foo', 'bar', '**/abc.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/{a,b}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z..2}.js'])
+hasGlob(['foo', 'bar', 'abc/@(a).js'])
+hasGlob(['foo', 'bar', 'abc/!(a).js'])
+hasGlob(['foo', 'bar', 'abc/+(a).js'])
+hasGlob(['foo', 'bar', 'abc/*(a).js'])
+hasGlob(['foo', 'bar', 'abc/?(a).js'])
+hasGlob(['foo', 'bar', 'abc/@.js'])
+hasGlob(['foo', 'bar', 'abc/!.js'])
+hasGlob(['foo', 'bar', 'abc/+.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', 'abc/(aaa|bbb).js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', '?.js'])
+hasGlob(['foo', 'bar', '[abc].js'])
+hasGlob(['foo', 'bar', '[^abc].js'])
+hasGlob(['foo', 'bar', 'a/b/c/[a-z].js'])
+hasGlob(['foo', 'bar', '[a-j]*[^c]b/c'])
+//=> true
+```
+
+Also works with strings:
+
+```js
+hasGlob('*.js')
+hasGlob('!*.js')
+hasGlob('!foo')
+hasGlob('!foo.js')
+hasGlob('**/abc.js')
+hasGlob('abc/*.js')
+//=> true
+```
+
+**False**
+
+The following all return `false`:
+
+```js
+hasGlob([])
+hasGlob([null])
+hasGlob([undefined])
+hasGlob([{}])
+hasGlob(['.'])
+hasGlob(['foo', 'bar', 'aa'])
+hasGlob(['foo', 'bar', 'abc.js'])
+hasGlob(['foo', 'bar', 'abc/def/ghi.js'])
+//=> false
+```

+
+> Returns true if a value exists, false if empty. Works with deeply nested values using object paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-value
+```
+
+**Works for:**
+
+* booleans
+* functions
+* numbers
+* strings
+* nulls
+* object
+* arrays
+
+## Usage
+
+Works with property values (supports object-path notation, like `foo.bar`) or a single value:
+
+```js
+var hasValue = require('has-value');
+
+hasValue('foo');
+hasValue({foo: 'bar'}, 'foo');
+hasValue({a: {b: {c: 'foo'}}}, 'a.b.c');
+//=> true
+
+hasValue('');
+hasValue({foo: ''}, 'foo');
+//=> false
+
+hasValue(0);
+hasValue(1);
+hasValue({foo: 0}, 'foo');
+hasValue({foo: 1}, 'foo');
+hasValue({foo: null}, 'foo');
+hasValue({foo: {bar: 'a'}}}, 'foo');
+hasValue({foo: {bar: 'a'}}}, 'foo.bar');
+//=> true
+
+hasValue({foo: {}}}, 'foo');
+hasValue({foo: {bar: {}}}}, 'foo.bar');
+hasValue({foo: undefined}, 'foo');
+//=> false
+
+hasValue([]);
+hasValue([[]]);
+hasValue([[], []]);
+hasValue([undefined]);
+hasValue({foo: []}, 'foo');
+//=> false
+
+hasValue([0]);
+hasValue([null]);
+hasValue(['foo']);
+hasValue({foo: ['a']}, 'foo');
+//=> true
+
+hasValue(function() {})
+hasValue(function(foo) {})
+hasValue({foo: function(foo) {}}, 'foo'); 
+hasValue({foo: function() {}}, 'foo');
+//=> true
+
+hasValue(true);
+hasValue(false);
+hasValue({foo: true}, 'foo');
+hasValue({foo: false}, 'foo');
+//=> true
+```
+
+## isEmpty
+
+To do the opposite and test for empty values, do:
+
+```js
+function isEmpty(o) {
+  return !hasValue.apply(hasValue, arguments);
+}
+```
+
+## Release history
+
+### v1.0.0
+
+* `zero` always returns true
+* `array` now recurses, so that an array of empty arrays will return `false`
+* `null` now returns true

+> Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```
+
+Visit [base](https://github.com/node-base/base) for more details.
+
+## History
+
+**v0.3.0**
+
+* upgrades [is-valid-instance](https://github.com/jonschlinkert/is-valid-instance) to v0.3.0, which adds support for checking `app.type` for the instance type. We don't expect any regressions, but if you experience one, please [create an issue](../../issues/new).

+
+> Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-instance
+```
+
+## Usage
+
+Use in your [base](https://github.com/node-base/base) plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates](https://github.com/jonschlinkert/templates) view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates](https://github.com/jonschlinkert/templates) view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+# set-value [![NPM version](https://img.shields.io/npm/v/set-value.svg?style=flat)](https://www.npmjs.com/package/set-value) [![NPM monthly downloads](https://img.shields.io/npm/dm/set-value.svg?style=flat)](https://npmjs.org/package/set-value) [![NPM total downloads](https://img.shields.io/npm/dt/set-value.svg?style=flat)](https://npmjs.org/package/set-value) [![Linux Build Status](https://img.shields.io/travis/jonschlinkert/set-value.svg?style=flat&label=Travis)](https://travis-ci.org/jonschlinkert/set-value)
+
+> Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save set-value
+```
+
+## Usage
+
+```js
+var set = require('set-value');
+set(object, prop, value);
+```
+
+### Params
+
+* `object` **{object}**: The object to set `value` on
+* `prop` **{string}**: The property to set. Dot-notation may be used.
+* `value` **{any}**: The value to set on `object[prop]`
+
+## Examples
+
+Updates and returns the given object:
+
+```js
+var obj = {};
+set(obj, 'a.b.c', 'd');
+console.log(obj);
+//=> { a: { b: { c: 'd' } } }
+```
+
+### Escaping
+
+**Escaping with backslashes**
+
+Prevent set-value from splitting on a dot by prefixing it with backslashes:
+
+```js
+console.log(set({}, 'a\\.b.c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, 'a\\.b\\.c', 'd'));
+//=> { 'a.b.c': 'd' }
+```
+
+**Escaping with double-quotes or single-quotes**
+
+Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:
+
+```js
+console.log(set({}, '"a.b".c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, "'a.b'.c", "d"));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, '"this/is/a/.file.path"', 'd'));
+//=> { 'this/is/a/file.path': 'd' }
+```
+
+### Bracket support
+
+set-value does not split inside brackets or braces:
+
+```js
+console.log(set({}, '[a.b].c', 'd'));
+//=> { '[a.b]': { c: 'd' } }
+
+console.log(set({}, "(a.b).c", "d"));
+//=> { '(a.b)': { c: 'd' } }
+
+console.log(set({}, "<a.b>.c", "d"));
+//=> { '<a.b>': { c: 'd' } }
+
+console.log(set({}, "{a..b}.c", "d"));
+//=> { '{a..b}': { c: 'd' } }
+```
+
+## History
+
+### v2.0.0
+
+* Adds support for escaping with double or single quotes. See [escaping](#escaping) for examples.
+* Will no longer split inside brackets or braces. See [bracket support](#bracket-support) for examples.
+
+If there are any regressions please create a [bug report](../../issues/new). Thanks!

+
+> Adds support for managing template engines to your base application.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-engines
+```
+
+## Usage
+
+Register the plugin with your [base](https://github.com/node-base/base) application:
+
+```js
+var Base = require('base');
+var engines = require('base-engines');
+base.use(engines());
+```
+
+## API
+
+### [.engine](index.js#L45)
+
+Register a view engine callback `fn` as `ext`. Calls `.setEngine` and `.getEngine` internally.
+
+**Params**
+
+* `exts` **{String|Array}**: String or array of file extensions.
+* `fn` **{Function|Object}**: or `settings`
+* `settings` **{Object}**: Optionally pass engine options as the last argument.
+
+**Example**
+
+```js
+app.engine('hbs', require('engine-handlebars'));
+
+// using consolidate.js
+var engine = require('consolidate');
+app.engine('jade', engine.jade);
+app.engine('swig', engine.swig);
+
+// get a registered engine
+var swig = app.engine('swig');
+```
+
+### [.setEngine](index.js#L74)
+
+Register engine `ext` with the given render `fn` and/or `settings`.
+
+**Params**
+
+* `ext` **{String}**: The engine to set.
+
+**Example**
+
+```js
+app.setEngine('hbs', require('engine-handlebars'), {
+  delims: ['<%', '%>']
+});
+```
+
+### [.getEngine](index.js#L97)
+
+Get registered engine `ext`.
+
+**Params**
+
+* `ext` **{String}**: The engine to get.
+
+**Example**
+
+```js
+app.engine('hbs', require('engine-handlebars'));
+var engine = app.getEngine('hbs');
+```

+# is-valid-instance [![NPM version](https://img.shields.io/npm/v/is-valid-instance.svg?style=flat)](https://www.npmjs.com/package/is-valid-instance) [![NPM downloads](https://img.shields.io/npm/dm/is-valid-instance.svg?style=flat)](https://npmjs.org/package/is-valid-instance) [![Build Status](https://img.shields.io/travis/jonschlinkert/is-valid-instance.svg?style=flat)](https://travis-ci.org/jonschlinkert/is-valid-instance)
+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+> Base plugin, creates a normalized environment object from a function, filepath or instance of base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-env
+```
+
+## Usage
+
+```js
+var Base = require('base');
+var env = require('base-env');
+var base = new Base();
+base.use(env());
+```
+
+## API
+
+### [createEnv](index.js#L42)
+
+Create an `env` object with the given `name`, function, filepath or app instance, and options. See the [Env](#Env) API docs below.
+
+**Params**
+
+* `name` **{String}**
+* `val` **{Object|Function|String}**
+* `options` **{Object}**
+* `returns` **{Object}**
+
+**Example**
+
+```js
+var base = require('base');
+var env = require('base-env');
+var app = new Base();
+app.use(env());
+
+var env = app.createEnv('foo', function() {});
+```
+
+### [Env](lib/env.js#L33)
+
+Create an instance of `Env` with the given `name`, `fn`, `app` instance, and options. The `Env` class is used by [base-generators][] to handle some of the heavy lifting for resolving generators.
+
+**Params**
+
+* `name` **{String}**
+* `fn` **{Function|Object|String}**: Function to be lazily invoked, instance, or filepath that resolves to one of the other types when required.
+* `app` **{Object}**: Base instance to use for invocation context.
+* `options` **{Object}**
+
+**Example**
+
+```js
+var env = new Env('foo', function(app) {
+  // do stuff to app
+});
+```
+
+### [.isMatch](lib/env.js#L67)
+
+Returns true if the given `str` matches any of the following properties, in order:
+
+* `env.key`
+* `env.name`
+* `env.alias`
+* `env.dirname`
+* `env.path`
+* `env.basename`
+
+**Params**
+
+* `str` **{String}**: The string to match
+* `returns` **{Boolean}**: Retuns true if a match is made.
+
+**Example**
+
+```js
+var env = new Env('foo', fucntion(){});
+console.log(env.isMatch('bar')) //=> false
+console.log(env.isMatch('foo')) //=> true
+```
+
+### [.invoke](lib/env.js#L97)
+
+Invoke `env.fn` with the given `context` and `options`.
+
+**Params**
+
+* `context` **{Object}**: The application instance to use for invoking `env.fn`
+* `opptions` **{Object}**
+* `returns` **{Object}**
+
+**Example**
+
+```js
+var app = new Base();
+env.fn(app, {doStuff: true});
+```
+
+### [.isDefault](lib/env.js#L165)
+
+Getter that is set to `true` when the env being loaded is in the user's working directory.
+
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+var env = new Env('generator.js', generatorFn, {cwd: process.cwd()});
+console.log(env.isDefault);
+//=> true
+```
+
+### [.namespace](lib/env.js#L185)
+
+Getter for resolving the `namespace` of an `env`. A namespace is created by joining the `namespace` from a parent instance (if exists) to `env.alias` (e.g. `parent.namespace + '.' + env.alias`).
+
+```js
+var env = new Env('foo', function() {});
+
+* `returns` **{String}**

+
+Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-generators
+```
+
+**HEADS UP!**
+
+The `.generateEach` method has been deprecated. Use `.generate` instead.
+
+## Usage
+
+```js
+var generators = require('base-generators');
+var Base = require('base');
+
+// register the plugin before instantiating, to make 
+// sure the plugin is called on all Generator instances 
+Base.use(generators());
+var base = new Base();
+```
+
+## Examples
+
+All examples assume the following code is defined:
+
+```js
+var Base = require('base');
+var generators = require('base-generators');
+
+Base.use(generators());
+var base = new Base();
+```
+
+### Tasks
+
+Tasks are exactly the same as [gulp](http://gulpjs.com) tasks, and are powered by [bach](https://github.com/gulpjs/bach) and [composer](https://github.com/doowb/composer).
+
+**Register a task:**
+
+```js
+base.task('default', function(cb) {
+  // do stuff
+  cb();
+});
+```
+
+**Run a task:**
+
+```js
+base.build('default', function(err) {
+  if (err) throw err;
+});
+```
+
+### Generators
+
+> I heard you liked tasks, so I put some tasks in your tasks.
+
+**What's a generator?**
+
+Generators are functions that are registered by name, and are used to encapsulate and organize code, [tasks](#tasks), other generators, or [sub-generators](#sub-generators), in a sharable, publishable and easily re-usable way.
+
+In case it helps, here are some [live examples](#in-the-wild).
+
+**Register a generator:**
+
+```js
+base.register('foo', function(app, base) {
+  // `app` is the generator's "private" instance
+  // `base` is a "shared" instance, accessible by all generators
+});
+```
+
+**Get a generator:**
+
+```js
+var foo = base.generator('foo');
+```
+
+**Register tasks in a generator:**
+
+```js
+base.register('foo', function(app, base) {
+  app.task('default', function() {});
+  app.task('one', function() {});
+  app.task('two', function() {});
+});
+```
+
+**Run a generator's tasks:**
+
+The `.generate` method simply calls the `.build` method on a specific generator.
+
+To run a generator's tasks, pass the generator name as the first argument, and optionally define one or more tasks as the second argument. _(If no tasks are defined, the `default` task is run.)_
+
+```js
+// run the "default" task on generator "foo"
+base.generate('foo', function(err) {
+  if (err) throw err;
+  console.log('done!');
+});
+
+// or specify tasks
+base.generate('foo', ['default'], function() {});
+base.generate('foo', ['one', 'two'], function() {});
+```
+
+Alternatively, you can call `.build` on the generator directly:
+
+```js
+// run the "default" task on generator "foo"
+base.generator('foo')
+  .build('default', function(err) {
+    if (err) throw err;
+  });
+```
+
+### Sub-generators
+
+Sub-generators are just generators that are registered on (or invoked within) another generator instance.
+
+**Register sub-generators:**
+
+Register generators `one`, `two`, and `three` on generator `foo`:
+
+```js
+base.register('foo', function(app, base) {
+  app.register('one', function() {});
+  app.register('two', function() {});
+  app.register('three', function() {});
+});
+```
+
+**Get a sub-generator:**
+
+Use dot-notation to get a sub-generator:
+
+```js
+var one = base.generator('foo.one');
+```
+
+Sub-generators may be nested to any level. In reality, you probably won't write code like the following example, but this only illustrates the point that generators are extremely composable, and can be built on top of or with other generators.
+
+```js
+base.register('a', function(a, base) {
+  // do stuff
+  a.register('b', function(b) {
+    // do stuff
+    b.register('c', function(c) {
+      // do stuff
+      c.register('d', function(d) {
+        // do stuff
+        d.register('e', function(e) {
+          // arbitrary task
+          e.task('default', function(cb) {
+            console.log('e > default!');
+            cb();
+          });
+        });
+      });
+    });
+  });
+});
+
+base.getGenerator('a.b.c.d.e')
+  .build(function(err) {
+    if (err) throw err;
+    // 'e > default!'
+  });
+```
+
+**Register tasks on sub-generators:**
+
+```js
+base.register('foo', function(app, base) {
+  app.register('one', function(one) {
+    one.task('default', function() {});
+    one.task('a', function() {});
+    one.task('b', function() {});
+    one.task('c', function() {});
+  });
+
+  app.register('two', function(two) {
+    two.task('default', function() {});
+  });
+
+  app.register('three', function(three) {
+    three.task('default', function() {});
+  });
+});
+```
+
+**Run a sub-generator's tasks**
+
+```js
+// run the `default` task from sub-generator `foo.one`
+base.generate('foo.one', function(err) {
+  if (err) throw err;
+  console.log('done!');
+});
+```
+
+**Run multiple tasks on a sub-generator:**
+
+```js
+// run tasks `a`, `b` and `c` on sub-generator `foo.one`
+base.generate('foo.one', ['a', 'b', 'c'], function(err) {
+  if (err) throw err;
+  console.log('done!');
+});
+```
+
+## In the wild
+
+The following applications use this library:
+
+* [generate](https://github.com/generate/generate): adds a CLI, template rendering, fs methods and generator convenience-methods to base-generators
+* [assemble](https://github.com/assemble/assemble): site generation
+* [verb](https://github.com/verbose/verb): documentation generation
+* [update](https://github.com/update/update): renames generators to "updaters", which are used to keep your project up-to-date
+
+## API
+
+### [.register](index.js#L60)
+
+Alias to `.setGenerator`.
+
+**Example**
+
+```js
+app.register('foo', function(app, base) {
+  // "app" is a private instance created for the generator
+  // "base" is a shared instance
+});
+```
+
+**Params**
+
+* `name` **{String}**: The generator's name
+* `options` **{Object|Function|String}**: or generator
+* `generator` **{Object|Function|String}**: Generator function, instance or filepath.
+* `returns` **{Object}**: Returns the generator instance.
+
+### [.generator](index.js#L85)
+
+Get and invoke generator `name`, or register generator `name` with the given `val` and `options`, then invoke and return the generator instance. This method differs from `.register`, which lazily invokes generator functions when `.generate` is called.
+
+**Example**
+
+```js
+app.generator('foo', function(app, base, env, options) {
+  // "app" - private instance created for generator "foo"
+  // "base" - instance shared by all generators
+  // "env" - environment object for the generator
+  // "options" - options passed to the generator
+});
+```
+
+**Params**
+
+* `name` **{String}**
+* `fn` **{Function|Object}**: Generator function, instance or filepath.
+* `returns` **{Object}**: Returns the generator instance or undefined if not resolved.
+
+### [.setGenerator](index.js#L116)
+
+Store a generator by file path or instance with the given `name` and `options`.
+
+**Example**
+
+```js
+app.setGenerator('foo', function(app, base) {
+  // "app" - private instance created for generator "foo"
+  // "base" - instance shared by all generators
+  // "env" - environment object for the generator
+  // "options" - options passed to the generator
+});
+```
+
+**Params**
+
+* `name` **{String}**: The generator's name
+* `options` **{Object|Function|String}**: or generator
+* `generator` **{Object|Function|String}**: Generator function, instance or filepath.
+* `returns` **{Object}**: Returns the generator instance.
+
+### [.getGenerator](index.js#L148)
+
+Get generator `name` from `app.generators`, same as [findGenerator], but also invokes the returned generator with the current instance. Dot-notation may be used for getting sub-generators.
+
+**Example**
+
+```js
+var foo = app.getGenerator('foo');
+
+// get a sub-generator
+var baz = app.getGenerator('foo.bar.baz');
+```
+
+**Params**
+
+* `name` **{String}**: Generator name.
+* `returns` **{Object|undefined}**: Returns the generator instance or undefined.
+
+### [.findGenerator](index.js#L179)
+
+Find generator `name`, by first searching the cache, then searching the cache of the `base` generator. Use this to get a generator without invoking it.
+
+**Example**
+
+```js
+// search by "alias"
+var foo = app.findGenerator('foo');
+
+// search by "full name"
+var foo = app.findGenerator('generate-foo');
+```
+
+**Params**
+
+* `name` **{String}**
+* `options` **{Function}**: Optionally supply a rename function on `options.toAlias`
+* `returns` **{Object|undefined}**: Returns the generator instance if found, or undefined.
+
+### [.getSubGenerator](index.js#L259)
+
+Get sub-generator `name`, optionally using dot-notation for nested generators.
+
+**Example**
+
+```js
+app.getSubGenerator('foo.bar.baz');
+```
+
+**Params**
+
+* `name` **{String}**: The property-path of the generator to get
+* `options` **{Object}**
+
+Iterate over `app.generators` and call `generator.isMatch(name)`
+on `name` until a match is found.
+
+**Params**
+
+* `name` **{String}**
+* `returns` **{Object|undefined}**: Returns a generator object if a match is found.
+
+**Example**
+
+```js
+console.log(app.hasGenerator('foo'));
+```
+
+**Params**
+
+* `name` **{String}**
+* `val` **{Object|Function}**
+* `returns` **{Boolean}**
+
+For example, if the lookup `name` is `foo`, the function might
+return `["generator-foo", "foo"]`, to ensure that the lookup happens
+in that order.
+
+**Params**
+
+* `name` **{String}**: Generator name to search for
+* `options` **{Object}**
+* `fn` **{Function}**: Lookup function that must return an array of names.
+* `returns` **{Object}**
+
+### [.extendWith](index.js#L384)
+
+Extend the generator instance with settings and features of another generator.
+
+**Example**
+
+```js
+var foo = base.generator('foo');
+app.extendWith(foo);
+// or
+app.extendWith('foo');
+// or
+app.extendWith(['foo', 'bar', 'baz']);
+
+app.extendWith(require('generate-defaults'));
+```
+
+**Params**
+
+* `app` **{String|Object}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+### [.toAlias](index.js#L554)
+
+Create a generator alias from the given `name`. By default the alias is the string after the last dash. Or the whole string if no dash exists.
+
+**Example**
+
+```js
+var camelcase = require('camel-case');
+var alias = app.toAlias('foo-bar-baz');
+//=> 'baz'
+
+// custom `toAlias` function
+app.option('toAlias', function(name) {
+  return camelcase(name);
+});
+var alias = app.toAlias('foo-bar-baz');
+//=> 'fooBarBaz'
+```
+
+**Params**
+
+* `name` **{String}**
+* `options` **{Object}**
+* `returns` **{String}**: Returns the alias.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+//=> {"name": "my-project", ...}
+```
+
+## API
+
+Visit [pkg-store](https://github.com/jonschlinkert/pkg-store) for additional API details and documentation.
+
+```js
+var pkg = require('base-pkg');
+var Base = require('base');
+var app = new Base();
+```
+
+### .pkg.set
+
+```js
+app.pkg.set(key, value);
+```
+
+Set property `key` with the given `value`.
+
+**Example**
+
+```js
+// given {"name": "my-project"}
+app.pkg.set('bin.foo', 'bar');
+
+console.log(app.pkg.data);
+//=> {"name": "my-project", "bin": {"foo": "bar"}}
+```
+
+### .pkg.save
+
+Persist package.json to the file system at `app.pkg.path`.
+
+```js
+app.pkg.save();
+```
+
+### .pkg.get
+
+```js
+app.pkg.get(key);
+```
+
+Get property `key` from package.json.
+
+**Example**
+
+```js
+// given {"name": "my-project"}
+app.pkg.set('bin.foo', 'bar');
+
+console.log(app.pkg.get('bin'));
+//=> {"foo": "bar"}
+```
+
+### .pkg.has
+
+```js
+app.pkg.has(key);
+```
+
+Returns `true` if `package.json` has property `key`.
+
+**Example**
+
+```js
+// given: {"name": "my-project"}
+console.log(app.pkg.has('name'));
+//=> true
+console.log(app.pkg.has('zzzzzzz'));
+//=> false
+```
+
+### .pkg.union
+
+```js
+app.pkg.union(key, val);
+```
+
+Create array `key`, or concatenate values to array `key`. Also uniquifies the array.
+
+**Example**
+
+```js
+app.pkg.union('keywords', 'foo');
+app.pkg.union('keywords', ['bar', 'baz']);
+
+console.log(app.pkg.get('keywords'));
+//=> ['foo', 'bar', 'baz']
+```
+
+## .pkg.expand
+
+Creates a get/set API using [cache-base](https://github.com/jonschlinkert/cache-base), where the cache is populated with a shallow clone of `package.json` with values expanded by [expand-pkg](https://github.com/jonschlinkert/expand-pkg).
+
+**Example**
+
+```js
+console.log(app.pkg.get('author'));
+//=> 'Jon Schlinkert (https://github.com/jonschlinkert)'
+
+var expanded = app.pkg.expand();
+var author = expanded.get('author');
+//=> {name: 'Jon Schlinkert', url: 'https://github.com/jonschlinkert'}
+```
+
+## Logging methods
+
+A handful of logging are exposed, as a convenience for implementors to log updates to package.json with visual consistency.
+
+### .pkg.logValue
+
+Log a value.
+
+```js
+app.pkg.logValue('current value is:', {reflinks: ['foo', 'bar']});
+```
+
+**Example**
+
+![logValue example](assets/log-value.jpg)
+
+### .pkg.logInfo
+
+Log an info message.
+
+```js
+app.pkg.logInfo('udpated value:', {reflinks: ['foo', 'bar']});
+```
+
+**Example**
+
+![logInfo example](assets/log-info.jpg)
+
+### .pkg.logWarning
+
+Log an warning message.
+
+```js
+app.pkg.logWarning('deleted value:', {reflinks: ['foo', 'bar']});
+```
+
+**Example**
+
+![logWarning example](assets/log-warning.jpg)
+
+### .pkg.logSuccess
+
+Log a success message.
+
+```js
+app.pkg.logSuccess('added value:', {reflinks: ['foo', 'bar']});
+```
+
+**Example**
+
+![logSuccess example](assets/log-success.jpg)
+
+### .pkg.logError
+
+Log an error message.
+
+```js
+app.pkg.logError('missing value:', {reflinks: ['foo', 'bar']});
+```
+
+**Example**
+
+![logError example](assets/log-error.jpg)

+> Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-accessor-descriptor
+```
+
+## Usage
+
+```js
+var isAccessor = require('is-accessor-descriptor');
+
+isAccessor({get: function() {}});
+//=> true
+```
+
+You may also pass an object and property name to check if the property is an accessor:
+
+```js
+isAccessor(foo, 'bar');
+```
+
+## Examples
+
+`false` when not an object
+
+```js
+isAccessor('a')
+isAccessor(null)
+isAccessor([])
+//=> false
+```
+
+`true` when the object has valid properties
+
+and the properties all have the correct JavaScript types:
+
+```js
+isAccessor({get: noop, set: noop})
+isAccessor({get: noop})
+isAccessor({set: noop})
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isAccessor({get: noop, set: noop, bar: 'baz'})
+isAccessor({get: noop, writable: true})
+isAccessor({get: noop, value: true})
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isAccessor({get: noop, set: 'baz'})
+isAccessor({get: 'foo', set: noop})
+isAccessor({get: 'foo', bar: 'baz'})

+
+> Returns true if a value has the characteristics of a valid JavaScript data descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-data-descriptor
+```
+
+## Usage
+
+```js
+var isDataDesc = require('is-data-descriptor');
+```
+
+## Examples
+
+`true` when the descriptor has valid properties with valid values.
+
+```js
+// `value` can be anything
+isDataDesc({value: 'foo'})
+isDataDesc({value: function() {}})
+isDataDesc({value: true})
+//=> true
+```
+
+`false` when not an object
+
+```js
+isDataDesc('a')
+//=> false
+isDataDesc(null)
+//=> false
+isDataDesc([])
+//=> false
+```
+
+`false` when the object has invalid properties
+
+```js
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', get: function(){}})
+//=> false
+isDataDesc({get: function(){}, value: 'foo'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDataDesc({value: 'foo', enumerable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', configurable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', writable: 'foo'})
+//=> false
+```
+
+## Valid properties
+
+The only valid data descriptor properties are the following:
+
+* `configurable` (required)
+* `enumerable` (required)
+* `value` (optional)
+* `writable` (optional)
+
+To be a valid data descriptor, either `value` or `writable` must be defined.
+
+**Invalid properties**
+
+A descriptor may have additional _invalid_ properties (an error will **not** be thrown).
+
+```js
+var foo = {};
+
+Object.defineProperty(foo, 'bar', {
+  enumerable: true,
+  whatever: 'blah', // invalid, but doesn't cause an error
+  get: function() {
+    return 'baz';
+  }
+});
+
+console.log(foo.bar);
+//=> 'baz'
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false
+isDescriptor({get: noop, configurable: 'foo'});
+//=> false
+```

+> Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```
+
+Visit [base](https://github.com/node-base/base) for more details.
+
+## History
+
+**v0.3.0**
+
+* upgrades [is-valid-instance](https://github.com/jonschlinkert/is-valid-instance) to v0.3.0, which adds support for checking `app.type` for the instance type. We don't expect any regressions, but if you experience one, please [create an issue](../../issues/new).

+
+> Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-instance
+```
+
+## Usage
+
+Use in your [base](https://github.com/node-base/base) plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates](https://github.com/jonschlinkert/templates) view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates](https://github.com/jonschlinkert/templates) view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'

+# lazy-cache [![NPM version](https://img.shields.io/npm/v/lazy-cache.svg)](https://www.npmjs.com/package/lazy-cache) [![Build Status](https://img.shields.io/travis/jonschlinkert/lazy-cache.svg)](https://travis-ci.org/jonschlinkert/lazy-cache)
+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+# base-store [![NPM version](https://img.shields.io/npm/v/base-store.svg?style=flat)](https://www.npmjs.com/package/base-store) [![NPM downloads](https://img.shields.io/npm/dm/base-store.svg?style=flat)](https://npmjs.org/package/base-store) [![Build Status](https://img.shields.io/travis/node-base/base-store.svg?style=flat)](https://travis-ci.org/node-base/base-store)
+
+Plugin for getting and persisting config values with your base-methods application. Adds a 'store' object that exposes all of the methods from the data-store library. Also now supports sub-stores!
+
+You might also be interested in [base-data](https://github.com/node-base/base-data).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install base-store --save
+```
+
+## Usage
+
+Adds `store` methods for doing things like this:
+
+```js
+app.store.set('a', 'z'); // DOES persist
+console.log(app.store.get('a'));
+//=> 'z';
+```
+
+## API
+
+Add a `.store` method to your [base](https://github.com/node-base/base) application:
+
+```js
+var store = require('base-store');
+var Base = require('base');
+var base = new Base();
+
+// store `name` is required
+base.use(store('foo'));
+
+// optionally define a cwd to use for persisting the store
+// default cwd is `~/data-store/`
+base.use(store('foo', {cwd: 'a/b/c'}));
+```
+
+**example usage**
+
+```js
+base.store
+  .set('a', 'b')
+  .set({c: 'd'})
+  .set('e.f', 'g')
+
+console.log(base.store.get('e.f'));
+//=> 'g'
+
+console.log(base.store.data);
+//=> {a: 'b', c: 'd', e: {f: 'g'}}
+```
+
+## Sub-stores
+
+A sub-store is a custom store that is persisted to its own file in a sub-folder of its "parent" store.
+
+**Create a sub-store**
+
+```js
+app.store.create('foo');
+// creates an instance of store on `app.store.foo`
+
+app.store.foo.set('a', 'b');
+app.store.foo.get('a');
+//=> 'b'
+```
+
+Sub-store data is also persisted to a property on the "parent" store:
+
+```js
+// set data on a sub-store
+app.store.foo.set('a', 'b');
+
+// get the value from parent store
+app.store.get('foo.a');
+//=> 'b'
+```
+
+### plugin params
+
+* `name` **{String}**: Store name.
+* `options` **{Object}**
+
+* `cwd` **{String}**: Current working directory for storage. If not defined, the user home directory is used, based on OS. This is the only option currently, other may be added in the future.
+* `indent` **{Number}**: Number passed to `JSON.stringify` when saving the data. Defaults to `2` if `null` or `undefined`
+
+## methods
+
+### .store.set
+
+Assign `value` to `key` and save to disk. Can be a key-value pair or an object.
+
+**Params**
+
+* `key` **{String}**
+* `val` **{any}**: The value to save to `key`. Must be a valid JSON type: String, Number, Array or Object.
+* `returns` **{Object}** `Store`: for chaining
+
+**Example**
+
+```js
+// key, value
+base.store.set('a', 'b');
+//=> {a: 'b'}
+
+// extend the store with an object
+base.store.set({a: 'b'});
+//=> {a: 'b'}
+
+// extend the the given value
+base.store.set('a', {b: 'c'});
+base.store.set('a', {d: 'e'}, true);
+//=> {a: {b 'c', d: 'e'}}
+
+// overwrite the the given value
+base.store.set('a', {b: 'c'});
+base.store.set('a', {d: 'e'});
+//=> {d: 'e'}
+```
+
+### .store.union
+
+Add or append an array of unique values to the given `key`.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{any}**: The array to add or append for `key`.
+
+**Example**
+
+```js
+base.store.union('a', ['a']);
+base.store.union('a', ['b']);
+base.store.union('a', ['c']);
+base.store.get('a');
+//=> ['a', 'b', 'c']
+```

+
+**Params**
+
+* `key` **{String}**
+* `returns` **{any}**: The value to store for `key`.
+
+**Example**
+
+```js
+base.store.set('a', {b: 'c'});

+
+base.store.get();
+//=> {b: 'c'}
+```
+

+Returns `true` if the specified `key` has truthy value.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{Boolean}**: Returns true if `key` has
+
+**Example**

+
+* `dest` **{String}**: Optionally define a different destination than the default path.
+
+**Example**
+
+```js
+base.store.save();
+```
+
+### .store.del
+
+Delete `keys` from the store, or delete the entire store if no keys are passed. A `del` event is also emitted for each key deleted.
+
+**Note that to delete the entire store you must pass `{force: true}`**
+
+**Params**
+
+* `keys` **{String|Array|Object}**: Keys to remove, or options.
+* `options` **{Object}**
+
+**Example**
+
+```js

+
+// to delete paths outside cwd
+base.store.del({force: true});
+```
+
+## History
+
+**v0.3.1**
+
+* Sub-stores are easier to create and get. You can now do `app.store.create('foo')` to create a sub-store, which is then available as `app.store.foo`.
+
+**v0.3.0**
+
+* Introducing sub-stores!

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+> base plugin that provides a very thin wrapper around [https://github.com/doowb/composer](https://github.com/doowb/composer) for adding task methods to your application.
+
+You might also be interested in [base-watch](https://github.com/node-base/base-watch).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base-task
+```
+
+## Usage
+
+```js
+var Base = require('base');
+var tasks = require('base-task');
+
+var base = new Base();
+// Since some applications have multiple types of plugins, you must 
+// set "isApp" on the instance you want base-task to run on 
+base.isApp = true;
+base.use(tasks());
+
+/**
+ * Define tasks
+ */
+
+base.task('foo', function(cb) {
+  console.log('this is foo!');
+  cb();
+});
+base.task('bar', function(cb) {
+  console.log('this is bar!');
+  cb();
+});
+
+/**
+ * Build tasks
+ */
+
+base.build(['foo', 'bar'], function(err) {
+  // this is foo!
+  // this is bar!
+  console.log('done!');
+});
+```
+
+See the [composer](https://github.com/jonschlinkert/composer) documentation for more details, or to create bug reports related to running or registering tasks.
+
+## API
+
+### .task
+
+Register a task
+
+**Params**
+
+* `name` **{String}**: Task name to register (tasks are cached on `app.tasks`)
+* `dependencies` **{String|Array|Function}**: String, list or array of tasks.
+* `callback` **{Function}**: Function to be called when the task is executed. Task functions should either return a stream or call the callback to let [composer](https://github.com/doowb/composer) know when the task is finished.
+
+**Examples**
+
+Register a task.
+
+```js
+app.task('default', function() {
+  // return the stream to signal "done"
+  return app.src('pages/*.hbs')
+    .pipe(app.dest('dist'));
+});
+```
+
+Register a task with dependencies (other tasks to run before executing the task):
+
+```js
+app.task('site', ['styles'], function() {
+  return app.src('pages/*.hbs')
+    .pipe(app.dest('dist'));
+});
+
+app.task('default', ['site']);
+```
+
+**Get a task**
+
+```js
+var task = app.task('site');
+```
+
+### .build
+
+Run a task or array of tasks.
+
+**Example**
+
+```js
+app.build('default', function(err, results) {
+  if (err) {
+    console.error(err);
+    return;
+  }
+  console.log(results);
+});
+```
+
+### .series
+
+Compose task or list of tasks into a single function that runs the tasks in series.
+
+**Params**
+
+* `tasks` **{String|Array|Function}**: List of tasks by name, function, or array of names/functions.
+* `returns` **{Function}**: Composed function that may take a callback function.
+
+**Example**
+
+```js
+app.task('foo', function(cb) {
+  console.log('this is foo');
+  cb();
+});
+
+var fn = app.series('foo', function(cb) {
+  console.log('this is bar');
+  cb();
+});
+
+fn(function(err) {
+  if (err) return console.error(err);
+  console.log('finished');
+});
+//=> this is foo
+//=> this is bar
+//=> finished
+```
+
+### .parallel
+
+Compose task or list of tasks into a single function that runs the tasks in parallel.
+
+**Params**
+
+* `tasks` **{String|Array|Function}**: List of tasks by name, function, or array of names/functions.
+* `returns` **{Function}**: Composed function that may take a callback function.
+
+**Example**
+
+```js
+app.task('foo', function(cb) {
+  setTimeout(function() {
+    console.log('this is foo');
+    cb();
+  }, 500);
+});
+
+var fn = app.parallel('foo', function(cb) {
+  console.log('this is bar');
+  cb();
+});
+
+fn(function(err) {
+  if (err) return console.error(err);
+  console.log('finished');
+});
+//=> this is bar
+//=> this is foo
+//=> finished
+```
+
+## Events
+
+The following events are emitted by [composer](https://github.com/jonschlinkert/composer). See the composer docs for more details
+
+### on.task
+
+Emitted when a `task` is `register`, `starting` and `finished`.
+
+```js
+app.on('task', function(task) {
+  console.log(task.status);
+  //=> 'register'
+});
+```
+
+### on.build
+
+Emitted when a `build` is `starting` and `finished`.
+
+```js
+app.on('build', function(build) {
+  console.log(build.status);
+  //=> 'starting'
+});
+```
+
+## History
+
+**v0.3.0**
+
+* Bumped [composer](https://github.com/doowb/composer) to v0.11.0, so the `.watch` method is no longer included by default. To add `.watch`, use the [base-watch](https://github.com/node-base/base-watch) plugin.

+
+Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```

+
+Returns true if a value is a valid instance of Base.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install is-valid-instance --save
+```
+
+## Usage
+
+Use in your [base][] plugin to ensure that the plugin is registered on a valid instance.
+
+```js
+var isValidInstance = require('is-valid-instance');
+
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stauff
+}
+```
+
+## API
+
+**Params**
+
+* `val` **{Object}**
+* `names` **{Array|Function}**: One or more names to check for on the given instance. Example `app` will check for `app.isApp === true` or `app._name === 'app'`.
+* `fn` **{Function}**: Custom function for validating the instance.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app)) return;
+  // do plugin stuff
+}
+```
+
+## Examples
+
+**Collection instance**
+
+Return true if the instance is a [templates][] view-collection (`views`):
+
+```js
+function plugin(collection) {
+  if (!isValidInstance(collection, ['views'])) {
+    // optionally return the plugin function so the plugin is re-tried on 
+    // each instance until it finds the correct one
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is a [templates][] view:
+
+```js
+function plugin(view) {
+  if (!isValidInstance(view, ['view'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```
+
+**View instance**
+
+Return true if the instance is either "app" or "collection":
+
+```js
+function plugin(app) {
+  if (!isValidInstance(app, ['app', 'collection'])) {
+    return plugin;
+  }
+  // do plugin stauff
+}
+```

+
+> base is the foundation for creating modular, unit testable and highly pluggable node.js applications, starting with a handful of common methods, like `set`, `get`, `del` and `use`.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save base
+```
+
+## What is Base?
+
+Base is a framework for rapidly creating high quality node.js applications, using plugins like building blocks.
+
+### Guiding principles
+
+The core team follows these principles to help guide API decisions:
+
+* **Compact API surface**: The smaller the API surface, the easier the library will be to learn and use.
+* **Easy to extend**: Implementors can use any npm package, and write plugins in pure JavaScript. If you're building complex apps, Base simplifies inheritance.
+* **Easy to test**: No special setup should be required to unit test `Base` or base plugins
+
+### Minimal API surface
+
+[The API](#api) was designed to provide only the minimum necessary functionality for creating a useful application, with or without [plugins](#plugins).
+
+**Base core**
+
+Base itself ships with only a handful of [useful methods](#api), such as:
+
+* `.set`: for setting values on the instance
+* `.get`: for getting values from the instance
+* `.has`: to check if a property exists on the instance
+* `.define`: for setting non-enumerable values on the instance
+* `.use`: for adding plugins
+
+**Be generic**
+
+When deciding on method to add or remove, we try to answer these questions:
+
+1. Will all or most Base applications need this method?
+2. Will this method encourage practices or enforce conventions that are beneficial to implementors?
+3. Can or should this be done in a plugin instead?
+
+### Composability
+
+**Plugin system**
+
+It couldn't be easier to extend Base with any features or custom functionality you can think of.
+
+Base plugins are just functions that take an instance of `Base`:
+
+```js
+var base = new Base();
+
+function plugin(base) {
+  // do plugin stuff, in pure JavaScript
+}
+// use the plugin
+base.use(plugin);
+```
+
+**Inheritance**
+
+Easily inherit Base using `.extend`:
+
+```js
+var Base = require('base');
+
+function MyApp() {
+  Base.call(this);
+}
+Base.extend(MyApp);
+
+var app = new MyApp();
+app.set('a', 'b');
+app.get('a');
+//=> 'b';
+```
+
+**Inherit or instantiate with a namespace**
+
+By default, the `.get`, `.set` and `.has` methods set and get values from the root of the `base` instance. You can customize this using the `.namespace` method exposed on the exported function. For example:
+
+```js
+var Base = require('base');
+// get and set values on the `base.cache` object
+var base = Base.namespace('cache');
+
+var app = base();
+app.set('foo', 'bar');
+console.log(app.cache.foo);
+//=> 'bar'
+```
+
+## API
+
+**Usage**
+
+```js
+var Base = require('base');
+var app = new Base();
+app.set('foo', 'bar');
+console.log(app.foo);
+//=> 'bar'
+```
+
+### [Base](index.js#L44)
+
+Create an instance of `Base` with the given `config` and `options`.
+
+**Params**
+
+* `config` **{Object}**: If supplied, this object is passed to [cache-base](https://github.com/jonschlinkert/cache-base) to merge onto the the instance upon instantiation.
+* `options` **{Object}**: If supplied, this object is used to initialize the `base.options` object.
+
+**Example**
+
+```js
+// initialize with `config` and `options`
+var app = new Base({isApp: true}, {abc: true});
+app.set('foo', 'bar');
+
+// values defined with the given `config` object will be on the root of the instance
+console.log(app.baz); //=> undefined
+console.log(app.foo); //=> 'bar'
+// or use `.get`
+console.log(app.get('isApp')); //=> true
+console.log(app.get('foo')); //=> 'bar'
+
+// values defined with the given `options` object will be on `app.options
+console.log(app.options.abc); //=> true
+```
+
+### [.is](index.js#L107)
+
+Set the given `name` on `app._name` and `app.is*` properties. Used for doing lookups in plugins.
+
+**Params**
+
+* `name` **{String}**
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+app.is('foo');
+console.log(app._name);
+//=> 'foo'
+console.log(app.isFoo);
+//=> true
+app.is('bar');
+console.log(app.isFoo);
+//=> true
+console.log(app.isBar);
+//=> true
+console.log(app._name);
+//=> 'bar'
+```
+
+### [.isRegistered](index.js#L145)
+
+Returns true if a plugin has already been registered on an instance.
+
+Plugin implementors are encouraged to use this first thing in a plugin
+to prevent the plugin from being called more than once on the same
+instance.
+
+**Params**
+
+* `name` **{String}**: The plugin name.
+* `register` **{Boolean}**: If the plugin if not already registered, to record it as being registered pass `true` as the second argument.
+* `returns` **{Boolean}**: Returns true if a plugin is already registered.
+
+**Events**
+
+* `emits`: `plugin` Emits the name of the plugin being registered. Useful for unit tests, to ensure plugins are only registered once.
+
+**Example**
+
+```js
+var base = new Base();
+base.use(function(app) {
+  if (app.isRegistered('myPlugin')) return;
+  // do stuff to `app`
+});
+
+// to also record the plugin as being registered
+base.use(function(app) {
+  if (app.isRegistered('myPlugin', true)) return;
+  // do stuff to `app`
+});
+```
+
+### [.use](index.js#L175)
+
+Define a plugin function to be called immediately upon init. Plugins are chainable and expose the following arguments to the plugin function:
+
+* `app`: the current instance of `Base`
+* `base`: the [first ancestor instance](#base) of `Base`
+
+**Params**
+
+* `fn` **{Function}**: plugin function to call
+* `returns` **{Object}**: Returns the item instance for chaining.
+
+**Example**
+
+```js
+var app = new Base()
+  .use(foo)
+  .use(bar)
+  .use(baz)
+```
+
+### [.define](index.js#L197)
+
+The `.define` method is used for adding non-enumerable property on the instance. Dot-notation is **not supported** with `define`.
+
+**Params**
+
+* `key` **{String}**: The name of the property to define.
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+// arbitrary `render` function using lodash `template`
+app.define('render', function(str, locals) {
+  return _.template(str)(locals);
+});
+```
+
+### [.mixin](index.js#L222)
+
+Mix property `key` onto the Base prototype. If base is inherited using `Base.extend` this method will be overridden by a new `mixin` method that will only add properties to the prototype of the inheriting application.
+
+**Params**
+
+* `key` **{String}**
+* `val` **{Object|Array}**
+* `returns` **{Object}**: Returns the `base` instance for chaining.
+
+**Example**
+
+```js
+app.mixin('foo', function() {
+  // do stuff
+});
+```
+
+### [.base](index.js#L268)
+
+Getter/setter used when creating nested instances of `Base`, for storing a reference to the first ancestor instance. This works by setting an instance of `Base` on the `parent` property of a "child" instance. The `base` property defaults to the current instance if no `parent` property is defined.
+
+**Example**
+
+```js
+// create an instance of `Base`, this is our first ("base") instance
+var first = new Base();
+first.foo = 'bar'; // arbitrary property, to make it easier to see what's happening later
+
+// create another instance
+var second = new Base();
+// create a reference to the first instance (`first`)
+second.parent = first;
+
+// create another instance
+var third = new Base();
+// create a reference to the previous instance (`second`)
+// repeat this pattern every time a "child" instance is created
+third.parent = second;
+
+// we can always access the first instance using the `base` property
+console.log(first.base.foo);
+//=> 'bar'
+console.log(second.base.foo);
+//=> 'bar'
+console.log(third.base.foo);
+//=> 'bar'
+// and now you know how to get to third base ;)
+```
+
+### [#use](index.js#L293)
+
+Static method for adding global plugin functions that will be added to an instance when created.
+
+**Params**
+
+* `fn` **{Function}**: Plugin function to use on each instance.
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.use(function(app) {
+  app.foo = 'bar';
+});
+var app = new Base();
+console.log(app.foo);
+//=> 'bar'
+```
+
+### [#extend](index.js#L337)
+
+Static method for inheriting the prototype and static methods of the `Base` class. This method greatly simplifies the process of creating inheritance-based applications. See [static-extend](https://github.com/jonschlinkert/static-extend) for more details.
+
+**Params**
+
+* `Ctor` **{Function}**: constructor to extend
+* `methods` **{Object}**: Optional prototype properties to mix in.
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+var extend = cu.extend(Parent);
+Parent.extend(Child);
+
+// optional methods
+Parent.extend(Child, {
+  foo: function() {},
+  bar: function() {}
+});
+```
+
+### [#mixin](index.js#L379)
+
+Used for adding methods to the `Base` prototype, and/or to the prototype of child instances. When a mixin function returns a function, the returned function is pushed onto the `.mixins` array, making it available to be used on inheriting classes whenever `Base.mixins()` is called (e.g. `Base.mixins(Child)`).
+
+**Params**
+
+* `fn` **{Function}**: Function to call
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.mixin(function(proto) {
+  proto.foo = function(msg) {
+    return 'foo ' + msg;
+  };
+});
+```
+
+### [#mixins](index.js#L401)
+
+Static method for running global mixin functions against a child constructor. Mixins must be registered before calling this method.
+
+**Params**
+
+* `Child` **{Function}**: Constructor function of a child class
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.extend(Child);
+Base.mixins(Child);
+```
+
+### [#inherit](index.js#L420)
+
+Similar to `util.inherit`, but copies all static properties, prototype properties, and getters/setters from `Provider` to `Receiver`. See [class-utils](https://github.com/jonschlinkert/class-utils#inherit) for more details.
+
+**Params**
+
+* `Receiver` **{Function}**: Receiving (child) constructor
+* `Provider` **{Function}**: Providing (parent) constructor
+* `returns` **{Object}**: Returns the `Base` constructor for chaining
+
+**Example**
+
+```js
+Base.inherit(Foo, Bar);
+```
+
+## In the wild

+The following node.js applications were built with `Base`:
+
+* [assemble](https://github.com/assemble/assemble)
+* [verb](https://github.com/verbose/verb)
+* [generate](https://github.com/generate/generate)
+* [scaffold](https://github.com/jonschlinkert/scaffold)
+* [boilerplate](https://github.com/jonschlinkert/boilerplate)

+
+> Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-accessor-descriptor
+```
+
+## Usage
+
+```js
+var isAccessor = require('is-accessor-descriptor');
+
+isAccessor({get: function() {}});
+//=> true
+```
+
+You may also pass an object and property name to check if the property is an accessor:
+
+```js
+isAccessor(foo, 'bar');
+```
+
+## Examples
+
+`false` when not an object
+
+```js
+isAccessor('a')
+isAccessor(null)
+isAccessor([])
+//=> false
+```
+
+`true` when the object has valid properties
+
+and the properties all have the correct JavaScript types:
+
+```js
+isAccessor({get: noop, set: noop})
+isAccessor({get: noop})
+isAccessor({set: noop})
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isAccessor({get: noop, set: noop, bar: 'baz'})
+isAccessor({get: noop, writable: true})
+isAccessor({get: noop, value: true})
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isAccessor({get: noop, set: 'baz'})
+isAccessor({get: 'foo', set: noop})
+isAccessor({get: 'foo', bar: 'baz'})
+isAccessor({get: 'foo', set: 'baz'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isAccessor({get: noop, set: noop, enumerable: 'foo'})
+isAccessor({set: noop, configurable: 'foo'})
+isAccessor({get: noop, configurable: 'foo'})
+//=> false
+```

+> Returns true if a value has the characteristics of a valid JavaScript data descriptor.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-data-descriptor
+```
+
+## Usage
+
+```js
+var isDataDesc = require('is-data-descriptor');
+```
+
+## Examples
+
+`true` when the descriptor has valid properties with valid values.
+
+```js
+// `value` can be anything
+isDataDesc({value: 'foo'})
+isDataDesc({value: function() {}})
+isDataDesc({value: true})
+//=> true
+```
+
+`false` when not an object
+
+```js
+isDataDesc('a')
+//=> false
+isDataDesc(null)
+//=> false
+isDataDesc([])
+//=> false
+```
+
+`false` when the object has invalid properties
+
+```js
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', get: function(){}})
+//=> false
+isDataDesc({get: function(){}, value: 'foo'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDataDesc({value: 'foo', enumerable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', configurable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', writable: 'foo'})
+//=> false
+```
+
+## Valid properties
+
+The only valid data descriptor properties are the following:
+
+* `configurable` (required)
+* `enumerable` (required)
+* `value` (optional)
+* `writable` (optional)
+
+To be a valid data descriptor, either `value` or `writable` must be defined.
+
+**Invalid properties**
+
+A descriptor may have additional _invalid_ properties (an error will **not** be thrown).
+
+```js
+var foo = {};
+
+Object.defineProperty(foo, 'bar', {
+  enumerable: true,
+  whatever: 'blah', // invalid, but doesn't cause an error
+  get: function() {
+    return 'baz';
+  }
+});
+
+console.log(foo.bar);
+//=> 'baz'
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false
+isDescriptor({get: noop, configurable: 'foo'});
+//=> false
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+
+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html), 
+as known from sh/bash, in JavaScript.
+
+[![build status](https://secure.travis-ci.org/juliangruber/brace-expansion.svg)](http://travis-ci.org/juliangruber/brace-expansion)
+[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)
+[![Greenkeeper badge](https://badges.greenkeeper.io/juliangruber/brace-expansion.svg)](https://greenkeeper.io/)
+
+[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation
+

+
+Fastest brace expansion for node.js, with the most complete support for the Bash 4.3 braces specification.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install braces --save
+```
+
+## Features
+
+* Complete support for the braces part of the [Bash 4.3 Brace Expansion](www.gnu.org/software/bash/). Braces passes [all of the relevant unit tests](#bash-4-3-support) from the spec.
+* Expands comma-separated values: `a/{b,c}/d` => `['a/b/d', 'a/c/d']`
+* Expands alphabetical or numerical ranges: `{1..3}` => `['1', '2', '3']`
+* [Very fast](#benchmarks)
+* [Special characters](./patterns.md) can be used to generate interesting patterns.
+
+## Example usage
+
+```js
+var braces = require('braces');
+
+braces('a/{x,y}/c{d}e')
+//=> ['a/x/cde', 'a/y/cde']
+
+braces('a/b/c/{x,y}')
+//=> ['a/b/c/x', 'a/b/c/y']
+
+braces('a/{x,{1..5},y}/c{d}e')
+//=> ['a/x/cde', 'a/1/cde', 'a/y/cde', 'a/2/cde', 'a/3/cde', 'a/4/cde', 'a/5/cde']
+```
+
+### Use case: fixtures
+
+> Use braces to generate test fixtures!
+
+**Example**
+
+```js
+var braces = require('./');
+var path = require('path');
+var fs = require('fs');
+
+braces('blah/{a..z}.js').forEach(function(fp) {
+  if (!fs.existsSync(path.dirname(fp))) {
+    fs.mkdirSync(path.dirname(fp));
+  }
+  fs.writeFileSync(fp, '');
+});
+```
+
+See the [tests](./test/test.js) for more examples and use cases (also see the [bash spec tests](./test/bash-mm-adjusted.js));
+
+### Range expansion
+
+Uses [expand-range](https://github.com/jonschlinkert/expand-range) for range expansion.
+
+```js
+braces('a{1..3}b')
+//=> ['a1b', 'a2b', 'a3b']
+
+braces('a{5..8}b')
+//=> ['a5b', 'a6b', 'a7b', 'a8b']
+
+braces('a{00..05}b')
+//=> ['a00b', 'a01b', 'a02b', 'a03b', 'a04b', 'a05b']
+
+braces('a{01..03}b')
+//=> ['a01b', 'a02b', 'a03b']
+
+braces('a{000..005}b')
+//=> ['a000b', 'a001b', 'a002b', 'a003b', 'a004b', 'a005b']
+
+braces('a{a..e}b')
+//=> ['aab', 'abb', 'acb', 'adb', 'aeb']
+
+braces('a{A..E}b')
+//=> ['aAb', 'aBb', 'aCb', 'aDb', 'aEb']
+```
+
+Pass a function as the last argument to customize range expansions:
+
+```js
+var range = braces('x{a..e}y', function (str, i) {
+  return String.fromCharCode(str) + i;
+});
+
+console.log(range);
+//=> ['xa0y', 'xb1y', 'xc2y', 'xd3y', 'xe4y']
+```
+
+See [expand-range](https://github.com/jonschlinkert/expand-range) for benchmarks, tests and the full list of range expansion features.
+
+## Options
+
+### options.makeRe
+
+Type: `Boolean`
+
+Deafault: `false`
+
+Return a regex-optimal string. If you're using braces to generate regex, this will result in dramatically faster performance.
+
+**Examples**
+
+With the default settings (`{makeRe: false}`):
+
+```js
+braces('{1..5}');
+//=> ['1', '2', '3', '4', '5']
+```
+
+With `{makeRe: true}`:
+
+```js
+braces('{1..5}', {makeRe: true});
+//=> ['[1-5]']
+
+braces('{3..9..3}', {makeRe: true});
+//=> ['(3|6|9)']
+```
+
+### options.bash
+
+Type: `Boolean`
+
+Default: `false`
+
+Enables complete support for the Bash specification. The downside is a 20-25% speed decrease.
+
+**Example**
+
+Using the default setting (`{bash: false}`):
+
+```js
+braces('a{b}c');
+//=> ['abc']
+```
+
+In bash (and minimatch), braces with one item are not expanded. To get the same result with braces, set `{bash: true}`:
+
+```js
+braces('a{b}c', {bash: true});
+//=> ['a{b}c']
+```
+
+### options.nodupes
+
+Type: `Boolean`
+
+Deafault: `true`
+
+Duplicates are removed by default. To keep duplicates, pass `{nodupes: false}` on the options
+
+## Bash 4.3 Support
+
+> Better support for Bash 4.3 than minimatch
+
+This project has comprehensive unit tests, including tests coverted from [Bash 4.3](www.gnu.org/software/bash/). Currently only 8 of 102 unit tests fail, and

+
+```js
+var Cache = require('cache-base').namespace('data');
+var app = new Cache();
+app.set('a', 'b');
+console.log(app.data);
+//=> {a: 'b'}
+```
+
+## API
+
+### [namespace](index.js#L29)
+
+Create a `Cache` constructor that when instantiated will store values on the given `prop`.
+
+**Params**
+
+* `prop` **{String}**: The property name to use for storing values.
+* `returns` **{Function}**: Returns a custom `Cache` constructor
+
+**Example**
+
+```js
+var Cache = require('cache-base').namespace('data');
+var cache = new Cache();
+
+cache.set('foo', 'bar');
+//=> {data: {foo: 'bar'}}
+```
+
+### [Cache](index.js#L43)
+
+Create a new `Cache`. Internally the `Cache` constructor is created using the `namespace` function, with `cache` defined as the storage object.
+
+**Params**
+
+* `cache` **{Object}**: Optionally pass an object to initialize with.
+
+**Example**
+
+```js
+var app = new Cache();
+```
+
+### [.set](index.js#L84)
+
+Assign `value` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `set` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.on('set', function(key, val) {
+  // do something when `set` is emitted
+});
+
+app.set(key, value);
+
+// also takes an object or array
+app.set({name: 'Halle'});
+app.set([{foo: 'bar'}, {baz: 'quux'}]);
+console.log(app);
+//=> {name: 'Halle', foo: 'bar', baz: 'quux'}
+```
+
+### [.union](index.js#L114)
+
+Union `array` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+app.union('a.b', ['foo']);
+app.union('a.b', ['bar']);
+console.log(app.get('a'));
+//=> {b: ['foo', 'bar']}
+```
+
+### [.get](index.js#L144)
+
+Return the value of `key`. Dot notation may be used to get [nested property values](https://github.com/jonschlinkert/get-value).
+
+**Params**
+
+* `key` **{String}**: The name of the property to get. Dot-notation may be used.
+* `returns` **{any}**: Returns the value of `key`
+
+**Events**
+
+* `emits`: `get` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.set('a.b.c', 'd');
+app.get('a.b');
+//=> {c: 'd'}
+
+app.get(['a', 'b']);
+//=> {c: 'd'}
+```
+
+### [.has](index.js#L171)
+
+Return true if app has a stored value for `key`, false only if value is `undefined`.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{Boolean}**
+
+**Events**
+
+* `emits`: `has` with `key` and true or false as arguments.
+
+**Example**
+
+```js
+app.set('foo', 'bar');
+app.has('foo');
+//=> true
+```
+
+### [.del](index.js#L199)
+
+Delete one or more properties from the instance.
+
+**Params**
+
+* `key` **{String|Array}**: Property name or array of property names.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `del` with the `key` as the only argument.
+
+**Example**
+
+```js
+app.del(); // delete all
+// or
+app.del('foo');
+// or
+app.del(['foo', 'bar']);
+```
+
+### [.clear](index.js#L218)
+
+Reset the entire cache to an empty object.
+
+**Example**
+
+```js
+app.clear();
+```
+
+### [.visit](index.js#L235)
+
+Visit `method` over the properties in the given object, or map
+visit over the object-elements in an array.
+
+**Params**
+
+* `method` **{String}**: The name of the `base` method to call.
+* `val` **{Object|Array}**: The object or array to iterate over.
+* `returns` **{Object}**: Returns the instance for chaining.

+
+> Returns true if a value exists, false if empty. Works with deeply nested values using object paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-value
+```
+
+**Works for:**
+
+* booleans
+* functions
+* numbers
+* strings
+* nulls
+* object
+* arrays
+
+## Usage
+
+Works with property values (supports object-path notation, like `foo.bar`) or a single value:
+
+```js
+var hasValue = require('has-value');
+
+hasValue('foo');
+hasValue({foo: 'bar'}, 'foo');
+hasValue({a: {b: {c: 'foo'}}}, 'a.b.c');
+//=> true
+
+hasValue('');
+hasValue({foo: ''}, 'foo');
+//=> false
+
+hasValue(0);
+hasValue(1);
+hasValue({foo: 0}, 'foo');
+hasValue({foo: 1}, 'foo');
+hasValue({foo: null}, 'foo');
+hasValue({foo: {bar: 'a'}}}, 'foo');
+hasValue({foo: {bar: 'a'}}}, 'foo.bar');
+//=> true
+
+hasValue({foo: {}}}, 'foo');
+hasValue({foo: {bar: {}}}}, 'foo.bar');
+hasValue({foo: undefined}, 'foo');
+//=> false
+
+hasValue([]);
+hasValue([[]]);
+hasValue([[], []]);
+hasValue([undefined]);
+hasValue({foo: []}, 'foo');
+//=> false
+
+hasValue([0]);
+hasValue([null]);
+hasValue(['foo']);
+hasValue({foo: ['a']}, 'foo');
+//=> true
+
+hasValue(function() {})
+hasValue(function(foo) {})
+hasValue({foo: function(foo) {}}, 'foo'); 
+hasValue({foo: function() {}}, 'foo');
+//=> true
+
+hasValue(true);
+hasValue(false);
+hasValue({foo: true}, 'foo');
+hasValue({foo: false}, 'foo');
+//=> true
+```
+
+## isEmpty
+
+To do the opposite and test for empty values, do:
+
+```js
+function isEmpty(o) {
+  return !hasValue.apply(hasValue, arguments);
+}
+```
+
+## Release history
+
+### v1.0.0
+
+* `zero` always returns true
+* `array` now recurses, so that an array of empty arrays will return `false`
+* `null` now returns true

+
+> Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save set-value
+```
+
+## Usage
+
+```js
+var set = require('set-value');
+set(object, prop, value);
+```
+
+### Params
+
+* `object` **{object}**: The object to set `value` on
+* `prop` **{string}**: The property to set. Dot-notation may be used.
+* `value` **{any}**: The value to set on `object[prop]`
+
+## Examples
+
+Updates and returns the given object:
+
+```js
+var obj = {};
+set(obj, 'a.b.c', 'd');
+console.log(obj);
+//=> { a: { b: { c: 'd' } } }
+```
+
+### Escaping
+
+**Escaping with backslashes**
+
+Prevent set-value from splitting on a dot by prefixing it with backslashes:
+
+```js
+console.log(set({}, 'a\\.b.c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, 'a\\.b\\.c', 'd'));
+//=> { 'a.b.c': 'd' }
+```
+
+**Escaping with double-quotes or single-quotes**
+
+Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:
+
+```js
+console.log(set({}, '"a.b".c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, "'a.b'.c", "d"));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, '"this/is/a/.file.path"', 'd'));
+//=> { 'this/is/a/file.path': 'd' }
+```
+
+### Bracket support
+
+set-value does not split inside brackets or braces:
+
+```js
+console.log(set({}, '[a.b].c', 'd'));
+//=> { '[a.b]': { c: 'd' } }
+
+console.log(set({}, "(a.b).c", "d"));
+//=> { '(a.b)': { c: 'd' } }
+
+console.log(set({}, "<a.b>.c", "d"));
+//=> { '<a.b>': { c: 'd' } }
+
+console.log(set({}, "{a..b}.c", "d"));
+//=> { '{a..b}': { c: 'd' } }
+```
+
+## History
+
+### v2.0.0
+
+* Adds support for escaping with double or single quotes. See [escaping](#escaping) for examples.
+* Will no longer split inside brackets or braces. See [bracket support](#bracket-support) for examples.
+
+If there are any regressions please create a [bug report](../../issues/new). Thanks!

+> Terminal string styling done right
+
+[![Build Status](https://travis-ci.org/chalk/chalk.svg?branch=master)](https://travis-ci.org/chalk/chalk)
+[![Coverage Status](https://coveralls.io/repos/chalk/chalk/badge.svg?branch=master)](https://coveralls.io/r/chalk/chalk?branch=master)
+[![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)](https://www.youtube.com/watch?v=9auOCbH5Ns4)
+
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
+
+**Chalk is a clean and focused alternative.**
+
+![](https://github.com/chalk/ansi-styles/raw/master/screenshot.png)
+
+
+## Why
+
+- Highly performant
+- Doesn't extend `String.prototype`
+- Expressive API
+- Ability to nest styles
+- Clean and focused
+- Auto-detects color support
+- Actively maintained
+- [Used by ~4500 modules](https://www.npmjs.com/browse/depended/chalk) as of July 15, 2015
+
+
+## Install
+
+```
+$ npm install --save chalk
+```
+
+
+## Usage
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+var chalk = require('chalk');
+
+// style a string
+chalk.blue('Hello world!');
+
+// combine styled and normal strings
+chalk.blue('Hello') + 'World' + chalk.red('!');
+
+// compose multiple styles using the chainable API
+chalk.blue.bgRed.bold('Hello world!');
+
+// pass in multiple arguments
+chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz');
+
+// nest styles
+chalk.red('Hello', chalk.underline.bgBlue('world') + '!');
+
+// nest styles of the same type even (color, underline, background)
+chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+);
+```
+
+Easily define your own themes.
+
+```js
+var chalk = require('chalk');
+var error = chalk.bold.red;
+console.log(error('Error!'));
+```
+
+Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
+
+```js
+var name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> Hello Sindre
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `Chalk.red.yellow.green` is equivalent to `Chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, but you can override it by setting the `enabled` property. You should however only do this in your own code as it applies globally to all chalk consumers.
+
+If you need to change this in a reusable module create a new instance:
+
+```js
+var ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
+
+### chalk.styles
+
+Exposes the styles as [ANSI escape codes](https://github.com/chalk/ansi-styles).
+
+Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with your own.
+
+```js
+var chalk = require('chalk');
+
+console.log(chalk.styles.red);
+//=> {open: '\u001b[31m', close: '\u001b[39m'}
+
+console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
+```
+
+### chalk.hasColor(string)
+
+Check whether a string [has color](https://github.com/chalk/has-ansi).
+
+### chalk.stripColor(string)
+
+[Strip color](https://github.com/chalk/strip-ansi) from a string.
+
+Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
+
+Example:
+
+```js
+var chalk = require('chalk');
+var styledString = getText();
+
+if (!chalk.supportsColor) {
+	styledString = chalk.stripColor(styledString);
+}
+```
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue` *(on Windows the bright version is used as normal blue is illegible)*
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## 256-colors
+
+Chalk does not support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://bliker.github.io/cmder/) instead of `cmd.exe`.

+
+**Params**
+
+* `obj` **{Object}**: Object that has a `constructor`.
+* `returns` **{Array}**: Array of keys.
+
+**Example**

+function App() {}
+Object.defineProperty(App.prototype, 'count', {
+  get: function() {
+    return Object.keys(this).length;
+  }
+});
+cu.getDescriptor(App.prototype, 'count');
+// returns:
+// {
+//   get: [Function],
+//   set: undefined,
+//   enumerable: false,
+//   configurable: false
+// }
+```
+
+### [.copyDescriptor](index.js#L238)
+
+Copy a descriptor from one object to another.
+
+**Params**

+Object.defineProperty(App.prototype, 'count', {
+  get: function() {
+    return Object.keys(this).length;
+  }
+});
+var obj = {};
+cu.copyDescriptor(obj, App.prototype, 'count');
+```
+
+### [.copy](index.js#L264)
+
+Copy static properties, prototype properties, and descriptors
+from one object to another.
+
+**Params**

+* `receiver` **{Object}**
+* `provider` **{Object}**
+* `omit` **{String|Array}**: One or more properties to omit
+* `returns` **{Object}**
+
+### [.extend](index.js#L343)
+
+Returns a function for extending the static properties, prototype properties, and descriptors from the `Parent` constructor onto `Child` constructors.
+
+**Params**
+
+* `Parent` **{Function}**: Parent ctor
+* `extend` **{Function}**: Optional extend function to handle custom extensions. Useful when updating methods that require a specific prototype.
+* `Child` **{Function}**: Child ctor

+cli-width
+=========
+
+Get stdout window width, with three fallbacks, `tty`, a custom environment variable and then a default.
+
+[![npm version](https://badge.fury.io/js/cli-width.svg)](http://badge.fury.io/js/cli-width)
+[![Build Status](https://travis-ci.org/knownasilya/cli-width.svg)](https://travis-ci.org/knownasilya/cli-width)
+[![Coverage Status](https://coveralls.io/repos/knownasilya/cli-width/badge.svg?branch=master&service=github)](https://coveralls.io/github/knownasilya/cli-width?branch=master)
+
+## Usage
+
+```
+npm install --save cli-width
+```
+
+```js
+'use stict';
+
+var cliWidth = require('cli-width');
+
+cliWidth(); // maybe 204 :)
+```
+
+You can also set the `CLI_WIDTH` environment variable.
+
+If none of the methods are supported, and the environment variable isn't set,
+the default is `0` and can be changed via `cliWidth.defaultWidth = 200;`.

+Easier Buffer cloning in node.
+
+## Example
+
+```js
+var cloneBuffer = require('clone-buffer');
+
+var buffer = new Buffer('test');
+var cloned = cloneBuffer(buffer);
+// buffer !== cloned
+```
+
+## API
+
+### `cloneBuffer(buffer)`
+
+Takes a `Buffer` object and returns a clone.  Throws if a non-`Buffer` is passed.

+# clone-deep [![NPM version](https://img.shields.io/npm/v/clone-deep.svg)](https://www.npmjs.com/package/clone-deep) [![Build Status](https://img.shields.io/travis/jonschlinkert/clone-deep.svg)](https://travis-ci.org/jonschlinkert/clone-deep)
+
+> Recursively (deep) clone JavaScript native types, like Object, Array, RegExp, Date as well as primitives.
+
+The `instanceClone` function is invoked to clone objects that are not "plain" objects (as defined by [](#isPlainObject)`isPlainObject`) if it is provided. If `instanceClone` is not specified, it will not attempt to clone non-plain objects, and will copy the object reference.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i clone-deep --save
+```
+
+## Usage
+
+```js
+var cloneDeep = require('clone-deep');
+
+var obj = {a: 'b'};
+var arr = [obj];
+
+var copy = cloneDeep(arr);
+obj.c = 'd';
+
+console.log(copy);
+//=> [{a: 'b'}]
+
+console.log(arr);
+//=> [{a: 'b', c: 'd'}]
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+# clone
+
+[![build status](https://secure.travis-ci.org/pvorb/node-clone.png)](http://travis-ci.org/pvorb/node-clone)
+
+[![info badge](https://nodei.co/npm/clone.png?downloads=true&downloadRank=true&stars=true)](http://npm-stat.com/charts.html?package=clone)
+
+offers foolproof _deep cloning_ of objects, arrays, numbers, strings etc. in JavaScript.
+
+
+## Installation
+
+    npm install clone
+
+(It also works with browserify, ender or standalone.)
+
+
+## Example
+
+~~~ javascript
+var clone = require('clone');
+
+var a, b;
+
+a = { foo: { bar: 'baz' } };  // initial value of a
+
+b = clone(a);                 // clone a -> b
+a.foo.bar = 'foo';            // change a
+
+console.log(a);               // show a
+console.log(b);               // show b
+~~~
+
+This will print:
+
+~~~ javascript
+{ foo: { bar: 'foo' } }
+{ foo: { bar: 'baz' } }
+~~~
+
+**clone** masters cloning simple objects (even with custom prototype), arrays,
+Date objects, and RegExp objects. Everything is cloned recursively, so that you
+can clone dates in arrays in objects, for example.
+
+
+## API
+
+`clone(val, circular, depth)`
+
+  * `val` -- the value that you want to clone, any type allowed
+  * `circular` -- boolean
+
+    Call `clone` with `circular` set to `false` if you are certain that `obj`
+    contains no circular references. This will give better performance if needed.
+    There is no error if `undefined` or `null` is passed as `obj`.
+  * `depth` -- depth to which the object is to be cloned (optional,
+    defaults to infinity)
+
+`clone.clonePrototype(obj)`
+
+  * `obj` -- the object that you want to clone
+
+Does a prototype clone as
+[described by Oran Looney](http://oranlooney.com/functional-javascript/).
+
+
+## Circular References
+
+~~~ javascript
+var a, b;
+
+a = { hello: 'world' };
+
+a.myself = a;
+b = clone(a);
+
+console.log(b);
+~~~
+
+This will print:
+
+~~~ javascript
+{ hello: "world", myself: [Circular] }
+~~~
+
+So, `b.myself` points to `b`, not `a`. Neat!
+
+
+## Test
+
+    npm test
+
+
+## Caveat
+
+Some special objects like a socket or `process.stdout`/`stderr` are known to not
+be cloneable. If you find other objects that cannot be cloned, please [open an
+issue](https://github.com/pvorb/node-clone/issues/new).
+
+
+## Bugs and Issues
+
+If you encounter any bugs or issues, feel free to [open an issue at
+github](https://github.com/pvorb/node-clone/issues) or send me an email to
+<paul@vorba.ch>. I also always like to hear from you, if you’re using my code.

+
+[![Build Status](https://travis-ci.org/mcollina/cloneable-readable.svg?branch=master)](https://travis-ci.org/mcollina/cloneable-readable)
+
+Clone a Readable stream, safely.
+
+```js
+'use strict'
+
+var cloneable = require('cloneable-readable')
+var fs = require('fs')
+var pump = require('pump')
+
+var stream = cloneable(fs.createReadStream('./package.json'))
+
+pump(stream.clone(), fs.createWriteStream('./out1'))
+
+// simulate some asynchronicity
+setImmediate(function () {
+  pump(stream, fs.createWriteStream('./out2'))
+})
+```
+
+**cloneable-readable** automatically handles `objectMode: true`.
+
+This module comes out of an healthy discussion on the 'right' way to
+clone a Readable in https://github.com/gulpjs/vinyl/issues/85
+and https://github.com/nodejs/readable-stream/issues/202. This is my take.
+
+**YOU MUST PIPE ALL CLONES TO START THE FLOW**
+
+You can also attach `'data'` and `'readable'` events to them.
+
+## API
+
+### cloneable(stream)
+
+Create a `Cloneable` stream.
+A Cloneable has a `clone()` method to create more clones.
+All clones must be resumed/piped to start the flow.
+
+### cloneable.isCloneable(stream)
+
+Check if `stream` needs to be wrapped in a `Cloneable` or not.

+
+  Generator based control flow goodness for nodejs and the browser,
+  using promises, letting you write non-blocking code in a nice-ish way.
+
+## Co v4
+
+  `co@4.0.0` has been released, which now relies on promises.
+  It is a stepping stone towards [ES7 async/await](https://github.com/lukehoban/ecmascript-asyncawait).
+  The primary API change is how `co()` is invoked.
+  Before, `co` returned a "thunk", which you then called with a callback and optional arguments.
+  Now, `co()` returns a promise.
+
+```js
+co(function* () {
+  var result = yield Promise.resolve(true);
+  return result;
+}).then(function (value) {
+  console.log(value);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+  If you want to convert a `co`-generator-function into a regular function that returns a promise,
+  you now use `co.wrap(fn*)`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```
+
+## Platform Compatibility
+
+  `co@4+` requires a `Promise` implementation.
+  For versions of node `< 0.11` and for many older browsers,
+  you should/must include your own `Promise` polyfill.
+
+  When using node 0.11.x or greater, you must use the `--harmony-generators`
+  flag or just `--harmony` to get access to generators.
+
+  When using node 0.10.x and lower or browsers without generator support,
+  you must use [gnode](https://github.com/TooTallNate/gnode) and/or [regenerator](http://facebook.github.io/regenerator/).
+
+  io.js is supported out of the box, you can use `co` without flags or polyfills.
+
+## Installation
+
+```
+$ npm install co
+```
+
+## Associated libraries
+
+Any library that returns promises work well with `co`.
+
+- [mz](https://github.com/normalize/mz) - wrap all of node's code libraries as promises.
+
+View the [wiki](https://github.com/visionmedia/co/wiki) for more libraries.
+
+## Examples
+
+```js
+var co = require('co');
+
+co(function *(){
+  // yield any promise
+  var result = yield Promise.resolve(true);
+}).catch(onerror);
+
+co(function *(){
+  // resolve multiple promises in parallel
+  var a = Promise.resolve(1);
+  var b = Promise.resolve(2);
+  var c = Promise.resolve(3);
+  var res = yield [a, b, c];
+  console.log(res);
+  // => [1, 2, 3]
+}).catch(onerror);
+
+// errors can be try/catched
+co(function *(){
+  try {
+    yield Promise.reject(new Error('boom'));
+  } catch (err) {
+    console.error(err.message); // "boom"
+ }
+}).catch(onerror);
+
+function onerror(err) {
+  // log any uncaught errors
+  // co will not throw any errors you do not handle!!!
+  // HANDLE ALL YOUR ERRORS!!!
+  console.error(err.stack);
+}
+```
+
+## Yieldables
+
+  The `yieldable` objects currently supported are:
+
+  - promises
+  - thunks (functions)
+  - array (parallel execution)
+  - objects (parallel execution)
+  - generators (delegation)
+  - generator functions (delegation)
+
+Nested `yieldable` objects are supported, meaning you can nest
+promises within objects within arrays, and so on!
+
+### Promises
+
+[Read more on promises!](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
+
+### Thunks
+
+Thunks are functions that only have a single argument, a callback.
+Thunk support only remains for backwards compatibility and may
+be removed in future versions of `co`.
+
+### Arrays
+
+`yield`ing an array will resolve all the `yieldables` in parallel.
+
+```js
+co(function* () {
+  var res = yield [
+    Promise.resolve(1),
+    Promise.resolve(2),
+    Promise.resolve(3),
+  ];
+  console.log(res); // => [1, 2, 3]
+}).catch(onerror);
+```
+
+### Objects
+
+Just like arrays, objects resolve all `yieldable`s in parallel.
+
+```js
+co(function* () {
+  var res = yield {
+    1: Promise.resolve(1),
+    2: Promise.resolve(2),
+  };
+  console.log(res); // => { 1: 1, 2: 2 }
+}).catch(onerror);
+```
+
+### Generators and Generator Functions
+
+Any generator or generator function you can pass into `co`
+can be yielded as well. This should generally be avoided
+as we should be moving towards spec-compliant `Promise`s instead.
+
+## API
+
+### co(fn*).then( val => )
+
+Returns a promise that resolves a generator, generator function,
+or any function that returns a generator.
+
+```js
+co(function* () {
+  return yield Promise.resolve(true);
+}).then(function (val) {
+  console.log(val);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+### var fn = co.wrap(fn*)
+
+Convert a generator into a regular function that returns a `Promise`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```

+> A wrapper around inquirer that makes it easy to create and selectively reuse questions.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install question-cache --save
+```
+
+## Example
+
+```js
+var questions = require('question-cache');
+
+questions()
+  .set('first', 'What is your first name?')
+  .set('last', 'What is your last name?')
+  .ask(function(err, answers) {
+    console.log(answers);
+  });
+```

+
+See the [working examples](./examples).
+
+## Basic Usage
+
+See the [working examples](./examples).
+
+```js
+var questions = require('question-cache')();
+
+// question type "input" is used by default
+questions
+  .set('name', 'What is your name?')
+  .ask('name', function (err, answers) {
+    console.log(answers);
+  });
+```
+
+**[inquirer2](https://github.com/jonschlinkert/inquirer2)**
+
+You may optionally pass your own instance of inquirer to the constructor:
+
+```js
+// on the options
+var questions = require('question-cache');
+var questions = new Questions({
+  inquirer: require('inquirer2')
+});
+
+// or if inquirer is the only thing passed
+var questions = new Questions(require('inquirer2'));
+```
+
+## Getting started
+
+question-cache is a wrapper around [inquirer2](https://github.com/jonschlinkert/inquirer2). If you have any issues related to the interface (like scrolling, colors, styling, etc), then please create an issue on the [inquirer2](https://github.com/jonschlinkert/inquirer2) project.
+
+**Asking questions**
+
+The simplest way to ask a question is by passing a string and a callback:
+
+```js
+questions.ask('name', function (err, answers) {
+  console.log(answers);
+});
+```
+
+**Ask all cached questions**
+
+```js
+questions.ask(function (err, answers) {
+  console.log(answers);
+});
+```
+
+## API
+
+### [Questions](index.js#L28)
+
+Create an instance of `Questions` with the given `options`.
+
+**Params**
+
+* `options` **{Object}**: question cache options
+
+**Example**
+
+```js
+var Questions = new Questions(options);
+```
+
+### [.set](index.js#L90)
+
+Calls [addQuestion](#addQuestion), with the only difference being that `.set` returns the `questions` instance and `.addQuestion` returns the question object. So use `.set` if you want to chain questions, or `.addQuestion` if you need the created question object.
+
+**Params**
+
+* `name` **{Object|String}**: Question name, message (string), or question/options object.
+* `value` **{Object|String}**: Question message (string), or question/options object.
+* `options` **{Object|String}**: Question/options object.
+
+**Example**
+
+```js
+questions
+  .set('drink', 'What is your favorite beverage?')
+  .set('color', 'What is your favorite color?')
+  .set('season', 'What is your favorite season?');
+
+// or
+questions.set('drink', {
+  type: 'input',
+  message: 'What is your favorite beverage?'
+});
+
+// or
+questions.set({
+  name: 'drink'
+  type: 'input',
+  message: 'What is your favorite beverage?'
+});
+```
+
+### [.addQuestion](index.js#L122)
+
+Add a question to be asked at a later point. Creates an instance of [Question](#question), so any `Question` options or settings may be used. Also, the default `type` is `input` if not defined by the user.
+
+**Params**
+
+* `name` **{Object|String}**: Question name, message (string), or question/options object.
+* `value` **{Object|String}**: Question message (string), or question/options object.
+* `options` **{Object|String}**: Question/options object.
+
+**Example**
+
+```js
+questions.addQuestion('drink', 'What is your favorite beverage?');
+
+// or
+questions.addQuestion('drink', {
+  type: 'input',
+  message: 'What is your favorite beverage?'
+});
+
+// or
+questions.addQuestion({
+  name: 'drink'
+  type: 'input',
+  message: 'What is your favorite beverage?'

+
+* `queue` **{String|Array}**: Name or array of question names.
+* `options` **{Object|Function}**: Question options or callback function
+* `callback` **{Function}**: callback function

+});
+```
+
+### [.get](index.js#L297)

+
+**Params**
+
+* `name` **{String}**
+* `returns` **{Object}**: Returns the question object.
+
+**Example**
+
+```js
+var name = questions.get('name');
+//=> question object
+```
+
+### [.has](index.js#L313)
+
+Returns true if `questions.cache` or `questions.groups` has question `name`.
+
+* `returns` **{String}**: The name of the question to check
+
+**Example**
+
+```js
+var name = questions.has('name');
+//=> true
+```
+
+### [.del](index.js#L338)
+
+Delete the given question or any questions that have the given namespace using dot-notation.
+
+* `returns` **{String}**: The name of the question to delete
+
+**Example**

+```js
+questions.del('name');
+questions.get('name');
+//=> undefined
+
+// using dot-notation
+questions.del('author');
+questions.get('author.name');
+//=> undefined
+```
+
+### [.clearAnswers](index.js#L356)
+
+Clear all cached answers.
+
+**Example**
+
+```js
+questions.clearAnswers();
+```
+
+### [.clearQuestions](index.js#L371)
+
+Clear all questions from the cache.
+
+**Example**
+
+```js
+questions.clearQuestions();
+```
+
+### [.clear](index.js#L386)

+
+**Params**
+
+* `queue` **{String|Array}**: Name or array of question names.
+* `options` **{Object|Function}**: Question options or callback function
+* `callback` **{Function}**: callback function
+
+**Example**

+  console.log(answers);
+});
+```
+
+### [.normalize](index.js#L531)
+
+Normalize the given value to return an array of question keys.
+
+**Params**
+
+* **{[type]}**: key
+* `returns` **{[type]}**
+
+## Dot notation
+
+See the [working examples](./examples).
+
+Qestions may be cached using object-path notatation (e.g. `a.b.c`).
+
+**Example**
+
+All of the following will be cached on the `name` object:
+
+```js
+questions
+  .set('name.first', 'What is your first name?')
+  .set('name.middle', 'What is your middle name?')
+  .set('name.last', 'What is your last name?')
+```
+
+**Dot notation usage**
+
+When cached using dot-notation, there are a few different ways questions that may be asked.
+
+### Dot notation usage
+
+#### ask one
+
+Ask a single `name` question:
+
+```js
+questions.ask('name.first', function (err, answers) {
+  console.log(answers);
+});
+```
+
+#### ask all "name" questions
+
+Ask all `name` questions, `first`, `middle` and `last`:
+
+```js
+questions.ask('name', function (err, answers) {
+  console.log(answers);
+});
+```
+
+#### array of questions
+
+Ask specific questions on `name`:
+
+```js
+questions.ask(['name.first', 'name.last'], function (err, answers) {
+  console.log(answers);
+});
+```
+
+#### ask all questions
+
+Ask specific questions on `name`:
+
+```js
+questions
+  .set('name.first', {
+    message: 'What is your first name?',
+  })
+  .set('name.last', {
+    message: 'What is your last name?',
+  })
+  .set('foo', {
+    message: 'Any thoughts about foo?',
+  })
+
+questions.ask(['name', 'foo'], function (err, answers) {
+  console.log(answers);
+});
+```
+
+#### nested questions
+
+Ask one question at a time, based on feedback:
+
+```js
+questions.ask('name.first', function (err, answers) {
+  console.log(answers);
+  //=> {name: { first: 'Brian' }}
+
+  questions.ask('name.last', function (err, answers) {
+    console.log(answers);
+    //=> {name: { last: 'Woodward' }}
+  });
+});
+```
+
+## More examples
+
+### Mixture of dot notation and non-dot-notation
+
+Given you have the following questions:
+
+```js
+questions
+  .set('name.first', 'What is your first name?')
+  .set('name.last', 'What is your last name?')
+  .set('foo', 'Any thoughts about foo?')
+  .set('bar', 'Any thoughts about bar?')
+```
+
+The following will ask questions: `name.first`, `name.last` and `foo`
+
+```js
+questions.ask(['name', 'foo'], function (err, answers) {
+  console.log(answers);
+});
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)
+
+  Event emitter component.
+
+## Installation
+
+```
+$ component install component/emitter
+```
+
+## API
+
+### Emitter(obj)
+
+  The `Emitter` may also be used as a mixin. For example
+  a "plain" object may become an emitter, or you may
+  extend an existing prototype.
+
+  As an `Emitter` instance:
+
+```js
+var Emitter = require('emitter');
+var emitter = new Emitter;
+emitter.emit('something');
+```
+
+  As a mixin:
+
+```js
+var Emitter = require('emitter');
+var user = { name: 'tobi' };
+Emitter(user);
+
+user.emit('im a user');
+```
+
+  As a prototype mixin:
+
+```js
+var Emitter = require('emitter');
+Emitter(User.prototype);
+```
+
+### Emitter#on(event, fn)
+
+  Register an `event` handler `fn`.
+
+### Emitter#once(event, fn)
+
+  Register a single-shot `event` handler `fn`,
+  removed immediately after it is invoked the
+  first time.
+
+### Emitter#off(event, fn)
+
+  * Pass `event` and `fn` to remove a listener.
+  * Pass `event` to remove all listeners on that event.
+  * Pass nothing to remove all listeners on all events.
+
+### Emitter#emit(event, ...)
+
+  Emit an `event` with variable option args.
+
+### Emitter#listeners(event)
+
+  Return an array of callbacks, or an empty array.
+
+### Emitter#hasListeners(event)
+
+  Check if this emitter has `event` handlers.

+
+## Usage
+
+```js
+var Composer = require('composer');
+```
+
+## API
+
+### [.task](index.js#L62)
+
+Register a new task with it's options and dependencies.
+
+Dependencies may also be specified as a glob pattern. Be aware that

+  return app.src('templates/pages/*.hbs')
+    .pipe(app.dest('_gh_pages'));
+});
+```
+
+### [.build](index.js#L118)
+
+Build a task or array of tasks.

+});
+
+var fn = app.series('foo', function bar(done) {
+  console.log('this is bar');
+  done();
+});
+
+fn(function(err) {
+  if (err) return console.error(err);
+  console.log('done');
+});
+//=> this is foo
+//=> this is bar
+//=> done
+```
+
+### [.parallel](index.js#L217)
+
+Compose task or list of tasks into a single function that runs the tasks in parallel.
+

+  setTimeout(function() {
+    console.log('this is foo');
+    done();
+  }, 500);
+});
+
+var fn = app.parallel('foo', function bar(done) {
+  console.log('this is bar');
+  done();
+});
+
+fn(function(err) {
+  if (err) return console.error(err);
+  console.log('done');
+});
+//=> this is bar
+//=> this is foo
+//=> done
+```
+
+## Events
+
+[composer](https://github.com/doowb/composer) is an event emitter that may emit the following events:
+
+### starting
+
+This event is emitted when a `build` is starting.
+
+The event emits 2 arguments, the current instance of [composer](https://github.com/doowb/composer) as the `app` and an object containing the build runtime information.
+
+```js
+app.on('starting', function(app, build) {});
+```
+
+* `build` exposes a `.date` object that has a `.start` property containing the start time as a `Date` object.
+* `build` exposes a `.hr` object that has a `.start` property containing the start time as an `hrtime` array.
+
+### finished
+
+This event is emitted when a `build` has finished.
+
+The event emits 2 arguments, the current instance of [composer](https://github.com/doowb/composer) as the `app` and an object containing the build runtime information.
+
+```js
+app.on('finished', function(app, build) {});
+```
+
+* `build` exposes a `.date` object that has `.start` and `.end` properties containing start and end times of the build as `Date` objects.
+* `build` exposes a `.hr` object that has `.start`, `.end`, `.duration`, and `.diff` properties containing timing information calculated using `process.hrtime`
+
+### error
+
+This event is emitted when an error occurrs during a `build`.
+The event emits 1 argument as an `Error` object containing additional information about the build and the task running when the error occurred.
+
+```js
+app.on('error', function(err) {});
+```
+
+Additional properties:
+
+* `app`: current composer instance running the build
+* `build`: current build runtime information
+* `task`: current task instance running when the error occurred
+* `run`: current task runtime information
+
+### task:starting
+
+This event is emitted when a task is starting.
+The event emits 2 arguments, the current instance of the task object and an object containing the task runtime information.
+
+```js
+app.on('task:starting', function(task, run) {});
+```
+
+The `run` parameter exposes:
+
+* `.date` **{Object}**: has a `.start` property containing the start time as a `Date` object.
+* `.hr` **{Object}**: has a `.start` property containing the start time as an `hrtime` array.
+
+### task:finished
+
+This event is emitted when a task has finished.
+
+The event emits 2 arguments, the current instance of the task object and an object containing the task runtime information.
+
+```js
+app.on('task:finished', function(task, run) {});
+```
+
+The `run` parameter exposes:
+
+* `.date` **{Object}**: has a `.date` object that has `.start` and `.end` properties containing start and end times of the task as `Date` objects.
+* `run` **{Object}**: has an `.hr` object that has `.start`, `.end`, `.duration`, and `.diff` properties containing timing information calculated using `process.hrtime`
+
+### task:error
+
+This event is emitted when an error occurrs while running a task.
+The event emits 1 argument as an `Error` object containing additional information about the task running when the error occurred.
+
+```js
+app.on('task:error', function(err) {});
+```
+
+**Additional properties**
+
+* `task`: current task instance running when the error occurred
+* `run`: current task runtime information
+
+## History
+
+### v0.13.0
+
+* Skip tasks by setting the `options.skip` option to the name of the task or an array of task names.
+* Making additional `err` properties non-enumerable to cut down on error output.
+
+### v0.12.0
+
+* You can no longer get a task from the `.task()` method by passing only the name. Instead do `var task = app.tasks[name];`
+* Passing only a name and no dependencies to `.task()` will result in a `noop` task being created.
+* `options` may be passed to `.build()`, `.series()` and `.parallel()`
+* `options` passed to `.build()` will be merged onto task options before running the task.
+* Skip tasks by setting their `options.run` option to `false`.
+
+### v0.11.3
+
+* Allow passing es2015 javascript generator functions to `.task()`.
+
+### v0.11.2
+
+* Allow using glob patterns for task dependencies.
+
+### v0.11.0
+
+* **BREAKING CHANGE**: Removed `.watch()`. Watch functionality can be added to [base](https://github.com/node-base/base) applications using [base-watch](https://github.com/node-base/base-watch).
+
+### v0.10.0
+
+* Removes `session`.
+
+### v0.9.0
+
+* Use `default` when no tasks are passed to `.build()`.
+
+### v0.8.4
+
+* Ensure task dependencies are unique.
+
+### v0.8.2
+
+* Emitting `task` when adding a task through `.task()`
+* Returning task when calling `.task(name)` with only a name.
+
+### v0.8.0
+
+* Emitting `task:*` events instead of generic `*` events. See [event docs](#events) for more information.
+
+### v0.7.0
+
+* No longer returning the current task when `.task()` is called without a name.
+* Throwing an error when `.task()` is called without a name.
+
+### v0.6.0
+
+* Adding properties to `err` instances and emitting instead of emitting multiple parameters.
+* Adding series and parallel flows/methods.
+
+### v0.5.0
+
+* **BREAKING CHANGE** Renamed `.run()` to `.build()`
+
+### v0.4.2
+
+* `.watch` returns an instance of `FSWatcher`
+
+### v0.4.1
+
+* Currently running task returned when calling `.task()` without a name.
+
+### v0.4.0
+
+* Add session-cache to enable per-task data contexts.
+
+### v0.3.0
+
+* Event bubbling/emitting changed.
+
+### v0.1.0
+
+* Initial release.

+### v0.13.0
+
+- Skip tasks by setting the `options.skip` option to the name of the task or an array of task names.
+- Making additional `err` properties non-enumerable to cut down on error output.
+
+### v0.12.0
+
+- You can no longer get a task from the `.task()` method by passing only the name. Instead do `var task = app.tasks[name];`
+- Passing only a name and no dependencies to `.task()` will result in a `noop` task being created.
+- `options` may be passed to `.build()`, `.series()` and `.parallel()`
+- `options` passed to `.build()` will be merged onto task options before running the task.
+- Skip tasks by setting their `options.run` option to `false`.
+
+### v0.11.3
+
+- Allow passing es2015 javascript generator functions to `.task()`.
+
+### v0.11.2
+
+- Allow using glob patterns for task dependencies.
+
+### v0.11.0
+
+- **BREAKING CHANGE**: Removed `.watch()`. Watch functionality can be added to [base][] applications using [base-watch][].
+
+### v0.10.0
+
+- Removes `session`.
+
+### v0.9.0
+
+- Use `default` when no tasks are passed to `.build()`.
+
+### v0.8.4
+
+- Ensure task dependencies are unique.
+
+### v0.8.2
+
+- Emitting `task` when adding a task through `.task()`
+- Returning task when calling `.task(name)` with only a name.
+
+### v0.8.0
+
+- Emitting `task:*` events instead of generic `*` events. See [event docs](#events) for more information.
+
+### v0.7.0
+
+- No longer returning the current task when `.task()` is called without a name.
+- Throwing an error when `.task()` is called without a name.
+
+### v0.6.0
+
+- Adding properties to `err` instances and emitting instead of emitting multiple parameters.
+- Adding series and parallel flows/methods.
+
+### v0.5.0
+
+- **BREAKING CHANGE** Renamed `.run()` to `.build()`
+
+### v0.4.2
+
+- `.watch` returns an instance of `FSWatcher`
+
+### v0.4.1
+
+- Currently running task returned when calling `.task()` without a name.
+
+### v0.4.0
+
+- Add session-cache to enable per-task data contexts.
+
+### v0.3.0
+
+- Event bubbling/emitting changed.
+
+### v0.1.0
+
+- Initial release.

+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+[![build status](https://secure.travis-ci.org/substack/node-concat-map.png)](http://travis-ci.org/substack/node-concat-map)
+
+example
+=======
+
+``` js
+var concatMap = require('concat-map');
+var xs = [ 1, 2, 3, 4, 5, 6 ];
+var ys = concatMap(xs, function (x) {
+    return x % 2 ? [ x - 0.1, x, x + 0.1 ] : [];
+});
+console.dir(ys);
+```
+
+***
+
+```
+[ 0.9, 1, 1.1, 2.9, 3, 3.1, 4.9, 5, 5.1 ]
+```
+
+methods
+=======
+
+``` js
+var concatMap = require('concat-map')
+```
+
+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.
+
+install
+=======
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install concat-map
+```

+
+## API
+
+### fromObject(obj)
+
+Returns source map converter from given object.
+
+### fromJSON(json)
+
+Returns source map converter from given json string.
+
+### fromBase64(base64)
+
+Returns source map converter from given base64 encoded json string.
+
+### fromComment(comment)
+
+Returns source map converter from given base64 encoded json string prefixed with `//# sourceMappingURL=...`.
+
+### fromMapFileComment(comment, mapFileDir)
+
+Returns source map converter from given `filename` by parsing `//# sourceMappingURL=filename`.
+
+`filename` must point to a file that is found inside the `mapFileDir`. Most tools store this file right next to the
+generated file, i.e. the one containing the source map.
+
+### fromSource(source)
+
+Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was found.
+
+### fromMapFileSource(source, mapFileDir)
+
+Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was
+found.
+
+The sourcemap will be read from the map file found by parsing `# sourceMappingURL=file` comment. For more info see
+fromMapFileComment.
+
+### toObject()
+
+Returns a copy of the underlying source map.
+
+### toJSON([space])
+
+Converts source map to json string. If `space` is given (optional), this will be passed to
+[JSON.stringify](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify) when the
+JSON string is generated.
+
+### toBase64()
+
+Converts source map to base64 encoded json string.
+
+### toComment([options])
+
+Converts source map to an inline comment that can be appended to the source-file.
+
+By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would
+normally see in a JS source file.
+
+When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.
+
+### addProperty(key, value)
+
+Adds given property to the source map. Throws an error if property already exists.
+
+### setProperty(key, value)
+
+Sets given property to the source map. If property doesn't exist it is added, otherwise its value is updated.
+
+### getProperty(key)
+
+Gets given property of the source map.
+
+### removeComments(src)
+
+Returns `src` with all source map comments removed
+
+### removeMapFileComments(src)
+
+Returns `src` with all source map comments pointing to map files removed.
+
+### commentRegex
+
+Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments.
+
+### mapFileCommentRegex
+
+Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments pointing to map files.
+
+### generateMapFileComment(file, [options])
+
+Returns a comment that links to an external source map via `file`.
+
+By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would normally see in a JS source file.
+
+When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.

+
+> Basic object cache with `get`, `set`, `del`, and `has` methods for node.js/javascript projects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save cache-base
+```
+
+## Usage
+
+```js
+var Cache = require('cache-base');
+
+// instantiate
+var app = new Cache();
+
+// set values
+app.set('a', 'b');
+app.set('c.d', 'e');
+
+// get values
+app.get('a');
+//=> 'b'
+app.get('c');
+//=> {d: 'e'}
+
+console.log(app.cache);
+//=> {a: 'b'}
+```
+
+**Inherit**
+
+```js
+var util = require('util');
+var Cache = require('cache-base');
+
+function MyApp() {
+  Cache.call(this);
+}
+util.inherits(MyApp, Cache);
+
+var app = new MyApp();
+app.set('a', 'b');
+app.get('a');
+//=> 'b'
+```
+
+**Namespace**
+
+Define a custom property for storing values.
+
+```js
+var Cache = require('cache-base').namespace('data');
+var app = new Cache();
+app.set('a', 'b');
+console.log(app.data);
+//=> {a: 'b'}
+```
+
+## API
+
+### [namespace](index.js#L21)
+
+Create a `Cache` constructor that when instantiated will store values on the given `prop`.
+
+**Params**
+
+* `prop` **{String}**: The property name to use for storing values.
+* `returns` **{Function}**: Returns a custom `Cache` constructor
+
+**Example**
+
+```js
+var Cache = require('cache-base').namespace('data');
+var cache = new Cache();
+
+cache.set('foo', 'bar');
+//=> {data: {foo: 'bar'}}
+```
+
+### [Cache](index.js#L35)
+
+Create a new `Cache`. Internally the `Cache` constructor is created using the `namespace` function, with `cache` defined as the storage object.
+
+**Params**
+
+* `cache` **{Object}**: Optionally pass an object to initialize with.
+
+**Example**
+
+```js
+var app = new Cache();
+```
+
+### [.set](index.js#L76)
+
+Assign `value` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `set` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.on('set', function(key, val) {
+  // do something when `set` is emitted
+});
+
+app.set(key, value);
+
+// also takes an object or array
+app.set({name: 'Halle'});
+app.set([{foo: 'bar'}, {baz: 'quux'}]);
+console.log(app);
+//=> {name: 'Halle', foo: 'bar', baz: 'quux'}
+```
+
+### [.union](index.js#L106)
+
+Union `array` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+app.union('a.b', ['foo']);
+app.union('a.b', ['bar']);
+console.log(app.get('a'));
+//=> {b: ['foo', 'bar']}
+```
+
+### [.get](index.js#L136)
+
+Return the value of `key`. Dot notation may be used to get [nested property values](https://github.com/jonschlinkert/get-value).
+
+**Params**
+
+* `key` **{String}**: The name of the property to get. Dot-notation may be used.
+* `returns` **{any}**: Returns the value of `key`
+
+**Events**
+
+* `emits`: `get` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.set('a.b.c', 'd');
+app.get('a.b');
+//=> {c: 'd'}
+
+app.get(['a', 'b']);
+//=> {c: 'd'}
+```
+
+### [.has](index.js#L163)
+
+Return true if app has a stored value for `key`, false only if value is `undefined`.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{Boolean}**
+
+**Events**
+
+* `emits`: `has` with `key` and true or false as arguments.
+
+**Example**
+
+```js
+app.set('foo', 'bar');
+app.has('foo');
+//=> true
+```
+
+### [.del](index.js#L191)
+
+Delete one or more properties from the instance.
+
+**Params**
+
+* `key` **{String|Array}**: Property name or array of property names.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `del` with the `key` as the only argument.
+
+**Example**
+
+```js
+app.del(); // delete all
+// or
+app.del('foo');
+// or
+app.del(['foo', 'bar']);
+```
+
+### [.clear](index.js#L210)
+
+Reset the entire cache to an empty object.
+
+**Example**
+
+```js
+app.clear();
+```
+
+### [.visit](index.js#L227)
+
+Visit `method` over the properties in the given object, or map
+visit over the object-elements in an array.
+
+**Params**
+
+* `method` **{String}**: The name of the `base` method to call.
+* `val` **{Object|Array}**: The object or array to iterate over.
+* `returns` **{Object}**: Returns the instance for chaining.

+
+Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## Assign or Merge vs. Visit
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend`:
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. But **if you also want to emit an event** each time a property is added to the `data` object. A better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach, when an array is passed to `set`, `mapVisit` calls `set` on each object in the array. When an object is passed, `visit` calls `set` on each property in the object. As a result, the `data` event will be emitted every time a property is added to `data`.
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // some event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+> Delete nested properties from an object using dot notation.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save unset-value
+```
+
+## Usage
+
+```js
+var unset = require('unset-value');
+
+var obj = {a: {b: {c: 'd', e: 'f'}}};
+unset(obj, 'a.b.c');
+console.log(obj);
+//=> {a: {b: {e: 'f'}}};
+```
+
+## Examples
+
+### Updates the object when a property is deleted
+
+```js
+var obj = {a: 'b'};
+unset(obj, 'a');
+console.log(obj);
+//=> {}
+```
+
+### Returns true when a property is deleted
+
+```js
+unset({a: 'b'}, 'a') // true
+```
+
+### Returns `true` when a property does not exist
+
+This is consistent with `delete` behavior in that it does not
+throw when a property does not exist.
+
+```js
+unset({a: {b: {c: 'd'}}}, 'd') // true
+```
+
+### delete nested values
+
+```js
+var one = {a: {b: {c: 'd'}}};
+unset(one, 'a.b');
+console.log(one);
+//=> {a: {}}
+
+var two = {a: {b: {c: 'd'}}};
+unset(two, 'a.b.c');
+console.log(two);
+//=> {a: {b: {}}}
+
+var three = {a: {b: {c: 'd', e: 'f'}}};
+unset(three, 'a.b.c');
+console.log(three);
+//=> {a: {b: {e: 'f'}}}
+```
+
+### throws on invalid args
+
+```js
+unset();
+// 'expected an object.'
+```

+
+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+  If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Environment Variables
+
+  When running through Node.js, you can set a few environment variables that will
+  change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+  __Note:__ The environment variables beginning with `DEBUG_` end up being
+  converted into an Options object that gets used with `%o`/`%O` formatters.
+  See the Node.js documentation for
+  [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+  for the complete list.
+
+## Formatters
+
+
+  Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+### Custom formatters
+
+  You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+## Browser support
+  You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+  or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+  if you don't want to build it yourself.
+
+  Debug's enable state is currently persisted by `localStorage`.
+  Consider the situation shown below where you have `worker:a` and `worker:b`,
+  and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```

+
+> Bind a context to all functions in an object, including deeply nested functions.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install deep-bind --save
+```
+
+## Usage
+
+```js
+var deepBind = require('deep-bind');
+```
+
+**Example**
+
+Bind a context to an object of template helpers before passing them to an engine:
+
+```js
+var ctx = {
+  app: {views: {}},
+  context: {a: 'b'}
+};
+
+// pass the following to the template engine
+var helpers = deepBind({
+  foo: function() {
+    return this.context;
+  },
+  bar: function() {},
+  baz: function() {}
+}, ctx);
+```
+
+## API
+
+### [deepBind](index.js#L14)
+
+Bind a `thisArg` to all the functions on the target
+
+**Params**
+
+* `target` **{Object|Array}**: Object or Array with functions as values that will be bound.
+* `thisArg` **{Object}**: Object to bind to the functions
+* `returns` **{Object|Array}**: Object or Array with bound functions.
+

+## API
+
+### [defaultCompare](index.js#L16)
+
+Basic sort algorithm that has similar behavior to `Array.prototype.sort`
+for null and undefined, but also allows sorting by an object property.
+
+**Params**
+
+* `a` **{Mixed}**: First value to compare.
+* `b` **{Mixed}**: Second value to compare.
+* `prop` **{String}**: Optional property to use when comparing objects. If specified must be a string.
+* `returns` **{Number}**: Returns 1 when `a` should come after `b`, -1 when `a` should come before `b`, and 0 when `a` and `b` are equal.
+

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+Create regex for template delimiters.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save delimiter-regex
+```
+
+## Usage
+
+```js
+var delims = require('delimiter-regex');
+```
+
+**Example**:
+
+Get a regex for matching front-matter:
+
+```js
+delims('---', '---');
+//=> /---\s*([\s\S]*?)\s*---/
+```
+
+If no args are passed, es6 delimiter regex is returned:
+
+```js
+delims();
+//=> /\$\{\s*([\s\S]*?)\s*\}/
+```
+
+## Params
+
+* **delimiters** `{String|Array}`: supports array format (`delims([''])`) or list (`delims('')`)
+* **options**: currently RegExp `flags` is the only option
+
+**Flags example**
+
+```js
+delims('', {flags: 'gm'});
+//=> /\{\{([^}}]*)\}\}/gm

+[![build status][1]][2] [![dependency status][3]][4]
+
+[![browser support][5]][6]
+
+Creates a duplex stream
+
+Taken from [event-stream][7]
+
+## duplex (writeStream, readStream)
+
+Takes a writable stream and a readable stream and makes them appear as a readable writable stream.
+
+It is assumed that the two streams are connected to each other in some way.
+
+## Example
+
+```js
+var grep = cp.exec('grep Stream')
+
+duplex(grep.stdin, grep.stdout)
+```
+
+## Installation
+
+`npm install duplexer`
+
+## Tests
+
+`npm test`

+# duplexify
+
+Turn a writeable and readable stream into a single streams2 duplex stream.
+
+Similar to [duplexer2](https://github.com/deoxxa/duplexer2) except it supports both streams2 and streams1 as input
+and it allows you to set the readable and writable part asynchronously using `setReadable(stream)` and `setWritable(stream)`
+
+```
+npm install duplexify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/duplexify.svg?style=flat)](http://travis-ci.org/mafintosh/duplexify)
+
+## Usage
+
+Use `duplexify(writable, readable, streamOptions)` (or `duplexify.obj(writable, readable)` to create an object stream)
+
+``` js
+var duplexify = require('duplexify')
+
+// turn writableStream and readableStream into a single duplex stream
+var dup = duplexify(writableStream, readableStream)
+
+dup.write('hello world') // will write to writableStream
+dup.on('data', function(data) {
+  // will read from readableStream
+})
+```
+
+You can also set the readable and writable parts asynchronously
+
+``` js
+var dup = duplexify()
+
+dup.write('hello world') // write will buffer until the writable
+                         // part has been set
+
+// wait a bit ...
+dup.setReadable(readableStream)
+
+// maybe wait some more?
+dup.setWritable(writableStream)
+```
+
+If you call `setReadable` or `setWritable` multiple times it will unregister the previous readable/writable stream.
+To disable the readable or writable part call `setReadable` or `setWritable` with `null`.
+
+If the readable or writable streams emits an error or close it will destroy both streams and bubble up the event.
+You can also explicitly destroy the streams by calling `dup.destroy()`. The `destroy` method optionally takes an
+error object as argument, in which case the error is emitted as part of the `error` event.
+
+``` js
+dup.on('error', function(err) {
+  console.log('readable or writable emitted an error - close will follow')
+})
+
+dup.on('close', function() {
+  console.log('the duplex stream is destroyed')
+})
+
+dup.destroy() // calls destroy on the readable and writable part (if present)
+```
+
+## HTTP request example
+
+Turn a node core http request into a duplex stream is as easy as
+
+``` js
+var duplexify = require('duplexify')
+var http = require('http')
+
+var request = function(opts) {
+  var req = http.request(opts)
+  var dup = duplexify(req)
+  req.on('response', function(res) {
+    dup.setReadable(res)
+  })
+  return dup
+}
+
+var req = request({
+  method: 'GET',
+  host: 'www.google.com',
+  port: 80
+})
+
+req.end()
+req.pipe(process.stdout)
+```

+# empty-dir [![Build Status](https://secure.travis-ci.org/js-cli/js-empty-dir.svg?branch=master)](http://travis-ci.org/js-cli/js-empty-dir)
+> Check if a directory is empty.
+
+[![NPM](https://nodei.co/npm/empty-dir.png)](https://nodei.co/npm/empty-dir/)
+
+Note that directories with `.DS_Store` on mac are considered empty.
+
+## Example
+```js
+const emptyDir = require('empty-dir');
+
+emptyDir('./', function (err, result) {
+  if (err) {
+    console.error(err);
+  } else {
+    console.log('Directory is empty:', result);
+  }
+});
+
+var result = emptyDir.sync('./test/empty');
+console.log('Directory is empty:', result);
+```
+
+**Filter function**
+
+Both async and sync take a filter function as the second argument.
+
+_(This gives you the ability to eliminate files like `.DS_Store` on mac, or `Thumbs.db` on windows from causing the result to be "not empty" (`.DS_Store` is already filtered by default).)_
+
+```js
+const emptyDir = require('empty-dir');
+
+function filter(filepath) {
+  return !/Thumbs\.db$/i.test(filepath);
+}
+
+emptyDir('./', filter, function (err, result) {
+  if (err) {
+    console.error(err);
+  } else {
+    console.log('Directory is empty:', result);
+  }
+});
+
+var result = emptyDir.sync('./test/empty', filter);
+console.log('Directory is empty:', result);
+```
+
+## Release History
+
+* 2014-05-08 - v0.1.0 - initial release
+* 2016-02-07 - v0.2.0 - add filter support

+
+> Routing for static site generators, build systems and task runners, heavily based on express.js routes but works with file objects. Used by Assemble, Verb, and Template.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i en-route --save
+```
+
+## API
+
+### [Router](lib/index.js#L21)
+
+Initialize a new `Router` with the given `options`.
+
+**Params**
+
+* **{Object}**: options
+* `returns` **{Router}**: which is an callable function
+
+### [.param](lib/index.js#L78)
+
+Map the given param placeholder `name`(s) to the given callback.
+
+Parameter mapping is used to provide pre-conditions to routes
+which use normalized placeholders. For example a `:user_id` parameter
+could automatically load a user's information from the database without
+any additional code,
+The callback uses the same signature as middleware, the only difference
+being that the value of the placeholder is passed, in this case the _id_
+
+of the user. Once the `next()` function is invoked, just like middleware
+it will continue on to execute the route, or subsequent parameter functions.
+
+**Params**
+
+* `name` **{String}**
+* `fn` **{Function}**
+* `returns` **{Router}** `Object`: for chaining
+
+**Example**
+
+```js
+app.param('user_id', function(file, next, id) {
+  User.find(id, function(err, user) {
+    if (err) {
+      return next(err);
+    } else if (!user) {
+      return next(new Error('failed to load user'));
+    }
+    file.user = user;
+    next();
+  });
+});
+```
+
+### [.use](lib/index.js#L383)
+
+Use the given middleware function, with optional path, defaulting to `/`.
+
+The other difference is that _route_ path is stripped and not visible
+to the handler function. The main effect of this feature is that mounted
+handlers can operate without any code changes regardless of the `prefix`
+pathname.
+
+**Params**
+
+* `fn` **{Function}**
+
+**Example**
+
+```js
+var router = new Router();
+
+router.use(function(file, next) {
+  false.should.be.true;
+  next();
+});
+```
+
+### [.route](lib/index.js#L443)
+
+Create a new Route for the given path. Each route contains a separate middleware stack.

+
+**Params**
+
+* `path` **{String}**
+* `returns` **{Object}** `Route`: for chaining
+
+### [.method](lib/index.js#L470)
+
+Add additional methods to the current router instance.
+
+**Params**
+
+* `methods` **{String|Array}**: New methods to add to the router.
+* `returns` **{Object}**: the router to enable chaining
+
+**Example**
+
+```
+var router = new Router();
+router.method('post');
+router.post('.hbs', function(file, next) {
+  next();
+});
+```
+
+### [.all](lib/route.js#L108)
+
+Add a handler for all methods to this route.
+
+Behaves just like middleware and can respond or call `next`
+to continue processing.
+You can use multiple `.all` call to add multiple handlers.
+
+**Params**
+
+* `handler` **{Function}**
+* `returns` **{Object}** `Route`: for chaining
+
+**Example**
+
+```js
+function checkSomething(file, next) {
+  next();
+};
+
+function validateUser(file, next) {
+  next();
+};
+
+route
+  .all(validateUser)
+  .all(checkSomething)
+  .get(function(file, next) {
+    file.data.message = "Hello, World!";
+  });
+```

+ * The callback uses the same signature as middleware, the only difference

+ * it will continue on to execute the route, or subsequent parameter functions.
+ *
+ * **Example**
+ *
+ * ```js
+ * app.param('user_id', function(file, next, id) {
+ *   User.find(id, function(err, user) {
+ *     if (err) {

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+# end-of-stream
+
+A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
+
+	npm install end-of-stream
+
+[![Build status](https://travis-ci.org/mafintosh/end-of-stream.svg?branch=master)](https://travis-ci.org/mafintosh/end-of-stream)
+
+## Usage
+
+Simply pass a stream and a callback to the `eos`.
+Both legacy streams, streams2 and stream3 are supported.
+
+``` js
+var eos = require('end-of-stream');
+
+eos(readableStream, function(err) {
+  // this will be set to the stream instance
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended', this === readableStream);
+});
+
+eos(writableStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has finished', this === writableStream);
+});
+
+eos(duplexStream, function(err) {
+	if (err) return console.log('stream had an error or closed early');
+	console.log('stream has ended and finished', this === duplexStream);
+});
+

+
+> express.js inspired template-engine manager.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save engine-cache
+```
+
+## Usage
+
+```js
+var Engines = require('engine-cache');
+```
+
+## API
+
+### [Engines](index.js#L21)
+
+**Params**
+
+* `engines` **{Object}**: Optionally pass an object of engines to initialize with.
+
+**Example**
+
+```js
+var Engines = require('engine-cache');
+var engines = new Engines();
+```
+
+### [.setEngine](index.js#L43)
+
+Register the given view engine callback `fn` as `ext`.
+
+**Params**
+
+* `ext` **{String}**
+* `options` **{Object|Function}**: or callback `fn`.
+* `fn` **{Function}**: Callback.
+* `returns` **{Object}** `Engines`: to enable chaining.
+
+**Example**
+
+```js
+var consolidate = require('consolidate')
+engines.setEngine('hbs', consolidate.handlebars)
+```
+
+### [.setEngines](index.js#L74)
+
+Add an object of engines onto `engines.cache`.
+
+**Params**
+
+* `obj` **{Object}**: Engines to load.
+* `returns` **{Object}** `Engines`: to enable chaining.
+
+**Example**
+
+```js
+engines.setEngines(require('consolidate'))
+```
+
+### [.getEngine](index.js#L101)
+
+Return the engine stored by `ext`. If no `ext` is passed, undefined is returned.
+
+**Params**
+
+* `ext` **{String}**: The engine to get.
+* `returns` **{Object}**: The specified engine.
+
+**Example**
+
+```js
+var consolidate = require('consolidate');
+var engine = engine.setEngine('hbs', consolidate.handlebars);
+
+var engine = engine.getEngine('hbs');
+console.log(engine);
+// => {render: [function], renderFile: [function]}
+```
+
+### [.helpers](index.js#L132)
+
+Get and set helpers for the given `ext` (engine). If no `ext` is passed, the entire helper cache is returned.
+
+**Example:**
+
+See [helper-cache](https://github.com/jonschlinkert/helper-cache) for any related issues, API details, and documentation.
+
+**Params**
+
+* `ext` **{String}**: The helper cache to get and set to.
+* `returns` **{Object}**: Object of helpers for the specified engine.
+
+**Example**
+
+```js
+var helpers = engines.helpers('hbs');
+helpers.addHelper('bar', function() {});
+helpers.getEngineHelper('bar');
+helpers.getEngineHelper();
+```
+
+## Changelog
+
+**v0.19.0** ensure the string is only rendered once by passing the compiled function to the `render` method
+
+**v0.18.0** the `.load` method was renamed to `.setHelpers`
+
+**v0.16.0** the `.clear()` method was removed. A custom `inspect` method was added.
+
+**v0.15.0** `.getEngine()` no longer returns the entire `cache` object when `ext` is undefined.

+
+Template engine based on Lo-Dash template, but adds features like the ability to register helpers and more easily set data to be used as context in templates.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save engine
+```
+
+## Usage
+
+```js
+var Engine = require('engine');
+var engine = new Engine();
+
+engine.helper('upper', function(str) {
+  return str.toUpperCase();
+});
+
+engine.render('<%= upper(name) %>', {name: 'Brian'});
+//=> 'BRIAN'
+```
+
+## API
+
+### [Engine](index.js#L28)
+
+Create an instance of `Engine` with the given options.
+
+**Params**
+
+* `options` **{Object}**
+
+**Example**
+
+```js
+var Engine = require('engine');
+var engine = new Engine();
+
+// or
+var engine = require('engine')();
+```
+
+### [.helper](index.js#L82)
+
+Register a template helper.
+
+**Params**
+
+* `prop` **{String}**
+* `fn` **{Function}**
+* `returns` **{Object}**: Instance of `Engine` for chaining
+
+**Example**
+
+```js
+engine.helper('upper', function(str) {
+  return str.toUpperCase();
+});
+
+engine.render('<%= upper(user) %>', {user: 'doowb'});
+//=> 'DOOWB'
+```
+
+### [.helpers](index.js#L112)
+
+Register an object of template helpers.
+
+**Params**
+
+* `helpers` **{Object|Array}**: Object or array of helper objects.
+* `returns` **{Object}**: Instance of `Engine` for chaining
+
+**Example**
+
+```js
+engine.helpers({
+ upper: function(str) {
+   return str.toUpperCase();
+ },
+ lower: function(str) {
+   return str.toLowerCase();
+ }
+});
+
+// Or, just require in `template-helpers`
+engine.helpers(require('template-helpers')._);
+```
+
+### [.data](index.js#L131)
+
+Add data to be passed to templates as context.
+
+**Params**
+
+* `key` **{String|Object}**: Property key, or an object
+* `value` **{any}**: If key is a string, this can be any typeof value
+* `returns` **{Object}**: Engine instance, for chaining
+
+**Example**
+
+```js
+engine.data({first: 'Brian'});
+engine.render('<%= last %>, <%= first %>', {last: 'Woodward'});
+//=> 'Woodward, Brian'
+```
+
+### [.compile](index.js#L200)
+
+Creates a compiled template function that can interpolate data properties in "interpolate" delimiters, HTML-escape interpolated data properties in "escape" delimiters, and execute JavaScript in "evaluate" delimiters. Data properties may be accessed as free variables in the template. If a setting object is provided it takes precedence over `engine.settings` values.
+
+**Params**
+
+* `str` **{string}**: The template string.
+* `opts` **{Object}**: The options object.
+* `escape` **{RegExp}**: The HTML "escape" delimiter.
+* `evaluate` **{RegExp}**: The "evaluate" delimiter.
+* `imports` **{Object}**: An object to import into the template as free variables.
+* `interpolate` **{RegExp}**: The "interpolate" delimiter.
+* `sourceURL` **{string}**: The sourceURL of the template's compiled source.
+* `variable` **{string}**: The data object variable name.
+* `returns` **{Function}**: Returns the compiled template function.
+
+**Example**
+
+```js
+var fn = engine.compile('Hello, <%= user %>!');
+//=> [function]
+
+fn({user: 'doowb'});
+//=> 'Hello, doowb!'
+
+fn({user: 'halle'});
+//=> 'Hello, halle!'
+```
+
+### [.render](index.js#L317)
+
+Renders templates with the given data and returns a string.
+
+**Params**
+
+* `str` **{String}**
+* `data` **{Object}**
+* `returns` **{String}**
+
+**Example**
+
+```js
+engine.render('<%= user %>', {user: 'doowb'});
+//=> 'doowb'
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+# get-value [![NPM version](https://badge.fury.io/js/get-value.svg)](http://badge.fury.io/js/get-value)  [![Build Status](https://travis-ci.org/jonschlinkert/get-value.svg)](https://travis-ci.org/jonschlinkert/get-value)
+
+> Use property paths (`a.b.c`) to get a nested value from an object.
+
+**[Benchmarks](./benchmark)**
+
+This is 10x faster and more performant than [dot-prop](https://github.com/sindresorhus/dot-prop), and it passes all of the dot-prop tests.
+
+Of the libs benchmarked, _dot-prop was the least performant_:
+
+```bash
+#1: deep
+  get-value x 3,308,335 ops/sec ±1.32% (94 runs sampled)
+  dot-prop x 197,631 ops/sec ±1.27% (94 runs sampled)
+  getobject x 218,635 ops/sec ±1.51% (91 runs sampled)
+
+#2: shallow
+  get-value x 5,762,976 ops/sec ±1.21% (95 runs sampled)
+  dot-prop x 695,892 ops/sec ±1.42% (95 runs sampled)
+  getobject x 724,493 ops/sec ±1.46% (93 runs sampled)
+```
+
+Also, get-value supports escaping dots in paths, which is common when object keys are file paths with extensions, dot-prop does not.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i get-value --save
+```
+
+Install with [bower](http://bower.io/)
+
+```sh
+$ bower install get-value --save
+```
+
+## Usage
+
+```js
+var get = require('get-value');
+
+var obj = {a: {b : {c: {d: 'foo'}}}, e: [{f: 'g'}]};
+get(obj, 'a.b.c');
+//=> {d: 'foo'}
+
+get(obj, 'a.b.c.d');
+//=> 'foo'
+
+get(obj, 'e[0].f');
+//=> 'g'
+```
+
+**key as an array**
+
+Optionally pass the key as an array (this is useful when you need to dynamically build up the property name)
+
+```js
+var obj = {a: {b: 'c'}};
+get(obj, ['a', 'b']);
+//=> 'c'
+```
+

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## Assign or Merge vs. Visit
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend`:
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. But **if you also want to emit an event** each time a property is added to the `data` object. A better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach, when an array is passed to `set`, `mapVisit` calls `set` on each object in the array. When an object is passed, `visit` calls `set` on each property in the object. As a result, the `data` event will be emitted every time a property is added to `data`.
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // some event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](https://en.wikipedia.org/wiki/JavaScript)).
+Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/jquery/esprima/contributors).
+
+### Features
+
+- Full support for ECMAScript 2017 ([ECMA-262 8th Edition](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/es5.md) as standardized by [ESTree project](https://github.com/estree/estree)
+- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
+- Optional tracking of syntax node location (index-based and line-column)
+- [Heavily tested](http://esprima.org/test/ci.html) (~1500 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
+
+### API
+
+Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
+
+A simple example on Node.js REPL:
+
+```javascript
+> var esprima = require('esprima');
+> var program = 'const answer = 42';
+
+> esprima.tokenize(program);
+[ { type: 'Keyword', value: 'const' },
+  { type: 'Identifier', value: 'answer' },
+  { type: 'Punctuator', value: '=' },
+  { type: 'Numeric', value: '42' } ]
+  
+> esprima.parseScript(program);
+{ type: 'Program',
+  body:
+   [ { type: 'VariableDeclaration',
+       declarations: [Object],
+       kind: 'const' } ],
+  sourceType: 'script' }
+```
+
+For more information, please read the [complete documentation](http://esprima.org/doc).

+# exit-hook [![Build Status](https://travis-ci.org/sindresorhus/exit-hook.svg?branch=master)](https://travis-ci.org/sindresorhus/exit-hook)
+
+> Run some code when the process exits
+
+The `process.on('exit')` event doesn't catch all the ways a process can exit.
+
+Useful for cleaning up.
+
+
+## Install
+
+```sh
+$ npm install --save exit-hook
+```
+
+
+## Usage
+
+```js
+var exitHook = require('exit-hook');
+
+exitHook(function () {
+	console.log('exiting');
+});
+
+// you can add multiple hooks, even across files
+exitHook(function () {
+	console.log('exiting 2');
+});
+
+throw new Error('unicorns');
+
+//=> exiting
+//=> exiting 2
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+
+> Expand POSIX bracket expressions (character classes) in glob patterns.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install expand-brackets --save
+```
+
+## Usage
+
+```js
+var brackets = require('expand-brackets');
+
+brackets('[![:lower:]]');
+//=> '[^a-z]'
+```
+
+## .isMatch
+
+Return true if the given string matches the bracket expression:
+
+```js
+brackets.isMatch('A', '[![:lower:]]');
+//=> true
+
+brackets.isMatch('a', '[![:lower:]]');
+//=> false
+```
+
+## .makeRe
+
+Make a regular expression from a bracket expression:
+
+```js
+brackets.makeRe('[![:lower:]]');
+//=> /[^a-z]/
+```
+
+The following named POSIX bracket expressions are supported:
+
+* `[:alnum:]`: Alphanumeric characters (`a-zA-Z0-9]`)
+* `[:alpha:]`: Alphabetic characters (`a-zA-Z]`)
+* `[:blank:]`: Space and tab (`[ t]`)
+* `[:digit:]`: Digits (`[0-9]`)
+* `[:lower:]`: Lowercase letters (`[a-z]`)
+* `[:punct:]`: Punctuation and symbols. (`[!"#$%&'()*+, -./:;<=>?@ [\]^_``{|}~]`)
+* `[:upper:]`: Uppercase letters (`[A-Z]`)
+* `[:word:]`: Word characters (letters, numbers and underscores) (`[A-Za-z0-9_]`)
+* `[:xdigit:]`: Hexadecimal digits (`[A-Fa-f0-9]`)
+
+Collating sequences are not supported.

+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i expand-object --save
+```
+
+Also see [collapse-object](https://github.com/jonschlinkert/collapse-object), for doing the reverse of this library.
+
+**Examples**
+
+```js
+expand('a')
+//=> {a: ''}
+
+expand('a.b')
+//=> {a: {b: ''}}
+
+expand('a|b')
+//=> {a: '', b: ''}
+
+expand('a|b', {toBoolean: true})
+//=> {a: true, b: true}
+
+expand('a:b')
+//=> {a: 'b'}
+
+expand('a,b')
+//=> ['a', 'b']
+```
+
+### Type casting
+
+Introduced in v0.2.2, some values are cast to their JavaScript type.
+
+**Booleans**
+
+If the value is `"true"` or `"false"` it will be coerced to a boolean value.
+
+```js
+expand('a:true')
+//=> {a: true}
+expand('a:false')
+//=> {a: false}
+```
+
+**Numbers**
+
+If the value is an integer it will be coerced to a number.
+
+```js
+expand('a:1')
+//=> {a: 1}
+expand('a:123')
+//=> {a: 123}
+```
+
+**Regex**
+
+If the value is a simple regular expression it will be coerced to a `new RegExp()`.
+
+```js
+expand('a:/foo/')
+//=> {a: /foo/}
+expand('a.b.c:/^bar/gmi')
+//=> {a: {b: {c: /^bar/gmi}}}
+```
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i expand-object --save
+```
+
+## CLI
+
+Usage with cli:
+
+```sh
+❯ expand-object --help
+
+  Usage: expand-object [options] <string>
+
+  Expand a string into a JavaScript object using a simple notation.
+
+  Options:
+
+    -h, --help     output usage information
+    -V, --version  output the version number
+    -r, --raw      Output as raw javascript object - not stringified
+
+  Examples:
+
+    $ expand-object "a:b"
+    $ expand-object --raw "a:b"
+    $ echo "a:b" | expand-object
+```
+
+## node.js
+
+To use as a node.js library:
+
+```js
+var expand = require('expand-object');
+```
+
+### children
+
+> Expand dots into **child objects**:
+
+```js
+expand('a')
+//=> {a: ''}
+expand('a.b')
+//=> {a: {b: ''}}
+expand('a.b.c')
+//=> {a: {b: {c: ''}}}
+expand('a.b.c.d')
+//=> {a: {b: {c: {d: ''}}}}
+```
+
+### siblings
+
+expand-object supports two kinds of siblings, **general** and **adjacent**. It's much easier to understand the difference in the last example.
+
+#### general siblings
+
+> Use pipes (`|`) to expand **general siblings**:
+
+```js
+expand('a|b')
+//=> {a: '', b: ''}
+expand('a|b|c')
+//=> {a: '', b: '', c: ''}
+expand('a|b|c|d')
+//=> {a: '', b: '', c: '', d: ''}
+expand('a:b|c:d')
+//=> {a: 'b', c: 'd'}
+```
+
+#### adjacent siblings
+
+> Use plus (`+`) to expand **adjacent siblings**:
+
+Adjacent siblings are objects that immediately follow one another.
+
+```js
+expand('a:b+c:d')
+//=> {a: 'b', c: 'd'}
+expand('a.b:c+d:e')
+//=> {a: {b: 'c', d: 'e'}}
+```
+
+#### difference between sibling types
+
+In the example below:
+
+* **general**: `d` is a sibling to `a`
+* **adjacent**: `d` is a sibling to `b`
+
+```js
+// general siblings
+expand('a.b:c|d:e')
+//=> { a: { b: 'c' }, d: 'e' }
+
+// adjacent siblings
+expand('a.b:c+d:e')
+//=> { a: { b: 'c', d: 'e' } }
+```
+
+### key-value pairs
+
+> Expand colons into **key-value pairs**:
+
+```js
+expand('a:b')
+//=> {a: 'b'}
+expand('a.b:c')
+//=> {a: {b: 'c'}}
+expand('a.b.c:d')
+//=> {a: {b: {c: 'd'}}}
+```
+
+### arrays
+
+> Expand comma separated values into **arrays**:
+
+```js
+expand('a,b')
+//=> ['a', 'b']
+expand('a,b,c')
+//=> ['a', 'b', 'c']
+expand('a:b,c,d|e:f,g,h')
+//=> {a: ['b', 'c', 'd'], e: ['f', 'g', 'h']}
+```
+
+## Usage examples
+
+Expand siblings with comma separated values into arrays:
+
+```js
+expand('a:b,c,d|e:f,g,h')
+//=> {a: ['b', 'c', 'd'], e: ['f', 'g', 'h']}
+```
+
+Expand children with comma separated values into arrays:
+
+```js
+expand('a.b.c:d,e,f|g.h:i,j,k')
+//=> {a: { b: {c: ['d', 'e', 'f']}}, g: {h: ['i', 'j', 'k']}}
+```
+
+Expand sibling objects into key-value pairs:
+
+```js
+expand('a:b|c:d')
+//=> {a: 'b', c: 'd'}
+expand('a:b|c:d|e:f')
+//=> {a: 'b', c: 'd', e: 'f'}
+expand('a:b|c:d|e:f|g:h')
+//=> {a: 'b', c: 'd', e: 'f', g: 'h'}
+```
+
+Expand child objects into key-value pairs:
+
+```js
+expand('a.b:c')
+//=> {a: {b: 'c'}}
+expand('a.b.c:d')
+//=> {a: {b: {c: 'd'}}}
+expand('a.b.c.d:e')
+//=> {a: {b: {c: {d: 'e'}}}}
+```
+
+Expand sibling and child objects into key-value pairs:
+
+```js
+expand('a:b|c:d')
+//=> {a: 'b', c: 'd'}
+expand('a.b.c|d.e:f')
+//=> {a: {b: {c: ''}}, d: {e: 'f'}}
+expand('a.b:c|d.e:f')
+//=> {a: {b: 'c'}, d: {e: 'f'}}
+expand('a.b.c:d|e.f.g:h')
+//=> {a: {b: {c: 'd'}}, e: {f: {g: 'h'}}}
+```

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+
+> Parse string values in package.json into objects.
+
+You might also be interested in [normalize-pkg](https://github.com/jonschlinkert/normalize-pkg).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save expand-pkg
+```
+
+## Usage
+
+```js
+var Config = require('./');
+var config = new Config();
+console.log(config.expand(require('./package')));
+```
+
+## Schema
+
+Values are parsed using a [schema](lib/schema.js) that is passed to [map-schema](https://github.com/jonschlinkert/map-schema) (builds on the schema from [normalize-pkg](https://github.com/jonschlinkert/normalize-pkg) as a starting point):
+
+* only properties that have a corresponding field on the schema will be parsed.
+* any properties that do not have a corresponding field are returned unmodified.
+
+See the [.field docs](#field) to learn how to add or overwrite a field on the schema.
+
+## Defaults
+
+A `default` value may optionally be defined when a `.field` is registered. When `.expand` is run and a property that is required or recommended by npm is missing, `expand-pkg` attempts to create the field if valid data can be found in the repository.
+
+The following fields are the only built-in fields with default values:
+
+* `version`: `'0.1.0'`
+* `license`: `'MIT'`
+* `engines`: `{node: '>= 0.10.0'}`
+
+## API
+
+### [Config](index.js#L24)
+
+Create an instance of `Config` with the given `options`.
+
+**Example**
+
+```js
+var config = new Config();
+var pkg = config.expand({
+  author: 'Jon Schlinkert (https://github.com/jonschlinkert)'
+});
+console.log(pkg);
+//=> {name: 'Jon Schlinkert', url: 'https://github.com/jonschlinkert'}
+```
+
+**Params**
+
+* `options` **{Object}**
+
+### [.field](index.js#L70)
+
+Add a field to the schema, or overwrite or extend an existing field. The last argument is an `options` object that supports the following properties:
+
+* `normalize` **{Function}**: function to be called on the given package.json value when the `.expand` method is called
+* `default` **{any}**: default value to be used when the package.json property is undefined.
+* `required` **{Boolean}**: define `true` if the property is required
+
+**Example**
+
+```js
+var config = new Config();
+
+config.field('foo', 'string', {
+  default: 'bar'
+});
+
+var pkg = config.expand({});
+console.log(pkg);
+//=> {foo:  'bar'}
+```
+
+**Params**
+
+* `name` **{String}**: Field name (required)
+* `type` **{String|Array}**: One or more native javascript types allowed for the property value (required)
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the instance
+
+### [.expand](index.js#L96)
+
+Iterate over `pkg` properties and expand values that have corresponding [fields](#field) registered on the schema.
+
+**Example**
+
+```js
+var config = new Config();
+var pkg = config.expand(require('./package.json'));
+```
+
+**Params**
+
+* `pkg` **{Object}**: The `package.json` object to expand
+* `options` **{Object}**
+* `returns` **{Object}**: Returns an expanded package.json object.
+
+## Options
+
+### options.knownOnly
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Omit properties from package.json that do not have a field registered on the schema.
+
+```js
+var Config = require('expand-pkg');
+var config = new Config({knownOnly: true});
+
+console.log(config.expand({author: 'Brian Woodward', foo: 'bar'}));
+//=> {author: {name: 'Brian Woodward'}}
+```
+
+### options.pick
+
+**Type**: `array`
+
+**Default**: `undefined`
+
+Filter the resulting object to contain only the specified keys.
+
+### options.omit
+
+**Type**: `array`
+
+**Default**: `undefined`
+
+Remove the specified keys from the resulting object.
+
+### options.fields
+
+Pass a `fields` object on the options to customize any fields on the schema (also see [options.extend](#options-extend)):
+
+```js
+var pkg = config.expand(require('./package'), {
+  extend: true,
+  fields: {
+    name: {
+      normalize: function() {
+        return 'bar'
+      }
+    }
+  }
+});
+
+console.log(pkg.name);
+//=> 'bar'
+```
+
+### options.extend
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Used with [options.field](#options-field), pass `true` if you want to extend a field that is already defined on the schema.
+
+```js
+var pkg = config.expand(require('./package'), {
+  extend: true,
+  fields: {
+    name: {
+      normalize: function() {
+        return 'bar'
+      }
+    }
+  }
+});
+
+console.log(pkg.name);
+//=> 'bar'
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# expand-range [![NPM version](https://img.shields.io/npm/v/expand-range.svg?style=flat)](https://www.npmjs.com/package/expand-range) [![NPM downloads](https://img.shields.io/npm/dm/expand-range.svg?style=flat)](https://npmjs.org/package/expand-range) [![Build Status](https://img.shields.io/travis/jonschlinkert/expand-range.svg?style=flat)](https://travis-ci.org/jonschlinkert/expand-range)
+
+Fast, bash-like range expansion. Expand a range of numbers or letters, uppercase or lowercase. See the benchmarks. Used by micromatch.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install expand-range --save
+```
+
+Wraps [fill-range] to do range expansion using `..` separated strings. See [fill-range] for the full list of options and features.
+
+## Example usage
+
+```js
+var expand = require('expand-range');
+```
+
+**Params**
+
+```js
+expand(start, stop, increment);
+```
+
+* `start`: the number or letter to start with
+* `end`: the number or letter to end with
+* `increment`: optionally pass the increment to use. works for letters or numbers
+
+**Examples**
+
+```js
+expand('a..e')
+//=> ['a', 'b', 'c', 'd', 'e']
+
+expand('a..e..2')
+//=> ['a', 'c', 'e']
+
+expand('A..E..2')
+//=> ['A', 'C', 'E']
+
+expand('1..3')
+//=> ['1', '2', '3']
+
+expand('0..-5')
+//=> [ '0', '-1', '-2', '-3', '-4', '-5' ]
+
+expand('-9..9..3')
+//=> [ '-9', '-6', '-3', '0', '3', '6', '9' ])
+
+expand('-1..-10..-2')
+//=> [ '-1', '-3', '-5', '-7', '-9' ]
+
+expand('1..10..2')
+//=> [ '1', '3', '5', '7', '9' ]
+```
+
+### Custom function
+
+Optionally pass a custom function as the second argument:
+
+```js
+expand('a..e', function (val, isNumber, pad, i) {
+  if (!isNumber) {
+    return String.fromCharCode(val) + i;
+  }
+  return val;
+});
+//=> ['a0', 'b1', 'c2', 'd3', 'e4']
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i export-files --save
+```
+
+## Usage
+
+Specify the directory with files to export:
+
+```js
+module.exports = require('export-files')(__dirname);
+//=> {a: [function], b: [function], c: [function]}
+```
+
+## Changes
+
+**v0.2.0 - breaking changes**
+
+* Non-javascript files are no longer handled. That functionality was moved to [to-exports](https://github.com/jonschlinkert/to-exports). This decision was made to keep this lib as fast as possible.
+* This library no longer takes any arguments besides the directory to read.

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+# extend() for Node.js <sup>[![Version Badge][npm-version-png]][npm-url]</sup>
+
+`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
+
+Notes:
+
+* Since Node.js >= 4,
+  [`Object.assign`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
+  now offers the same functionality natively (but without the "deep copy" option).
+  See [ECMAScript 2015 (ES6) in Node.js](https://nodejs.org/en/docs/es6).
+* Some native implementations of `Object.assign` in both Node.js and many
+  browsers (since NPM modules are for the browser too) may not be fully
+  spec-compliant.
+  Check [`object.assign`](https://www.npmjs.com/package/object.assign) module for
+  a compliant candidate.
+
+## Installation
+
+This package is available on [npm][npm-url] as: `extend`
+
+``` sh
+npm install extend
+```
+
+## Usage
+
+**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
+
+*Extend one object with one or more others, returning the modified object.*
+
+**Example:**
+
+``` js
+var extend = require('extend');
+extend(targetObject, object1, object2);
+```
+
+Keep in mind that the target object will be modified, and will be returned from extend().
+
+If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
+Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
+Warning: passing `false` as the first argument is not supported.
+
+### Arguments
+
+* `deep` *Boolean* (optional)
+If set, the merge becomes recursive (i.e. deep copy).
+* `target`	*Object*
+The object to extend.
+* `object1`	*Object*
+The object that will be merged into the first.
+* `objectN` *Object* (Optional)
+More objects to merge into the first.

+# extglob [![NPM version](https://badge.fury.io/js/extglob.svg)](http://badge.fury.io/js/extglob)  [![Build Status](https://travis-ci.org/jonschlinkert/extglob.svg)](https://travis-ci.org/jonschlinkert/extglob)
+
+> Convert extended globs to regex-compatible strings. Add (almost) the expressive power of regular expressions to glob patterns.
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i extglob --save
+```
+
+Used by [micromatch](https://github.com/jonschlinkert/micromatch).
+
+**Features**
+
+* Convert an extglob string to a regex-compatible string. **Only converts extglobs**, to handle full globs use [micromatch](https://github.com/jonschlinkert/micromatch).
+* Pass `{regex: true}` to return a regex
+* Handles nested patterns
+* More complete (and correct) support than [minimatch](https://github.com/isaacs/minimatch)
+
+## Usage
+
+```js
+var extglob = require('extglob');
+
+extglob('?(z)');
+//=> '(?:z)?'
+extglob('*(z)');
+//=> '(?:z)*'
+extglob('+(z)');
+//=> '(?:z)+'
+extglob('@(z)');
+//=> '(?:z)'
+extglob('!(z)');
+//=> '(?!^(?:(?!z)[^/]*?)).*$'
+```
+
+**Optionally return regex**
+
+```js
+extglob('!(z)', {regex: true});
+//=> /(?!^(?:(?!z)[^/]*?)).*$/
+```
+
+## Extglob patterns
+
+To learn more about how extglobs work, see the docs for [Bash pattern matching](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html):
+
+* `?(pattern)`: Match zero or one occurrence of the given pattern.
+* `*(pattern)`: Match zero or more occurrences of the given pattern.
+* `+(pattern)`: Match one or more occurrences of the given pattern.
+* `@(pattern)`: Match one of the given pattern.
+* `!(pattern)`: Match anything except one of the given pattern.

+# falsey [![NPM version](https://img.shields.io/npm/v/falsey.svg?style=flat)](https://www.npmjs.com/package/falsey) [![NPM monthly downloads](https://img.shields.io/npm/dm/falsey.svg?style=flat)](https://npmjs.org/package/falsey)  [![NPM total downloads](https://img.shields.io/npm/dt/falsey.svg?style=flat)](https://npmjs.org/package/falsey) [![Linux Build Status](https://img.shields.io/travis/jonschlinkert/falsey.svg?style=flat&label=Travis)](https://travis-ci.org/jonschlinkert/falsey) [![Windows Build Status](https://img.shields.io/appveyor/ci/jonschlinkert/falsey.svg?style=flat&label=AppVeyor)](https://ci.appveyor.com/project/jonschlinkert/falsey)
+
+> Returns true if `value` is falsey. Works for strings, arrays and `arguments` objects with a length of `0`, and objects with no own enumerable properties are considered falsey.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save falsey
+```
+
+What makes this lib unique (and fun) is the option to pass an array of values that should always evuate as "falsey".
+
+This is useful for CLI prompts, web forms, etc. For example, you might want to allow users to define `nil` or `nope` to disable something.
+
+## Usage
+
+```js
+var isFalsey = require('falsey');
+
+console.log(isFalsey('nil');
+//=> `true`
+```
+
+## Examples
+
+All of the following return `true`
+
+```js
+isFalsey(undefined);
+isFalsey(null);
+isFalsey(false);
+isFalsey(0);
+isFalsey('');
+isFalsey(NaN);
+isFalsey({});
+isFalsey([]);
+```
+
+All of the following return `false`:
+
+```js
+isFalsey('foo');
+isFalsey(true);
+isFalsey(50);
+isFalsey('10');
+isFalsey({a: 'b'});
+isFalsey([0]);
+```
+
+### Special cases
+
+There are several additional "falsey" words built in, but these can be overridden or turned off by passing a value as the second argument.
+
+**Built-in additional falsey keywords**
+
+* `none`
+* `nil`
+* `nope`
+* `no`
+* `nada`
+* `0`
+* `false`
+
+**Disable additions**
+
+```js
+isFalsey('nil', []);
+//=> false
+```
+
+**Customize additions**
+
+Pass one or more keywords that should return `true` when evaluated as _falsey_:
+
+```js
+isFalsey('zilch', ['no', 'nope', 'nada', 'zilch']);
+//=> true
+```
+
+**Extend additions**
+
+Built-in keywords are exposed on the `.keywords` property. These can be used to extend the defaults:
+
+```js
+isFalsey('zilch', isFalsey.keywords.concat(['zilch']));
+//=> true
+```

+# file-contents [![NPM version](https://badge.fury.io/js/file-contents.svg)](http://badge.fury.io/js/file-contents)
+
+> Set the `contents` property on a file object. Abstraction from vinyl-fs to support stream or non-stream usage.
+
+This is inspired by the code in [vinyl-fs](http://github.com/wearefractal/vinyl-fs) `src`. I needed a function that essentially did the same thing but could be used with stream or non-stream code.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i file-contents --save
+```
+
+## Usage
+
+```js
+var through = require('through2');
+var contents = require('file-contents');
+
+function toStream(fp) {
+  var stream = through.obj();
+  stream.write({path: fp});
+  stream.end();
+  return stream;
+}
+
+toStream('README.md')
+  .pipe(contents())
+  .on('data', function (file) {
+    console.log(file.contents.toString());
+  });
+```
+
+**async**
+
+An `.async()` method is exposed for non-stream, async usage.
+
+```js
+contents.async({path: 'README.md'}, function (err, file) {
+  // results in something like:
+  // 
+  //   { path: 'README.md',
+  //   stat:
+  //    { dev: 16777218,
+  //      mode: 33188,
+  //      nlink: 1,
+  //      uid: 501,
+  //      gid: 20,
+  //      rdev: 0,
+  //      blksize: 4096,
+  //      ino: 26436116,
+  //      size: 2443,
+  //      blocks: 8,
+  //      atime: Fri Jul 17 2015 03:01:54 GMT-0400 (EDT),
+  //      mtime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+  //      ctime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+  //      birthtime: Tue Jul 14 2015 23:03:58 GMT-0400 (EDT) },
+  // contents: <Buffer 23 20 66 69 6c 65 2d 63 6f 6e 74 65 6e 74 73 20 5b 21 5b 4e 50 4d 20 76 65 72 73 69 6f 6e 5d 28 68 74 74 70 73 3a 2f 2f 62 61 64 67 65 2e 66 75 72 79 ... > }
+});
+```
+
+**sync**
+
+A `.sync()` method is exposed for non-stream, sync usage.
+
+```js
+var file = contents.sync({path: 'README.md'});
+// results in something like:
+// 
+//   { path: 'README.md',
+//   stat:
+//    { dev: 16777218,
+//      mode: 33188,
+//      nlink: 1,
+//      uid: 501,
+//      gid: 20,
+//      rdev: 0,
+//      blksize: 4096,
+//      ino: 26436116,
+//      size: 2443,
+//      blocks: 8,
+//      atime: Fri Jul 17 2015 03:01:54 GMT-0400 (EDT),
+//      mtime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+//      ctime: Wed Jul 15 2015 02:46:55 GMT-0400 (EDT),
+//      birthtime: Tue Jul 14 2015 23:03:58 GMT-0400 (EDT) },
+// contents: <Buffer 23 20 66 69 6c 65 2d 63 6f 6e 74 65 6e 74 73 20 5b 21 5b 4e 50 4d 20 76 65 72 73 69 6f 6e 5d 28 68 74 74 70 73 3a 2f 2f 62 61 64 67 65 2e 66 75 72 79 ... > }
+```
+

+# lazy-cache [![NPM version](https://img.shields.io/npm/v/lazy-cache.svg)](https://www.npmjs.com/package/lazy-cache) [![Build Status](https://img.shields.io/travis/jonschlinkert/lazy-cache.svg)](https://travis-ci.org/jonschlinkert/lazy-cache)
+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+```sh
+$ npm i -d && npm test
+```

+> Returns true if a file is binary. Checks the actual contents, since extensions are not reliable. Basic wrapper for isbinaryfile to support vinyl files.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save file-is-binary
+```
+
+## Usage
+
+Uses [isbinaryfile](https://github.com/gjtorikian/isBinaryFile) to check the file contents and return
+
+```js
+var isBinary = require('file-is-binary');
+
+var file = new File({path: 'foo.gif', contents: fs.readFileSync('foo.gif')});
+console.log(isBinary(file));
+
+var file = new File({path: 'bar.txt', contents: fs.readFileSync('bar.txt')});
+console.log(isBinary(file));
+//=> false
+```

+# file-stat [![NPM version](https://badge.fury.io/js/file-stat.svg)](http://badge.fury.io/js/file-stat)
+
+> Set the `stat` property on a file object. Abstraction from vinyl-fs to support stream or non-stream usage.
+
+This is inspired by the `file.stat` code in [vinyl-fs](http://github.com/wearefractal/vinyl-fs). I needed a function that essentially did the same thing but could be used with stream or non-stream code.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i file-stat --save
+```
+
+## Usage
+
+```js
+var through = require('through2');
+var stats = require('file-stat');
+
+function toStream(fp) {
+  var stream = through.obj();
+  stream.write({path: fp});
+  stream.end();
+  return stream;
+}
+

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save fill-range
+```
+
+## Usage
+
+```js
+var range = require('fill-range');
+
+range('a', 'e');
+//=> ['a', 'b', 'c', 'd', 'e']
+```
+
+**Params**
+
+```js
+range(start, stop, step, options, fn);
+```
+
+* `start`: **{String|Number}** the number or letter to start with
+* `end`: **{String|Number}** the number or letter to end with
+* `step`: **{String|Number}** optionally pass the step to use. works for letters or numbers.
+* `options`: **{Object}**:
+  - `makeRe`: return a regex-compatible string (still returned as an array for consistency)
+  - `step`: pass the step on the options as an alternative to passing it as an argument
+  - `silent`: `true` by default, set to false to throw errors for invalid ranges.
+* `fn`: **{Function}** optionally [pass a function](#custom-function) to modify each character
+
+**Examples**
+
+```js
+range(1, 3)
+//=> ['1', '2', '3']
+
+range('1', '3')
+//=> ['1', '2', '3']
+
+range('0', '-5')
+//=> [ '0', '-1', '-2', '-3', '-4', '-5' ]
+
+range(-9, 9, 3)
+//=> [ '-9', '-6', '-3', '0', '3', '6', '9' ])
+
+range('-1', '-10', '-2')
+//=> [ '-1', '-3', '-5', '-7', '-9' ]
+
+range('1', '10', '2')
+//=> [ '1', '3', '5', '7', '9' ]
+
+range('a', 'e')
+//=> ['a', 'b', 'c', 'd', 'e']
+
+range('a', 'e', 2)
+//=> ['a', 'c', 'e']
+
+range('A', 'E', 2)
+//=> ['A', 'C', 'E']
+```
+
+### Invalid ranges
+
+When an invalid range is passed, `null` is returned.
+
+```js
+range('1.1', '2');
+//=> null
+
+range('a', '2');
+//=> null
+
+range(1, 10, 'foo');
+//=> null
+```
+
+If you want errors to be throw, pass `silent: false` on the options:
+
+### Custom function
+
+Optionally pass a custom function as the third or fourth argument:
+
+```js
+range('a', 'e', function (val, isNumber, pad, i) {
+  if (!isNumber) {
+    return String.fromCharCode(val) + i;
+  }
+  return val;
+});
+//=> ['a0', 'b1', 'c2', 'd3', 'e4']
+```
+
+### Special characters
+
+A special character may be passed as the third arg instead of a step increment. These characters can be pretty useful for brace expansion, creating file paths, test fixtures and similar use case.
+
+```js
+range('a', 'z', SPECIAL_CHARACTER_HERE);
+```
+
+**Supported characters**
+
+* `+`: repeat the given string `n` times
+* `|`: create a regex-ready string, instead of an array
+* `>`: join values to single array element
+* `?`: randomize the given pattern using [randomatic]
+
+#### plus
+
+Character: _(`+`)_
+
+Repeat the first argument the number of times passed on the second argument.
+
+**Examples:**
+
+```js
+range('a', 3, '+');
+//=> ['a', 'a', 'a']
+
+range('abc', 2, '+');
+//=> ['abc', 'abc']
+```
+
+#### pipe and tilde
+
+Characters: _(`|` and `~`)_
+
+Creates a regex-capable string (either a logical `or` or a character class) from the expanded arguments.
+
+**Examples:**
+
+```js
+range('a', 'c', '|');
+//=> ['(a|b|c)'
+
+range('a', 'c', '~');
+//=> ['[a-c]'
+
+range('a', 'z', '|5');
+//=> ['(a|f|k|p|u|z)'
+```
+
+**Automatic separator correction**
+
+To avoid this error:
+
+> `Range out of order in character class`
+
+Fill-range detects invalid sequences and uses the correct syntax. For example:
+
+**invalid** (regex)
+
+If you pass these:
+
+```js
+range('a', 'z', '~5');
+// which would result in this
+//=> ['[a-f-k-p-u-z]']
+
+range('10', '20', '~');
+// which would result in this
+//=> ['[10-20]']
+```
+
+**valid** (regex)
+
+fill-range corrects them to this:
+
+```js
+range('a', 'z', '~5');
+//=> ['(a|f|k|p|u|z)'
+
+range('10', '20', '~');
+//=> ['(10-20)'
+```
+
+#### angle bracket
+
+Character: _(`>`)_
+
+Joins all values in the returned array to a single value.
+
+**Examples:**
+
+```js
+range('a', 'e', '>');
+//=> ['abcde']
+
+range('5', '8', '>');
+//=> ['5678']
+
+range('2', '20', '2>');
+//=> ['2468101214161820']
+```
+
+#### question mark
+
+Character: _(`?`)_
+
+Uses [randomatic] to generate randomized alpha, numeric, or alpha-numeric patterns based on the provided arguments.
+
+**Examples:**
+
+_(actual results would obviously be randomized)_
+
+Generate a 5-character, uppercase, alphabetical string:
+
+```js
+range('A', 5, '?');
+//=> ['NSHAK']
+```
+
+Generate a 5-digit random number:
+
+```js
+range('0', 5, '?');
+//=> ['36583']
+```
+
+Generate a 10-character alpha-numeric string:
+
+```js
+range('A0', 10, '?');
+//=> ['5YJD60VQNN']
+```
+
+See the [randomatic] repo for all available options and or to create issues or feature requests related to randomization.

+# first-chunk-stream [![Build Status](https://travis-ci.org/sindresorhus/first-chunk-stream.svg?branch=master)](https://travis-ci.org/sindresorhus/first-chunk-stream)
+
+> Transform the first chunk in a stream
+
+Useful if you want to do something to the first chunk.
+
+You can also set the minimum size of that chunk.
+
+
+## Install
+
+```sh
+$ npm install --save first-chunk-stream
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var concat = require('concat-stream');
+var firstChunk = require('first-chunk-stream');
+
+// unicorn.txt => unicorn rainbow
+// `highWaterMark: 1` means it will only read 1 byte at the time
+fs.createReadStream('unicorn.txt', {highWaterMark: 1})
+	.pipe(firstChunk({minSize: 7}, function (chunk, enc, cb) {
+		this.push(chunk.toUpperCase());
+		cb();
+	}))
+	.pipe(concat(function (data) {
+		console.log(data);
+		//=> UNICORN rainbow
+	}));
+```
+
+
+## API
+
+### firstChunk([options], transform)
+
+#### options.minSize
+
+Type: `number`
+
+The minimum size of the first chunk.
+
+#### transform(chunk, encoding, callback)
+
+*Required*  
+Type: `function`
+
+The [function](http://nodejs.org/docs/latest/api/stream.html#stream_transform_transform_chunk_encoding_callback) that gets the first chunk.
+
+### firstChunk.ctor()
+
+Instead of returning a [stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform_1) instance, `firstChunk.ctor()` returns a constructor for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.

+
+```sh
+$ npm install fs-exists-sync --save
+```
+
+## Usage
+
+```js
+var exists = require('fs-exists-sync');
+
+console.log(exists('.'));
+//=> true
+console.log(exists(process.cwd()));
+//=> true
+console.log(exists('README.md'));
+//=> true
+console.log(exists('foo.txt'));
+//=> false
+console.log(exists(''));
+//=> false
+console.log(exists());
+//=> false
+```
+
+## Why another "exists" lib?
+
+I just want a _simple replacement for `fs.existsSync`_. Here is what I found:
+
+- [path-exists][]: Has dependencies to support a promises API
+- [fs-exists][]: async only
+- [file-exists][]: returns `false` if the path exists but is a directory.
+- [exists][]: nothing to do with `fs`.

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+# get-stdin [![Build Status](https://travis-ci.org/sindresorhus/get-stdin.svg?branch=master)](https://travis-ci.org/sindresorhus/get-stdin)
+
+> Get [stdin](https://nodejs.org/api/process.html#process_process_stdin) as a string or buffer
+
+
+## Install
+
+```
+$ npm install --save get-stdin
+```
+
+
+## Usage
+
+```js
+// example.js
+const getStdin = require('get-stdin');
+
+getStdin().then(str => {
+	console.log(str);
+	//=> 'unicorns'
+});
+```
+
+```
+$ echo unicorns | node example.js
+unicorns
+```
+
+
+## API
+
+Both methods returns a promise that is resolved when the `end` event fires on the `stdin` stream, indicating that there is no more data to be read.
+
+### getStdin()
+
+Get `stdin` as a string.
+
+In a TTY context, a promise that resolves to an empty string is returned.
+
+### getStdin.buffer()
+
+Get `stdin` as a buffer.
+
+In a TTY context, a promise that resolves to an empty buffer is returned.

+
+> Utility for getting an assemble view from a collection object.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save get-view
+```
+
+## Usage
+
+Should work with any collection of vinyl files.
+
+```js
+var getView = require('get-view');
+```
+
+**[templates](https://github.com/jonschlinkert/templates) example**
+
+Given the following setup code, all of the below examples would return a `page` from the `app.views.pages` collection:
+
+```js
+var templates = require('templates');
+app = templates();
+app.create('page');
+
+app.page('foo', {content: 'this is foo'});
+app.page('bar.md', {content: 'this is bar'});
+app.page('a/b/c/baz.md', {content: 'this is baz', base: 'a'});
+app.page('test/fixtures/templates/a.tmpl');
+```
+
+Get a view by customizing the lookup key with a function:
+
+```js
+var view = getView('foo.md', app.views.pages, function(key) {
+  return path.basename(key, path.extname(key));
+});
+
+//=> <Page "foo" <Buffer 74 68 69 73 20 69>>
+```
+
+Get a view by `view.path`
+
+```js
+var view = getView('a/b/c/baz.md', app.views.pages);
+//=> <Page "b/c/baz.md" <Buffer 74 68 69 73>>
+```
+
+Get a view by `view.basename`
+
+```js
+var view = getView('baz.md', app.views.pages);
+//=> <Page "b/c/baz.md" <Buffer 74 68 69 73>>
+```
+
+Get a view by `view.filename`
+
+```js
+var view = getView('baz', app.views.pages);
+//=> <Page "b/c/baz.md" <Buffer 74 68 69 73>>
+```
+
+Get a view by `view.relative`
+
+```js
+var view = getView('b/c/baz.md', app.views.pages);
+//=> <Page "b/c/baz.md" <Buffer 74 68 69 73>>
+```

+> Resolve the path to the user's local or global .gitconfig.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save git-config-path
+```
+
+## Usage
+
+Automatically gets the nearest `.git` config path, starting with the current working directory, then looking in the user's `home` directory.
+
+```js
+var gitConfigPath = require('git-config-path')();
+//=> '/Users/jonschlinkert/dev/git-config-path/.git/config'
+```
+
+To force `git-config-path` to only look for a global config path, pass `global`:
+
+```js
+var gitConfigPath = require('git-config-path')('global');
+//=> '/Users/jonschlinkert/.gitconfig'
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+
+> Returns an object with the (non-glob) base path and the actual pattern.
+
+Use [glob-parent](https://github.com/es128/glob-parent) if you just want the base path.
+
+## Install with [npm](npmjs.org)
+
+```bash

+```
+
+## Related projects
+* [glob-parent](https://github.com/es128/glob-parent): Strips glob magic from a string to provide the parent path
+* [micromatch](https://github.com/jonschlinkert/micromatch): Glob matching for javascript/node.js. A faster alternative to minimatch (10-45x faster on avg), with all the features you're used to using in your Grunt and gulp tasks.
+* [parse-glob](https://github.com/jonschlinkert/parse-glob): Parse a glob pattern into an object of tokens.
+* [is-glob](https://github.com/jonschlinkert/is-glob): Returns `true` if the given string looks like a glob pattern.
+* [braces](https://github.com/jonschlinkert/braces): Fastest brace expansion for node.js, with the most complete support for the Bash 4.3 braces specification.
+* [fill-range](https://github.com/jonschlinkert/fill-range): Fill in a range of numbers or letters, optionally passing an increment or multiplier to use.
+* [expand-range](https://github.com/jonschlinkert/expand-range): Fast, bash-like range expansion. Expand a range of numbers or letters, uppercase or lowercase. See the benchmarks. Used by micromatch.

+# is-glob [![NPM version](https://badge.fury.io/js/is-glob.svg)](http://badge.fury.io/js/is-glob)  [![Build Status](https://travis-ci.org/jonschlinkert/is-glob.svg)](https://travis-ci.org/jonschlinkert/is-glob)
+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+glob-parent [![Build Status](https://travis-ci.org/es128/glob-parent.svg)](https://travis-ci.org/es128/glob-parent) [![Coverage Status](https://img.shields.io/coveralls/es128/glob-parent.svg)](https://coveralls.io/r/es128/glob-parent?branch=master)
+======
+Javascript module to extract the non-magic parent path from a glob string.
+
+[![NPM](https://nodei.co/npm/glob-parent.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/glob-parent/)
+[![NPM](https://nodei.co/npm-dl/glob-parent.png?height=3&months=9)](https://nodei.co/npm-dl/glob-parent/)
+
+Usage
+-----
+```sh
+npm install glob-parent --save
+```
+
+**Examples**
+
+```js
+var globParent = require('glob-parent');
+
+globParent('path/to/*.js'); // 'path/to'
+globParent('/root/path/to/*.js'); // '/root/path/to'
+globParent('/*.js'); // '/'
+globParent('*.js'); // '.'
+globParent('**/*.js'); // '.'
+globParent('path/{to,from}'); // 'path'
+globParent('path/!(to|from)'); // 'path'
+globParent('path/?(to|from)'); // 'path'
+globParent('path/+(to|from)'); // 'path'
+globParent('path/*(to|from)'); // 'path'
+globParent('path/@(to|from)'); // 'path'
+globParent('path/**/*'); // 'path'
+
+// if provided a non-glob path, returns the nearest dir
+globParent('path/foo/bar.js'); // 'path/foo'
+globParent('path/foo/'); // 'path/foo'
+globParent('path/foo'); // 'path' (see issue #3 for details)
+```
+
+## Escaping
+
+The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
+
+- `?` (question mark)
+- `*` (star)
+- `|` (pipe)
+- `(` (opening parenthesis)
+- `)` (closing parenthesis)
+- `{` (opening curly brace)
+- `}` (closing curly brace)
+- `[` (opening bracket)
+- `]` (closing bracket)
+
+**Example**
+
+```js
+globParent('foo/[bar]/') // 'foo'
+globParent('foo/\\[bar]/') // 'foo/[bar]'
+```
+
+## Limitations
+
+#### Braces & Brackets
+This library attempts a quick and imperfect method of determining which path
+parts have glob magic without fully parsing/lexing the pattern. There are some
+advanced use cases that can trip it up, such as nested braces where the outer
+pair is escaped and the inner one contains a path separator. If you find
+yourself in the unlikely circumstance of being affected by this or need to
+ensure higher-fidelity glob handling in your library, it is recommended that you
+pre-process your input with [expand-braces] and/or [expand-brackets].
+
+#### Windows
+Backslashes are not valid path separators for globs. If a path with backslashes
+is provided anyway, for simple cases, glob-parent will replace the path
+separator for you and return the non-glob parent path (now with
+forward-slashes, which are still valid as Windows path separators).
+
+This cannot be used in conjunction with escape characters.
+
+```js
+// BAD
+globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)'
+
+// GOOD
+globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)'
+```
+
+If you are using escape characters for a pattern without path parts (i.e.
+relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
+
+```js
+// BAD
+globParent('foo \\[bar]') // 'foo '
+globParent('foo \\[bar]*') // 'foo '
+
+// GOOD
+globParent('./foo \\[bar]') // 'foo [bar]'
+globParent('./foo \\[bar]*') // '.'
+```

+
+[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Gitter chat][gitter-image]][gitter-url]
+
+A wrapper around [node-glob][node-glob-url] to make it streamy.
+
+## Usage
+
+```javascript
+var gs = require('glob-stream');
+
+var stream = gs.create('./files/**/*.coffee', { /* options */ });
+
+stream.on('data', function(file){
+  // file has path, base, and cwd attrs
+});
+```
+
+You can pass any combination of globs. One caveat is that you can not only pass a glob negation, you must give it at least one positive glob so it knows where to start. All given must match for the file to be returned.
+
+## API
+
+### create(globs, options)
+
+Returns a stream for multiple globs or filters.
+
+### createStream(positiveGlob, negativeGlobs, options)
+
+Returns a stream for a single glob or filter.
+
+### Options
+
+- cwd
+  - Default is `process.cwd()`
+- base
+  - Default is everything before a glob starts (see [glob-parent][glob-parent-url])
+- cwdbase
+  - Default is `false`
+  - When true it is the same as saying opt.base = opt.cwd
+- allowEmpty
+  - Default is `false`
+  - If true, won't emit an error when a glob pointing at a single file fails to match
+- Any through2 related options are documented in [through2][through2-url]
+
+This argument is passed directly to [node-glob][node-glob-url] so check there for more options
+
+### Glob
+
+```js
+var stream = gs.create(['./**/*.js', '!./node_modules/**/*']);
+```
+
+Globs are executed in order, so negations should follow positive globs. For example:
+
+```js
+gulp.src(['!b*.js', '*.js'])
+```
+
+would not exclude any files, but this would
+
+```js
+gulp.src(['*.js', '!b*.js'])
+```

+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+# through2
+
+[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
+
+**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
+
+Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
+
+Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
+
+```js
+fs.createReadStream('ex.txt')
+  .pipe(through2(function (chunk, enc, callback) {
+    for (var i = 0; i < chunk.length; i++)
+      if (chunk[i] == 97)
+        chunk[i] = 122 // swap 'a' for 'z'
+
+    this.push(chunk)
+
+    callback()
+   }))
+  .pipe(fs.createWriteStream('out.txt'))
+```
+
+Or object streams:
+
+```js
+var all = []
+
+fs.createReadStream('data.csv')
+  .pipe(csv2())
+  .pipe(through2.obj(function (chunk, enc, callback) {
+    var data = {
+        name    : chunk[0]
+      , address : chunk[3]
+      , phone   : chunk[10]
+    }
+    this.push(data)
+
+    callback()
+  }))
+  .on('data', function (data) {
+    all.push(data)
+  })
+  .on('end', function () {
+    doSomethingSpecial(all)
+  })
+```
+
+Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
+
+## API
+
+<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
+
+Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
+
+### options
+
+The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
+
+The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2({ objectMode: true, allowHalfOpen: false },
+    function (chunk, enc, cb) {
+      cb(null, 'wut?') // note we can use the second argument on the callback
+                       // to provide data as an alternative to this.push('wut?')
+    }
+  )
+  .pipe(fs.createWriteStream('/tmp/wut.txt'))
+```
+
+### transformFunction
+
+The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
+
+To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
+
+Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
+
+If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
+
+### flushFunction
+
+The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2(
+    function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop
+    function (cb) { // flush function
+      this.push('tacking on an extra buffer to the end');
+      cb();
+    }
+  ))
+  .pipe(fs.createWriteStream('/tmp/wut.txt'));
+```
+
+<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
+
+Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
+
+```js
+var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
+  if (record.temp != null && record.unit = "F") {
+    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
+    record.unit = "C"
+  }
+  this.push(record)
+  callback()
+})
+
+// Create instances of FToC like so:
+var converter = new FToC()
+// Or:
+var converter = FToC()
+// Or specify/override options when you instantiate, if you prefer:
+var converter = FToC({objectMode: true})
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](oh-my-glob.gif)
+
+## Usage
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Negation
+
+The intent for negation would be for a pattern starting with `!` to
+match everything that *doesn't* match the supplied pattern.  However,
+the implementation is weird, and for the time being, this should be
+avoided.  The behavior is deprecated in version 5, and will be removed
+entirely in version 6.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` {String} Pattern to be matched
+* `options` {Object}
+* `cb` {Function}
+  * `err` {Error | null}
+  * `matches` {Array<String>} filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` {String} Pattern to be matched
+* `options` {Object}
+* return: {Array<String>} filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` {String} pattern to search for
+* `options` {Object}
+* `cb` {Function} Called when an error occurs, or matches are found
+  * `err` {Error | null}
+  * `matches` {Array<String>} filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'DIR'` - Path exists, and is not a directory
+  * `'FILE'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the matched.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of patterns to exclude matches.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `nonegate` Suppress deprecated `negate` behavior.  (See below.)
+  Default=true
+* `nocomment` Suppress deprecated `comment` behavior.  (See below.)
+  Default=true
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+**Note**: In version 5 of this module, negation and comments are
+**disabled** by default.  You can explicitly set `nonegate:false` or
+`nocomment:false` to re-enable them.  They are going away entirely in
+version 6.
+
+The intent for negation would be for a pattern starting with `!` to
+match everything that *doesn't* match the supplied pattern.  However,
+the implementation is weird.  It is better to use the `ignore` option
+to set a pattern or set of patterns to exclude from matches.  If you
+want the "everything except *x*" type of behavior, you can use `**` as
+the main pattern, and set an `ignore` for the things to exclude.
+
+The comments feature is added in minimatch, primarily to more easily
+support use cases like ignore files, where a `#` at the start of a
+line makes the pattern "empty".  However, in the context of a
+straightforward filesystem globber, "comments" don't make much sense.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.
+

+> Get the npm global path prefix.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save global-prefix
+```
+
+This is partially based on the code used by npm internally to resolve the global prefix.
+
+## Usage
+
+```js
+var prefix = require('global-prefix');
+//=> '/usr/local' (this path will differ by system and user-defined config)
+```

+# graceful-fs
+
+graceful-fs functions as a drop-in replacement for the fs module,
+making various improvements.
+
+The improvements are meant to normalize behavior across different
+platforms and environments, and to make filesystem access more
+resilient to errors.
+
+## Improvements over [fs module](https://nodejs.org/api/fs.html)
+
+* Queues up `open` and `readdir` calls, and retries them once
+  something closes if there is an EMFILE error from too many file
+  descriptors.
+* fixes `lchmod` for Node versions prior to 0.6.2.
+* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
+* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
+  `lchown` if the user isn't root.
+* makes `lchmod` and `lchown` become noops, if not available.
+* retries reading a file if `read` results in EAGAIN error.
+
+On Windows, it retries renaming a file for up to one second if `EACCESS`
+or `EPERM` error occurs, likely because antivirus software has locked
+the directory.
+
+## USAGE
+
+```javascript
+// use just like fs
+var fs = require('graceful-fs')
+
+// now go and do stuff with it...
+fs.readFileSync('some-file-or-whatever')
+```
+
+## Global Patching
+
+If you want to patch the global fs module (or any other fs-like
+module) you can do this:
+
+```javascript
+// Make sure to read the caveat below.
+var realFs = require('fs')
+var gracefulFs = require('graceful-fs')
+gracefulFs.gracefulify(realFs)
+```
+
+This should only ever be done at the top-level application layer, in
+order to delay on EMFILE errors from any fs-using dependencies.  You
+should **not** do this in a library, because it can cause unexpected
+delays in other parts of the program.
+
+## Changes
+
+This module is fairly stable at this point, and used by a lot of
+things.  That being said, because it implements a subtle behavior
+change in a core part of the node API, even modest changes can be
+extremely breaking, and the versioning is thus biased towards
+bumping the major when in doubt.
+
+The main change between major versions has been switching between
+providing a fully-patched `fs` module vs monkey-patching the node core
+builtin, and the approach by which a non-monkey-patched `fs` was
+created.
+
+The goal is to trade `EMFILE` errors for slower fs operations.  So, if
+you try to open a zillion files, rather than crashing, `open`
+operations will be queued up and wait for something else to `close`.
+
+There are advantages to each approach.  Monkey-patching the fs means
+that no `EMFILE` errors can possibly occur anywhere in your
+application, because everything is using the same core `fs` module,
+which is patched.  However, it can also obviously cause undesirable
+side-effects, especially if the module is loaded multiple times.
+
+Implementing a separate-but-identical patched `fs` module is more
+surgical (and doesn't run the risk of patching multiple times), but
+also imposes the challenge of keeping in sync with the core module.
+
+The current approach loads the `fs` module, and then creates a
+lookalike object that has all the same methods, except a few that are
+patched.  It is safe to use in all versions of Node from 0.8 through
+7.0.
+
+### v4
+
+* Do not monkey-patch the fs module.  This module may now be used as a
+  drop-in dep, and users can opt into monkey-patching the fs builtin
+  if their app requires it.
+
+### v3
+
+* Monkey-patch fs, because the eval approach no longer works on recent
+  node.
+* fixed possible type-error throw if rename fails on windows
+* verify that we *never* get EMFILE errors
+* Ignore ENOSYS from chmod/chown
+* clarify that graceful-fs must be used as a drop-in
+
+### v2.1.0
+
+* Use eval rather than monkey-patching fs.
+* readdir: Always sort the results
+* win32: requeue a file if error has an OK status
+
+### v2.0
+
+* A return to monkey patching
+* wrap process.cwd
+
+### v1.1
+
+* wrap readFile
+* Wrap fs.writeFile.
+* readdir protection
+* Don't clobber the fs builtin
+* Handle fs.read EAGAIN errors by trying again
+* Expose the curOpen counter
+* No-op lchown/lchmod if not implemented
+* fs.rename patch only for win32
+* Patch fs.rename to handle AV software on Windows
+* Close #4 Chown should not fail on einval or eperm if non-root
+* Fix isaacs/fstream#1 Only wrap fs one time
+* Fix #3 Start at 1024 max files, then back off on EMFILE
+* lutimes that doens't blow up on Linux
+* A full on-rewrite using a queue instead of just swallowing the EMFILE error
+* Wrap Read/Write streams as well
+
+### 1.0
+
+* Update engines for node 0.6
+* Be lstat-graceful on Windows
+* first

+# gray-matter [![NPM version](https://img.shields.io/npm/v/gray-matter.svg?style=flat)](https://www.npmjs.com/package/gray-matter) [![NPM monthly downloads](https://img.shields.io/npm/dm/gray-matter.svg?style=flat)](https://npmjs.org/package/gray-matter) [![NPM total downloads](https://img.shields.io/npm/dt/gray-matter.svg?style=flat)](https://npmjs.org/package/gray-matter) [![Linux Build Status](https://img.shields.io/travis/jonschlinkert/gray-matter.svg?style=flat&label=Travis)](https://travis-ci.org/jonschlinkert/gray-matter)
+
+> Parse front-matter from a string or file. Fast, reliable and easy to use. Parses YAML front matter by default, but also has support for YAML, JSON, TOML or Coffee Front-Matter, with options to set custom delimiters. Used by metalsmith, assemble, verb and many other projects.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save gray-matter
+```
+
+## Heads up!
+
+Please see the [changelog](CHANGELOG.md) to learn about breaking changes that were made in v3.0.
+
+## What does this do?
+
+<details>
+<summary><strong>Run this example</strong></summary>
+
+Add the HTML in the following example to `example.html`, then add the following code to `example.js` and run `$ node example` (without the `$`):
+
+```js
+var fs = require('fs');
+var matter = require('gray-matter');
+var str = fs.readFileSync('example.html', 'utf8');
+console.log(matter(str));
+```
+
+</details>
+
+Converts a string with front-matter, like this:
+
+```handlebars
+---
+title: Hello
+slug: home
+---
+<h1>Hello world!</h1>
+```
+
+Into an object like this:
+
+```js
+{
+  content: '<h1>Hello world!</h1>',
+  data: { 
+    title: 'Hello', 
+    slug: 'home' 
+  }
+}
+```
+
+## Why use gray-matter?
+
+* **simple**: main function takes a string and returns an object
+* **accurate**: better at catching and handling edge cases than front-matter parsers that rely on regex for parsing
+* **fast**: faster than other front-matter parsers that use regex for parsing
+* **flexible**: By default, gray-matter is capable of parsing [YAML](https://github.com/nodeca/js-yaml), [JSON](http://en.wikipedia.org/wiki/Json) and JavaScript front-matter. But other [engines](#optionsengines) may be added.
+* **extensible**: Use [custom delimiters](#optionsdelimiters), or add support for [any language](#optionsengines), like [TOML](http://github.com/mojombo/toml), [CoffeeScript](http://coffeescript.org), or [CSON](https://github.com/bevry/cson)
+* **battle-tested**: used by [assemble](https://github.com/assemble/assemble), [metalsmith](https://github.com/segmentio/metalsmith), [phenomic](https://github.com/phenomic/phenomic), [verb](https://github.com/assemble/verb), [generate](https://github.com/generate/generate), [update](https://github.com/update/update) and many others.
+
+<details>
+<summary><strong>Rationale</strong></summary>
+
+**Why did we create gray-matter in the first place?**
+
+We created gray-matter after trying out other libraries that failed to meet our standards and requirements.
+
+Some libraries met most of the requirements, but _none met all of them_.
+
+**Here are the most important**:
+
+* Be usable, if not simple
+* Use a dependable and well-supported library for parsing YAML
+* Support other languages besides YAML
+* Support stringifying back to YAML or another language
+* Don't fail when no content exists
+* Don't fail when no front matter exists
+* Don't use regex for parsing. This is a relatively simple parsing operation, and regex is the slowest and most error-prone way to do it.
+* Have no problem reading YAML files directly
+* Have no problem with complex content, including **non-front-matter** fenced code blocks that contain examples of YAML front matter. Other parsers fail on this.
+* Support stringifying back to front-matter. This is useful for linting, updating properties, etc.
+* Allow custom delimiters, when it's necessary for avoiding delimiter collision.
+* Should return an object with at least these three properties (for debugging):
+  - `data`: the parsed YAML front matter, as a JSON object
+  - `content`: the contents as a string, without the front matter
+  - `orig`: the "original" content
+
+</details>
+
+## Usage
+
+Using Node's `require()` system:
+
+```js
+var matter = require('gray-matter');
+```
+
+Or with [typescript](https://www.typescriptlang.org)
+
+```js
+import matter = require('gray-matter');
+// OR
+import * as matter from 'gray-matter';
+```
+
+Pass a string and [options](#options) to gray-matter:
+
+```js
+console.log(matter('---\ntitle: Front Matter\n---\nThis is content.'));
+```
+
+Returns:
+
+```js
+{
+  content: '\nThis is content.',
+  data: { 
+    title: 'Front Matter' 
+  } 
+}
+```
+
+More about the returned object in the following section.
+
+***
+
+## Returned object
+
+gray-matter returns a `file` object with the following properties.
+
+**Enumerable**
+
+* `file.data` **{Object}**: the object created by parsing front-matter
+* `file.content` **{String}**: the input string, with `matter` stripped
+* `file.excerpt` **{String}**: an excerpt, if [defined on the options](#optionsexcerpt)
+
+**Non-enumerable**
+
+In addition, the following non-enumberable properties are added to the object to help with debugging.
+
+* `file.orig` **{Buffer}**: the original input string (or buffer)
+* `file.language` **{String}**: the front-matter language that was parsed. `yaml` is the default
+* `file.matter` **{String}**: the _raw_, un-parsed front-matter string
+* `file.stringify` **{Function}**: [stringify](#stringify) the file by converting `file.data` to a string in the given language, wrapping it in delimiters and appending it to `file.content`.
+
+## Run the examples
+
+If you'd like to test-drive the examples, first clone gray-matter into `my-project` (or wherever you want):
+
+```sh
+$ git clone https://github.com/jonschlinkert/gray-matter my-project
+```
+
+CD into `my-project` and install dependencies:
+
+```sh
+$ cd my-project && npm install
+```
+
+Then run any of the [examples](./examples) to see how gray-matter works:
+
+```sh
+$ node examples/<example_name>
+```

+
+## API
+
+### [matter](index.js#L30)
+
+Takes a string or object with `content` property, extracts and parses front-matter from the string, then returns an object with `data`, `content` and other [useful properties](#returned-object).
+
+**Params**
+
+* `input` **{Object|String}**: String, or object with `content` string
+* `options` **{Object}**
+* `returns` **{Object}**
+
+**Example**
+
+```js
+var matter = require('gray-matter');
+console.log(matter('---\ntitle: Home\n---\nOther stuff'));
+//=> { data: { title: 'Home'}, content: 'Other stuff' }
+```
+
+### [.stringify](index.js#L140)
+
+Stringify an object to YAML or the specified language, and append it to the given string. By default, only YAML and JSON can be stringified. See the [engines](#engines) section to learn how to stringify other languages.
+
+**Params**
+
+* `file` **{String|Object}**: The content string to append to stringified front-matter, or a file object with `file.content` string.
+* `data` **{Object}**: Front matter to stringify.
+* `options` **{Object}**: [Options](#options) to pass to gray-matter and [js-yaml](https://github.com/nodeca/js-yaml).
+* `returns` **{String}**: Returns a string created by wrapping stringified yaml with delimiters, and appending that to the given string.
+
+**Example**
+
+```js
+console.log(matter.stringify('foo bar baz', {title: 'Home'}));
+// results in:
+// ---
+// title: Home
+// ---
+// foo bar baz
+```
+
+### [.read](index.js#L160)
+
+Synchronously read a file from the file system and parse front matter. Returns the same object as the [main function](#matter).
+
+**Params**
+
+* `filepath` **{String}**: file path of the file to read.
+* `options` **{Object}**: [Options](#options) to pass to gray-matter.
+* `returns` **{Object}**: Returns [an object](#returned-object) with `data` and `content`
+
+**Example**
+
+```js
+var file = matter.read('./content/blog-post.md');
+```
+
+### [.test](index.js#L175)
+
+Returns true if the given `string` has front matter.
+
+**Params**
+
+* `string` **{String}**
+* `options` **{Object}**
+* `returns` **{Boolean}**: True if front matter exists.
+
+## Options
+
+### options.excerpt
+
+**Type**: `Object`
+
+**Default**: `undefined`
+
+Extract an excerpt that directly follows front-matter, or is the first thing in the string if no front-matter exists.
+
+**Example**
+
+```js
+var str = '--\ntitle: Home\n---\nAn excerpt\n---\nOther stuff';
+console.log(matter(str, {excerpt: true}));
+```
+
+Results in:
+
+```js
+{ 
+  data: { title: 'Home'}, 
+  excerpt: '\nAn excerpt', 
+  content: '\nAn excerpt\n---\nOther stuff' 
+}
+```
+
+### options.excerpt_separator
+
+**Type**: `String`
+
+**Default**: `undefined`
+
+Define a custom separator to use for excerpts.
+
+```js
+console.log(matter(string, {excerpt_separator: '<!-- end -->'}));
+```
+
+**Example**
+
+The following HTML string:
+
+```html
+---
+title: Blog
+---
+My awesome blog.
+<!-- end -->
+<h1>Hello world</h1>
+```
+
+Results in:
+
+```js
+{ 
+  data: { title: 'Blog'}, 
+  excerpt: 'My awesome blog.', 
+  content: 'My awesome blog.\n<!-- end -->\n<h1>Hello world</h1>' 
+}
+```
+
+### options.engines
+
+Define custom engines for parsing and/or stringifying front-matter.
+
+**Type**: `Object` Object of engines
+
+**Default**: `JSON`, `YAML` and `JavaScript` are already handled by default.
+
+**Engine format**
+
+Engines may either be an object with `parse` and (optionally) `stringify` methods, or a function that will be used for parsing only.
+
+**Examples**
+
+```js
+var toml = require('toml');
+
+/**
+ * defined as a function
+ */
+
+var file = matter(str, {
+  engines: {
+    toml: toml.parse.bind(toml),
+  }
+});
+
+/**
+ * Or as an object
+ */
+
+var file = matter(str, {
+  engines: {
+    toml: {
+      parse: toml.parse.bind(toml),
+
+      // example of throwing an error to let users know stringifying is
+      // not supported (a TOML stringifier might exist, this is just an example)
+      stringify: function() {
+        throw new Error('cannot stringify to TOML');
+      }
+    }
+  }
+});
+
+console.log(file);
+```
+
+### options.language
+
+**Type**: `String`
+
+**Default**: `yaml`
+
+Define the engine to use for parsing front-matter.
+
+```js
+console.log(matter(string, {language: 'toml'}));
+```
+
+**Example**
+
+The following HTML string:
+
+```html
+---
+title = "TOML"
+description = "Front matter"
+categories = "front matter toml"
+---
+This is content
+```
+
+Results in:
+
+```js
+{ content: 'This is content',
+  excerpt: '',
+  data:
+   { title: 'TOML',
+     description: 'Front matter',
+     categories: 'front matter toml' } }
+```
+
+**Dynamic language detection**
+
+Instead of defining the language on the options, gray-matter will automatically detect the language defined after the first delimiter and select the correct engine to use for parsing.
+
+```html
+---toml
+title = "TOML"
+description = "Front matter"
+categories = "front matter toml"
+---
+This is content
+```
+
+### options.delimiters
+
+**Type**: `String`
+
+**Default**: `---`
+
+Open and close delimiters can be passed in as an array of strings.
+
+**Example:**
+
+```js
+// format delims as a string
+matter.read('file.md', {delims: '~~~'});
+// or an array (open/close)
+matter.read('file.md', {delims: ['~~~', '~~~']});
+```
+
+would parse:
+
+```html
+~~~
+title: Home
+~~~
+This is the {{title}} page.
+```
+

+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save group-array
+```
+
+## Usage
+
+```js
+var groupArray = require('group-array');
+```
+
+## Examples
+
+```js
+var arr = [
+  {tag: 'one', content: 'A'},
+  {tag: 'one', content: 'B'},
+  {tag: 'two', content: 'C'},
+  {tag: 'two', content: 'D'},
+  {tag: 'three', content: 'E'},
+  {tag: 'three', content: 'F'}
+];
+
+// group by the `tag` property
+groupArray(arr, 'tag');
+```
+
+**results in:**
+
+```js
+{
+  one: [
+    {tag: 'one', content: 'A'},
+    {tag: 'one', content: 'B'}
+  ],
+  two: [
+    {tag: 'two', content: 'C'},
+    {tag: 'two', content: 'D'}
+  ],
+  three: [
+    {tag: 'three', content: 'E'},
+    {tag: 'three', content: 'F'}
+  ]
+}
+```
+
+**Group by multiple, deeply nested properties**
+
+```js
+// given an array of object, like blog posts...
+var arr = [
+  { data: { year: '2016', tag: 'one', month: 'jan', day: '01'}, content: '...'},
+  { data: { year: '2016', tag: 'one', month: 'jan', day: '01'}, content: '...'},

+  { data: { year: '2016', tag: 'two', month: 'feb', day: '18'}, content: '...'},
+  { data: { year: '2017', tag: 'two', month: 'feb', day: '18'}, content: '...'},
+  { data: { year: '2017', tag: 'two', month: 'feb', day: '10'}, content: '...'},
+  { data: { year: '2017', tag: 'two', month: 'feb', day: '10'}, content: '...'},
+  { data: { year: '2017', tag: 'three', month: 'jan', day: '01'}, content: '...'},
+  { data: { year: '2017', tag: 'three', month: 'jan', day: '01'}, content: '...'},

+  { data: { year: '2017', tag: 'three', month: 'feb', day: '02'}, content: '...'}
+]
+```
+
+Pass a list or array of properties:
+
+```js
+groupArray(arr, 'data.year', 'data.tag', 'data.month', 'data.day');
+```
+
+**Results in something like this: (abbreviated)**

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Split a string on a character except when the character is escaped.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save split-string
+```
+
+## Usage
+
+```js
+var split = require('split-string');
+
+split('a.b.c');
+//=> ['a', 'b', 'c']
+
+// respects escaped characters
+split('a.b.c\\.d');
+//=> ['a', 'b', 'c.d']
+
+// respects double-quoted strings
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+```
+
+## Options
+
+### options.sep
+
+**Type**: `String`
+
+**Default**: `.`
+
+The separator/character to split on.
+
+**Example**
+
+```js
+split('a.b,c', {sep: ','});
+//=> ['a.b', 'c']
+
+// you can also pass the separator as string as the last argument
+split('a.b,c', ',');
+//=> ['a.b', 'c']
+```
+
+### options.keepEscaping
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+Keep backslashes in the result.
+
+**Example**
+
+```js
+split('a.b\\.c');
+//=> ['a', 'b.c']
+
+split('a.b.\\c', {keepEscaping: true});
+//=> ['a', 'b\.c']
+```
+
+### options.keepDoubleQuotes
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+Keep double-quotes in the result.
+
+**Example**
+
+```js
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a."b.c.d".e', {keepDoubleQuotes: true});
+//=> ['a', 'b.c.d', 'e']
+```
+
+### options.keepSingleQuotes
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+Keep single-quotes in the result.
+
+**Example**
+
+```js
+split('a.\'b.c.d\'.e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a.\'b.c.d\'.e', {keepSingleQuotes: true});
+//=> ['a', 'b.c.d', 'e']
+```
+
+### options.strict
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+When `true` or `undefined`, throws an error on unclosed double and single quotes.
+Set to `false` to ignore errors and continue parsing.
+
+**Example**
+
+```js
+split('a.\'b.c', {strict: false});
+//=> ['a', 'b', 'c']
+```

+# gulp-choose-files [![NPM version](https://img.shields.io/npm/v/gulp-choose-files.svg?style=flat)](https://www.npmjs.com/package/gulp-choose-files) [![NPM downloads](https://img.shields.io/npm/dm/gulp-choose-files.svg?style=flat)](https://npmjs.org/package/gulp-choose-files)
+
+Gulp plugin that prompts you to choose the files to pass through the stream.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save gulp-choose-files
+```
+
+![gulp choose files example](example.gif)
+
+## Usage
+
+```js
+var gulp = require('gulp');
+var choose = require('gulp-choose-files');
+
+gulp.task('default', function() {
+  return gulp.src('fixtures/*.*')
+    .pipe(choose())
+    .pipe(gulp.dest('actual'));
+});
+```
+
+## options.choices
+
+If you need to be able to automatically skip the prompt, you can pass a string or array with your "choices" to `options.choices`.
+
+The following will only write `a.txt`:
+
+```js
+gulp.task('default', function() {
+  return gulp.src('fixtures/*.txt')
+    .pipe(choose({choices: ['a.txt']}))
+    .pipe(gulp.dest('actual'));
+});
+```

+## gulp-sourcemaps  [![NPM version][npm-image]][npm-url] [![build status][travis-image]][travis-url] [![Test coverage][coveralls-image]][coveralls-url]
+
+### Usage
+
+#### Write inline source maps
+Inline source maps are embedded in the source file.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write())
+    .pipe(gulp.dest('dist'));
+});
+```
+
+All plugins between `sourcemaps.init()` and `sourcemaps.write()` need to have support for `gulp-sourcemaps`. You can find a list of such plugins in the [wiki](https://github.com/floridoo/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support).
+
+
+#### Write external source map files
+
+To write external source map files, pass a path relative to the destination to `sourcemaps.write()`.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write('../maps'))
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Load existing source maps
+
+To load existing source maps, pass the option `loadMaps: true` to `sourcemaps.init()`.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init({loadMaps: true}))
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write())
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Handle source files from different directories
+
+Use the `base` option on `gulp.src` to make sure all files are relative to a common base directory.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+gulp.src(['src/test.js', 'src/testdir/test2.js'], { base: 'src' })
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write('../maps'))
+    .pipe(gulp.dest('dist'));
+});
+```
+
+
+
+### Init Options
+
+- `loadMaps`
+  Set to true to load existing maps for source files. Supports the following:
+    - inline source maps
+    - source map files referenced by a `sourceMappingURL=` comment
+    - source map files with the same name (plus .map) in the same directory
+
+- `debug`
+  Set this to `true` to output debug messages (e.g. about missing source content).
+
+### Write Options
+
+- `addComment`
+
+  By default a comment containing / referencing the source map is added. Set this to `false` to disable the comment (e.g. if you want to load the source maps by header).
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {addComment: false}))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+- `includeContent`
+
+  By default the source maps include the source code. Pass `false` to use the original files.
+
+  Including the content is the recommended way, because it "just works". When setting this to `false` you have to host the source files and set the correct `sourceRoot`.
+
+- `sourceRoot`
+
+  Set the path where the source files are hosted (use this when `includeContent` is set to `false`). This is an URL (or subpath) relative to the source map, not a local file system path. If you have sources in different subpaths, an absolute path (from the domain root) pointing to the source file root is recommended, or define it with a function.
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write({includeContent: false, sourceRoot: '/src'}))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+  Example (using a function):
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write({
+        includeContent: false,
+        sourceRoot: function(file) {
+          return '/src';
+        }
+       }))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+- `sourceMappingURLPrefix`
+
+  Specify a prefix to be prepended onto the source map URL when writing external source maps. Relative paths will have their leading dots stripped.
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {
+        sourceMappingURLPrefix: 'https://asset-host.example.com/assets'
+      }))
+      .pipe(gulp.dest('public/scripts'));
+  });
+  ```
+
+  This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/assets/maps/helloworld.js.map`.
+
+- `sourceMappingURL`
+
+  If you need full control over the source map URL you can pass a function to this option. The output of the function must be the full URL to the source map (in function of the output file).
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {
+        sourceMappingURL: function(file) {
+          return 'https://asset-host.example.com/' + file.relative + '.map';
+        }
+      }))
+      .pipe(gulp.dest('public/scripts'));
+  });
+  ```
+
+  This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/helloworld.js.map`.
+
+- `debug`
+
+  Set this to `true` to output debug messages (e.g. about missing source content).
+
+### Plugin developers only: How to add source map support to plugins
+
+- Generate a source map for the transformation the plugin is applying
+- **Important**: Make sure the paths in the generated source map (`file` and `sources`) are relative to `file.base` (e.g. use `file.relative`).
+- Apply this source map to the vinyl `file`. E.g. by using [vinyl-sourcemaps-apply](https://github.com/floridoo/vinyl-sourcemaps-apply).
+  This combines the source map of this plugin with the source maps coming from plugins further up the chain.
+- Add your plugin to the [wiki page](https://github.com/floridoo/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support)
+
+#### Example:
+
+```javascript
+var through = require('through2');
+var applySourceMap = require('vinyl-sourcemaps-apply');
+var myTransform = require('myTransform');
+
+module.exports = function(options) {
+
+  function transform(file, encoding, callback) {
+    // generate source maps if plugin source-map present
+    if (file.sourceMap) {
+      options.makeSourceMaps = true;
+    }
+
+    // do normal plugin logic
+    var result = myTransform(file.contents, options);
+    file.contents = new Buffer(result.code);
+
+    // apply source map to the chain
+    if (file.sourceMap) {
+      applySourceMap(file, result.map);
+    }
+
+    this.push(file);
+    callback();
+  }
+
+  return through.obj(transform);
+};
+```

+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i has-glob --save
+```
+
+## Usage
+
+```js
+var hasGlob = require('has-glob');
+
+hasGlob(['foo', 'bar', '*.js']);
+//=> true
+
+hasGlob(['foo', 'bar', 'baz']);
+//=> false
+```
+
+**True**
+
+The following all return `true`:
+
+```js
+hasGlob(['foo', 'bar', '*.js'])
+hasGlob(['foo', 'bar', '!*.js'])
+hasGlob(['foo', 'bar', '!foo'])
+hasGlob(['foo', 'bar', '!foo.js'])
+hasGlob(['foo', 'bar', '**/abc.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/{a,b}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z..2}.js'])
+hasGlob(['foo', 'bar', 'abc/@(a).js'])
+hasGlob(['foo', 'bar', 'abc/!(a).js'])
+hasGlob(['foo', 'bar', 'abc/+(a).js'])
+hasGlob(['foo', 'bar', 'abc/*(a).js'])
+hasGlob(['foo', 'bar', 'abc/?(a).js'])
+hasGlob(['foo', 'bar', 'abc/@.js'])
+hasGlob(['foo', 'bar', 'abc/!.js'])
+hasGlob(['foo', 'bar', 'abc/+.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', 'abc/(aaa|bbb).js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', '?.js'])
+hasGlob(['foo', 'bar', '[abc].js'])
+hasGlob(['foo', 'bar', '[^abc].js'])
+hasGlob(['foo', 'bar', 'a/b/c/[a-z].js'])
+hasGlob(['foo', 'bar', '[a-j]*[^c]b/c'])
+//=> true
+```
+
+Also works with strings:
+
+```js
+hasGlob('*.js')
+hasGlob('!*.js')
+hasGlob('!foo')
+hasGlob('!foo.js')
+hasGlob('**/abc.js')
+hasGlob('abc/*.js')
+//=> true
+```
+
+**False**
+
+The following all return `false`:
+
+```js
+hasGlob([])
+hasGlob([null])
+hasGlob([undefined])
+hasGlob([{}])
+hasGlob(['.'])
+hasGlob(['foo', 'bar', 'aa'])
+hasGlob(['foo', 'bar', 'abc.js'])
+hasGlob(['foo', 'bar', 'abc/def/ghi.js'])
+//=> false
+```

+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+> Returns true if a value exists, false if empty. Works with deeply nested values using object paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install has-value --save
+```
+
+**Works for:**
+
+* booleans
+* functions
+* numbers (pass `true` as the last arg to treat zero as a value instead of falsey)
+* strings
+* nulls
+* object
+* arrays
+
+## Usage
+
+Works with nested object paths or a single value:
+
+```js
+var hasValue = require('has-value');
+
+hasValue({a: {b: {c: 'foo'}}} 'a.b.c');
+//=> true
+
+hasValue('a');
+//=> true
+
+hasValue('');
+//=> false
+
+hasValue(1);
+//=> true
+
+hasValue(0);
+//=> false
+
+hasValue(0, true); // pass `true` as the last arg to treat zero as a value
+//=> true
+
+hasValue({a: 'a'}});
+//=> true
+
+hasValue({}});
+//=> false
+
+hasValue(['a']);
+//=> true
+
+hasValue([]);
+//=> false
+
+hasValue(function(foo) {}); // function length/arity
+//=> true
+
+hasValue(function() {});
+//=> false
+
+hasValue(true);
+hasValue(false);
+//=> true
+```
+
+## isEmpty
+
+To do the opposite and test for empty values, do:
+
+```js
+function isEmpty(o, isZero) {
+  return !hasValue.apply(hasValue, arguments);
+}
+```

+> Returns true if any values exist, false if empty. Works for booleans, functions, numbers, strings, nulls, objects and arrays.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-values
+```
+
+## Usage
+
+```js
+var hasValue = require('has-values');
+
+hasValue('a');
+//=> true
+
+hasValue('');
+//=> false
+
+hasValue(1);
+//=> true
+
+hasValue(0);
+//=> false
+
+hasValue({a: 'a'}});
+//=> true
+
+hasValue({});
+hasValue({foo: undefined});
+//=> false
+
+hasValue({foo: null});
+//=> true
+
+hasValue(['a']);
+//=> true
+
+hasValue([]);
+hasValue([[], []]);
+hasValue([[[]]]);
+//=> false
+
+hasValue(['foo']);
+hasValue([0]);
+//=> true
+
+hasValue(function(foo) {}); 
+//=> true
+
+hasValue(function() {});
+//=> true
+
+hasValue(true);
+//=> true
+
+hasValue(false);
+//=> true
+```
+
+## isEmpty
+
+To test for empty values, do:
+
+```js
+function isEmpty(o, isZero) {
+  return !hasValue(o, isZero);
+}
+```
+
+## Release history
+
+### v1.0.0
+
+* `zero` always returns true
+* `array` now recurses, so that an array of empty arrays will return `false`
+* `null` now returns true

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Release history
+
+### v4.0.0
+
+**Added**
+
+* `promise` support
+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# helper-cache [![NPM version](https://badge.fury.io/js/helper-cache.svg)](http://badge.fury.io/js/helper-cache)  [![Build Status](https://travis-ci.org/jonschlinkert/helper-cache.svg)](https://travis-ci.org/jonschlinkert/helper-cache)
+
+> Easily register and get helper functions to be passed to any template engine or node.js application. Methods for both sync and async helpers.
+
+## Install with [npm](npmjs.org)
+
+```bash
+npm i helper-cache --save
+```
+
+## Usage
+
+### [HelperCache](index.js#L27)
+
+Create an instance of `HelperCache`, optionally passing default `options`.
+
+* `options` **{Object}**: Default options to use.  
+    - `bind` **{Boolean}**: Bind functions to `this`. Defaults to `false`.
+    - `thisArg` **{Boolean}**: The context to use.
+      
+
+```js
+var HelperCache = require('helper-cache');
+var helpers = new HelperCache();
+```
+
+### [.addHelper](index.js#L53)
+
+Register a helper.
+
+* `name` **{String}**: The name of the helper.    
+* `fn` **{Function}**: Helper function.    
+* `returns` **{Object}**: Return `this` to enable chaining  
+
+```js
+helpers.addHelper('lower', function(str) {
+  return str.toLowerCase();
+});
+```
+
+### [.addAsyncHelper](index.js#L106)
+
+Register an async helper.
+
+* `key` **{String}**: The name of the helper.    
+* `fn` **{Function}**: Helper function.    
+* `returns` **{Object}**: Return `this` to enable chaining  
+
+```js
+helpers.addAsyncHelper('foo', function (str, callback) {
+  callback(null, str + ' foo');
+});
+```
+
+### [.addHelpers](index.js#L165)
+
+Load an object of helpers.
+
+* `key` **{String}**: The name of the helper.    
+* `fn` **{Function}**: Helper function.    
+* `returns` **{Object}**: Return `this` to enable chaining.  
+
+```js
+helpers.addHelpers({
+  a: function() {},
+  b: function() {},
+  c: function() {},
+});
+```
+
+### [.addAsyncHelpers](index.js#L202)
+
+Load an object of async helpers.
+
+* `key` **{String}**: The name of the helper.    
+* `fn` **{Function}**: Helper function.    
+* `returns` **{Object}**: Return `this` to enable chaining  
+
+```js
+helpers.addAsyncHelpers({
+  a: function() {},
+  b: function() {},
+  c: function() {},
+});
+```
+
+### [.getHelper](index.js#L234)
+
+Get a registered helper.
+
+* `key` **{String}**: The helper to get.    
+* `returns` **{Object}**: The specified helper. If no `key` is passed, the entire cache is returned.  
+
+```js
+helpers.getHelper('foo');
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+> Node.js os.homedir polyfill for older versions of node.js.
+
+Please consider following this project's author, [Brian Woodward](https://github.com/doowb), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save homedir-polyfill
+```
+
+## Usage
+
+```js
+var homedir = require('homedir-polyfill');
+console.log(homedir());
+//=> /Users/doowb
+```
+
+## Reasoning
+
+This library is a polyfill for the [node.js os.homedir](https://nodejs.org/api/os.html#os_os_homedir) method found in modern versions of node.js.
+
+This implementation tries to follow the implementation found in `libuv` by finding the current user using the `process.geteuid()` method and the `/etc/passwd` file. This should usually work in a linux environment, but will also fallback to looking at user specific environment variables to build the user's home directory if neccessary.
+
+Since `/etc/passwd` is not available on windows platforms, this implementation will use environment variables to find the home directory.
+
+In modern versions of node.js, [os.homedir](https://nodejs.org/api/os.html#os_os_homedir) is used.

+# inflection
+
+A port of inflection-js to node.js module
+
+
+
+## Description
+[inflection-js](http://code.google.com/p/inflection-js/) is a port of the functionality from Ruby on Rails' Active Support Inflection classes into Javascript. `inflection` is a port of `inflection-js` to node.js npm package. Instead of [extending JavaScript native](http://wonko.com/post/extending-javascript-natives) String object like `inflection-js` does, `inflection` separate the methods to a independent package to avoid unexpected behaviors.
+
+Note: This library uses [Wiktionary](http://en.wiktionary.org) as its reference.
+
+
+
+## Requires
+
+Checkout `package.json` for dependencies.
+
+
+
+## Angular Support
+
+Checkout [ngInflection](https://github.com/konsumer/ngInflection) from [konsumer](https://github.com/konsumer)

+Add callbacks to requests in flight to avoid async duplication

+## USAGE
+
+```javascript
+var inflight = require('inflight')
+
+// some request that does some stuff
+function req(key, callback) {
+  // key is any random string.  like a url or filename or whatever.
+  //
+  // will return either a falsey value, indicating that the
+  // request for this key is already in flight, or a new callback
+  // which when called will call all callbacks passed to inflightk
+  // with the same key
+  callback = inflight(key, callback)
+
+  // If we got a falsey value back, then there's already a req going
+  if (!callback) return
+
+  // this is where you'd fetch the url or whatever
+  // callback is also once()-ified, so it can safely be assigned
+  // to multiple events etc.  First call wins.
+  setTimeout(function() {
+    callback(null, key)
+  }, 100)
+}
+
+// only assigns a single setTimeout
+// when it dings, all cbs get called
+req('foo', cb1)
+req('foo', cb2)
+req('foo', cb3)

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+An ini format parser and serializer for node.
+
+Sections are treated as nested objects.  Items before the first
+heading are saved on the object directly.
+
+## Usage
+
+Consider an ini-file `config.ini` that looks like this:
+
+    ; this comment is being ignored
+    scope = global
+
+    [database]
+    user = dbuser
+    password = dbpassword
+    database = use_this_database
+
+    [paths.default]
+    datadir = /var/lib/data
+    array[] = first value
+    array[] = second value
+    array[] = third value
+
+You can read, manipulate and write the ini-file like so:
+
+    var fs = require('fs')
+      , ini = require('ini')
+
+    var config = ini.parse(fs.readFileSync('./config.ini', 'utf-8'))
+
+    config.scope = 'local'
+    config.database.database = 'use_another_database'
+    config.paths.default.tmpdir = '/tmp'
+    delete config.paths.default.datadir
+    config.paths.default.array.push('fourth value')
+
+    fs.writeFileSync('./config_modified.ini', ini.stringify(config, { section: 'section' }))
+
+This will result in a file called `config_modified.ini` being written
+to the filesystem with the following content:
+
+    [section]
+    scope=local
+    [section.database]
+    user=dbuser
+    password=dbpassword
+    database=use_another_database
+    [section.paths.default]
+    tmpdir=/tmp
+    array[]=first value
+    array[]=second value
+    array[]=third value
+    array[]=fourth value
+
+
+## API
+
+### decode(inistring)
+
+Decode the ini-style formatted `inistring` into a nested object.
+
+### parse(inistring)
+
+Alias for `decode(inistring)`
+
+### encode(object, [options])
+
+Encode the object `object` into an ini-style formatted string. If the
+optional parameter `section` is given, then all top-level properties
+of the object are put into this section and the `section`-string is
+prepended to all sub-sections, see the usage example above.
+
+The `options` object may contain the following:
+
+* `section` A string which will be the first `section` in the encoded
+  ini data.  Defaults to none.
+* `whitespace` Boolean to specify whether to put whitespace around the
+  `=` character.  By default, whitespace is omitted, to be friendly to
+  some persnickety old parsers that don't tolerate it well.  But some
+  find that it's more human-readable and pretty with the whitespace.
+
+For backwards compatibility reasons, if a `string` options is passed
+in, then it is assumed to be the `section` value.
+
+### stringify(object, [options])
+
+Alias for `encode(object, [options])`
+
+### safe(val)
+
+Escapes the string `val` such that it is safe to be used as a key or
+value in an ini-file. Basically escapes quotes. For example
+
+    ini.safe('"unsafe string"')
+
+would result in
+
+    "\"unsafe string\""
+
+### unsafe(val)
+
+Unescapes the string `val`

+
+> A collection of common interactive command line user interfaces.
+
+## Goal and Philosophy
+
+<img align="right" alt="Inquirer Logo" src="/assets/inquirer_readme.png" title="Inquirer.js"/>
+
+**`Inquirer.js`** strives to be an easily embeddable and beautiful command line interface for [Node.js](https://nodejs.org/) (and perhaps the "CLI [Xanadu](https://en.wikipedia.org/wiki/Xanadu_(Citizen_Kane))").
+
+**`Inquirer.js`** should ease the process of
+- providing *error feedback*
+- *asking questions*
+- *parsing* input
+- *validating* answers
+- managing *hierarchical prompts*
+
+> **Note:** **`Inquirer.js`** provides the user interface, and the inquiry session flow. If you're searching for a full blown command line program utility, then check out [Commander.js](https://github.com/visionmedia/commander.js).
+
+
+## Documentation
+
+### Installation
+
+```sh
+npm install inquirer
+```
+
+```js
+var inquirer = require("inquirer");
+inquirer.prompt([/* Pass your questions in here */], function( answers ) {
+	// Use user feedback for... whatever!!
+});
+```
+
+
+### Examples (Run it and see it)
+Checkout the `examples/` folder for code and interface examples.
+
+```sh
+node examples/pizza.js
+node examples/checkbox.js
+# etc...
+```
+
+
+### Methods
+
+`inquirer.prompt( questions, callback )`
+
+Launch the prompt interface (inquiry session)
+
+- **questions** (Array) containing [Question Object](#question) (using the [reactive interface](#reactive-interface), you can also pass a `Rx.Observable` instance)
+- **callback** (Function) first parameter is the [Answers Object](#answers)
+
+
+### Objects
+
+#### Question
+A question object is a `hash` containing question related values:
+
+- **type**: (String) Type of the prompt. Defaults: `input` - Possible values: `input`, `confirm`,
+`list`, `rawlist`, `password`
+- **name**: (String) The name to use when storing the answer in the answers hash.
+- **message**: (String|Function) The question to print. If defined as a function, the first parameter will be the current inquirer session answers.
+- **default**: (String|Number|Array|Function) Default value(s) to use if nothing is entered, or a function that returns the default value(s). If defined as a function, the first parameter will be the current inquirer session answers.
+- **choices**: (Array|Function) Choices array or a function returning a choices array. If defined as a function, the first parameter will be the current inquirer session answers.
+Array values can be simple `strings`, or `objects` containing a `name` (to display in list), a `value` (to save in the answers hash) and a `short` (to display after selection) properties. The choices array can also contain [a `Separator`](#separator).
+- **validate**: (Function) Receive the user input and should return `true` if the value is valid, and an error message (`String`) otherwise. If `false` is returned, a default error message is provided.
+- **filter**: (Function) Receive the user input and return the filtered value to be used inside the program. The value returned will be added to the _Answers_ hash.
+- **when**: (Function, Boolean) Receive the current user answers hash and should return `true` or `false` depending on whether or not this question should be asked. The value can also be a simple boolean.
+
+`default`, `choices`(if defined as functions), `validate`, `filter` and `when` functions can be called asynchronously using `this.async()`. You just have to pass the value you'd normally return to the callback option.
+
+``` javascript
+{
+  validate: function(input) {
+
+    // Declare function as asynchronous, and save the done callback
+    var done = this.async();
+
+    // Do async stuff
+    setTimeout(function() {
+      if (typeof input !== "number") {
+        // Pass the return value in the done callback
+        done("You need to provide a number");
+        return;
+      }
+      // Pass the return value in the done callback
+      done(true);
+    }, 3000);
+  }
+}
+```
+
+### Answers
+A key/value hash containing the client answers in each prompt.
+
+- **Key** The `name` property of the _question_ object
+- **Value** (Depends on the prompt)
+  - `confirm`: (Boolean)
+  - `input` : User input (filtered if `filter` is defined) (String)
+  - `rawlist`, `list` : Selected choice value (or name if no value specified) (String)
+
+### Separator
+
+A separator can be added to any `choices` array:
+
+```
+// In the question object
+choices: [ "Choice A", new inquirer.Separator(), "choice B" ]
+
+// Which'll be displayed this way
+[?] What do you want to do?
+ > Order a pizza
+   Make a reservation
+   -------
+   Ask opening hours
+   Talk to the receptionist
+```
+
+The constructor takes a facultative `String` value that'll be use as the separator. If omitted, the separator will be `--------`.
+
+Separator instances have a property `type` equal to `separator`. This should allow tools façading Inquirer interface from detecting separator types in lists.
+
+### Prompts type
+
+> **Note:**: _allowed options written inside square brackets (`[]`) are optional. Others are required._
+
+#### List - `{ type: "list" }`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must be the choice `index` in the array or a choice `value`)
+
+![List prompt](https://dl.dropboxusercontent.com/u/59696254/inquirer/list-prompt.png)
+
+***
+
+#### Raw List - `{ type: "rawlist" }`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must the choice `index` in the array)
+
+![Raw list prompt](https://i.cloudup.com/LcRGpXI0CX-3000x3000.png)
+
+***
+
+#### Expand - `{ type: "expand" }`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must be the choice `index` in the array)
+
+Note that the `choices` object will take an extra parameter called `key` for the `expand` prompt. This parameter must be a single (lowercased) character. The `h` option is added by the prompt and shouldn't be defined by the user.
+
+See `examples/expand.js` for a running example.
+
+![Expand prompt closed](https://dl.dropboxusercontent.com/u/59696254/inquirer/expand-prompt-1.png)
+![Expand prompt expanded](https://dl.dropboxusercontent.com/u/59696254/inquirer/expand-prompt-2.png)
+
+***
+
+#### Checkbox - `{ type: "checkbox" }`
+
+Take `type`, `name`, `message`, `choices`[, `filter`, `validate`, `default`] properties. `default` is expected to be an Array of the checked choices value.
+
+Choices marked as `{ checked: true }` will be checked by default.
+
+Choices whose property `disabled` is truthy will be unselectable. If `disabled` is a string, then the string will be outputted next to the disabled choice, otherwise it'll default to `"Disabled"`. The `disabled` property can also be a synchronous function receiving the current answers as argument and returning a boolean or a string.
+
+![Checkbox prompt](https://dl.dropboxusercontent.com/u/59696254/inquirer/checkbox-prompt.png)
+
+***
+
+#### Confirm - `{ type: "confirm" }`
+
+Take `type`, `name`, `message`[, `default`] properties. `default` is expected to be a boolean if used.
+
+![Confirm prompt](https://dl.dropboxusercontent.com/u/59696254/inquirer/confirm-prompt.png)
+
+***
+
+#### Input - `{ type: "input" }`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties.
+
+![Input prompt](https://dl.dropboxusercontent.com/u/59696254/inquirer/input-prompt.png)
+
+***
+
+#### Password - `{ type: "password" }`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties.
+
+![Password prompt](https://dl.dropboxusercontent.com/u/59696254/inquirer/password-prompt.png)
+
+## User Interfaces and layouts
+
+Along with the prompts, Inquirer offers some basic text UI.
+
+#### Bottom Bar - `inquirer.ui.BottomBar`
+
+This UI present a fixed text at the bottom of a free text zone. This is useful to keep a message to the bottom of the screen while outputting command outputs on the higher section.
+
+```js
+var ui = new inquirer.ui.BottomBar();
+
+// pipe a Stream to the log zone
+outputStream.pipe( ui.log );
+
+// Or simply write output
+ui.log.write("something just happened.");
+ui.log.write("Almost over, standby!");
+
+// During processing, update the bottom bar content to display a loader
+// or output a progress bar, etc
+ui.updateBottomBar("new bottom bar content");
+```
+
+#### Prompt - `inquirer.ui.Prompt`
+
+This is UI layout used to run prompt. This layout is returned by `inquirer.prompt` and you should probably always use `inquirer.prompt` to interface with this UI.
+
+
+## Reactive interface
+
+Internally, Inquirer uses the [JS reactive extension](https://github.com/Reactive-Extensions/RxJS) to handle events and async flows.
+
+This mean you can take advantage of this feature to provide more advanced flows. For example, you can dynamically add questions to be asked:
+
+```js
+var prompts = Rx.Observable.create(function( obs ) {
+  obs.onNext({ /* question... */ });
+  setTimeout(function () {
+    obs.onNext({ /* question... */ });
+    obs.onCompleted();
+  });
+});
+
+inquirer.prompt(prompts);
+```
+
+And using the `process` property, you have access to more fine grained callbacks:
+
+```js
+inquirer.prompt(prompts).process.subscribe(
+  onEachAnswer,
+  onError,
+  onComplete
+);
+```
+
+## Support (OS Terminals)
+
+You should expect mostly good support for the CLI below. This does not mean we won't
+look at issues found on other command line - feel free to report any!
+
+- **Mac OS**:
+  - Terminal.app
+  - iTerm
+- **Windows**:
+  - cmd.exe
+  - Powershell
+  - Cygwin
+- **Linux (Ubuntu, openSUSE, Arch Linux, etc)**:
+  - gnome-terminal (Terminal GNOME)
+  - konsole
+
+

+# lazy-cache [![NPM version](https://img.shields.io/npm/v/lazy-cache.svg?style=flat)](https://www.npmjs.com/package/lazy-cache) [![NPM downloads](https://img.shields.io/npm/dm/lazy-cache.svg?style=flat)](https://npmjs.org/package/lazy-cache) [![Build Status](https://img.shields.io/travis/jonschlinkert/lazy-cache.svg?style=flat)](https://travis-ci.org/jonschlinkert/lazy-cache)
+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+
+> Polyfill for node.js `path.isAbolute`. Returns true if a file path is absolute.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-absolute
+```
+
+Originally based on the `isAbsolute` utility method in [express](https://github.com/visionmedia/express).
+
+## Usage
+
+```js
+var isAbsolute = require('is-absolute');
+
+isAbsolute('a/b/c.js');
+//=> 'false'
+isAbsolute('/a/b/c.js');
+//=> 'true'
+```
+
+**Explicitly test windows paths**
+
+```js
+isAbsolute.posix('/foo/bar');
+isAbsolute.posix('/user/docs/Letter.txt');
+//=> true
+
+isAbsolute.posix('foo/bar');
+//=> false
+```
+
+**Explicitly test windows paths**
+
+```js
+var isAbsolute = require('is-absolute');
+
+isAbsolute.win32('c:\\');
+isAbsolute.win32('//C://user\\docs\\Letter.txt');
+isAbsolute.win32('\\\\unc\\share');
+isAbsolute.win32('\\\\unc\\share\\foo');
+isAbsolute.win32('\\\\unc\\share\\foo\\');
+isAbsolute.win32('\\\\unc\\share\\foo\\bar');
+isAbsolute.win32('\\\\unc\\share\\foo\\bar\\');
+isAbsolute.win32('\\\\unc\\share\\foo\\bar\\baz');
+//=> true
+
+isAbsolute.win32('a:foo/a/b/c/d');
+isAbsolute.win32(':\\');
+isAbsolute.win32('foo\\bar\\baz');
+isAbsolute.win32('foo\\bar\\baz\\');
+//=> false
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i is-accessor-descriptor --save
+```
+
+## Usage
+
+```js
+var isAccessor = require('is-accessor-descriptor');
+
+isAccessor({get: function() {}});
+//=> true
+```
+
+You may also pass an object and property name to check if the property is an accessor:
+
+```js
+isAccessor(foo, 'bar');
+```
+
+## Examples
+
+`false` when not an object
+
+```js
+isAccessor('a')
+isAccessor(null)
+isAccessor([])
+//=> false
+```
+
+`true` when the object has valid properties
+
+and the properties all have the correct JavaScript types:
+
+```js
+isAccessor({get: noop, set: noop})
+isAccessor({get: noop})
+isAccessor({set: noop})
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isAccessor({get: noop, set: noop, bar: 'baz'})
+isAccessor({get: noop, writable: true})
+isAccessor({get: noop, value: true})
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isAccessor({get: noop, set: 'baz'})
+isAccessor({get: 'foo', set: noop})
+isAccessor({get: 'foo', bar: 'baz'})
+isAccessor({get: 'foo', set: 'baz'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isAccessor({get: noop, set: noop, enumerable: 'foo'})
+isAccessor({set: noop, configurable: 'foo'})
+isAccessor({get: noop, configurable: 'foo'})
+//=> false
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+Is this an arguments object? It's a harder question than you think.
+
+## Example
+
+```js
+var isArguments = require('is-arguments');
+var assert = require('assert');
+
+assert.equal(isArguments({}), false);
+assert.equal(isArguments([]), false);
+(function () {
+	assert.equal(isArguments(arguments), true);
+}())
+```
+
+## Caveats
+If you have modified an actual `arguments` object by giving it a `Symbol.toStringTag` property, then this package will return `false`.
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+> Returns true if a buffer is binary. Takes a buffer and does not read from the file system.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-binary-buffer
+```
+
+## What is this?
+
+This a node.js library written in pure javascript that can be used to check if the given value is a "binary buffer".
+
+## Usage
+
+You can add this library to your node.js application using node's `require()` system with the following line of code:
+
+```js
+var fs = require('fs');
+var isBinary = require('is-binary-buffer');
+
+console.log(isBinary('foo'));             
+console.log(isBinary(new Buffer('foo'))); 
+//=> false
+
+console.log(isBinary(fs.readFileSync('some-image.jpg'))); 
+console.log(isBinary(fs.readFileSync('some-image.gif'))); 
+//=> true
+```
+
+## Attribution
+
+Based on the code from [isbinaryfile](https://github.com/gjtorikian/isBinaryFile), which only reads from the file system. If the file doesn't exist, is a directory, or is empty, the function returns false.
+

+
+## Why not use `Buffer.isBuffer`?
+
+This module lets you check if an object is a `Buffer` without using `Buffer.isBuffer` (which includes the whole [buffer](https://github.com/feross/buffer) module in [browserify](http://browserify.org/)).
+
+It's future-proof and works in node too!
+
+## install
+
+```bash
+npm install is-buffer
+```
+
+## usage
+
+```js
+var isBuffer = require('is-buffer')
+
+isBuffer(new Buffer(4)) // true
+
+isBuffer(undefined) // false
+isBuffer(null) // false
+isBuffer('') // false
+isBuffer(true) // false
+isBuffer(false) // false
+isBuffer(0) // false
+isBuffer(1) // false
+isBuffer(1.0) // false
+isBuffer('string') // false
+isBuffer({}) // false
+isBuffer(function foo () {}) // false
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript data descriptor.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i is-data-descriptor --save
+```
+
+## Usage
+
+```js
+var isDataDesc = require('is-data-descriptor');
+```
+
+## Examples
+
+`true` when the descriptor has valid properties with valid values.
+
+```js
+// `value` can be anything
+isDataDesc({value: 'foo'})
+isDataDesc({value: function() {}})
+isDataDesc({value: true})
+//=> true
+```
+
+`false` when not an object
+
+```js
+isDataDesc('a')
+//=> false
+isDataDesc(null)
+//=> false
+isDataDesc([])
+//=> false
+```
+
+`false` when the object has invalid properties
+
+```js
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', bar: 'baz'})
+//=> false
+isDataDesc({value: 'foo', get: function(){}})
+//=> false
+isDataDesc({get: function(){}, value: 'foo'})
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDataDesc({value: 'foo', enumerable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', configurable: 'foo'})
+//=> false
+isDataDesc({value: 'foo', writable: 'foo'})
+//=> false
+```
+
+## Valid properties
+
+The only valid data descriptor properties are the following:
+
+* `configurable` (required)
+* `enumerable` (required)
+* `value` (optional)
+* `writable` (optional)
+
+To be a valid data descriptor, either `value` or `writable` must be defined.
+
+**Invalid properties**
+
+A descriptor may have additional _invalid_ properties (an error will **not** be thrown).
+
+```js
+var foo = {};
+
+Object.defineProperty(foo, 'bar', {
+  enumerable: true,
+  whatever: 'blah', // invalid, but doesn't cause an error
+  get: function() {
+    return 'baz';
+  }
+});
+
+console.log(foo.bar);
+//=> 'baz'
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+Is this value a JS Date object? This module works cross-realm/iframe, and despite ES6 @@toStringTag.
+
+## Example
+
+```js
+var isDate = require('is-date-object');
+var assert = require('assert');
+
+assert.notOk(isDate(undefined));
+assert.notOk(isDate(null));
+assert.notOk(isDate(false));
+assert.notOk(isDate(true));
+assert.notOk(isDate(42));
+assert.notOk(isDate('foo'));
+assert.notOk(isDate(function () {}));
+assert.notOk(isDate([]));
+assert.notOk(isDate({}));
+assert.notOk(isDate(/a/g));
+assert.notOk(isDate(new RegExp('a', 'g')));
+
+assert.ok(isDate(new Date()));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false
+isDescriptor({get: noop, configurable: 'foo'});
+//=> false
+```

+
+Install with [npm](https://www.npmjs.com/):
+
+```sh

+```
+
+## Usage
+
+To be considered a dotfile, it must be the last filename in the path, like `.gitignore`. Otherwise it's a [dot directory](https://github.com/jonschlinkert/is-dotdir), like `.git/` and `.github/`.
+
+```js
+var isDotfile = require('is-dotfile');
+```
+
+**false**
+
+All of the following return `false`:
+
+```js
+isDotfile('a/b/c.js');
+isDotfile('/.git/foo');
+isDotfile('a/b/c/.git/foo');
+//=> false
+```
+
+**true**
+
+All of the following return `true`:
+
+```js
+isDotfile('a/b/.gitignore');
+isDotfile('.gitignore');
+isDotfile('/.gitignore');

+# is-equal-shallow [![NPM version](https://badge.fury.io/js/is-equal-shallow.svg)](http://badge.fury.io/js/is-equal-shallow)  [![Build Status](https://travis-ci.org/jonschlinkert/is-equal-shallow.svg)](https://travis-ci.org/jonschlinkert/is-equal-shallow)
+
+> Does a shallow comparison of two objects, returning false if the keys or values differ.
+
+The purpose of this lib is to do the fastest comparison possible of two objects when the values will predictably be primitives.
+
+* only compares objects.
+* only compares the first level of each object
+* values must be primitives. If a value is not a primitive, even if the values are the same, `false` is returned.
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-equal-shallow --save
+```
+
+## Usage
+
+```js
+var equals = require('is-equal-shallow');
+equals(object_a, object_b);
+```
+
+**Examples**
+
+```js
+equals({a: true, b: true}, {a: true, b: true});
+//=> 'true'
+
+equals({a: true, b: false}, {c: false, b: false});
+//=> 'false'
+
+equals({a: true, b: false}, {a: false, b: false});
+//=> 'false'
+```
+
+Strict comparison for equality:
+
+```js
+equals({a: true, b: true}, {a: true, b: 'true'});
+//=> 'false'
+```
+
+When values are not primitives, `false` is always returned:
+
+```js
+equals({ b: {}}, { b: {}});
+//=> 'false'
+
+equals({ b: []}, { b: []});
+//=> 'false'
+```

+# is-extendable [![NPM version](https://badge.fury.io/js/is-extendable.svg)](http://badge.fury.io/js/is-extendable)
+
+> Returns true if a value is any of the object types: array, regexp, plain object, function or date. This is useful for determining if a value can be extended, e.g. "can the value have keys?"
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-extendable --save
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* `array`
+* `regexp`
+* `plain object`
+* `function`
+* `date`
+* `error`
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is an `object`, `function`
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+

+* [extend-shallow](https://github.com/jonschlinkert/extend-shallow): Extend an object with the properties of additional objects. node.js/javascript util.
+* [isobject](https://github.com/jonschlinkert/isobject): Returns true if the value is an object and not an array or null.

+
+> Returns true if a string has an extglob.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extglob
+```
+
+## Usage
+
+```js
+var isExtglob = require('is-extglob');
+```
+
+**True**
+
+```js
+isExtglob('?(abc)');
+isExtglob('@(abc)');
+isExtglob('!(abc)');
+isExtglob('*(abc)');
+isExtglob('+(abc)');
+```
+
+**False**
+
+Escaped extglobs:
+
+```js
+isExtglob('\\?(abc)');
+isExtglob('\\@(abc)');
+isExtglob('\\!(abc)');
+isExtglob('\\*(abc)');
+isExtglob('\\+(abc)');
+```
+
+Everything else...
+
+```js
+isExtglob('foo.js');
+isExtglob('!foo.js');
+isExtglob('*.js');
+isExtglob('**/abc.js');
+isExtglob('abc/*.js');
+isExtglob('abc/(aaa|bbb).js');
+isExtglob('abc/[a-z].js');
+isExtglob('abc/{a,b}.js');
+isExtglob('abc/?.js');
+isExtglob('abc.js');
+isExtglob('abc/def/ghi.js');
+```
+
+## History
+
+**v2.0**
+
+Adds support for escaping. Escaped exglobs no longer return true.

+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-glob
+```
+
+You might also be interested in [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Escaped globs or extglobs return `false`:
+
+```js
+isGlob('abc/\\@(a).js');
+isGlob('abc/\\!(a).js');
+isGlob('abc/\\+(a).js');
+isGlob('abc/\\*(a).js');
+isGlob('abc/\\?(a).js');
+isGlob('\\!foo.js');
+isGlob('\\*.js');
+isGlob('\\*\\*/abc.js');
+isGlob('abc/\\*.js');
+isGlob('abc/\\(aaa|bbb).js');
+isGlob('abc/\\[a-z].js');
+isGlob('abc/\\{a,b}.js');
+isGlob('abc/\\?.js');
+//=> false
+```
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+> Returns true if an object was created by the `Object` constructor.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-plain-object
+```
+
+Use [isobject](https://github.com/jonschlinkert/isobject) if you only want to check if the value is an object and not an array or null.
+
+## Usage
+
+```js
+var isPlainObject = require('is-plain-object');
+```
+
+**true** when created by the `Object` constructor.
+
+```js
+isPlainObject(Object.create({}));
+//=> true
+isPlainObject(Object.create(Object.prototype));
+//=> true
+isPlainObject({foo: 'bar'});
+//=> true
+isPlainObject({});
+//=> true
+```
+
+**false** when not created by the `Object` constructor.
+
+```js
+isPlainObject(1);
+//=> false
+isPlainObject(['foo', 'bar']);
+//=> false
+isPlainObject([]);
+//=> false
+isPlainObject(new Foo);
+//=> false
+isPlainObject(null);
+//=> false
+isPlainObject(Object.create(null));
+//=> false
+```

+```js
+var myRegex = new RegExp(isUncPath.source + 'foo');

+
+> Wrapper around is-valid-instance and is-registered for validating `base` plugins. Returns true if `app` is a valid instance of base and a plugin is not registered yet.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-app
+```
+
+## Usage
+
+```js
+var isValid = require('is-valid-app');
+
+// in your Base plugin
+function plugin(app) {
+  // plugin name is required as the second argument
+  if (!isValid(app, 'my-plugin')) return;
+  // do plugin stuff
+}
+```
+
+Optionally pass an array of instance types as the third argument:
+
+```js
+function plugin(app) {
+  if (!isValid(app, 'my-plugin', ['view', 'collection'])) return;
+  // do plugin stuff
+}
+```

+# is-valid-glob [![NPM version](https://badge.fury.io/js/is-valid-glob.svg)](http://badge.fury.io/js/is-valid-glob)
+
+> Return true if a value is a valid glob pattern or patterns.
+
+This really just checks to make sure that a pattern is either a string or array, and if it's an array it's either empty or consists of only strings.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-valid-glob --save
+```
+
+## Usage
+
+```js
+var isValidGlob = require('is-valid-glob');
+
+isValidGlob('foo/*.js');
+//=> true
+```
+
+**Valid patterns**
+
+```js
+isValidGlob('a');
+isValidGlob('a.js');
+isValidGlob('*.js');
+isValidGlob(['a', 'b']);
+//=> all true
+```
+
+**Invalid patterns**
+
+```js
+isValidGlob();
+isValidGlob('');
+isValidGlob(null);
+isValidGlob(undefined);
+isValidGlob(new Buffer('foo'));
+isValidGlob(['foo', [[]]]);
+isValidGlob(['foo', [['bar']]]);
+isValidGlob(['foo', {}]);
+isValidGlob({});
+isValidGlob([]);
+isValidGlob(['']);
+//=> all false
+```

+# isexe
+
+Minimal module to check if a file is executable, and a normal file.
+
+Uses `fs.stat` and tests against the `PATHEXT` environment variable on
+Windows.
+
+## USAGE
+
+```javascript
+var isexe = require('isexe')
+isexe('some-file-name', function (err, isExe) {
+  if (err) {
+    console.error('probably file does not exist or something', err)
+  } else if (isExe) {
+    console.error('this thing can be run')
+  } else {
+    console.error('cannot be run')
+  }
+})
+
+// same thing but synchronous, throws errors
+var isExe = isexe.sync('some-file-name')
+
+// treat errors as just "not executable"
+isexe('maybe-missing-file', { ignoreErrors: true }, callback)
+var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
+```
+
+## API
+
+### `isexe(path, [options], [callback])`
+
+Check if the path is executable.  If no callback provided, and a
+global `Promise` object is available, then a Promise will be returned.
+
+Will raise whatever errors may be raised by `fs.stat`, unless
+`options.ignoreErrors` is set to true.
+
+### `isexe.sync(path, [options])`
+
+Same as `isexe` but returns the value and throws any errors raised.
+
+### Options
+
+* `ignoreErrors` Treat all errors as "no, this is not executable", but
+  don't raise them.
+* `uid` Number to use as the user id
+* `gid` Number to use as the group id
+* `pathExt` List of path extensions to use instead of `PATHEXT`
+  environment variable on Windows.

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+yaml = require('js-yaml');
+fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  var doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns a JavaScript
+object or throws `YAMLException` on error. By default, does not support regexps,
+functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will call this function with an instance of `YAMLException` for each warning.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+var untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+var yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+output is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
+
+
+Breaking changes in 2.x.x -> 3.x.x
+----------------------------------
+
+If you have not used __custom__ tags or loader classes and not loaded yaml
+files via `require()`, no changes are needed. Just upgrade the library.
+
+Otherwise, you should:
+
+1. Replace all occurrences of `require('xxxx.yml')` by `fs.readFileSync()` +
+  `yaml.safeLoad()`.
+2. rewrite your custom tags constructors and custom loader
+  classes, to conform the new API. See
+  [examples](https://github.com/nodeca/js-yaml/tree/master/examples) and
+  [wiki](https://github.com/nodeca/js-yaml/wiki) for details.

+# json-stable-stringify
+
+This is the same as https://github.com/substack/json-stable-stringify but it doesn't depend on libraries without licenses (jsonify).
+
+deterministic version of `JSON.stringify()` so you can get a consistent hash
+from stringified results
+
+You can also pass in a custom comparison function.
+
+[![browser support](https://ci.testling.com/substack/json-stable-stringify.png)](https://ci.testling.com/substack/json-stable-stringify)
+
+[![build status](https://secure.travis-ci.org/substack/json-stable-stringify.png)](http://travis-ci.org/substack/json-stable-stringify)
+
+# example
+
+``` js
+var stringify = require('json-stable-stringify');
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+console.log(stringify(obj));
+```
+
+output:
+
+```
+{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
+```
+
+# methods
+
+``` js
+var stringify = require('json-stable-stringify')
+```
+
+## var str = stringify(obj, opts)
+
+Return a deterministic stringified string `str` from the object `obj`.
+
+## options
+
+### cmp
+
+If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
+function for object keys. Your function `opts.cmp` is called with these
+parameters:
+
+``` js
+opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
+```
+
+For example, to sort on the object key names in reverse order you could write:
+
+``` js
+var stringify = require('json-stable-stringify');
+
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+var s = stringify(obj, function (a, b) {
+    return a.key < b.key ? 1 : -1;
+});
+console.log(s);
+```
+
+which results in the output string:
+
+```
+{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
+```
+
+Or if you wanted to sort on the object values in reverse order, you could write:
+
+```
+var stringify = require('json-stable-stringify');
+
+var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
+var s = stringify(obj, function (a, b) {
+    return a.value < b.value ? 1 : -1;
+});
+console.log(s);
+```
+
+which outputs:
+
+```
+{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
+```
+
+### space
+
+If you specify `opts.space`, it will indent the output for pretty-printing.
+Valid values are strings (e.g. `{space: \t}`) or a number of spaces
+(`{space: 3}`).
+
+For example:
+
+```js
+var obj = { b: 1, a: { foo: 'bar', and: [1, 2, 3] } };
+var s = stringify(obj, { space: '  ' });
+console.log(s);
+```
+
+which outputs:
+
+```
+{
+  "a": {
+    "and": [
+      1,
+      2,
+      3
+    ],
+    "foo": "bar"
+  },
+  "b": 1
+}
+```
+
+### replacer
+
+The replacer parameter is a function `opts.replacer(key, value)` that behaves
+the same as the replacer
+[from the core JSON object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_native_JSON#The_replacer_parameter).

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of is more correct than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly tests instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+# delimiter-regex [![NPM version](https://badge.fury.io/js/delimiter-regex.svg)](http://badge.fury.io/js/delimiter-regex)  [![Build Status](https://travis-ci.org/jonschlinkert/delimiter-regex.svg)](https://travis-ci.org/jonschlinkert/delimiter-regex) 
+
+> Create regex for template delimiters.
+
+## Install with [npm](npmjs.org)
+
+```bash
+npm i delimiter-regex --save
+```
+
+
+## Usage
+
+```js
+var delims = require('delimiter-regex');
+```
+
+**Example**:
+
+Get a regex for matching front-matter:
+
+```js
+delims('---', '---');
+//=> /---\s*([\s\S]*?)\s*---/
+```
+
+If no args are passed, es6 delimiter regex is returned:
+
+```js
+delims();
+//=> /\$\{\s*([\s\S]*?)\s*\}/
+```
+
+## Params
+
+- **delimiters** `{String|Array}`: supports array format (`delims(['{{', '}}'])`) or list (`delims('{{', '}}')`)
+- **options**: currently RegExp `flags` is the only option
+
+**Flags example**
+
+```js
+delims('{{', '}}', {flags: 'gm'});
+//=> /\{\{([^}}]*)\}\}/gm
+```
+
+## Running tests
+Install dev dependencies.
+
+```bash
+npm i -d && npm test
+```
+

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i layouts --save
+```
+
+## Usage
+
+```js
+var renderLayouts = require('layouts');
+```
+
+## Examples
+
+**Basic example**
+
+In this example, two layouts are used:
+
+* the first layout, `one`, will wrap the string
+* the second layout, `two`, will wrap the first layout
+
+```js
+var layouts = {
+  one: {content: 'one before\n{% body %}\none after', layout: 'two'},
+  two: {content: 'two before\n{% body %}\ntwo after'},
+};
+
+// `one` is the name of the first layout to use on the provided string
+renderLayouts('<div>Wrap me with a layout!!!</div>', 'one', layouts);
+```
+
+Results in:
+
+```html
+two before
+one before
+<div>Wrap me with a layout!!!</div>
+one after
+two after
+```
+
+**HTML**
+
+This example shows how to use nested HTML layouts to wrap content:
+
+```js
+var layouts = {};
+
+layouts.base = {
+  path: 'base.tmpl',
+  content: [
+    '<!DOCTYPE html>',
+    '<html lang="en">',
+    '  <head>',
+    '    <meta charset="UTF-8">',
+    '    <title>Home</title>',
+    '  </head>',
+    '  <body>',
+    '    {% body %}',
+    '  </body>',
+    '</html>',
+  ].join('\n')
+};
+
+// this `nav` layout will be wrapped with the `base` layout
+layouts.nav = {
+  path: 'nav.tmpl',
+  layout: 'base',
+  content: '<nav>\n{% body %}\n</nav>'
+};
+
+// this string will be wrapped with the `nav` layout
+var str = [
+  '<ul class="categories">',
+  '  <li class="active"> <a href="#"> Development </a> </li>',
+  '  <li> <a href="#"> Design </a> </li>',
+  '  <li> <a href="#"> Node.js </a> </li>',
+  '</ul>'
+].join('\n')
+
+// `nav` is the name of the layout to use
+renderLayouts(str, nav, layouts);
+```
+
+Results in something like:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <meta charset="UTF-8">
+    <title>Home</title>
+  </head>
+  <body>
+    <nav>
+      <ul class="categories">
+        <li class="active"> <a href="#"> Development </a> </li>
+        <li> <a href="#"> Design </a> </li>
+        <li> <a href="#"> Node.js </a> </li>
+      </ul>
+    </nav>
+  </body>
+</html>
+```
+
+## Customization
+
+By default, `{% body %}` is used as the placeholder (insertion point) for content, but this can easily be customized with the following options:
+
+* `layoutDelims`: the delimiters to use. This can be a regex, like `/\{{([^}]+)\}}/`, or an array of delimiter strings, like `['{{', '}}']`
+* `tag`: the name of the placeholder tag.
+
+## API
+
+### [renderLayouts](index.js#L37)
+
+Wrap one or more layouts around `string`.
+
+**Params**
+
+* `string` **{String}**: The string to wrap with a layout.
+* `layoutName` **{String}**: The name (key) of the layout object to use.
+* `layouts` **{Object}**: Object of layout objects.
+* `options` **{Object}**: Optionally define a `defaultLayout` (string), pass custom delimiters (`layoutDelims`) to use as the placeholder for the content insertion point, or change the name of the placeholder tag with the `tag` option.
+* `fn` **{Function}**: Optionally pass a function to modify the context as each layout is applied.
+* `returns` **{String}**: Returns the original string wrapped with one or more layouts.
+
+**Example**
+
+```js
+renderLayouts(string, layoutName, layouts, options, fn);
+```
+
+## History
+
+**v0.11.0**
+
+* All view objects must now have a `path` property, following [vinyl](http://github.com/gulpjs/vinyl) conventions.

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+# Lazy Streams
+
+> *Create streams lazily when they are read from or written to.*  
+> `lazystream: 1.0.0` [![Build Status](https://travis-ci.org/jpommerening/node-lazystream.png?branch=master)](https://travis-ci.org/jpommerening/node-lazystream)  
+
+## Why?
+
+Sometimes you feel the itch to open *all the files* at once. You want to pass a bunch of streams around, so the consumer does not need to worry where the data comes from.
+From a software design point-of-view this sounds entirely reasonable. Then there is that neat little function `fs.createReadStream()` that opens a file and gives you a nice `fs.ReadStream` to pass around, so you use what the mighty creator deities of node bestowed upon you.
+
+> `Error: EMFILE, too many open files`  
+> ─ *node*
+
+This package provides two classes based on the node's Streams3 API (courtesy of `readable-stream` to ensure a stable version).
+
+## Class: lazystream.Readable
+
+A wrapper for readable streams. Extends [`stream.PassThrough`](http://nodejs.org/api/stream.html#stream_class_stream_passthrough).
+
+### new lazystream.Readable(fn [, options])
+
+* `fn` *{Function}*  
+  The function that the lazy stream will call to obtain the stream to actually read from.
+* `options` *{Object}*  
+  Options for the underlying `PassThrough` stream, accessible by `fn`.
+
+Creates a new readable stream. Once the stream is accessed (for example when you call its `read()` method, or attach a `data`-event listener) the `fn` function is called with the outer `lazystream.Readable` instance bound to `this`.
+
+If you pass an `options` object to the constuctor, you can access it in your `fn` function.
+
+```javascript
+new lazystream.Readable(function (options) {
+  return fs.createReadStream('/dev/urandom');
+});
+```
+
+## Class: lazystream.Writable
+
+A wrapper for writable streams. Extends [`stream.PassThrough`](http://nodejs.org/api/stream.html#stream_class_stream_passthrough).
+
+### new lazystream.Writable(fn [, options])
+
+* `fn` *{Function}*  
+  The function that the lazy stream will call to obtain the stream to actually write to.
+* `options` *{Object}*  
+  Options for the underlying `PassThrough` stream, accessible by `fn`.
+
+Creates a new writable stream. Just like the one above but for writable streams.
+
+```javascript
+new lazystream.Writable(function () {
+  return fs.createWriteStream('/dev/null');
+});
+```
+
+## Install
+
+```console
+$ npm install lazystream --save

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save matched
+```
+
+## Usage
+
+If non-glob patterns (e.g. file paths) are passed, only paths that exist on the file system are returned.
+
+```js
+var glob = require('matched');
+```
+
+**async**
+
+```js
+glob(['*.js'], function(err, files) {
+  //=> ['utils.js', 'index.js']
+});
+```
+
+**sync**
+
+```js
+var files = glob.sync(['*.js']);
+//=> ['utils.js', 'index.js']
+```
+
+**promise**
+
+```js
+glob.promise(['*.txt'])
+  .then(function(files) {
+    //=> ['a.txt', 'b.txt', 'c.txt']
+  });
+```
+
+**options**
+
+All methods take options as the second argument:
+
+```js
+glob(['*.js'], {cwd: 'test'}, function(err, files) {
+  //=> ['test.js']
+});
+```
+
+## Release history
+
+**v0.4.1**
+
+* Exposes a non-enumerable `cache` property on the returned files array. This is a patch relase since the property does not change the existing API and should not otherwise effect behavior or results.
+

+
+> Loads the package.json from the root of the user's current project.
+
+**HEADS UP!**
+
+Breaking changes in v2.0. The main export is now a function that must be called. This is so that the package.json is lazily loaded when the function is called.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i load-pkg --save
+```
+
+## async usage
+
+```js
+var loadPkg = require('load-pkg');
+
+// get the package.json from the cwd
+loadPkg(function(err, pkg) {
+  console.log(pkg.name);
+  //=> 'load-pkg'
+});
+
+// get the package.json from the specified directory
+loadPkg('~/foo/bar', function(err, pkg) {
+  console.log(pkg.name);
+  //=> 'load-pkg'
+});
+```
+
+## sync usage
+
+```js
+var pkg = require('load-pkg').sync(process.cwd());
+console.log(pkg.name);
+//=> 'load-pkg'
+```
+
+Specify the cwd or filepath to start from:
+
+```js
+var pkg = require('load-pkg').sync('a/b/c');
+console.log(pkg.name);
+//=> 'foo'
+```
+
+## Related projects

+* [find-pkg](https://www.npmjs.com/package/find-pkg): Find the first directory with a package.json, recursing up, starting with the given directory. | [homepage](https://github.com/jonschlinkert/find-pkg)
+* [look-up](https://www.npmjs.com/package/look-up): Faster drop-in replacement for find-up and findup-sync. | [homepage](https://github.com/jonschlinkert/look-up)

+## Running tests
+
+Install dev dependencies:
+
+```sh
+$ npm i -d && npm test
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+# is-glob [![NPM version](https://badge.fury.io/js/is-glob.svg)](http://badge.fury.io/js/is-glob)  [![Build Status](https://travis-ci.org/jonschlinkert/is-glob.svg)](https://travis-ci.org/jonschlinkert/is-glob)
+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save matched
+```
+
+## Usage
+
+If non-glob patterns (e.g. file paths) are passed, only paths that exist on the file system are returned.
+
+```js
+var glob = require('matched');
+```
+
+**async**
+
+```js
+glob(['*.js'], function(err, files) {
+  //=> ['utils.js', 'index.js']
+});
+```
+
+**sync**
+
+```js
+var files = glob.sync(['*.js']);
+//=> ['utils.js', 'index.js']
+```
+
+**promise**
+
+```js
+glob.promise(['*.txt'])
+  .then(function(files) {
+    //=> ['a.txt', 'b.txt', 'c.txt']
+  });
+```
+
+**options**
+
+All methods take options as the second argument:
+
+```js
+glob(['*.js'], {cwd: 'test'}, function(err, files) {
+  //=> ['test.js']
+});
+```
+
+## Release history
+
+**v0.4.1**
+
+* Exposes a non-enumerable `cache` property on the returned files array. This is a patch relase since the property does not change the existing API and should not otherwise effect behavior or results.
+

+
+Lower case a string.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install lower-case --save
+```
+
+## Usage
+
+```js
+var lowerCase = require('lower-case')
+
+lowerCase(null)           //=> ""
+lowerCase('STRING')       //=> "string"
+lowerCase('STRING', 'tr') //=> "strıng"
+
+lowerCase({ toString: function () { return 'TEST' } }) //=> "test"
+```

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+# map-config [![NPM version](https://img.shields.io/npm/v/map-config.svg)](https://www.npmjs.com/package/map-config) [![Build Status](https://img.shields.io/travis/doowb/map-config.svg)](https://travis-ci.org/doowb/map-config)
+
+> Map configuration objects to application methods.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i map-config --save
+```
+
+## Usage
+
+```js
+var MapConfig = require('map-config');
+```
+
+## API
+
+### [MapConfig](index.js#L24)
+Create a new instance of MapConfig with a specified map and application.
+
+**Params**
+
+* `app` **{Object}**: Object containing the methods that will be called based on the map specification.    
+* `map` **{Object}**: Optional object specifying how to map a configuration to an application.    
+
+**Example**
+
+```js
+var mapper = new MapConfig(app, map);
+```
+
+### [.map](index.js#L63)
+Map properties to methods and/or functions.
+
+**Params**
+
+* `key` **{String}**: property key to map.    
+* `val` **{Function|Object}**: Optional function to call when a config has the given key. Functions will be passed `(val, key, config)` when called. Functions may also take a callback to indicate async usage. May also pass another instance of MapConfig to be processed.    
+* `returns` **{Object}** `this`: to enable chaining  
+
+**Example**
+
+```js
+mapper
+  .map('baz')
+  .map('bang', function(val, key, config) {
+  });
+```
+
+### [.alias](index.js#L122)
+Create an `alias` for property `key`.
+
+**Params**
+
+* `alias` **{String}**: Alias to use for `key`.    
+* `key` **{String}**: Actual property or method on `app`.    
+* `returns` **{Object}**: Returns the instance for chaining.  
+
+**Example**
+
+```js
+mapper.alias('foo', 'bar');
+```
+
+### [.process](index.js#L143)
+Process a configuration object with the already configured `map` and `app`.
+
+**Params**
+
+* `config` **{Object}**: Configuration object to map to application methods.    
+* `cb` **{Function}**: Optional callback function that will be called when finished or if an error occurs during processing.    
+
+**Example**
+
+```js
+mapper.process(config);
+```
+
+### [.addKey](index.js#L217)
+Add a key to the `.keys` array. May also be used to add an array of namespaced keys to the `.keys` array. Useful for mapping "sub-configs" to a key in a parent config.
+
+**Params**
+
+* `key` **{String}**: key to push onto `.keys`    
+* `arr` **{Array}**: Array of sub keys to push onto `.keys`    
+* `returns` **{Object}** `this`: for chaining  
+
+**Example**
+
+```js
+mapper.addKey('foo');
+console.log(mapper.keys);
+//=> ['foo']
+
+var one = new MapConfig();
+var two = new MapConfig();
+two.map('foo');
+two.map('bar');
+two.map('baz');
+
+// map config `two` to config `one`
+one.map('two', function(val, key, config, next) {
+  two.process(val, next);
+});
+
+// map keys from config `two` to config `one`
+one.addKey('two', two.keys);
+console.log(one.keys);
+//=> ['two.foo', 'two.bar', 'two.baz']
+```

+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## Assign or Merge vs. Visit
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend`:
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. But **if you also want to emit an event** each time a property is added to the `data` object. A better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach, when an array is passed to `set`, `mapVisit` calls `set` on each object in the array. When an object is passed, `visit` calls `set` on each property in the object. As a result, the `data` event will be emitted every time a property is added to `data`.
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // some event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-schema
+```
+
+## Usage
+
+```js
+var schema = require('map-schema');
+```
+
+**Example**
+
+This is a basic example schema for normalizing and validating fields on `package.json` (a full version of this will be available on [normalize-pkg](https://github.com/jonschlinkert/normalize-pkg) when complete):
+
+```js
+var fs = require('fs');
+var isObject = require('isobject');
+var Schema = require('map-schema');
+
+// create a schema
+var schema = new Schema()
+  .field('name', 'string')
+  .field('description', 'string')
+  .field('repository', ['object', 'string'], {
+    normalize: function(val) {
+      return isObject(val) ? val.url : val;
+    }
+  })
+  .field('main', 'string', {
+    validate: function(filepath) {
+      return fs.existsSync(filepath);
+    }
+  })
+  .field('version', 'string', {
+    default: '0.1.0'
+  })
+  .field('license', 'string', {
+    default: 'MIT'
+  })
+
+var pkg = require('./package');
+// normalize an object
+console.log(schema.normalize(pkg));
+// validation errors array
+console.log(schema.errors);
+```
+
+**Errors**
+
+Validation errors are exposed on `schema.errors`. Error reporting is pretty basic right now but I plan to implement something better soon.
+
+## API
+
+### [Schema](index.js#L44)
+
+Create a new `Schema` with the given `options`.
+
+**Params**
+
+* `options` **{Object}**
+
+**Example**
+
+```js
+var schema = new Schema()
+  .field('name', 'string')
+  .field('version', 'string')
+  .field('license', 'string')
+  .field('licenses', 'array', {
+    normalize: function(val, key, config) {
+       // convert license array to `license` string
+       config.license = val[0].type;
+       delete config[key];
+    }
+  })
+  .normalize(require('./package'))
+```
+
+### [.set](index.js#L84)
+
+Set `key` on the instance with the given `value`.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{Object}**
+
+### [.warning](index.js#L101)
+
+Push a warning onto the `schema.warnings` array. Placeholder for
+better message handling and a reporter (planned).
+
+**Params**
+
+* `method` **{String}**: The name of the method where the warning is recorded.
+* `prop` **{String}**: The name of the field for which the warning is being created.
+* `message` **{String}**: The warning message.
+* `value` **{String}**: The value associated with the warning.
+* `returns` **{any}**
+
+### [.field](index.js#L133)
+
+Add a field to the schema with the given `name`, `type` or types, and options.
+
+**Params**
+
+* `name` **{String}**
+* `type` **{String|Array}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+var semver = require('semver');
+
+schema
+  .field('keywords', 'array')
+  .field('version', 'string', {
+    validate: function(val, key, config, schema) {
+      return semver.valid(val) !== null;
+    }
+  })
+```
+
+### [.get](index.js#L193)
+
+Get field `name` from the schema. Get a specific property from the field by passing the property name as a second argument.
+
+**Params**
+
+* `name` **{Strign}**
+* `prop` **{String}**
+* `returns` **{Object|any}**: Returns the field instance or the value of `prop` if specified.
+
+**Example**
+
+```js
+schema.field('bugs', ['object', 'string']);
+var field = schema.get('bugs', 'types');
+//=> ['object', 'string']
+```
+
+### [.omit](index.js#L206)
+
+Omit a property from the returned object. This method can be used
+in normalize functions as a way of removing undesired properties.
+
+**Params**
+
+* `key` **{String}**: The property to remove
+* `returns` **{Object}**: Returns the instance for chaining.
+
+### [.update](index.js#L237)

+
+* `config` **{Object}**
+* `returns` **{Array}**
+
+### [.sortObject](index.js#L342)
+
+If a `keys` array is passed on the constructor options, or as a second argument to `sortObject`, this sorts the given object so that keys are in the same order as the supplied array of `keys`.
+
+**Params**
+
+* `config` **{Object}**
+* `returns` **{Object}**: Returns the config object with keys sorted to match the given array of keys.
+
+**Example**

+
+> Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## What does this do?
+
+**Assign/Merge/Extend vs. Visit**
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend` (comparable to `Object.assign`):
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. However, **if you also want to emit an event** each time a property is added to the `data` object, or you want more control over what happens as the object is extended, a better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach:
+
+* when an array is passed to `set`, the `mapVisit` library calls the `set` method on each object in the array.
+* when an object is passed, `visit` calls `set` on each property in the object.
+
+As a result, the `data` event will be emitted every time a property is added to `data` (events are just an example, you can use this approach to perform any necessary logic every time the method is called).
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // simulate an event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+
+> Returns true when the given `name` matches any of the path properties on a vinyl file.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save match-file
+```
+
+## Usage
+
+```js
+var matchFile = require('match-file');
+```
+
+## API
+
+### matchFile
+
+Returns true if the given string matches one of the path properties on the `file` object (does not match agains `file.extname` only)
+
+```js
+var File = require('vinyl');
+var matchFile = require('match-file');
+
+var file = new File({path: 'a/b/c.txt', base: 'a'});
+var isMatch = matchFile('c.txt', file);
+//=> true (since `c.txt` matches file.basename)
+```
+
+**Examples**
+
+Continuing with the above setup code, all of the following would return `true`:
+
+```js
+// file.path
+matchFile('a/b/c.txt', file);
+// file.relative
+matchFile('b/c.txt', file);
+// file.basename
+matchFile('c.txt', file);
+// file.stem
+matchFile('c', file);
+```
+
+### .isMatch
+
+Similar to `matchFile`, but **also supports glob patterns** for matching. [micromatch](https://github.com/jonschlinkert/micromatch) is used for matching, visit that project to see all available features and options.
+
+```js
+var file = new File({path: 'a/b/c.txt'});
+console.log(matcher.isMatch('*.js', file));
+//=> false
+
+var file = new File({path: 'a/b/c.js'});
+console.log(matcher.isMatch('*.js', file));
+//=> true
+```
+
+#### Examples
+
+```js
+var File = require('vinyl');
+var matchFile = require('match-file');
+
+var file = new File({path: 'a/b/c/d/e.txt', base: 'a/b/c'});
+file.key = 'zzz/a.txt'; // arbitrary key (for caching)
+```
+
+```js
+// file.path
+console.log(matchFile.isMatch('a/b/c/d/e.txt', file));
+// file.relative
+console.log(matchFile.isMatch('d/e.txt', file));
+// file.basename
+console.log(matchFile.isMatch('e.txt', file));
+// file.stem
+console.log(matchFile.isMatch('e', file));
+// file.key
+console.log(matchFile.isMatch('zzz/a.txt', file));
+// glob pattern for `file.path`
+console.log(matchFile.isMatch('**/*.txt', file));
+// glob pattern for `file.relative`
+console.log(matchFile.isMatch('d/*.txt', file));
+// glob pattern for `file.stem`
+console.log(matchFile.isMatch('*', file));
+// glob pattern for `file.basename`
+console.log(matchFile.isMatch('*.txt', file));
+```
+
+### .matcher
+
+Returns a matcher function bound to the given glob `patterns` and `options`. [micromatch](https://github.com/jonschlinkert/micromatch) is used for matching, visit that project to see all available features and options.
+
+```js
+var isMatch = matchFile.matcher('*.js');
+console.log(isMatch);
+//=> [function]
+
+var file = new File({path: 'a/b/c.txt'});
+console.log(isMatch(file));
+//=> false
+
+var file = new File({path: 'a/b/c.js'});
+console.log(isMatch(file));
+//=> true
+```
+
+#### Examples
+
+Given this setup code:
+
+```js
+var File = require('vinyl');
+var matchFile = require('match-file');
+
+var file = new File({path: 'a/b/c/d/e.txt', base: 'a/b/c'});
+file.key = 'zzz/a.txt'; // arbitrary key (for caching)
+```
+
+All of the following examples would return `true`:
+
+```js
+// file.path
+var isMatch = matchFile.matcher('a/b/c/d/e.txt');
+console.log(isMatch(file));
+// file.relative
+var isMatch = matchFile.matcher('d/e.txt');
+console.log(isMatch(file));
+// file.basename
+var isMatch = matchFile.matcher('e.txt');
+console.log(isMatch(file));

+var though = require('though2');
+var gulp = require('gulp');
+
+gulp.task('example', function() {
+  return gulp.src('src/**/*')
+    .pipe(filter('*.js'));
+});
+
+function filter(pattern, options) {
+  // define a matcher function outside of the plugin function
+  var isMatch = matchFile.matcher(pattern, options);
+
+  return through.obj(function(file, enc, next) {
+    // use the matcher function
+    if (isMatch(file)) {
+      next(null, file);
+      return;
+    }
+    next();
+  });

+
+> Adds array support to node-glob, sync and async. Also supports tilde expansion (user home) and resolving to global npm modules.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save matched
+```
+
+## Usage
+
+If non-glob patterns (e.g. file paths) are passed, only paths that exist on the file system are returned.
+
+```js
+var glob = require('matched');
+```
+
+**async**
+
+```js
+glob(['*.js'], function(err, files) {
+  //=> ['utils.js', 'index.js']
+});
+```
+
+**sync**
+
+```js
+var files = glob.sync(['*.js']);
+//=> ['utils.js', 'index.js']
+```
+
+**promise**
+
+```js
+glob.promise(['*.txt'])
+  .then(function(files) {
+    //=> ['a.txt', 'b.txt', 'c.txt']
+  });
+```
+
+**options**
+
+All methods take options as the second argument:
+
+```js
+glob(['*.js'], {cwd: 'test'}, function(err, files) {
+  //=> ['test.js']
+});
+```
+
+## Release history
+
+### v1.0.0
+
+* Minor code improvements, dependency upgrades
+
+### v0.4.1
+
+* Exposes a non-enumerable `cache` property on the returned files array. This is a patch relase since the property does not change the existing API and should not otherwise effect behavior or results.

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+
+> Returns `true` if an array has a glob pattern.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save has-glob
+```
+
+## Usage
+
+```js
+var hasGlob = require('has-glob');
+
+hasGlob(['foo', 'bar', '*.js']);
+//=> true
+
+hasGlob(['foo', 'bar', 'baz']);
+//=> false
+```
+
+**True**
+
+The following all return `true`:
+
+```js
+hasGlob(['foo', 'bar', '*.js'])
+hasGlob(['foo', 'bar', '!*.js'])
+hasGlob(['foo', 'bar', '!foo'])
+hasGlob(['foo', 'bar', '!foo.js'])
+hasGlob(['foo', 'bar', '**/abc.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/{a,b}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z}.js'])
+hasGlob(['foo', 'bar', 'abc/{a..z..2}.js'])
+hasGlob(['foo', 'bar', 'abc/@(a).js'])
+hasGlob(['foo', 'bar', 'abc/!(a).js'])
+hasGlob(['foo', 'bar', 'abc/+(a).js'])
+hasGlob(['foo', 'bar', 'abc/*(a).js'])
+hasGlob(['foo', 'bar', 'abc/?(a).js'])
+hasGlob(['foo', 'bar', 'abc/@.js'])
+hasGlob(['foo', 'bar', 'abc/!.js'])
+hasGlob(['foo', 'bar', 'abc/+.js'])
+hasGlob(['foo', 'bar', 'abc/*.js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', 'abc/(aaa|bbb).js'])
+hasGlob(['foo', 'bar', 'abc/?.js'])
+hasGlob(['foo', 'bar', '?.js'])
+hasGlob(['foo', 'bar', '[abc].js'])
+hasGlob(['foo', 'bar', '[^abc].js'])
+hasGlob(['foo', 'bar', 'a/b/c/[a-z].js'])
+hasGlob(['foo', 'bar', '[a-j]*[^c]b/c'])
+//=> true
+```
+
+Also works with strings:
+
+```js
+hasGlob('*.js')
+hasGlob('!*.js')
+hasGlob('!foo')
+hasGlob('!foo.js')
+hasGlob('**/abc.js')
+hasGlob('abc/*.js')
+//=> true
+```
+
+**False**
+
+The following all return `false`:
+
+```js
+hasGlob([])
+hasGlob([null])
+hasGlob([undefined])
+hasGlob([{}])
+hasGlob(['.'])
+hasGlob(['foo', 'bar', 'aa'])
+hasGlob(['foo', 'bar', 'abc.js'])
+hasGlob(['foo', 'bar', 'abc/def/ghi.js'])
+//=> false
+```

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-glob
+```
+
+## Usage
+
+This really just checks to make sure that a pattern is either a string or array, and if it's an array it's either empty or consists of only strings.
+
+```js
+var isValidGlob = require('is-valid-glob');
+
+isValidGlob('foo/*.js');
+//=> true
+```
+
+**Valid patterns**
+
+```js
+isValidGlob('a');
+isValidGlob('a.js');
+isValidGlob('*.js');
+isValidGlob(['a', 'b']);
+//=> all true
+```
+
+**Invalid patterns**
+
+```js
+isValidGlob();
+isValidGlob('');
+isValidGlob(null);
+isValidGlob(undefined);
+isValidGlob(new Buffer('foo'));
+isValidGlob(['foo', [[]]]);
+isValidGlob(['foo', [['bar']]]);
+isValidGlob(['foo', {}]);
+isValidGlob({});
+isValidGlob([]);
+isValidGlob(['']);

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# merge-stream
+
+Merge (interleave) a bunch of streams.
+
+[![build status](https://secure.travis-ci.org/grncdr/merge-stream.svg?branch=master)](http://travis-ci.org/grncdr/merge-stream)
+
+## Synopsis
+
+```javascript
+var stream1 = new Stream();
+var stream2 = new Stream();
+
+var merged = mergeStream(stream1, stream2);
+
+var stream3 = new Stream();
+merged.add(stream3);
+merged.isEmpty();
+//=> false
+```
+
+## Description
+
+This is adapted from [event-stream](https://github.com/dominictarr/event-stream) separated into a new module, using Streams3.
+
+## API
+
+### `mergeStream`
+
+Type: `function`
+
+Merges an arbitrary number of streams. Returns a merged stream.
+
+#### `merged.add`
+
+A method to dynamically add more sources to the stream. The argument supplied to `add` can be either a source or an array of sources.
+
+#### `merged.isEmpty`
+
+A method that tells you if the merged stream is empty.
+
+When a stream is "empty" (aka. no sources were added), it could not be returned to a gulp task.
+
+So, we could do something like this:
+
+```js
+stream = require('merge-stream')();
+// Something like a loop to add some streams to the merge stream
+// stream.add(streamA);
+// stream.add(streamB);
+return stream.isEmpty() ? null : stream;
+```

+> Similar to assign-value but deeply merges object values or nested values using object path/dot notation.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save merge-value
+```
+
+## Usage
+
+```js
+var merge = require('merge-value');
+
+var obj = {};
+merge(obj, 'foo', {a: 'b'})
+//=> obj.foo ==> {a: 'b'}
+
+var obj = {foo: {a: 'b'}};
+merge(obj, 'foo', {c: 'd'})
+//=> obj.foo ==> {a: 'b', c: 'd'}
+
+var obj = {};
+merge(obj, 'a.b.c', {one: 'two'});
+merge(obj, 'a.b.c', {three: 'four'});
+//=> obj.a.b.c ==> {one: 'two', three: 'four'}
+
+var obj = {foo: {bar: {baz: {a: 'b'}}}};
+merge(obj, 'foo', {bar: {baz: {c: 'd'}}});
+//=> {foo: {bar: {baz: {a: 'b', c: 'd'}}}}

+
+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable

+
+> Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save set-value
+```
+
+## Usage
+
+```js
+var set = require('set-value');
+set(object, prop, value);
+```
+
+### Params
+
+* `object` **{object}**: The object to set `value` on
+* `prop` **{string}**: The property to set. Dot-notation may be used.
+* `value` **{any}**: The value to set on `object[prop]`
+
+## Examples
+
+Updates and returns the given object:
+
+```js
+var obj = {};
+set(obj, 'a.b.c', 'd');
+console.log(obj);
+//=> { a: { b: { c: 'd' } } }
+```
+
+### Escaping
+
+**Escaping with backslashes**
+
+Prevent set-value from splitting on a dot by prefixing it with backslashes:
+
+```js
+console.log(set({}, 'a\\.b.c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, 'a\\.b\\.c', 'd'));
+//=> { 'a.b.c': 'd' }
+```
+
+**Escaping with double-quotes or single-quotes**
+
+Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:
+
+```js
+console.log(set({}, '"a.b".c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, "'a.b'.c", "d"));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, '"this/is/a/.file.path"', 'd'));
+//=> { 'this/is/a/file.path': 'd' }
+```
+
+### Bracket support
+
+set-value does not split inside brackets or braces:
+
+```js
+console.log(set({}, '[a.b].c', 'd'));
+//=> { '[a.b]': { c: 'd' } }
+
+console.log(set({}, "(a.b).c", "d"));
+//=> { '(a.b)': { c: 'd' } }
+
+console.log(set({}, "<a.b>.c", "d"));
+//=> { '<a.b>': { c: 'd' } }
+
+console.log(set({}, "{a..b}.c", "d"));
+//=> { '{a..b}': { c: 'd' } }
+```
+
+## History
+
+### v2.0.0
+
+* Adds support for escaping with double or single quotes. See [escaping](#escaping) for examples.
+* Will no longer split inside brackets or braces. See [bracket support](#bracket-support) for examples.
+
+If there are any regressions please create a [bug report](../../issues/new). Thanks!

+# is-extendable [![NPM version](https://badge.fury.io/js/is-extendable.svg)](http://badge.fury.io/js/is-extendable)
+
+> Returns true if a value is any of the object types: array, regexp, plain object, function or date. This is useful for determining if a value can be extended, e.g. "can the value have keys?"
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-extendable --save
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* `array`
+* `regexp`
+* `plain object`
+* `function`
+* `date`
+* `error`
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is an `object`, `function`
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Related projects
+
+* [assign-deep](https://github.com/jonschlinkert/assign-deep): Deeply assign the enumerable properties of source objects to a destination object.
+* [extend-shallow](https://github.com/jonschlinkert/extend-shallow): Extend an object with the properties of additional objects. node.js/javascript util.
+* [isobject](https://github.com/jonschlinkert/isobject): Returns true if the value is an object and not an array or null.
+* [is-plain-object](https://github.com/jonschlinkert/is-plain-object): Returns true if an object was created by the `Object` constructor.
+* [is-equal-shallow](https://github.com/jonschlinkert/is-equal-shallow): Does a shallow comparison of two objects, returning false if the keys or values differ.
+* [kind-of](https://github.com/jonschlinkert/kind-of): Get the native type of a value.
+
+## Running tests
+
+Install dev dependencies:
+
+```sh
+$ npm i -d && npm test
+```

+
+> Glob matching for javascript/node.js. A drop-in replacement and faster alternative to minimatch and multimatch.
+
+Micromatch supports all of the same matching features as [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch).
+
+* [mm()](#usage) is the same as [multimatch()](https://github.com/sindresorhus/multimatch)
+* [mm.match()](#match) is the same as [minimatch.match()](https://github.com/isaacs/minimatch)
+* use [mm.isMatch()](#ismatch) instead of [minimatch()](https://github.com/isaacs/minimatch)
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save micromatch
+```
+
+## Start matching!
+
+```js
+var mm = require('micromatch');
+console.log(mm(['']))
+```
+
+***
+
+### Features
+
+* [Drop-in replacement](#switch-from-minimatch) for [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch)
+* Built-in support for multiple glob patterns, like `['foo/*.js', '!bar.js']`
+* [Brace Expansion](https://github.com/jonschlinkert/braces) (`foo/bar-{1..5}.md`, `one/{two,three}/four.md`)
+* Typical glob patterns, like `**/*`, `a/b/*.js`, or `['foo/*.js', '!bar.js']`
+* Methods like `.isMatch()`, `.contains()` and `.any()`
+
+**Extended globbing features:**
+
+* Logical `OR` (`foo/bar/(abc|xyz).js`)
+* Regex character classes (`foo/bar/baz-[1-5].js`)
+* POSIX [bracket expressions](https://github.com/jonschlinkert/expand-brackets) (`**/[[:alpha:][:digit:]]/`)
+* [extglobs](https://github.com/jonschlinkert/extglob) (`**/+(x|y)`, `!(a|b)`, etc).
+
+You can combine these to create whatever matching patterns you need.
+
+**Example**
+
+```js
+// double-negation!
+mm(['fa', 'fb', 'f', 'fo'], '!(f!(o))');
+//=> ['fo']
+```
+
+## Why switch to micromatch?
+
+* Native support for multiple glob patterns, no need for wrappers like [multimatch](https://github.com/sindresorhus/multimatch)
+* [10-55x faster](#benchmarks) and more performant than [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch). This is achieved through a combination of caching and regex optimization strategies, a fundamentally different approach than minimatch.
+* More extensive support for the Bash 4.3 specification
+* More complete extglob support
+* Extensive [unit tests](./test) (approx. 1,300 tests). Minimatch fails many of the tests.
+
+### Switch from minimatch
+
+Use `mm.isMatch()` instead of `minimatch()`:
+
+```js
+mm.isMatch('foo', 'b*');
+//=> false
+```
+
+Use `mm.match()` instead of `minimatch.match()`:
+
+```js
+mm.match(['foo', 'bar'], 'b*');
+//=> 'bar'
+```
+
+### Switch from multimatch
+
+Same signature:
+
+```js
+mm(['foo', 'bar', 'baz'], ['f*', '*z']);
+//=> ['foo', 'baz']
+```
+
+***
+
+## Usage
+
+Add micromatch to your node.js project:
+
+```js
+var mm = require('micromatch');
+```
+
+**Signature**
+
+```js
+mm(array_of_strings, glob_patterns[, options]);
+```
+
+**Example**
+
+```js
+mm(['foo', 'bar', 'baz'], 'b*');
+//=> ['bar', 'baz']
+```
+
+### Usage examples
+
+**Brace expansion**
+
+Match files with `.js` or `.txt` extensions.
+
+```js
+mm(['a.js', 'b.md', 'c.txt'], '*.{js,txt}');
+//=> ['a.js', 'c.txt']
+```
+
+**Extglobs**
+
+Match anything except for files with the `.md` extension.
+
+```js
+mm(files, '**/*.!(md)');
+
+//=> ['a.js', 'c.txt']
+```
+
+**Multiple patterns**
+
+Match using an array of patterns.
+
+```js
+mm(['a.md', 'b.js', 'c.txt', 'd.json'], ['*.md', '*.txt']);
+//=> ['a.md', 'c.txt']
+```
+
+**Negation patterns:**
+
+Behavior is designed to be what users would expect, based on conventions that are already well-established.
+
+* [minimatch](https://github.com/isaacs/minimatch) behavior is used when the pattern is a string, so patterns are **inclusive by default**.
+* [multimatch](https://github.com/sindresorhus/multimatch) behavior is used when an array of patterns is passed, so patterns are **exclusive by default**.
+
+```js
+mm(['a.js', 'b.md', 'c.txt'], '!*.{js,txt}');
+//=> ['b.md']
+
+mm(['a.md', 'b.js', 'c.txt', 'd.json'], ['*.*', '!*.{js,txt}']);
+//=> ['a.md', 'd.json']
+```
+
+***
+
+## API methods
+
+```js
+var mm = require('micromatch');
+```
+
+### .match
+
+```js
+mm.match(array, globString);
+```
+
+Return an array of files that match the given glob pattern. Useful if you only need to use a single glob pattern.
+
+**Example**
+
+```js
+mm.match(['ab', 'a/b', 'bb', 'b/c'], '?b');
+//=> ['ab', 'bb']
+
+mm.match(['ab', 'a/b', 'bb', 'b/c'], '*/b');
+//=> ['a/b']
+```
+
+### .isMatch
+
+```js
+mm.isMatch(filepath, globString);
+```
+
+Returns true if a file path matches the given glob pattern.
+
+**Example**
+
+```js
+mm.isMatch('.verb.md', '*.md');
+//=> false
+
+mm.isMatch('.verb.md', '*.md', {dot: true});
+//=> true
+```
+
+### .contains
+
+Returns true if any part of a file path matches the given glob pattern. Think of this is "has path" versus "is path".
+
+**Example**
+
+`.isMatch()` would return false for both of the following:
+
+```js
+mm.contains('a/b/c', 'a/b');
+//=> true
+
+mm.contains('a/b/c', 'a/*');
+//=> true
+```
+
+### .matcher
+
+Returns a function for matching using the supplied pattern. e.g. create your own "matcher". The advantage of this method is that the pattern can be compiled outside of a loop.
+
+**Pattern**
+
+Can be any of the following:
+
+* `glob/string`
+* `regex`
+* `function`
+
+**Example**
+
+```js
+var isMatch = mm.matcher('*.md');
+var files = [];
+
+['a.md', 'b.txt', 'c.md'].forEach(function(fp) {
+  if (isMatch(fp)) {
+    files.push(fp);
+  }
+});
+```
+
+### .filter
+
+Returns a function that can be passed to `Array#filter()`.
+
+**Params**
+
+* `patterns` **{String|Array}**:
+
+**Examples**
+
+Single glob:
+
+```js
+var fn = mm.filter('*.md');
+['a.js', 'b.txt', 'c.md'].filter(fn);
+//=> ['c.md']
+
+var fn = mm.filter('[a-c]');
+['a', 'b', 'c', 'd', 'e'].filter(fn);
+//=> ['a', 'b', 'c']
+```
+
+Array of glob patterns:
+
+```js
+var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];
+
+var fn = mm.filter(['{1..10}', '![7-9]', '!{3..4}']);
+arr.filter(fn);
+//=> [1, 2, 5, 6, 10]
+```
+
+_(Internally this function generates the matching function by using the [matcher](#matcher) method. You can use the [matcher](#matcher) method directly to create your own filter function)_
+
+### .any
+
+Returns true if a file path matches any of the given patterns.
+
+```js
+mm.any(filepath, patterns, options);
+```
+
+**Params**
+
+* filepath `{String}`: The file path to test.
+* patterns `{String|Array}`: One or more glob patterns
+* options: `{Object}`: options to pass to the `.matcher()` method.
+
+**Example**
+
+```js
+mm.any('abc', ['!*z']);
+//=> true
+mm.any('abc', ['a*', 'z*']);
+//=> true
+mm.any('abc', 'a*');
+//=> true
+mm.any('abc', ['z*']);
+//=> false
+```
+
+### .expand
+
+Returns an object with a regex-compatible string and tokens.
+
+```js
+mm.expand('*.js');
+
+// when `track` is enabled (for debugging), the `history` array is used
+// to record each mutation to the glob pattern as it's converted to regex
+{ options: { track: false, dot: undefined, makeRe: true, negated: false },
+  pattern: '(.*\\/|^)bar\\/(?:(?!(?:^|\\/)\\.).)*?',
+  history: [],
+  tokens:
+   { path:
+      { whole: '**/bar/**',
+        dirname: '**/bar/',
+        filename: '**',
+        basename: '**',
+        extname: '',
+        ext: '' },
+     is:
+      { glob: true,
+        negated: false,
+        globstar: true,
+        dotfile: false,
+        dotdir: false },
+     match: {},
+     original: '**/bar/**',
+     pattern: '**/bar/**',
+     base: '' } }
+```
+
+### .makeRe
+
+Create a regular expression for matching file paths based on the given pattern:
+
+```js
+mm.makeRe('*.js');
+//=> /^(?:(?!\.)(?=.)[^/]*?\.js)$/
+```
+
+## Options
+

+***
+
+## Other features
+
+Micromatch also supports the following.
+
+### Extended globbing
+
+#### extglobs
+
+Extended globbing, as described by the bash man page:
+
+| **pattern** | **regex equivalent** | **description** | 
+| --- | --- | --- |
+| `?(pattern-list)` | `(... | ...)?` | Matches zero or one occurrence of the given patterns |
+| `*(pattern-list)` | `(... | ...)*` | Matches zero or more occurrences of the given patterns |
+| `+(pattern-list)` | `(... | ...)+` | Matches one or more occurrences of the given patterns |
+| `@(pattern-list)` | `(... | ...)` <sup>*</sup> | Matches one of the given patterns |
+| `!(pattern-list)` | N/A | Matches anything except one of the given patterns |
+
+<sup><strong>*</strong></sup> `@` isn't a RegEx character.
+
+Powered by [extglob](https://github.com/jonschlinkert/extglob). Visit that library for the full range of options or to report extglob related issues.
+
+See [extglob](https://github.com/jonschlinkert/extglob) for more information about extended globs.
+
+#### brace expansion
+
+In simple cases, brace expansion appears to work the same way as the logical `OR` operator. For example, `(a|b)` will achieve the same result as `{a,b}`.
+
+Here are some powerful features unique to brace expansion (versus character classes):
+
+* range expansion: `a{1..3}b/*.js` expands to: `['a1b/*.js', 'a2b/*.js', 'a3b/*.js']`
+* nesting: `a{c,{d,e}}b/*.js` expands to: `['acb/*.js', 'adb/*.js', 'aeb/*.js']`
+
+Visit [braces](https://github.com/jonschlinkert/braces) to ask questions and create an issue related to brace-expansion, or to see the full range of features and options related to brace expansion.
+
+#### regex character classes
+
+With the exception of brace expansion (`{a,b}`, `{1..5}`, etc), most of the special characters convert directly to regex, so you can expect them to follow the same rules and produce the same results as regex.
+
+For example, given the list: `['a.js', 'b.js', 'c.js', 'd.js', 'E.js']`:
+
+* `[ac].js`: matches both `a` and `c`, returning `['a.js', 'c.js']`
+* `[b-d].js`: matches from `b` to `d`, returning `['b.js', 'c.js', 'd.js']`
+* `[b-d].js`: matches from `b` to `d`, returning `['b.js', 'c.js', 'd.js']`
+* `a/[A-Z].js`: matches and uppercase letter, returning `['a/E.md']`
+
+Learn about [regex character classes](http://www.regular-expressions.info/charclass.html).
+
+#### regex groups
+
+Given `['a.js', 'b.js', 'c.js', 'd.js', 'E.js']`:
+
+* `(a|c).js`: would match either `a` or `c`, returning `['a.js', 'c.js']`
+* `(b|d).js`: would match either `b` or `d`, returning `['b.js', 'd.js']`
+* `(b|[A-Z]).js`: would match either `b` or an uppercase letter, returning `['b.js', 'E.js']`
+
+As with regex, parenthese can be nested, so patterns like `((a|b)|c)/b` will work. But it might be easier to achieve your goal using brace expansion.
+
+#### POSIX bracket expressions
+
+**Example**
+
+```js
+mm.isMatch('a1', '[[:alpha:][:digit:]]');
+//=> true
+```
+
+See [expand-brackets](https://github.com/jonschlinkert/expand-brackets) for more information about extended bracket expressions.
+
+***
+
+## Notes
+
+Whenever possible parsing behavior for patterns is based on globbing specifications in Bash 4.3. Patterns that aren't described by Bash follow wildmatch spec (used by git).

+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instantiating the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a string or array of strings to always treat as booleans
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values

+
+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable

+
+forIn(obj, function (value, key, o) {
+  keys.push(key);
+  values.push(value);
+});
+
+console.log(keys);
+//=> ['a', 'b', 'c'];
+
+console.log(values);
+//=> ['foo', 'bar', 'baz'];

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
+
+# install
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install mkdirp
+```
+
+to get the library, or
+
+```
+npm install -g mkdirp
+```
+
+to get the command.

+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# mute-stream
+
+Bytes go in, but they don't come out (when muted).
+
+This is a basic pass-through stream, but when muted, the bytes are
+silently dropped, rather than being passed through.
+
+## Usage
+
+```javascript
+var MuteStream = require('mute-stream')
+
+var ms = new MuteStream(options)
+
+ms.pipe(process.stdout)
+ms.write('foo') // writes 'foo' to stdout
+ms.mute()
+ms.write('bar') // does not write 'bar'
+ms.unmute()
+ms.write('baz') // writes 'baz' to stdout
+
+// can also be used to mute incoming data
+var ms = new MuteStream
+input.pipe(ms)
+
+ms.on('data', function (c) {
+  console.log('data: ' + c)
+})
+
+input.emit('data', 'foo') // logs 'foo'
+ms.mute()
+input.emit('data', 'bar') // does not log 'bar'
+ms.unmute()
+input.emit('data', 'baz') // logs 'baz'
+```
+
+## Options
+
+All options are optional.
+
+* `replace` Set to a string to replace each character with the
+  specified string when muted.  (So you can show `****` instead of the
+  password, for example.)
+
+* `prompt` If you are using a replacement char, and also using a
+  prompt with a readline stream (as for a `Password: *****` input),
+  then specify what the prompt is so that backspace will work
+  properly.  Otherwise, pressing backspace will overwrite the prompt
+  with the replacement character, which is weird.
+
+## ms.mute()
+
+Set `muted` to `true`.  Turns `.write()` into a no-op.
+
+## ms.unmute()
+
+Set `muted` to `false`
+
+## ms.isTTY
+
+True if the pipe destination is a TTY, or if the incoming pipe source is
+a TTY.
+
+## Other stream methods...
+
+The other standard readable and writable stream methods are all
+available.  The MuteStream object acts as a facade to its pipe source
+and destination.

+# next-tick
+## Environment agnostic nextTick polyfill
+
+To be used in environment agnostic modules that need nextTick functionality.
+
+- When run in Node.js `process.nextTick` is used
+- In modern browsers microtask resolution is guaranteed by `MutationObserver`
+- In other engines `setImmediate` or `setTimeout(fn, 0)` is used as fallback.
+- If none of the above is supported module resolves to `null`
+
+## Installation
+### NPM
+
+In your project path:
+
+	$ npm install next-tick
+
+#### Browser
+
+You can easily bundle `next-tick` for browser with any CJS bundler, e.g. [modules-webmake](https://github.com/medikoo/modules-webmake)
+
+## Tests [![Build Status](https://api.travis-ci.org/medikoo/next-tick.png?branch=master)](https://travis-ci.org/medikoo/next-tick)
+
+	$ npm test

+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]

+
+Transform a string to lower space cased. Optional locale and replacement character supported.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install no-case --save
+```
+
+## Usage
+
+```javascript
+var noCase = require('no-case')
+
+noCase(null)              //=> ""
+noCase('string')          //=> "string"
+noCase('dot.case')        //=> "dot case"
+noCase('camelCase')       //=> "camel case"
+noCase('Beyoncé Knowles') //=> "beyoncé knowles"
+
+noCase('A STRING', 'tr') //=> "a strıng"
+
+noCase('HELLO WORLD!', null, '_') //=> "hello_world"

+node
+========
+
+Installs a `node` binary into your project, which because `npm` runs scripts with the local `./node_modules/.bin` in the `PATH` ahead of the system copy means you can have a local version of node that is different than your system's, and manage node as a normal dependency.
+
+Warning: don't install this globally with npm 2. `npm@2` immediately removes node, then can't run the scripts that make this work.
+
+Use
+---
+
+```
+npm i node@lts
+```
+
+Use with `npx`
+--------------
+
+```
+npx node@4 myscript.js
+```
+
+This will run `myscript.js` with the latest version of node from the v4 major.
+
+Using the shell auto-fallback of npx, you can even do it like so:
+
+
+```
+node@4 myscript.js
+```
+
+Thanks
+------
+
+Major thanks to Kat Marchán for late-night problem solving, and to CJ Silverio and Maciej Małecki for egging me on way back when I had the idea to package node up this way. It does turn out if you ask "why _not_?!" once in a while something fun happens.

+     #  A large portion of the dictionary entries

+     #  Free Software applies to the current dictionary as well.
+     #
+     #  Each User may also freely distribute the Program, whether in its

+     #  that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear

+     #
+     #  NO WARRANTY
+     #
+     #  The program was produced on an experimental basis in the course of the

+     #  to users as so produced on an experimental basis.  Accordingly, the

+     #  performance, merchantability and fitness for a particular purpose of
+     #  the program and the nonexistence of any infringement or violation of
+     #  any right of any third party.
+     #
+     #  Each user of the program will agree and understand, and be deemed to
+     #  have agreed and understood, that there is no warranty whatsoever for
+     #  the program and, accordingly, the entire risk arising from or
+     #  otherwise connected with the program is assumed by the user.
+     #
+     #  Therefore, neither ICOT, the copyright holder, or any other
+     #  organization that participated in or was otherwise related to the
+     #  development of the program and their respective officials, directors,
+     #  officers and other employees shall be held liable for any and all

+     #  with the use or inability to use the program or any product, material
+     #  or result produced or otherwise obtained by using the program,
+     #  regardless of whether they have been advised of, or otherwise had
+     #  knowledge of, the possibility of such damages at any time during the
+     #  project or thereafter.  Each user will be deemed to have agreed to the
+     #  foregoing by his or her commencement of use of the program.  The term
+     #  "use" as used herein includes, but is not limited to, the use,
+     #  modification, copying and distribution of the program and the
+     #  production of secondary products from the program.
+     #
+     #  In the case where the program, whether in its original form or

+     #  any person, organization or entity other than ICOT, unless it makes or
+     #  grants independently of ICOT any specific warranty to the user in
+     #  writing, such person, organization or entity, will also be exempted

+    5. Time Zone Database
+
+      ICU uses the public domain data and code derived from Time Zone
+    Database for its time zone support. The ownership of the TZ database
+    is explained in BCP 175: Procedure for Maintaining the Time Zone
+    Database section 7.
+
+     # 7.  Database Ownership
+     #
+     #    The TZ database itself is not an IETF Contribution or an IETF
+     #    document.  Rather it is a pre-existing and regularly updated work
+     #    that is in the public domain, and is intended to remain in the
+     #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
+     #    not apply to the TZ Database or contributions that individuals make
+     #    to it.  Should any claims be made and substantiated against the TZ
+     #    Database, the organization that is providing the IANA
+     #    Considerations defined in this RFC, under the memorandum of
+     #    understanding with the IETF, currently ICANN, may act in accordance
+     #    with all competent court orders.  No ownership claims will be made
+     #    by ICANN or the IETF Trust on the database or the code.  Any person
+     #    making a contribution to the database or code waives all rights to
+     #    future claims in that contribution or in the TZ Database.

+

+
+    Copyright (c) 2000-2006, The Perl Foundation.
+
+    Everyone is permitted to copy and distribute verbatim copies
+    of this license document, but changing it is not allowed.
+
+    Preamble
+
+    This license establishes the terms under which a given free software
+    Package may be copied, modified, distributed, and/or redistributed.
+    The intent is that the Copyright Holder maintains some artistic
+    control over the development of that Package while still keeping the
+    Package available as open source and free software.
+
+    You are always permitted to make arrangements wholly outside of this
+    license directly with the Copyright Holder of a given Package.  If the
+    terms of this license do not permit the full use that you propose to
+    make of the Package, you should contact the Copyright Holder and seek
+    a different licensing arrangement.
+
+    Definitions
+
+        "Copyright Holder" means the individual(s) or organization(s)
+        named in the copyright notice for the entire Package.
+
+        "Contributor" means any party that has contributed code or other
+        material to the Package, in accordance with the Copyright Holder's
+        procedures.
+
+        "You" and "your" means any person who would like to copy,
+        distribute, or modify the Package.
+
+        "Package" means the collection of files distributed by the
+        Copyright Holder, and derivatives of that collection and/or of
+        those files. A given Package may consist of either the Standard
+        Version, or a Modified Version.
+
+        "Distribute" means providing a copy of the Package or making it
+        accessible to anyone else, or in the case of a company or
+        organization, to others outside of your company or organization.
+
+        "Distributor Fee" means any fee that you charge for Distributing
+        this Package or providing support for this Package to another
+        party.  It does not mean licensing fees.
+
+        "Standard Version" refers to the Package if it has not been
+        modified, or has been modified only in ways explicitly requested
+        by the Copyright Holder.
+
+        "Modified Version" means the Package, if it has been changed, and
+        such changes were not explicitly requested by the Copyright
+        Holder.
+
+        "Original License" means this Artistic License as Distributed with
+        the Standard Version of the Package, in its current version or as
+        it may be modified by The Perl Foundation in the future.
+
+        "Source" form means the source code, documentation source, and
+        configuration files for the Package.
+
+        "Compiled" form means the compiled bytecode, object code, binary,
+        or any other form resulting from mechanical transformation or
+        translation of the Source form.
+
+    Permission for Use and Modification Without Distribution
+
+    (1)  You are permitted to use the Standard Version and create and use
+    Modified Versions for any purpose without restriction, provided that
+    you do not Distribute the Modified Version.
+
+    Permissions for Redistribution of the Standard Version
+
+    (2)  You may Distribute verbatim copies of the Source form of the
+    Standard Version of this Package in any medium without restriction,
+    either gratis or for a Distributor Fee, provided that you duplicate
+    all of the original copyright notices and associated disclaimers.  At
+    your discretion, such verbatim copies may or may not include a
+    Compiled form of the Package.
+
+    (3)  You may apply any bug fixes, portability changes, and other
+    modifications made available from the Copyright Holder.  The resulting
+    Package will still be considered the Standard Version, and as such
+    will be subject to the Original License.
+
+    Distribution of Modified Versions of the Package as Source
+
+    (4)  You may Distribute your Modified Version as Source (either gratis
+    or for a Distributor Fee, and with or without a Compiled form of the
+    Modified Version) provided that you clearly document how it differs
+    from the Standard Version, including, but not limited to, documenting
+    any non-standard features, executables, or modules, and provided that
+    you do at least ONE of the following:
+
+        (a)  make the Modified Version available to the Copyright Holder
+        of the Standard Version, under the Original License, so that the
+        Copyright Holder may include your modifications in the Standard
+        Version.
+
+        (b)  ensure that installation of your Modified Version does not
+        prevent the user installing or running the Standard Version. In
+        addition, the Modified Version must bear a name that is different
+        from the name of the Standard Version.
+
+        (c)  allow anyone who receives a copy of the Modified Version to
+        make the Source form of the Modified Version available to others
+        under
+
+            (i)  the Original License or
+
+            (ii)  a license that permits the licensee to freely copy,
+            modify and redistribute the Modified Version using the same
+            licensing terms that apply to the copy that the licensee
+            received, and requires that the Source form of the Modified
+            Version, and of any works derived from it, be made freely
+            available in that license fees are prohibited but Distributor
+            Fees are allowed.
+
+    Distribution of Compiled Forms of the Standard Version
+    or Modified Versions without the Source
+
+    (5)  You may Distribute Compiled forms of the Standard Version without
+    the Source, provided that you include complete instructions on how to
+    get the Source of the Standard Version.  Such instructions must be
+    valid at the time of your distribution.  If these instructions, at any
+    time while you are carrying out such distribution, become invalid, you
+    must provide new instructions on demand or cease further distribution.
+    If you provide valid instructions or cease distribution within thirty
+    days after you become aware that the instructions are invalid, then
+    you do not forfeit any of your rights under this license.
+
+    (6)  You may Distribute a Modified Version in Compiled form without
+    the Source, provided that you comply with Section 4 with respect to
+    the Source of the Modified Version.
+
+    Aggregating or Linking the Package
+
+    (7)  You may aggregate the Package (either the Standard Version or
+    Modified Version) with other packages and Distribute the resulting
+    aggregation provided that you do not charge a licensing fee for the
+    Package.  Distributor Fees are permitted, and licensing fees for other
+    components in the aggregation are permitted. The terms of this license
+    apply to the use and Distribution of the Standard or Modified Versions
+    as included in the aggregation.
+
+    (8) You are permitted to link Modified and Standard Versions with
+    other works, to embed the Package in a larger work of your own, or to
+    build stand-alone binary or bytecode versions of applications that
+    include the Package, and Distribute the result without restriction,
+    provided the result does not expose a direct interface to the Package.
+
+    Items That are Not Considered Part of a Modified Version
+
+    (9) Works (including, but not limited to, modules and scripts) that
+    merely extend or make use of the Package, do not, by themselves, cause
+    the Package to be a Modified Version.  In addition, such works are not
+    considered parts of the Package itself, and are not subject to the
+    terms of this license.
+
+    General Provisions
+
+    (10)  Any use, modification, and distribution of the Standard or
+    Modified Versions is governed by this Artistic License. By using,
+    modifying or distributing the Package, you accept this license. Do not
+    use, modify, or distribute the Package, if you do not accept this
+    license.
+
+    (11)  If your Modified Version has been derived from a Modified
+    Version made by someone other than you, you are nevertheless required
+    to ensure that your Modified Version complies with the requirements of
+    this license.
+
+    (12)  This license does not grant you the right to use any trademark,
+    service mark, tradename, or logo of the Copyright Holder.
+
+    (13)  This license includes the non-exclusive, worldwide,
+    free-of-charge patent license to make, have made, use, offer to sell,
+    sell, import and otherwise transfer the Package with respect to any
+    patent claims licensable by the Copyright Holder that are necessarily
+    infringed by the Package. If you institute patent litigation
+    (including a cross-claim or counterclaim) against any party alleging
+    that the Package constitutes direct or contributory patent
+    infringement, then this Artistic License to you shall terminate on the
+    date that such litigation is filed.
+
+    (14)  Disclaimer of Warranty:
+    THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
+    IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
+    NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
+    LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
+    BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+    DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
+    ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

+## Support
+
+Looking for help? Check out the
+[instructions for getting support](.github/SUPPORT.md).
+
+## Release Types
+
+* **Current**: Under active development. Code for the Current release is in the
+  branch for its major version number (for example,
+  [v10.x](https://github.com/nodejs/node/tree/v10.x)). Node.js releases a new
+  major version every 6 months, allowing for breaking changes. This happens in
+  April and October every year. Releases appearing each October have a support
+  life of 8 months. Releases appearing each April convert to LTS (see below)
+  each October.
+* **LTS**: Releases that receive Long-term Support, with a focus on stability
+  and security. Every even-numbered major version will become an LTS release.
+  LTS releases receive 12 months of _Active LTS_ support and a further 18 months
+  of _Maintenance_. LTS release lines have alphabetically-ordered codenames,
+  beginning with v4 Argon. There are no breaking changes or feature additions,
+  except in some special circumstances.
+* **Nightly**: Code from the Current branch built every 24-hours when there are
+  changes. Use with caution.
+
+Current and LTS releases follow [Semantic Versioning](https://semver.org). A
+member of the Release Team [signs](#release-keys) each Current and LTS release.
+For more information, see the
+[Release README](https://github.com/nodejs/Release#readme).
+
+### Download
+
+Binaries, installers, and source tarballs are available at
+<https://nodejs.org/en/download/>.
+
+#### Current and LTS Releases
+<https://nodejs.org/download/release/>
+
+The [latest](https://nodejs.org/download/release/latest/) directory is an
+alias for the latest Current release. The latest-_codename_ directory is an
+alias for the latest release from an LTS line. For example, the
+[latest-carbon](https://nodejs.org/download/release/latest-carbon/) directory
+contains the latest Carbon (Node.js 8) release.
+
+#### Nightly Releases
+<https://nodejs.org/download/nightly/>
+
+Each directory name and filename contains a date (in UTC time) and the commit
+SHA at the HEAD of the release.
+
+#### API Documentation
+
+Documentation for the latest Current release is at <https://nodejs.org/api/>.
+Version-specific documentation is available in each release directory in the
+_docs_ subdirectory. Version-specific documentation is also at
+<https://nodejs.org/download/docs/>.
+
+### Verifying Binaries
+
+Download directories contain a `SHASUMS256.txt` file with SHA checksums for the
+files.
+
+To download `SHASUMS256.txt` using `curl`:
+
+```console
+$ curl -O https://nodejs.org/dist/vx.y.z/SHASUMS256.txt
+```
+
+To check that a downloaded file matches the checksum, run
+it through `sha256sum` with a command such as:
+
+```console
+$ grep node-vx.y.z.tar.gz SHASUMS256.txt | sha256sum -c -
+```
+
+For Current and LTS, the GPG detached signature of `SHASUMS256.txt` is in
+`SHASUMS256.txt.sig`. You can use it with `gpg` to verify the integrity of
+`SHASUM256.txt`. You will first need to import
+[the GPG keys of individuals authorized to create releases](#release-keys). To
+import the keys:
+
+```console
+$ gpg --keyserver pool.sks-keyservers.net --recv-keys DD8F2338BAE7501E3DD5AC78C273792F7D83545D
+```
+
+See the bottom of this README for a full script to import active release keys.
+
+Next, download the `SHASUMS256.txt.sig` for the release:
+
+```console
+$ curl -O https://nodejs.org/dist/vx.y.z/SHASUMS256.txt.sig
+```
+
+Then use `gpg --verify SHASUMS256.txt.sig SHASUMS256.txt` to verify
+the file's signature.

+ * Unsolved problem: if a type is actually a pointer type, like
+ * nid_triple is, then its impossible to get a const where you need
+ * it. Consider:
+ *
+ * typedef int nid_triple[3];
+ * const void *a_;
+ * const nid_triple const *a = a_;
+ *
+ * The assignment discards a const because what you really want is:
+ *
+ * const int const * const *a = a_;
+ *
+ * But if you do that, you lose the fact that a is an array of 3 ints,
+ * which breaks comparison functions.
+ *
+ * Thus we end up having to cast, sadly, or unpack the
+ * declarations. Or, as I finally did in this case, declare nid_triple
+ * to be a struct, which it should have been in the first place.
+ *
+ * Ben, August 2008.
+ *
+ * Also, strictly speaking not all types need be const, but handling
+ * the non-constness means a lot of complication, and in practice
+ * comparison routines do always not touch their arguments.

+  In OpenSSL, opensslconf.h was generated by Configure script with
+  specifying a target argument, where it includes several defines that
+  depend on OS and architecture platform.
+
+  In node, we statically mapped --dest-os and --dest-cpu options in
+  configure to the target of Configure in OpenSSL and make
+  `deps/openssl/conf/openssconf.h` so as to include each file
+  according to its target by checking pre-defined compiler macros.
+
+  Included opnesslconf.h files for supported target architectures can
+  be generated by `Makefile` and stored under
+  `archs/{target}/asm/opensslconf.h`. The Makefile also fixes several
+  defines to meet node build requirements.
+
+  Here is a map table of configure options in node, target arch of
+  Configure in OpenSSL and CI support.

+ * 0.9.3-beta2-dev 0x00903002

+ * The macros below are to be used for shared library (.so, .dll, ...)
+ * versioning.  That kind of versioning works a bit differently between
+ * operating systems.  The most usual scheme is to set a major and a minor
+ * number, and have the runtime loader check that the major number is equal
+ * to what it was at application link time, while the minor number has to
+ * be greater or equal to what it was at application link time.  With this
+ * scheme, the version number is usually part of the file name, like this:
+ *
+ *      libcrypto.so.0.9
+ *
+ * Some unixen also make a softlink with the major version number only:
+ *
+ *      libcrypto.so.0
+ *
+ * On Tru64 and IRIX 6.x it works a little bit differently.  There, the
+ * shared library version is stored in the file, and is actually a series
+ * of versions, separated by colons.  The rightmost version present in the
+ * library when linking an application is stored in the application to be
+ * matched at run time.  When the application is run, a check is done to
+ * see if the library version stored in the application matches any of the
+ * versions in the version string of the library itself.
+ * This version string can be constructed in any way, depending on what
+ * kind of matching is desired.  However, to implement the same scheme as
+ * the one used in the other unixen, all compatible versions, from lowest
+ * to highest, should be part of the string.  Consecutive builds would
+ * give the following versions strings:
+ *
+ *      3.0
+ *      3.0:3.1
+ *      3.0:3.1:3.2
+ *      4.0
+ *      4.0:4.1
+ *
+ * Notice how version 4 is completely incompatible with version, and
+ * therefore give the breach you can see.
+ *
+ * There may be other schemes as well that I haven't yet discovered.
+ *
+ * So, here's the way it works here: first of all, the library version
+ * number doesn't need at all to match the overall OpenSSL version.
+ * However, it's nice and more understandable if it actually does.
+ * The current library version is stored in the macro SHLIB_VERSION_NUMBER,
+ * which is just a piece of text in the format "M.m.e" (Major, minor, edit).
+ * For the sake of Tru64, IRIX, and any other OS that behaves in similar ways,
+ * we need to keep a history of version numbers, which is done in the
+ * macro SHLIB_VERSION_HISTORY.  The numbers are separated by colons and
+ * should only keep the versions that are binary compatible with the current.

+   The following functions are used to add strings to be printed and prompt
+   strings to prompt for data.  The names are UI_{add,dup}_<function>_string
+   and UI_{add,dup}_input_boolean.
+
+   UI_{add,dup}_<function>_string have the following meanings:
+        add     add a text or prompt string.  The pointers given to these
+                functions are used verbatim, no copying is done.
+        dup     make a copy of the text or prompt string, then add the copy
+                to the collection of strings in the user interface.
+        <function>
+                The function is a name for the functionality that the given
+                string shall be used for.  It can be one of:
+                        input   use the string as data prompt.
+                        verify  use the string as verification prompt.  This
+                                is used to verify a previous input.
+                        info    use the string for informational output.
+                        error   use the string for error output.
+   Honestly, there's currently no difference between info and error for the
+   moment.
+
+   UI_{add,dup}_input_boolean have the same semantics for "add" and "dup",
+   and are typically used when one wants to prompt for a yes/no response.
+
+   All of the functions in this group take a UI and a prompt string.
+   The string input and verify addition functions also take a flag argument,
+   a buffer for the result to end up with, a minimum input size and a maximum
+   input size (the result buffer MUST be large enough to be able to contain
+   the maximum number of characters).  Additionally, the verify addition
+   functions takes another buffer to compare the result against.
+   The boolean input functions take an action description string (which should
+   be safe to ignore if the expected user action is obvious, for example with
+   a dialog box with an OK button and a Cancel button), a string of acceptable
+   characters to mean OK and to mean Cancel.  The two last strings are checked
+   to make sure they don't have common characters.  Additionally, the same
+   flag argument as for the string input is taken, as well as a result buffer.
+   The result buffer is required to be at least one byte long.  Depending on
+   the answer, the first character from the OK or the Cancel character strings
+   will be stored in the first byte of the result buffer.  No NUL will be
+   added, so the result is *not* a string.
+
+   On success, the all return an index of the added information.  That index
+   is useful when retrieving results with UI_get0_result(). */

+   A method contains a number of functions that implement the low level
+   of the User Interface.  The functions are:
+
+        an opener       This function starts a session, maybe by opening
+                        a channel to a tty, or by opening a window.
+        a writer        This function is called to write a given string,
+                        maybe to the tty, maybe as a field label in a
+                        window.
+        a flusher       This function is called to flush everything that
+                        has been output so far.  It can be used to actually
+                        display a dialog box after it has been built.
+        a reader        This function is called to read a given prompt,
+                        maybe from the tty, maybe from a field in a
+                        window.  Note that it's called with all string
+                        structures, not only the prompt ones, so it must
+                        check such things itself.
+        a closer        This function closes the session, maybe by closing
+                        the channel to the tty, or closing the window.
+
+   All these functions are expected to return:
+
+        0       on error.
+        1       on success.
+        -1      on out-of-band events, for example if some prompting has
+                been canceled (by pressing Ctrl-C, for example).  This is
+                only checked when returned by the flusher or the reader.
+
+   The way this is used, the opener is first called, then the writer for all
+   strings, then the flusher, then the reader for all strings and finally the
+   closer.  Note that if you want to prompt from a terminal or other command
+   line interface, the best is to have the reader also write the prompts
+   instead of having the writer do it.  If you want to prompt from a dialog
+   box, the writer can be used to build up the contents of the box, and the
+   flusher to actually display the box and run the event loop until all data
+   has been given, after which the reader only grabs the given data and puts
+   them back into the UI strings.
+
+   All method functions take a UI as argument.  Additionally, the writer and
+   the reader take a UI_STRING.

+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *  - every search path from the root to a leaf consists of the
+ *    same number of black nodes,
+ *  - each red node (except for the root) has a black parent,
+ *  - each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).

+ * An object reference managed by the v8 garbage collector.
+ *
+ * All objects returned from v8 have to be tracked by the garbage
+ * collector so that it knows that the objects are still alive.  Also,
+ * because the garbage collector may move objects, it is unsafe to
+ * point directly to an object.  Instead, all objects are stored in
+ * handles which are known by the garbage collector and updated
+ * whenever an object moves.  Handles should always be passed by value
+ * (except in cases like out-parameters) and they should never be
+ * allocated on the heap.
+ *
+ * There are two types of handles: local and persistent handles.
+ *
+ * Local handles are light-weight and transient and typically used in
+ * local operations.  They are managed by HandleScopes. That means that a
+ * HandleScope must exist on the stack when they are created and that they are
+ * only valid inside of the HandleScope active during their creation.
+ * For passing a local handle to an outer HandleScope, an EscapableHandleScope
+ * and its Escape() method must be used.
+ *
+ * Persistent handles can be used when storing objects across several
+ * independent operations and have to be explicitly deallocated when they're no
+ * longer used.
+ *
+ * It is safe to extract the object stored in the handle by
+ * dereferencing the handle (for instance, to extract the Object* from
+ * a Local<Object>); the value will still be governed by a handle
+ * behind the scenes and the same rules apply to these values as to
+ * their handles.

+/**
+ * A FunctionTemplate is used to create functions at runtime. There
+ * can only be one function created from a FunctionTemplate in a
+ * context.  The lifetime of the created function is equal to the
+ * lifetime of the context.  So in case the embedder needs to create
+ * temporary functions that can be collected using Scripts is
+ * preferred.
+ *
+ * Any modification of a FunctionTemplate after first instantiation will trigger
+ * a crash.
+ *
+ * A FunctionTemplate can have properties, these properties are added to the
+ * function object when it is created.
+ *
+ * A FunctionTemplate has a corresponding instance template which is
+ * used to create object instances when the function is used as a
+ * constructor. Properties added to the instance template are added to
+ * each object instance.
+ *
+ * A FunctionTemplate can have a prototype template. The prototype template
+ * is used to create the prototype object of the function.
+ *
+ * The following example shows how to use a FunctionTemplate:
+ *
+ * \code
+ *    v8::Local<v8::FunctionTemplate> t = v8::FunctionTemplate::New(isolate);
+ *    t->Set(isolate, "func_property", v8::Number::New(isolate, 1));
+ *
+ *    v8::Local<v8::Template> proto_t = t->PrototypeTemplate();
+ *    proto_t->Set(isolate,
+ *                 "proto_method",
+ *                 v8::FunctionTemplate::New(isolate, InvokeCallback));
+ *    proto_t->Set(isolate, "proto_const", v8::Number::New(isolate, 2));
+ *
+ *    v8::Local<v8::ObjectTemplate> instance_t = t->InstanceTemplate();
+ *    instance_t->SetAccessor(String::NewFromUtf8(isolate, "instance_accessor"),
+ *                            InstanceAccessorCallback);
+ *    instance_t->SetHandler(
+ *        NamedPropertyHandlerConfiguration(PropertyHandlerCallback));
+ *    instance_t->Set(String::NewFromUtf8(isolate, "instance_property"),
+ *                    Number::New(isolate, 3));
+ *
+ *    v8::Local<v8::Function> function = t->GetFunction();
+ *    v8::Local<v8::Object> instance = function->NewInstance();
+ * \endcode
+ *
+ * Let's use "function" as the JS variable name of the function object
+ * and "instance" for the instance object created above.  The function
+ * and the instance will have the following properties:
+ *
+ * \code
+ *   func_property in function == true;
+ *   function.func_property == 1;
+ *
+ *   function.prototype.proto_method() invokes 'InvokeCallback'
+ *   function.prototype.proto_const == 2;
+ *
+ *   instance instanceof function == true;
+ *   instance.instance_accessor calls 'InstanceAccessorCallback'
+ *   instance.instance_property == 3;
+ * \endcode
+ *
+ * A FunctionTemplate can inherit from another one by calling the
+ * FunctionTemplate::Inherit method.  The following graph illustrates
+ * the semantics of inheritance:
+ *
+ * \code
+ *   FunctionTemplate Parent  -> Parent() . prototype -> { }
+ *     ^                                                  ^
+ *     | Inherit(Parent)                                  | .__proto__
+ *     |                                                  |
+ *   FunctionTemplate Child   -> Child()  . prototype -> { }
+ * \endcode
+ *
+ * A FunctionTemplate 'Child' inherits from 'Parent', the prototype
+ * object of the Child() function has __proto__ pointing to the
+ * Parent() function's prototype object. An instance of the Child
+ * function has all properties on Parent's instance templates.
+ *
+ * Let Parent be the FunctionTemplate initialized in the previous
+ * section and create a Child FunctionTemplate by:
+ *
+ * \code
+ *   Local<FunctionTemplate> parent = t;
+ *   Local<FunctionTemplate> child = FunctionTemplate::New();
+ *   child->Inherit(parent);
+ *
+ *   Local<Function> child_function = child->GetFunction();
+ *   Local<Object> child_instance = child_function->NewInstance();
+ * \endcode
+ *
+ * The Child function and Child instance will have the following
+ * properties:
+ *
+ * \code
+ *   child_func.prototype.__proto__ == function.prototype;
+ *   child_instance.instance_accessor calls 'InstanceAccessorCallback'
+ *   child_instance.instance_property == 3;
+ * \endcode

+/**
+ * Multiple threads in V8 are allowed, but only one thread at a time is allowed
+ * to use any given V8 isolate, see the comments in the Isolate class. The
+ * definition of 'using a V8 isolate' includes accessing handles or holding onto
+ * object pointers obtained from V8 handles while in the particular V8 isolate.
+ * It is up to the user of V8 to ensure, perhaps with locking, that this
+ * constraint is not violated. In addition to any other synchronization
+ * mechanism that may be used, the v8::Locker and v8::Unlocker classes must be
+ * used to signal thread switches to V8.
+ *
+ * v8::Locker is a scoped lock object. While it's active, i.e. between its
+ * construction and destruction, the current thread is allowed to use the locked
+ * isolate. V8 guarantees that an isolate can be locked by at most one thread at
+ * any time. In other words, the scope of a v8::Locker is a critical section.
+ *
+ * Sample usage:
+* \code
+ * ...
+ * {
+ *   v8::Locker locker(isolate);
+ *   v8::Isolate::Scope isolate_scope(isolate);
+ *   ...
+ *   // Code using V8 and isolate goes here.
+ *   ...
+ * } // Destructor called here
+ * \endcode
+ *
+ * If you wish to stop using V8 in a thread A you can do this either by
+ * destroying the v8::Locker object as above or by constructing a v8::Unlocker
+ * object:
+ *
+ * \code
+ * {
+ *   isolate->Exit();
+ *   v8::Unlocker unlocker(isolate);
+ *   ...
+ *   // Code not using V8 goes here while V8 can run in another thread.
+ *   ...
+ * } // Destructor called here.
+ * isolate->Enter();
+ * \endcode
+ *
+ * The Unlocker object is intended for use in a long-running callback from V8,
+ * where you want to release the V8 lock for other threads to use.
+ *
+ * The v8::Locker is a recursive lock, i.e. you can lock more than once in a
+ * given thread. This can be useful if you have code that can be called either
+ * from code that holds the lock or from code that does not. The Unlocker is
+ * not recursive so you can not have several Unlockers on the stack at once, and
+ * you can not use an Unlocker in a thread that is not inside a Locker's scope.
+ *
+ * An unlocker will unlock several lockers if it has to and reinstate the
+ * correct depth of locking on its destruction, e.g.:
+ *
+ * \code
+ * // V8 not locked.
+ * {
+ *   v8::Locker locker(isolate);
+ *   Isolate::Scope isolate_scope(isolate);
+ *   // V8 locked.
+ *   {
+ *     v8::Locker another_locker(isolate);
+ *     // V8 still locked (2 levels).
+ *     {
+ *       isolate->Exit();
+ *       v8::Unlocker unlocker(isolate);
+ *       // V8 not locked.
+ *     }
+ *     isolate->Enter();
+ *     // V8 locked again (2 levels).
+ *   }

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip and raw deflate streams in
+  memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in the case of corrupted input.

+     The application must update next_in and avail_in when avail_in has dropped
+   to zero.  It must update next_out and avail_out when avail_out has dropped
+   to zero.  The application must initialize zalloc, zfree and opaque before
+   calling the init function.  All other fields are set by the compression
+   library and must not be updated by the application.
+
+     The opaque value provided by the application will be passed as the first
+   parameter for calls of zalloc and zfree.  This can be useful for custom
+   memory management.  The compression library attaches no meaning to the
+   opaque value.
+
+     zalloc must return Z_NULL if there is not enough memory for the object.
+   If zlib is used in a multi-threaded application, zalloc and zfree must be
+   thread safe.  In that case, zlib is thread-safe.  When zalloc and zfree are
+   Z_NULL on entry to the initialization function, they are set to internal
+   routines that use the standard library functions malloc() and free().
+
+     On 16-bit systems, the functions zalloc and zfree must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this if
+   the symbol MAXSEG_64K is defined (see zconf.h).  WARNING: On MSDOS, pointers
+   returned by zalloc for objects of exactly 65536 bytes *must* have their
+   offset normalized to zero.  The default allocation function provided by this
+   library ensures this (see zutil.c).  To reduce memory requirements and avoid
+   any allocation of 64K objects, at the expense of compression ratio, compile
+   the library with -DMAX_WBITS=14 (see zconf.h).
+
+     The fields total_in and total_out can be used for statistics or progress
+   reports.  After compression, total_in holds the total size of the
+   uncompressed data and may be saved for use by the decompressor (particularly
+   if the decompressor wants to decompress everything in a single step).

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary.  Some output may be provided even if
+    flush is zero.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending. See deflatePending(),
+  which can be used if desired to determine whether or not there is more ouput
+  in that case.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed
+  codes block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
+  function must be called again with Z_FINISH and more output space (updated
+  avail_out) but no more input data, until it returns with Z_STREAM_END or an
+  error.  After deflate has returned Z_STREAM_END, the only possible operations
+  on the stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used in the first deflate call after deflateInit if all the
+  compression is to be done in a single step.  In order to complete in one
+  call, avail_out must be at least the value returned by deflateBound (see
+  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
+  output space is provided, deflate will not return Z_STREAM_END, and it must
+  be called again as described above.
+
+    deflate() sets strm->adler to the Adler-32 checksum of all input read
+  so far (that is, total_in bytes).  If a gzip stream is being generated, then
+  strm->adler will be the CRC-32 checksum of the input read so far.  (See
+  deflateInit2 below.)
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  If in doubt, the data is
+  considered binary.  This field is only for information purposes and does not
+  affect the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL or the state was inadvertently written over
+  by the application), or Z_BUF_ERROR if no progress is possible (for example
+  avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not fatal, and

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), then next_in and avail_in are updated

+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  If the
+  caller of inflate() does not provide both available input and available
+  output space, it is possible that there will be no progress made.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  To assist in this, on return inflate() always sets strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.)  The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed Adler-32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained unless inflateGetHeader() is used.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
+  uncompressed length, modulo 2^32.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value, in which case strm->msg points to a string with a more specific
+  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL, or the state was inadvertently written over
+  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
+  if no progress was possible or if there was not enough room in the output
+  buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is to be attempted.

+
+     This is another version of deflateInit with more compression options.  The
+   fields next_in, zalloc, zfree and opaque must be initialized before by the
+   caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     For the current implementation of deflate(), a windowBits value of 8 (a
+   window size of 256 bytes) is not supported.  As a result, a request for 8
+   will result in 9 (a 512-byte window).  In that case, providing 8 to
+   inflateInit2() will result in an error when the zlib header with 9 is
+   checked against the initialization of inflate().  The remedy is to not use 8
+   with deflateInit2() with this initialization, or at least in that case use 9
+   with inflateInit2().
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute a check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to the appropriate value,
+   if the operating system was determined at compile time.  If a gzip stream is
+   being written, strm->adler is a CRC-32 instead of an Adler-32.
+
+     For raw deflate or gzip encoding, a request for a 256-byte window is
+   rejected as invalid, since only the zlib header provides a means of
+   transmitting the window size to the decompressor.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
+   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is

+
+     This is another version of inflateInit with an extra parameter.  The
+   fields next_in, avail_in, zalloc, zfree and opaque must be initialized
+   before by the caller.
+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library.  The default value is 15 if inflateInit is used
+   instead.  windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used.  If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be zero to request that inflate use the window size in
+   the zlib header of the compressed stream.
+
+     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
+   determines the window size.  inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream.  This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values.  If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is.  Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding.  Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will
+   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
+   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
+   below), inflate() will not automatically decode concatenated gzip streams.
+   inflate() will return Z_STREAM_END at the end of the gzip stream.  The state
+   would need to be reset to continue decoding a subsequent gzip stream.

+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the default
+   behavior of inflate(), which expects a zlib header and trailer around the
+   deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero -- buf is ignored in that
+   case -- and inflateBack() will return a buffer error.  inflateBack() will
+   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+   out() should return zero on success, or non-zero on failure.  If out()
+   returns non-zero, inflateBack() will return with an error.  Neither in() nor
+   out() are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.)  Note that inflateBack()
+   cannot return Z_OK.

+# noncharacters [![NPM version](https://badge.fury.io/js/noncharacters.svg)](http://badge.fury.io/js/noncharacters)
+
+> 34 non-character code points (labeled <not a character>), that are set aside and guaranteed to never be used for a character. Perfect to use for placeholders or temporary replacements during string transformations.
+
+See the wikipedia [article on non-characters][wiki]. Also, I used [regenerate](https://github.com/mathiasbynens/regenerate) from [mathiasbynens](https://github.com/mathiasbynens) to generate the range of characters. 
+
+## Install with [npm](npmjs.org)
+
+```bash
+npm i noncharacters --save
+```
+
+## Usage
+
+```js
+var noncharacters = require('noncharacters');
+//=> ['\uFFFF', '\uFFFE', ...]
+```
+
+**Example**
+
+Let's say you need to transform a string but you need to temporarily replace some characters that might cause issues. 
+
+Create your own placeholders:
+
+```js
+// arbitrary characters we want to replace, 
+// mapped to placeholder non-characters
+var placeholders = {
+  '{': noncharacters[0],
+  '}': noncharacters[1]
+};
+
+// the string with characters to replace
+var str = 'This is a template: {name}';
+
+// actually replace the characters
+Object.keys(placeholders).forEach(function(ch) {
+  str = str.replace(ch, placeholders[ch]);
+});
+//=> This is a template: \uFFFFname\uFFFE
+```
+Now you can do whatever you want to `str`. Then, to change back:
+
+```js
+Object.keys(placeholders).forEach(function(ch) {
+  str = str.replace(placeholders[ch], ch);
+});
+//=> This is a template: {name}
+```
+
+
+## Run tests
+
+Install dev dependencies:
+
+```bash
+npm i -d && npm test
+```

+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save normalize-pkg
+```
+
+## Install
+
+Install with [bower](http://bower.io/)
+
+```sh
+$ bower install normalize-pkg --save
+```
+
+## Usage
+
+```js
+var config = require('./')();
+var pkg = config.normalize(require('./package'));
+```
+
+## Features
+
+Normalizes most package.json fields, and:
+
+* converts `repository` objects to a string
+* stringifies `author` object
+* stringifies each "person" object in `maintainers`, `contributors` and `collaborators`
+* converts `licenses` arrays and objects to a `license` string
+* removes files that don't exist from `bin`, `main` and the `files` array
+* adds `cli.js` to `bin` if it exists
+* creates `keywords` array from `name` if not defined
+
+See the [schema](lib/schema.js), [normalizers](lib/normalizers), and [unit tests](test) for more examples.
+
+## Schema
+
+Values are normalized using a [schema](lib/schema.js) that is passed to [map-schema](https://github.com/jonschlinkert/map-schema).
+
+* only properties that have a corresponding field on the schema will be normalized.
+* any properties that do not have a corresponding field are returned unmodified.
+
+See the [.field docs](#field) to learn how to add or overwrite a field on the schema.
+
+## Defaults
+
+A `default` value may optionally be defined when a `.field` is registered. When `.normalize` is run and a property that is required or recommended by npm is missing, `normalize-pkg` attempts to create the field if valid data can be found in the repository.
+
+built-in fields have a default value:
+
+* `version`: `'0.1.0'`
+* `license`: `'MIT'`
+* `engines`: `{node: '>= 0.10.0'}`
+
+For example:
+
+* `name`: the [project-name](https://github.com/jonschlinkert/project-name) library is used to fill in the name
+* `bin`: if empty, populated with `cli.js` or `bin` if either exists on the file system
+
+**Example**
+
+The following:
+
+```js
+var config = require('./')();
+
+// no package.json is passed, just an empty object
+var pkg = config.normalize({});
+console.log(pkg);
+```
+
+**Results**
+
+Since an empty object was passed, `normalize-pkg` was smart enough to fill in missing fields looking for info in the project. In this case, specifically from parsing `.git` config and using any defaults defined on the schema.
+
+```js
+{ name: 'normalize-pkg',
+  version: '0.1.0',
+  homepage: 'https://github.com/jonschlinkert/normalize-pkg',
+  repository: 'jonschlinkert/normalize-pkg',
+  license: 'MIT',
+  files: [ 'index.js' ],
+  main: 'index.js',
+  engines: { node: '>= 0.10.0' } }
+```
+
+## API
+
+### [NormalizePkg](index.js#L26)
+
+Create an instance of `NormalizePkg` with the given `options`.
+
+**Example**
+
+```js
+var config = new NormalizePkg();
+var pkg = config.normalize({
+  author: {
+    name: 'Jon Schlinkert',
+    url: 'https://github.com/jonschlinkert'
+  }
+});
+console.log(pkg);
+//=> {author: 'Jon Schlinkert (https://github.com/jonschlinkert)'}
+```
+
+**Params**
+
+* `options` **{Object}**
+
+### [.field](index.js#L76)
+
+Add a field to the schema, or overwrite or extend an existing field. The last argument is an `options` object that supports the following properties:
+
+* `normalize` **{Function}**: function to be called on the value when the `.normalize` method is called
+* `default` **{any}**: default value to be used when the package.json property is undefined.
+* `required` **{Boolean}**: define `true` if the property is required
+
+**Example**
+
+```js
+var config = new NormalizePkg();
+
+config.field('foo', 'string', {
+  default: 'bar'
+});
+
+var pkg = config.normalize({});
+console.log(pkg);
+//=> {foo:  'bar'}
+```
+
+**Params**
+
+* `name` **{String}**: Field name (required)
+* `type` **{String|Array}**: One or more native javascript types allowed for the property value (required)
+* `options` **{Object}**
+* `returns` **{Object}**: Returns the instance
+
+### [.normalize](index.js#L102)
+
+Iterate over `pkg` properties and normalize values that have corresponding [fields](#field) registered on the schema.
+
+**Example**
+
+```js
+var config = new NormalizePkg();
+var pkg = config.normalize(require('./package.json'));
+```
+
+**Params**
+
+* `pkg` **{Object}**: The `package.json` object to normalize
+* `options` **{Object}**
+* `returns` **{Object}**: Returns a normalized package.json object.
+
+## Options
+
+### options.knownOnly
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Omit properties from package.json that do not have a field registered on the schema.
+
+```js
+var Config = require('normalize-pkg');
+var config = new Config({knownOnly: true});
+
+var pkg = config.normalize({name: 'my-project', foo: 'bar'});
+console.log(pkg);
+//=> {name: 'my-project'}
+```
+
+### options.pick
+
+**Type**: `array`
+
+**Default**: `undefined`
+
+Filter the resulting object to contain only the specified keys.
+
+### options.omit
+
+**Type**: `array`
+
+**Default**: `undefined`
+
+Remove the specified keys from the resulting object.
+
+### options.fields
+
+Pass a `fields` object on the options to customize any fields on the schema (also see [options.extend](#options-extend)):
+
+```js
+var pkg = config.normalize(require('./package'), {
+  extend: true,
+  fields: {
+    name: {
+      normalize: function() {
+        return 'bar'
+      }
+    }
+  }
+});
+
+console.log(pkg.name);
+//=> 'bar'
+```
+
+### options.extend
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Used with [options.field](#options-field), pass `true` if you want to extend a field that is already defined on the schema.
+
+```js
+var pkg = config.normalize(require('./package'), {
+  extend: true,
+  fields: {
+    name: {
+      normalize: function() {
+        return 'bar'
+      }
+    }
+  }
+});
+
+console.log(pkg.name);
+//=> 'bar'
+```

+```
+
+## Usage
+
+```js
+var unique = require('array-unique');
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c']
+
+/* The above modifies the input array. To prevent that at a slight performance cost: */
+var unique = require("array-unique").immutable;
+
+var arr = ['a', 'b', 'c', 'c'];
+console.log(unique(arr)) //=> ['a', 'b', 'c']
+console.log(arr)         //=> ['a', 'b', 'c', 'c']

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+
+Map over an array of values in parallel or series, passing each through the async iterator.
+Optionally, specify lifecycle extension points for before the iterator runs, after completion,
+or upon error.
+
+## Usage
+
+```js
+var nal = require('now-and-later');
+
+function iterator(value, cb){
+  cb(null, value * 2)
+}
+
+function create(value, key){
+  // return an object to be based to each lifecycle method
+  return { key: key, value: value };
+}
+
+function before(storage){
+  console.log('before iterator');
+  console.log('initial value: ', storage.value);
+}
+
+function after(result, storage){
+  console.log('after iterator');
+  console.log('initial value: ', storage.value);
+  console.log('result: ', result);
+}
+
+function error(err, storage){
+  console.log('afer error in iterator');
+  console.log('error: ', err);
+}
+
+/*
+  Calling mapSeries with an object can't guarantee order
+  It uses Object.keys to get an order
+  It is better to use an array if order must be guaranteed
+ */
+nal.mapSeries([1, 2, 3], iterator {
+  create: create,
+  before: before,
+  after: after,
+  error: error
+}, console.log);
+
+nal.map({

+  fn2: fn2
+}, {
+  create: create,
+  before: before,
+  after: after,

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
+
+
+## Use the built-in
+
+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
+support `Object.assign()` :tada:. If you target only those environments, then by all
+means, use `Object.assign()` instead of this package.
+
+
+## Install
+
+```
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+const objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Return a copy of an object excluding the given key, or array of keys. Also accepts an optional filter function as the last argument.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save object.omit
+```
+
+## Usage
+
+```js
+var omit = require('object.omit');
+```
+
+Pass a string `key` to omit:
+
+```js
+omit({a: 'a', b: 'b', c: 'c'}, 'a')
+//=> { b: 'b', c: 'c' }
+```
+
+Pass an array of `keys` to omit:
+
+```js
+omit({a: 'a', b: 'b', c: 'c'}, ['a', 'c'])
+//=> { b: 'b' }
+```
+
+Returns the object if no keys are passed:
+
+```js
+omit({a: 'a', b: 'b', c: 'c'})
+//=> {a: 'a', b: 'b', c: 'c'}
+```
+
+Returns an empty object if no value is passed.
+
+```js
+omit()
+//=> {}
+```
+
+### Filter function
+
+An optional filter function may be passed as the last argument, with or without keys passed on the arguments:
+
+**filter on keys**
+
+```js
+var res = omit({a: 'a', b: 'b', c: 'c'}, function (val, key) {
+  return key === 'a';
+});
+//=> {a: 'a'}
+```
+
+**filter on values**
+
+```js
+var fn = function() {};
+var obj = {a: 'a', b: 'b', c: fn};
+
+var res = omit(obj, ['a'], function (val, key) {
+  return typeof val !== 'function';
+});
+//=> {b: 'b'}
+```

+
+```sh
+$ npm install has-values --save
+```
+
+## Usage
+
+```js
+var hasValue = require('has-values');
+
+hasValue('a');
+//=> true
+
+hasValue('');
+//=> false
+
+hasValue(1);
+//=> true
+
+hasValue(0);
+//=> false
+
+hasValue(0, true); // treat zero as a value
+//=> true
+
+hasValue({a: 'a'}});
+//=> true
+
+hasValue({}});
+//=> false
+
+hasValue(['a']);
+//=> true
+
+hasValue([]);
+//=> false
+
+hasValue(function(foo) {}); // function length/arity
+//=> true
+
+hasValue(function() {});
+//=> false
+
+hasValue(true);
+hasValue(false);
+//=> true
+```
+
+## isEmpty
+
+To test for empty values, do:
+
+```js
+function isEmpty(o, isZero) {
+  return !hasValue(o, isZero);
+}
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+util.inherits(App, Options);
+
+App.prototype.init = function() {
+  this.option('cwd', process.cwd());
+  this.option('foo', 'bar');
+};
+
+App.prototype.a = function(value) {
+  this.enable(value);
+};
+
+App.prototype.b = function(value) {

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+# ordered-read-streams [![NPM version](https://badge.fury.io/js/ordered-read-streams.png)](http://badge.fury.io/js/ordered-read-streams) [![Build Status](https://travis-ci.org/armed/ordered-read-streams.png?branch=master)](https://travis-ci.org/armed/ordered-read-streams)
+
+Combines array of streams into one read stream in strict order.
+
+## Installation
+
+`npm install ordered-read-streams`
+
+## Overview
+
+`ordered-read-streams` handles all data/errors from input streams in parallel, but emits data/errors in strict order in which streams are passed to constructor. This is `objectMode = true` stream.
+
+## Example
+
+```js
+var through = require('through2');
+var Ordered = require('ordered-read-streams');
+
+var s1 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 200)
+});
+var s2 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 30)
+});
+var s3 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 100)
+});
+
+var streams = new Ordered([s1, s2, s3]);
+streams.on('data', function (data) {
+  console.log(data);
+})
+
+s1.write('stream 1');
+s1.end();
+
+s2.write('stream 2');
+s2.end();
+
+s3.write('stream 3');
+s3.end();
+```
+Ouput will be:
+
+```
+stream 1
+stream 2
+stream 3
+```

+
+Parse a string into an object with `name`, `email` and `url` properties following npm conventions. Useful for the `authors` property in package.json or for parsing an AUTHORS file into an array of authors objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install parse-author --save
+```
+
+## Usage
+
+```js
+var authors = require('parse-author');
+
+authors('Jon Schlinkert <jon.schlinkert@sellside.com> (https://github.com/jonschlinkert)');
+//=> {name: 'Jon Schlinkert', email: 'jon.schlinkert@sellside.com', url: 'https://github.com/jonschlinkert'}
+```
+
+Any of the properties can be used or missing:
+
+```js
+authors('')
+//=> {}
+
+authors('Jon Schlinkert (https://github.com/jonschlinkert)');
+//=> {name: 'Jon Schlinkert', url: 'https://github.com/jonschlinkert'}

+
+> Parse `.git/config` into a JavaScript object. sync or async.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save parse-git-config
+```
+
+## Usage
+
+```js
+var parse = require('parse-git-config');
+
+// sync
+var config = parse.sync();
+
+// or async
+parse(function (err, config) {
+  // do stuff with err/config
+});
+```
+
+**Custom path and/or cwd**
+
+```js
+parse.sync({cwd: 'foo', path: '.git/config'});
+
+// async
+parse({cwd: 'foo', path: '.git/config'}, function (err, config) {
+  // do stuff 
+});
+```
+
+**Example result**
+
+Config object will be something like:
+
+```js
+{ core:
+   { repositoryformatversion: '0',
+     filemode: true,
+     bare: false,
+     logallrefupdates: true,
+     ignorecase: true,
+     precomposeunicode: true },
+  'remote "origin"':
+   { url: 'https://github.com/jonschlinkert/parse-git-config.git',
+     fetch: '+refs/heads/*:refs/remotes/origin/*' },
+  'branch "master"': { remote: 'origin', merge: 'refs/heads/master', ... } }
+```
+
+## API
+
+### [parse](index.js#L33)
+
+Asynchronously parse a `.git/config` file. If only the callback is passed, the `.git/config` file relative to `process.cwd()` is used.
+
+**Example**
+
+```js
+parse(function(err, config) {
+  if (err) throw err;
+  // do stuff with config
+});
+```
+
+**Params**
+
+* `options` **{Object|String|Function}**: Options with `cwd` or `path`, the cwd to use, or the callback function.
+* `cb` **{Function}**: callback function if the first argument is options or cwd.
+* `returns` **{Object}**
+
+### [.sync](index.js#L71)
+
+Synchronously parse a `.git/config` file. If no arguments are passed, the `.git/config` file relative to `process.cwd()` is used.
+
+**Example**
+
+```js
+var config = parse.sync();
+```
+
+**Params**
+
+* `options` **{Object|String}**: Options with `cwd` or `path`, or the cwd to use.
+* `returns` **{Object}**
+
+### [.keys](index.js#L109)
+
+Returns an object with only the properties that had ini-style keys converted to objects (example below).
+
+**Example**
+
+```js
+var config = parse.sync();
+var obj = parse.keys(config);
+```
+
+**Params**
+
+* `config` **{Object}**: The parsed git config object.
+* `returns` **{Object}**
+
+### .keys examples
+
+Converts ini-style keys into objects:
+
+**Example 1**
+
+```js
+var parse = require('parse-git-config');
+var config = { 
+  'foo "bar"': { doStuff: true },
+  'foo "baz"': { doStuff: true } 
+};
+
+console.log(parse.keys(config));
+```
+
+Results in:
+
+```js
+{ 
+  foo: { 
+    bar: { doStuff: true }, 
+    baz: { doStuff: true } 
+  } 
+}
+```
+
+**Example 2**
+
+```js
+var parse = require('parse-git-config');
+var config = {
+  'remote "origin"': { 
+    url: 'https://github.com/jonschlinkert/normalize-pkg.git',
+    fetch: '+refs/heads/*:refs/remotes/origin/*' 
+  },
+  'branch "master"': { 
+    remote: 'origin', 
+    merge: 'refs/heads/master' 
+  },
+  'branch "dev"': { 
+    remote: 'origin', 
+    merge: 'refs/heads/dev', 
+    rebase: true 
+  }
+};
+
+console.log(parse.keys(config));
+```
+
+Results in:
+
+```js
+{
+  remote: {
+    origin: {
+      url: 'https://github.com/jonschlinkert/normalize-pkg.git',
+      fetch: '+refs/heads/*:refs/remotes/origin/*'
+    }
+  },
+  branch: {
+    master: {
+      remote: 'origin',
+      merge: 'refs/heads/master'
+    },
+    dev: {
+      remote: 'origin',
+      merge: 'refs/heads/dev',
+      rebase: true
+    }
+  }
+}
+```

+
+> Parse a github URL into an object.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install parse-github-url --save
+```
+
+**HEADS UP! Breaking changes in 0.3.0!!!**
+
+See the [release history](#history) for details.
+
+**Why another GitHub URL parser library?**
+
+Seems like every lib I've found does too much, like both stringifying and parsing, or converts the URL from one format to another, only returns certain segments of the URL except for what I need, yields inconsistent results or has poor coverage.
+
+## Usage
+
+```js
+var gh = require('parse-github-url');
+gh('https://github.com/jonschlinkert/micromatch');
+```
+
+Results in:
+
+```js
+{
+  "owner": "jonschlinkert",
+  "name": "micromatch",
+  "repo": "jonschlinkert/micromatch",
+  "branch": "master"
+}

+## History
+
+**v0.3.0**
+
+To be more consistent with node.js/package.json conventions, the following properties were renamed in `v0.3.0`:
+
+* `repo` is now `name` (project name)
+* `repopath` is now `repository` (project repository)
+* `user` is now `owner` (project owner or org)

+# parse-glob [![NPM version](https://badge.fury.io/js/parse-glob.svg)](http://badge.fury.io/js/parse-glob)  [![Build Status](https://travis-ci.org/jonschlinkert/parse-glob.svg)](https://travis-ci.org/jonschlinkert/parse-glob)
+
+> Parse a glob pattern into an object of tokens.
+
+**Changes from v1.0.0 to v3.0.4**
+
+* all path-related properties are now on the `path` object
+* all boolean properties are now on the `is` object
+* adds `base` property
+
+See the [properties](#properties) section for details.
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i parse-glob --save
+```
+
+* parses 1,000+ glob patterns in 29ms (2.3 GHz Intel Core i7)
+* Extensive [unit tests](./test.js) (more than 1,000 lines), covering wildcards, globstars, character classes, brace patterns, extglobs, dotfiles and other complex patterns.
+
+See the tests for [hundreds of examples](./test.js).
+
+## Usage
+
+```js
+var parseGlob = require('parse-glob');
+```
+
+**Example**
+
+```js
+parseGlob('a/b/c/**/*.{yml,json}');
+```
+
+**Returns:**
+
+```js
+{ orig: 'a/b/c/**/*.{yml,json}',
+  is:
+   { glob: true,
+     negated: false,
+     extglob: false,
+     braces: true,
+     brackets: false,
+     globstar: true,
+     dotfile: false,
+     dotdir: false },
+  glob: '**/*.{yml,json}',
+  base: 'a/b/c',
+  path:
+   { dirname: 'a/b/c/**/',
+     basename: '*.{yml,json}',
+     filename: '*',
+     extname: '.{yml,json}',
+     ext: '{yml,json}' } }
+```
+
+## Properties
+
+The object returned by parseGlob has the following properties:
+
+* `orig`: a copy of the original, unmodified glob pattern
+* `is`: an object with boolean information about the glob:
+  - `glob`: true if the pattern actually a glob pattern
+  - `negated`: true if it's a negation pattern (`!**/foo.js`)
+  - `extglob`: true if it has extglobs (`@(foo|bar)`)
+  - `braces`: true if it has braces (`{1..2}` or `.{txt,md}`)
+  - `brackets`: true if it has POSIX brackets (`[[:alpha:]]`)
+  - `globstar`: true if the pattern has a globstar (double star, `**`)
+  - `dotfile`: true if the pattern should match dotfiles
+  - `dotdir`: true if the pattern should match dot-directories (like `.git`)
+* `glob`: the glob pattern part of the string, if any
+* `base`: the non-glob part of the string, if any
+* `path`: file path segments
+  - `dirname`: directory
+  - `basename`: file name with extension
+  - `filename`: file name without extension
+  - `extname`: file extension with dot
+  - `ext`: file extension without dot

+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+> Front matter parsing middleware based on gray-matter.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save parser-front-matter
+```
+
+This is similar to a consolidate.js engine, but for parsing. Works with [assemble](https://github.com/assemble/assemble), [verb](https://github.com/verbose/verb), [generate](https://github.com/generate/generate), [update](https://github.com/update/update), express.js, parser-cache, or any application with similar conventions.
+
+## Usage
+
+```js
+var parser = require('parser-front-matter');
+```
+
+## API
+
+### [.parse](index.js#L36)
+
+Parse front matter from the given string or the `contents` in the given `file` and callback `next(err, file)`.
+
+If an object is passed, either `file.contents` or `file.content`
+may be used (for gulp and assemble compatibility).
+
+**Params**
+
+* `file` **{String|Object}**: The object or string to parse.
+* `options` **{Object|Function}**: or `next` callback function. Options are passed to [gray-matter](https://github.com/jonschlinkert/gray-matter).
+* `next` **{Function}**: callback function.
+
+**Example**
+
+```js
+// pass a string
+parser.parse('---\ntitle: foo\n---\nbar', function (err, file) {
+  //=> {content: 'bar', data: {title: 'foo'}}
+});
+
+// or an object
+var file = {contents: new Buffer('---\ntitle: foo\nbar')};
+parser.parse(file, function(err, res) {
+  //=> {content: 'bar', data: {title: 'foo'}}
+});
+```
+
+### [.parseSync](index.js#L72)
+
+Parse front matter from the given string or the `contents` in the given `file`. If an object is passed, either `file.contents` or `file.content` may be used (for gulp and assemble compatibility).
+
+**Params**
+
+* `file` **{String|Object}**: The object or string to parse.
+* `options` **{Object}**: passed to [gray-matter](https://github.com/jonschlinkert/gray-matter).
+
+**Example**
+
+```js
+// pass a string
+var res = parser.parseSync('---\ntitle: foo\n---\nbar');
+
+// or an object
+var file = {contents: new Buffer('---\ntitle: foo\nbar')};
+var res = parser.parseSync(file);
+//=> {content: 'bar', data: {title: 'foo'}}
+```
+
+## file object
+
+Returned `file` objects have the following properties (no other properties are modified on the given file):
+
+* `data`: data from parsed front matter
+* `content`: the content string, excluding front-matter (assemble compatibility)
+* `contents`: the content string as a buffer, excluding front-matter
+* `orig`: the original content string with front-matter included

+# path-dirname [![Build Status](https://travis-ci.org/es128/path-dirname.svg?branch=master)](https://travis-ci.org/es128/path-dirname)
+
+> Node.js [`path.dirname()`](https://nodejs.org/api/path.html#path_path_dirname_path) [ponyfill](https://ponyfill.com)
+
+This was needed in order to expose `path.posix.dirname()` on Node.js v0.10
+
+## Install
+
+```
+$ npm install --save path-dirname
+```
+
+
+## Usage
+
+```js
+const pathDirname = require('path-dirname');
+
+pathDirname('/home/foo');
+//=> '/home'
+pathDirname('C:\\Users\\foo');
+//=> 'C:\\Users'
+pathDirname('foo');
+//=> '.'
+pathDirname('foo/bar');
+//=> 'foo'
+
+//Using posix version for consistent output when dealing with glob escape chars
+pathDirname.win32('C:\\Users\\foo/\\*bar');
+//=> 'C:\\Users\\foo/'
+pathDirname.posix('C:\\Users\\foo/\\*bar');
+//=> 'C:\\Users\\foo'
+```
+
+
+## API
+
+See the [`path.dirname()` docs](https://nodejs.org/api/path.html#path_path_dirname_path).
+
+### pathDirname(path)
+
+### pathDirname.posix(path)
+
+POSIX specific version.
+
+### pathDirname.win32(path)
+
+Windows specific version.

+- **path** An Express-style string, an array of strings, or a regular expression.
+- **keys** An array to be populated with the keys found in the path.
+- **options**
+  - **sensitive** When `true` the route will be case sensitive. (default: `false`)
+  - **strict** When `false` the trailing slash is optional. (default: `false`)
+  - **end** When `false` the path will match at the beginning. (default: `true`)
+  - **delimiter** Set the default delimiter for repeat parameters. (default: `'/'`)
+
+```javascript
+var keys = []
+var re = pathToRegexp('/foo/:bar', keys)
+// re = /^\/foo\/([^\/]+?)\/?$/i
+// keys = [{ name: 'bar', prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '[^\\/]+?' }]
+```
+
+**Please note:** The `RegExp` returned by `path-to-regexp` is intended for use with pathnames or hostnames. It can not handle the query strings or fragments of a URL.
+
+### Parameters
+
+The path string can be used to define parameters and populate the keys.
+
+#### Named Parameters
+
+Named parameters are defined by prefixing a colon to the parameter name (`:foo`). By default, the parameter will match until the following path segment.
+
+```js
+var re = pathToRegexp('/:foo/:bar', keys)
+// keys = [{ name: 'foo', prefix: '/', ... }, { name: 'bar', prefix: '/', ... }]
+
+re.exec('/test/route')
+//=> ['/test/route', 'test', 'route']
+```
+
+**Please note:** Named parameters must be made up of "word characters" (`[A-Za-z0-9_]`).
+
+```js
+var re = pathToRegexp('/(apple-)?icon-:res(\\d+).png', keys)
+// keys = [{ name: 0, prefix: '/', ... }, { name: 'res', prefix: '', ... }]
+
+re.exec('/icon-76.png')
+//=> ['/icon-76.png', undefined, '76']
+```
+
+#### Modified Parameters
+
+##### Optional
+
+Parameters can be suffixed with a question mark (`?`) to make the parameter optional. This will also make the prefix optional.
+
+```js
+var re = pathToRegexp('/:foo/:bar?', keys)
+// keys = [{ name: 'foo', ... }, { name: 'bar', delimiter: '/', optional: true, repeat: false }]
+
+re.exec('/test')
+//=> ['/test', 'test', undefined]
+
+re.exec('/test/route')
+//=> ['/test', 'test', 'route']
+```
+
+##### Zero or more
+
+Parameters can be suffixed with an asterisk (`*`) to denote a zero or more parameter matches. The prefix is taken into account for each match.
+
+```js
+var re = pathToRegexp('/:foo*', keys)
+// keys = [{ name: 'foo', delimiter: '/', optional: true, repeat: true }]
+
+re.exec('/')
+//=> ['/', undefined]
+
+re.exec('/bar/baz')
+//=> ['/bar/baz', 'bar/baz']
+```
+
+##### One or more
+
+Parameters can be suffixed with a plus sign (`+`) to denote a one or more parameter matches. The prefix is taken into account for each match.
+
+```js
+var re = pathToRegexp('/:foo+', keys)
+// keys = [{ name: 'foo', delimiter: '/', optional: false, repeat: true }]
+
+re.exec('/')
+//=> null
+
+re.exec('/bar/baz')
+//=> ['/bar/baz', 'bar/baz']
+```
+
+#### Custom Match Parameters
+
+All parameters can be provided a custom regexp, which overrides the default (`[^\/]+`).
+
+```js
+var re = pathToRegexp('/:foo(\\d+)', keys)
+// keys = [{ name: 'foo', ... }]
+
+re.exec('/123')
+//=> ['/123', '123']
+
+re.exec('/abc')
+//=> null
+```
+
+**Please note:** Backslashes need to be escaped with another backslash in strings.
+
+#### Unnamed Parameters
+
+It is possible to write an unnamed parameter that only consists of a matching group. It works the same as a named parameter, except it will be numerically indexed.
+
+```js
+var re = pathToRegexp('/:foo/(.*)', keys)
+// keys = [{ name: 'foo', ... }, { name: 0, ... }]
+
+re.exec('/test/route')
+//=> ['/test/route', 'test', 'route']
+```
+
+#### Asterisk
+
+An asterisk can be used for matching everything. It is equivalent to an unnamed matching group of `(.*)`.
+
+```js
+var re = pathToRegexp('/foo/*', keys)
+// keys = [{ name: '0', ... }]
+
+re.exec('/foo/bar/baz')
+//=> ['/foo/bar/baz', 'bar/baz']
+```
+
+### Parse
+
+The parse function is exposed via `pathToRegexp.parse`. This will return an array of strings and keys.
+
+```js
+var tokens = pathToRegexp.parse('/route/:foo/(.*)')
+
+console.log(tokens[0])
+//=> "/route"
+
+console.log(tokens[1])
+//=> { name: 'foo', prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '[^\\/]+?' }
+
+console.log(tokens[2])
+//=> { name: 0, prefix: '/', delimiter: '/', optional: false, repeat: false, pattern: '.*' }
+```
+
+**Note:** This method only works with Express-style strings.
+
+### Compile ("Reverse" Path-To-RegExp)
+
+Path-To-RegExp exposes a compile function for transforming an Express-style path into a valid path.
+
+```js
+var toPath = pathToRegexp.compile('/user/:id')
+
+toPath({ id: 123 }) //=> "/user/123"
+toPath({ id: 'café' }) //=> "/user/caf%C3%A9"
+toPath({ id: '/' }) //=> "/user/%2F"
+
+toPath({ id: ':' }) //=> "/user/%3A"
+toPath({ id: ':' }, { pretty: true }) //=> "/user/:"
+
+var toPathRepeated = pathToRegexp.compile('/:segment+')
+
+toPathRepeated({ segment: 'foo' }) //=> "/foo"
+toPathRepeated({ segment: ['a', 'b', 'c'] }) //=> "/a/b/c"
+
+var toPathRegexp = pathToRegexp.compile('/user/:id(\\d+)')
+
+toPathRegexp({ id: 123 }) //=> "/user/123"
+toPathRegexp({ id: '123' }) //=> "/user/123"
+toPathRegexp({ id: 'abc' }) //=> Throws `TypeError`.
+```
+
+**Note:** The generated function will throw on invalid input. It will do all necessary checks to ensure the generated path is valid. This method only works with strings.
+
+### Working with Tokens
+
+Path-To-RegExp exposes the two functions used internally that accept an array of tokens.
+
+* `pathToRegexp.tokensToRegExp(tokens, options)` Transform an array of tokens into a matching regular expression.
+* `pathToRegexp.tokensToFunction(tokens)` Transform an array of tokens into a path generator function.
+
+#### Token Information
+
+* `name` The name of the token (`string` for named or `number` for index)
+* `prefix` The prefix character for the segment (`/` or `.`)
+* `delimiter` The delimiter for the segment (same as prefix or `/`)
+* `optional` Indicates the token is optional (`boolean`)
+* `repeat` Indicates the token is repeated (`boolean`)
+* `partial` Indicates this token is a partial path segment (`boolean`)
+* `pattern` The RegExp used to match this token (`string`)
+* `asterisk` Indicates the token is an `*` match (`boolean`)
+
+## Compatibility with Express <= 4.x
+
+Path-To-RegExp breaks compatibility with Express <= `4.x`:
+
+* No longer a direct conversion to a RegExp with sugar on top - it's a path matcher with named and unnamed matching groups
+  * It's unlikely you previously abused this feature, it's rare and you could always use a RegExp instead
+* All matching RegExp special characters can be used in a matching group. E.g. `/:user(.*)`
+  * Other RegExp features are not support - no nested matching groups, non-capturing groups or look aheads
+* Parameters have suffixes that augment meaning - `*`, `+` and `?`. E.g. `/:user*`
+
+## TypeScript
+
+Includes a [`.d.ts`](index.d.ts) file for TypeScript users.

+
+> Use package.json as a config store.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install pkg-store --save
+```
+
+Inherits [cache-base](https://github.com/jonschlinkert/cache-base), please see the `cache-base` documentation for more details.
+
+## Usage
+
+Pass the `cwd` and options to use, or an options object with `cwd` or `path`. If nothing is passed, the current working directory will be used.
+
+```js
+var pkg = require('pkg-store')(cwd, options);
+// or
+var pkg = require('pkg-store')(options);
+// or
+var pkg = require('pkg-store')();
+```
+
+**Example**
+
+```js
+var pkg = require('pkg-store')(process.cwd());
+```
+
+## API
+
+Inherits [cache-base](https://github.com/jonschlinkert/cache-base), please see the `cache-base` documentation for more details.
+
+### .set
+
+```js
+pkg.set(key, value);
+```
+
+Set property `key` with the given `value`.
+
+**Example**
+
+```js
+// given {"name": "my-project"}
+pkg.set('bin.foo', 'bar');
+
+console.log(pkg.data);
+//=> {"name": "my-project", "bin": {"foo": "bar"}}
+```
+
+### .save
+
+Persist package.json to the file system at `pkg.path`.
+
+```js
+pkg.save();
+```
+
+### .get
+
+```js
+pkg.get(key);
+```
+
+Get property `key` from package.json.
+
+**Example**
+
+```js
+// given {"name": "my-project"}
+pkg.set('bin.foo', 'bar');
+
+console.log(pkg.get('bin'));
+//=> {"foo": "bar"}
+```
+
+### .has
+
+```js
+pkg.has(key);
+```
+
+Returns `true` if `package.json` has property `key`.
+
+**Example**
+
+```js
+// given: {"name": "my-project"}
+console.log(pkg.has('name'));
+//=> true
+console.log(pkg.has('zzzzzzz'));
+//=> false
+```
+
+### .union
+
+```js
+pkg.union(key, val);
+```
+
+Create array `key`, or concatenate values to array `key`. Also uniquifies the array.
+
+**Example**
+
+```js
+pkg.union('keywords', 'foo');
+pkg.union('keywords', ['bar', 'baz']);
+
+console.log(pkg.get('keywords'));
+//=> ['foo', 'bar', 'baz']

+
+> Basic object cache with `get`, `set`, `del`, and `has` methods for node.js/javascript projects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save cache-base
+```
+
+## Usage
+
+```js
+var Cache = require('cache-base');
+
+// instantiate
+var app = new Cache();
+
+// set values
+app.set('a', 'b');
+app.set('c.d', 'e');
+
+// get values
+app.get('a');
+//=> 'b'
+app.get('c');
+//=> {d: 'e'}
+
+console.log(app.cache);
+//=> {a: 'b'}
+```
+
+**Inherit**
+
+```js
+var util = require('util');
+var Cache = require('cache-base');
+
+function MyApp() {
+  Cache.call(this);
+}
+util.inherits(MyApp, Cache);
+
+var app = new MyApp();
+app.set('a', 'b');
+app.get('a');
+//=> 'b'
+```
+
+**Namespace**
+
+Define a custom property for storing values.
+
+```js
+var Cache = require('cache-base').namespace('data');
+var app = new Cache();
+app.set('a', 'b');
+console.log(app.data);
+//=> {a: 'b'}
+```
+
+## API
+
+### [namespace](index.js#L21)
+
+Create a `Cache` constructor that when instantiated will store values on the given `prop`.
+
+**Params**
+
+* `prop` **{String}**: The property name to use for storing values.
+* `returns` **{Function}**: Returns a custom `Cache` constructor
+
+**Example**
+
+```js
+var Cache = require('cache-base').namespace('data');
+var cache = new Cache();
+
+cache.set('foo', 'bar');
+//=> {data: {foo: 'bar'}}
+```
+
+### [Cache](index.js#L35)
+
+Create a new `Cache`. Internally the `Cache` constructor is created using the `namespace` function, with `cache` defined as the storage object.
+
+**Params**
+
+* `cache` **{Object}**: Optionally pass an object to initialize with.
+
+**Example**
+
+```js
+var app = new Cache();
+```
+
+### [.set](index.js#L76)
+
+Assign `value` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `set` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.on('set', function(key, val) {
+  // do something when `set` is emitted
+});
+
+app.set(key, value);
+
+// also takes an object or array
+app.set({name: 'Halle'});
+app.set([{foo: 'bar'}, {baz: 'quux'}]);
+console.log(app);
+//=> {name: 'Halle', foo: 'bar', baz: 'quux'}
+```
+
+### [.union](index.js#L106)
+
+Union `array` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+app.union('a.b', ['foo']);
+app.union('a.b', ['bar']);
+console.log(app.get('a'));
+//=> {b: ['foo', 'bar']}
+```
+
+### [.get](index.js#L136)
+
+Return the value of `key`. Dot notation may be used to get [nested property values](https://github.com/jonschlinkert/get-value).
+
+**Params**
+
+* `key` **{String}**: The name of the property to get. Dot-notation may be used.
+* `returns` **{any}**: Returns the value of `key`
+
+**Events**
+
+* `emits`: `get` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.set('a.b.c', 'd');
+app.get('a.b');
+//=> {c: 'd'}
+
+app.get(['a', 'b']);
+//=> {c: 'd'}
+```
+
+### [.has](index.js#L163)
+
+Return true if app has a stored value for `key`, false only if value is `undefined`.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{Boolean}**
+
+**Events**
+
+* `emits`: `has` with `key` and true or false as arguments.
+
+**Example**
+
+```js
+app.set('foo', 'bar');
+app.has('foo');
+//=> true
+```
+
+### [.del](index.js#L191)
+
+Delete one or more properties from the instance.
+
+**Params**
+
+* `key` **{String|Array}**: Property name or array of property names.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `del` with the `key` as the only argument.
+
+**Example**
+
+```js
+app.del(); // delete all
+// or
+app.del('foo');
+// or
+app.del(['foo', 'bar']);
+```
+
+### [.clear](index.js#L210)
+
+Reset the entire cache to an empty object.
+
+**Example**
+
+```js
+app.clear();
+```
+
+### [.visit](index.js#L227)
+
+Visit `method` over the properties in the given object, or map
+visit over the object-elements in an array.
+
+**Params**
+
+* `method` **{String}**: The name of the `base` method to call.
+* `val` **{Object|Array}**: The object or array to iterate over.
+* `returns` **{Object}**: Returns the instance for chaining.

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+
+Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## Assign or Merge vs. Visit
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend`:
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. But **if you also want to emit an event** each time a property is added to the `data` object. A better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach, when an array is passed to `set`, `mapVisit` calls `set` on each object in the array. When an object is passed, `visit` calls `set` on each property in the object. As a result, the `data` event will be emitted every time a property is added to `data`.
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // some event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save lazy-cache
+```
+
+## Heads up!
+
+It's suprising how many libraries are in the average dependency tree that don't belong there for one reason or another. Either because they were accidentally listed as `dependencies` instead of `devDepedencies`, or they are required in a file as variables, but the variable is never actually used (poor linting), and so on. Or because the maintainer made the decision to add the deps, even though they will never ([or can't ever](https://github.com/felixge/node-dateformat/issues/36)) be used by 99.9% of users.
+
+Worse, many libraries like chalk and [shelljs](https://github.com/eslint/eslint/issues/7316) actually execute code when `require()` is called!? (shelljs was modifying the `String.prototype`, and chalk loops over some objects to dynamically create methods). In other words, they do something like this:
+
+```js
+// in the main export of a library, if you do this it will
+// automatically modify the String.prototype _globally_, 
+// the moment node.js loads the dependency tree
+String.prototype.foo = function() {};
+
+// same if you do something like this
+// (dont' do this, ever. wrap this kind of code in a function
+// and allow implementors to decide when to call it)
+while (foo) {
+  // do stuff
+}
+```
+
+In any case, just having these libraries in your dependency tree somewhere means that their code will excecute the moment you run your application _even if the libraries are never called by your application or any other code anywhere in the tree_.
+
+**solution**
+
+lazy-cache doesn't use any "magic", it uses native, plain-vanilla, tried and true javascript getters to call node's `require()` system.
+
+**Faster, safer code**
+
+There main advantage to this, the main is that `require`s are loaded on demand, so only code that is actually used will ever be loaded. As a result, applications will load faster (sometimes much faster - we've seen load times drop from ~1 second to less than 50 milliseconds).
+
+Moreover, in some cases this also avoids inadvertently loading libraries that execute code or modifies globals, etc.
+
+**webpack users**
+
+If you use webpack and are experiencing issues with lazy-cache, this is a known bug caused by webpack, not lazy-cache. There is a solution though, you can use [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that _fixes the webpack bug_.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+Dot notation may also be used in the alias to create an object hierarchy.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+utils('ansi-cyan', 'color.cyan');
+utils('ansi-yellow', 'color.yellow');
+utils('ansi-magenta', 'color.magenta');
+console.log(utils.color.cyan('foo'));
+console.log(utils.color.yellow('bar'));
+console.log(utils.color.magenta('baz'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+var obj = {a: {b: {c: 'd', e: 'f'}}};
+unset(obj, 'a.b.c');
+console.log(obj);
+//=> {a: {b: {e: 'f'}}};
+```
+
+## Examples
+
+### Updates the object when a property is deleted
+
+```js
+var obj = {a: 'b'};
+unset(obj, 'a');
+console.log(obj);
+//=> {}
+```
+
+### Returns true when a property is deleted
+
+```js
+unset({a: 'b'}, 'a') // true
+```
+
+### Returns `true` when a property does not exist
+
+This is consistent with `delete` behavior in that it does not
+throw when a property does not exist.
+
+```js
+unset({a: {b: {c: 'd'}}}, 'd') // true
+```
+
+### delete nested values
+
+```js
+var one = {a: {b: {c: 'd'}}};
+unset(one, 'a.b');
+console.log(one);
+//=> {a: {}}
+
+var two = {a: {b: {c: 'd'}}};
+unset(two, 'a.b.c');
+console.log(two);
+//=> {a: {b: {}}}
+
+var three = {a: {b: {c: 'd', e: 'f'}}};
+unset(three, 'a.b.c');
+console.log(three);
+//=> {a: {b: {e: 'f'}}}
+```
+
+### throws on invalid args
+
+```js
+unset();
+// 'expected an object.'
+```

+
+Useful for protecting tokens, like templates in HTML, from being mutated when the string is transformed in some way, like from a formatter/beautifier.
+
+**Example without `preserve`**
+
+Let's say you want to use [js-beautify] on a string of html with Lo-Dash/Underscore templates, such as: `<ul><li><%= name %></li></ul>`:
+
+js-beautify will render the template unusable (and apply incorrect formatting because of the unfamiliar syntax from the Lo-Dash template):
+
+```html
+<ul>
+  <li>
+    <%=n ame %>
+  </li>
+</ul>
+```
+
+**Example with `preserve`**
+
+Correct.
+
+```html
+<ul>
+  <li><%= name %></li>
+</ul>
+```
+
+For the record, this is just a random example, I've had very few issues with js-beautify in general. But with or without js-beautify, this kind of token mangling does happen sometimes when you use formatters, beautifiers or similar tools.

+  <li><%= name %></li>
+</ul>
+```
+
+For the record, this is just a random example, I've had very few issues with js-beautify in general. But with or without js-beautify, this kind of token mangling does happen sometimes when you use formatters, beautifiers or similar tools.

+# pretty-time [![NPM version](https://badge.fury.io/js/pretty-time.svg)](http://badge.fury.io/js/pretty-time)  [![Build Status](https://travis-ci.org/jonschlinkert/pretty-time.svg)](https://travis-ci.org/jonschlinkert/pretty-time)
+
+> Easily format the time from node.js `process.hrtime`. Works with timescales ranging from weeks to nanoseconds.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i pretty-time --save
+```
+
+## Usage
+
+```js
+var pretty = require('pretty-time');
+
+var start = process.hrtime();
+var time = process.hrtime(start);
+console.log(pretty(time));
+//=> 3μs
+```
+
+## API
+
+By default, when no time increment is given as the second argument, the closest timescale is used (e.g. _most granular without being less than zero_).
+
+**Examples:**
+
+```js
+pretty([1200708, 795428088]);
+//=> '2w'
+
+pretty([800708, 795428088]);
+//=> '1w'
+
+pretty([400708, 795428088]);
+//=> '5d'
+
+pretty([70708, 795428088]);
+//=> '20h'
+
+pretty([12708, 795428088]);
+//=> '4h'
+
+pretty([3708, 795428088]);
+//=> '1h'
+
+pretty([208, 795428088]);
+//=> '3m'
+
+pretty([20, 795428088]);
+//=> '21s'
+
+pretty([0, 795428088]);
+//=> '795ms'
+
+pretty([0, 000428088]);
+//=> '428μs'
+
+pretty([0, 000000088]);
+//=> '88ns'
+
+pretty([0, 000000018]);
+//=> '18ns'
+```
+
+### Minimum time increment
+
+_(All of the following examples use `[6740, 795428088]` as the hrtime array.)_
+
+This value is passed as the second argument and determines how granular to make the time.
+
+**Examples**
+
+```js
+pretty(time, 'h');
+//=> '2h'
+
+pretty(time, 'm');
+//=> '1h 52m'
+
+pretty(time, 's');
+//=> '1h 52m 21s'
+```
+
+**Valid time increments**
+
+Any of the following may be used:
+
+* `ns` | `nano` | `nanosecond` | `nanoseconds`
+* `μs` | `micro` | `microsecond` | `microseconds`
+* `ms` | `milli` | `millisecond` | `milliseconds`
+* `s` | `sec` | `second` | `seconds`
+* `m` | `min` | `minute` | `minutes`
+* `h` | `hr` | `hour` | `hours`
+* `d` | `day` | `days`
+* `w` | `wk` | `week` | `weeks`

+
+Get the name of a project, from package.json, git config, or basename of the current working directory.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save project-name
+```
+
+## Usage
+
+The project name is resolved in this order:
+
+1. check for package.json, if exists `name` is returned
+2. check for git repository, if exists return repository `name`
+3. use the `path.basename` of the current working directory
+
+```js
+var name = require('project-name');
+name();
+//=> project-name
+```
+
+Optionally specify a current working directory:
+
+```js
+var name = require('project-name');
+name('foo');
+```

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+> Easily add plugin support to your node.js application.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save use
+```
+
+A different take on plugin handling! This is not a middleware system, if you need something that handles async middleware, [ware](https://github.com/segmentio/ware) is great for that.
+
+## Usage
+
+```js
+var use = require('use');
+```
+
+See the [examples folder](./examples) for usage examples.

+
+> Generate randomized strings of a specified length using simple character sequences. The original generate-password.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save randomatic
+```
+
+## Usage
+
+```js
+var randomize = require('randomatic');
+```
+
+## API
+
+```js
+randomize(pattern, length, options);
+randomize.isCrypto;
+```
+
+* `pattern` **{String}**: (required) The pattern to use for randomizing
+* `length` **{Number}**: (optional) The length of the string to generate
+* `options` **{Object}**: (optional) See available [options](#options)
+* `randomize.isCrypto` will be `true` when a cryptographically secure function is being used to generate random numbers. The value will be `false` when the function in use is `Math.random`.
+
+### pattern
+
+> The pattern to use for randomizing
+
+Patterns can contain any combination of the below characters, specified in any order.
+
+**Example:**
+
+To generate a 10-character randomized string using all available characters:
+
+```js
+randomize('*', 10);
+//=> 'x2_^-5_T[$'
+
+randomize('Aa0!', 10);
+//=> 'LV3u~BSGhw'
+```
+
+* `a`: Lowercase alpha characters (`abcdefghijklmnopqrstuvwxyz'`)
+* `A`: Uppercase alpha characters (`ABCDEFGHIJKLMNOPQRSTUVWXYZ'`)
+* `0`: Numeric characters (`0123456789'`)
+* `!`: Special characters (`~!@#$%^&()_+-={}[];\',.`)
+* `*`: All characters (all of the above combined)
+* `?`: Custom characters (pass a string of custom characters to the options)
+
+### length
+
+> The length of the string to generate
+
+**Examples:**
+
+* `randomize('A', 5)` will generate a 5-character, uppercase, alphabetical, randomized string, e.g. `KDJWJ`.
+* `randomize('0', 2)` will generate a 2-digit random number
+* `randomize('0', 3)` will generate a 3-digit random number
+* `randomize('0', 12)` will generate a 12-digit random number
+* `randomize('A0', 16)` will generate a 16-character, alpha-numeric randomized string
+
+If `length` is left undefined, the length of the pattern in the first parameter will be used. For example:
+
+* `randomize('00')` will generate a 2-digit random number
+* `randomize('000')` will generate a 3-digit random number
+* `randomize('0000')` will generate a 4-digit random number...
+* `randomize('AAAAA')` will generate a 5-character, uppercase alphabetical random string...
+
+These are just examples, [see the tests](./test.js) for more use cases and examples.
+
+## options
+
+> These are options that can be passed as the third argument.
+
+#### chars
+
+Type: `String`
+
+Default: `undefined`
+
+Define a custom string to be randomized.
+
+**Example:**
+
+* `randomize('?', 20, {chars: 'jonschlinkert'})` will generate a 20-character randomized string from the letters contained in `jonschlinkert`.
+* `randomize('?', {chars: 'jonschlinkert'})` will generate a 13-character randomized string from the letters contained in `jonschlinkert`.
+
+#### exclude
+
+Type: `String|Array`
+
+Default: `undefined`
+
+Specify a string or array of characters can are excluded from the possible characters used to generate the randomized string.
+
+**Example:**
+
+* `randomize('*', 20, { exclude: '0oOiIlL1' })` will generate a 20-character randomized string using all of possible characters except for `0oOiIlL1`.
+
+## Usage Examples
+
+* `randomize('A', 4)` (_whitespace insenstive_) would result in randomized 4-digit uppercase letters, like, `ZAKH`, `UJSL`... etc.
+* `randomize('AAAA')` is equivelant to `randomize('A', 4)`
+* `randomize('AAA0')` and `randomize('AA00')` and `randomize('A0A0')` are equivelant to `randomize('A0', 4)`
+* `randomize('aa')`: results in double-digit, randomized, lower-case letters (`abcdefghijklmnopqrstuvwxyz`)
+* `randomize('AAA')`: results in triple-digit, randomized, upper-case letters (`ABCDEFGHIJKLMNOPQRSTUVWXYZ`)
+* `randomize('0', 6)`: results in six-digit, randomized numbers (`0123456789`)
+* `randomize('!', 5)`: results in single-digit randomized, _valid_ non-letter characters (`~!@#$%^&()_+-={}[]
+* `randomize('A!a0', 9)`: results in nine-digit, randomized characters (any of the above)
+
+_The order in which the characters are defined is insignificant._

+
+## Usage
+
+To understand some of the rationale behind the decisions made in this library (and to learn about some oddities of number evaluation in JavaScript), [see this gist](https://gist.github.com/jonschlinkert/e30c70c713da325d0e81).
+
+```js
+var isNumber = require('is-number');
+```
+
+### true
+
+See the [tests](./test.js) for more examples.
+
+```js
+isNumber(5e3)      //=> 'true'
+isNumber(0xff)     //=> 'true'
+isNumber(-1.1)     //=> 'true'
+isNumber(0)        //=> 'true'
+isNumber(1)        //=> 'true'
+isNumber(1.1)      //=> 'true'
+isNumber(10)       //=> 'true'
+isNumber(10.10)    //=> 'true'
+isNumber(100)      //=> 'true'

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly identifies instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```

+# read-file [![NPM version](https://badge.fury.io/js/read-file.svg)](http://badge.fury.io/js/read-file)
+
+> Thin wrapper around fs.readFile and fs.readFileSync that also strips byte order marks when `utf8` encoding is chosen. Also optionally replaces windows newlines with unix newlines.
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i read-file --save
+```
+
+## Usage
+
+```js
+var read = require('read-file');
+
+// async
+read('foo.txt', function(err, buffer) {
+  //=> <Buffer 74 68 69 73 20 69 73 20 66 6f 6f>
+});
+
+// sync
+var buffer = read.sync('foo.txt');
+//=> <Buffer 74 68 69 73 20 69 73 20 66 6f 6f>
+```
+
+### BOM
+
+if `utf8` encoding is used, byte order marks will be stripped
+
+**async**
+
+```js
+read('foo.txt', 'utf8', function(err, buffer) {
+  //=> 'some contents...'
+});
+
+// or
+read('foo.txt', {encoding: 'utf8'} function(err, buffer) {
+  //=> 'some contents...'
+});
+```
+
+**sync**
+
+```js
+read.sync('foo.txt', 'utf8');
+// or
+read('foo.txt', {encoding: 'utf8'});
+```
+
+### options.normalize
+
+Pass `{ normalize: true }` on the options to strip windows carriage returns. This will also return a `utf8` string.

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+* **GitHub Issue**: https://github.com/iojs/readable-stream/issues/106
+* **Original Minutes Google Doc**: https://docs.google.com/document/d/17aTgLnjMXIrfjgNaTUnHQO7m3xgzHR2VXBTmi03Qii4/
+
+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+This module include fixes seen in later version (0.11-0.12 and iojs) and ease some undesirable behavior one could see using the readline to create interatives prompts. This means `readline2` change some behaviors and as so is **not** meant to be an exact drop-in replacement.
+
+This project is extracted from the core of [Inquirer.js interactive prompt interface](https://github.com/SBoudrias/Inquirer.js) to be available as a standalone module.
+
+
+Documentation
+-------------
+
+**Installation**: `npm install --save readline2`
+
+### readline2.createInterface(options); -> {Interface}
+
+Present the same API as [Node.js `readline.createInterface()`](http://nodejs.org/api/readline.html)
+
+#### Improvements
+- Default `options.input` as `process.stdin`
+- Default `options.output` as `process.stdout`
+- `interface.stdout` is wrapped in a [MuteStream](https://github.com/isaacs/mute-stream)
+- Prevent `up` and `down` keys from moving through history inside the readline
+- Fix cursor position after a line refresh when the `Interface` prompt contains ANSI colors
+- Correctly return the cursor position when faced with implicit line returns

+# reduce-object [![NPM version](https://badge.fury.io/js/reduce-object.svg)](http://badge.fury.io/js/reduce-object)
+
+> Reduces an object to a value that is the accumulated result of running each property in the object through a callback.
+
+## Install
+#### Install with [npm](npmjs.org):
+
+```bash
+npm i reduce-object --save
+```
+
+## Run tests
+
+```bash
+npm test
+```
+
+## Usage
+
+Executes the callback function once for each own enumerable property in the object, receiving four arguments:
+
+  - `acc`: the initial value (or value from the previous callback call),
+  - `value`: the of the current property,
+  - `key`: the of the current property, and
+  - the original `object` over which the function is iterating.
+
+```js
+var reduce = require('reduce-object');
+
+var a = {a: 'foo', b: 'bar', c: {}};
+
+var obj = reduce(a, function (acc, value, key, orig) {
+  if (typeof value === 'object') {
+    acc[key] = {what: 'huh?'};
+  } else {
+    acc[key] = value.toUpperCase(); // why?
+  }
+  return acc;
+}, {});
+
+console.log(obj);
+//=> {a: 'FOO', b: 'BAR', c: {what: 'huh?'}};
+```

+
+> Memoize the results of a call to the RegExp constructor, avoiding repetitious runtime compilation of the same string and options, resulting in surprising performance improvements.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save regex-cache
+```
+
+* Read [what this does](#what-this-does).
+* See [the benchmarks](#benchmarks)
+
+## Usage
+
+Wrap a function like this:
+
+```js
+var cache = require('regex-cache');
+var someRegex = cache(require('some-regex-lib'));
+```
+
+**Caching a regex**
+
+If you want to cache a regex after calling `new RegExp()`, or you're requiring a module that returns a regex, wrap it with a function first:
+
+```js
+var cache = require('regex-cache');
+
+function yourRegex(str, opts) {
+  // do stuff to str and opts
+  return new RegExp(str, opts.flags);
+}
+
+var regex = cache(yourRegex);
+```
+
+## Recommendations
+
+### Use this when...
+
+* **No options are passed** to the function that creates the regex. Regardless of how big or small the regex is, when zero options are passed, caching will be faster than not.
+* **A few options are passed**, and the values are primitives. The limited benchmarks I did show that caching is beneficial when up to 8 or 9 options are passed.
+
+### Do not use this when...
+
+* **The values of options are not primitives**. When non-primitives must be compared for equality, the time to compare the options is most likely as long or longer than the time to just create a new regex.
+
+### Example benchmarks
+
+Performance results, with and without regex-cache:
+
+```bash
+# no args passed (defaults)
+  with-cache x 8,699,231 ops/sec ±0.86% (93 runs sampled)
+  without-cache x 2,777,551 ops/sec ±0.63% (95 runs sampled)
+
+# string and six options passed
+  with-cache x 1,885,934 ops/sec ±0.80% (93 runs sampled)
+  without-cache x 1,256,893 ops/sec ±0.65% (97 runs sampled)
+
+# string only
+  with-cache x 7,723,256 ops/sec ±0.87% (92 runs sampled)
+  without-cache x 2,303,060 ops/sec ±0.47% (99 runs sampled)
+
+# one option passed
+  with-cache x 4,179,877 ops/sec ±0.53% (100 runs sampled)
+  without-cache x 2,198,422 ops/sec ±0.47% (95 runs sampled)
+
+# two options passed
+  with-cache x 3,256,222 ops/sec ±0.51% (99 runs sampled)
+  without-cache x 2,121,401 ops/sec ±0.79% (97 runs sampled)
+
+# six options passed
+  with-cache x 1,816,018 ops/sec ±1.08% (96 runs sampled)
+  without-cache x 1,157,176 ops/sec ±0.53% (100 runs sampled)
+
+# 
+# diminishing returns happen about here
+# 
+
+# ten options passed
+  with-cache x 1,210,598 ops/sec ±0.56% (92 runs sampled)
+  without-cache x 1,665,588 ops/sec ±1.07% (100 runs sampled)
+
+# twelve options passed
+  with-cache x 1,042,096 ops/sec ±0.68% (92 runs sampled)
+  without-cache x 1,389,414 ops/sec ±0.68% (97 runs sampled)
+
+# twenty options passed
+  with-cache x 661,125 ops/sec ±0.80% (93 runs sampled)
+  without-cache x 1,208,757 ops/sec ±0.65% (97 runs sampled)
+
+# 
+# when non-primitive values are compared
+# 
+
+# single value on the options is an object
+  with-cache x 1,398,313 ops/sec ±1.05% (95 runs sampled)
+  without-cache x 2,228,281 ops/sec ±0.56% (99 runs sampled)
+```
+
+## Run benchmarks
+
+Install dev dependencies:
+
+```bash
+npm i -d && npm run benchmarks
+```
+
+## What this does
+
+If you're using `new RegExp('foo')` instead of a regex literal, it's probably because you need to dyamically generate a regex based on user options or some other potentially changing factors.
+
+When your function creates a string based on user inputs and passes it to the `RegExp` constructor, regex-cache caches the results. The next time the function is called if the key of a cached regex matches the user input (or no input was given), the cached regex is returned, avoiding unnecessary runtime compilation.
+
+Using the RegExp constructor offers a lot of flexibility, but the runtime compilation comes at a price - it's slow. Not specifically because of the call to the RegExp constructor, but **because you have to build up the string before `new RegExp()` is even called**.

+# relative [![NPM version](https://badge.fury.io/js/relative.svg)](http://badge.fury.io/js/relative)
+
+> Get the relative filepath from path A to path B. Calculates from file-to-directory, file-to-file, directory-to-file, and directory-to-directory.
+
+**Calculates correctly from:**
+
+* file-to-directory
+* file-to-file
+* directory-to-file
+* directory-to-directory
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i relative --save
+```
+
+## Usage
+
+```js
+var relative = require('relative');
+relative(from, to);
+
+relative('a/b/c.txt', 'd');
+//=> '../../d'
+
+relative('d', 'a/b/c.txt');
+//=> '../a/b/c.txt'
+```
+
+Relative to `process.cwd()`
+
+```js
+relative('a/b/c.txt');
+//=> 'a/b/c.txt'
+
+relative(process.cwd(), 'a/b/c.txt');
+//=> 'a/b/c.txt'
+
+relative('a/b/c.txt', process.cwd());
+//=> '..'
+```
+
+### stat
+
+There are cases where it is impossible to tell if a path is a file or a directory without more information.
+
+**Examples**
+
+If assume that `a.b.c` is a directory, we have no way of know that without hitting the filesystem, which is impossible if the path doesn't actually exist.
+
+So the result would be:
+
+```js
+relative('fixtures/a.b.c', 'fixtures');
+//=> '.'
+```
+
+**If the path exists**
+
+Pass `true` as the last argument, or pass the stat object from `fs.stat()`/`fs.statSync()` and you will get the correct result.
+
+```js
+relative('fixtures/a.b.c', 'fixtures', true);
+//=> '..'
+```
+
+**If the path does not exist**
+
+End directory names with trailing slash. If you can't or don't want to do that, you may get incorrect results from time to time, but there isn't much we can do about it.
+
+One very bad idea I had was to create a whitelist of filenames that look like directories, and directories that look like file names so that when those paths are encountered the logic would be adjusted accordingly. Anyway, it is what it is.
+
+## relative.toBase()
+
+Get the relative path to the given `base`.
+
+```js
+relative.toBase(base, filepath);
+```
+
+**Example**:
+
+```js
+relative.toBase('a/b', 'a/b/c/d/file.txt');
+//=> 'c/d/file.txt'
+```
+

+* [global-prefix](https://github.com/jonschlinkert/global-prefix): Get the npm global path prefix.
+* [is-absolute](https://github.com/jonschlinkert/is-absolute): Return true if a file path is absolute.
+* [is-relative](https://github.com/jonschlinkert/is-relative): Returns `true` if the path appears to be relative.
+* [is-dotfile](https://github.com/jonschlinkert/is-dotfile): Return true if a file path is (or has) a dotfile.

+[![NPM version][npm-img]][npm-url] [![Build Status: Linux][travis-img]][travis-url] [![Build Status: Windows][appveyor-img]][appveyor-url] [![Coverage Status][coveralls-img]][coveralls-url]
+
+Removes all separators from the end of a string.
+
+## Install
+
+```
+npm install remove-trailing-separator
+```
+
+## Examples
+
+```js
+const removeTrailingSeparator = require('remove-trailing-separator');
+
+removeTrailingSeparator('/foo/bar/')   // '/foo/bar'
+removeTrailingSeparator('/foo/bar///') // '/foo/bar'
+
+// leaves only/last separator
+removeTrailingSeparator('/')    // '/'
+removeTrailingSeparator('///')  // '/'
+
+// returns empty string
+removeTrailingSeparator('') // ''
+```
+
+## Notable backslash, or win32 separator behavior
+
+`\` is considered a separator only on WIN32 systems. All POSIX compliant systems
+see backslash as a valid file name character, so it would break POSIX compliance
+to remove it there.
+
+In practice, this means that this code will return different things depending on
+what system it runs on:
+
+```js
+removeTrailingSeparator('\\foo\\')
+// UNIX  => '\\foo\\'
+// WIN32 => '\\foo'
+```

+
+> Repeat the given string n times. Fastest implementation for repeating a string.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save repeat-string
+```
+
+## Usage
+
+### [repeat](index.js#L41)
+
+Repeat the given `string` the specified `number` of times.
+
+**Example:**
+
+**Example**
+
+```js
+var repeat = require('repeat-string');
+repeat('A', 5);
+//=> AAAAA
+```
+
+**Params**
+
+* `string` **{String}**: The string to repeat
+* `number` **{Number}**: The number of times to repeat the string
+* `returns` **{String}**: Repeated string
+
+## Benchmarks
+
+Repeat string is significantly faster than the native method (which is itself faster than [repeating](https://github.com/sindresorhus/repeating)):

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+> Ensures that absolute file paths are always returned from a glob pattern or array of glob patterns.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save resolve-glob
+```
+
+## Usage
+
+```js
+var glob = require('resolve-glob');
+```
+
+See [matched](https://github.com/jonschlinkert/matched) for the full range of features and options.
+
+**async**
+
+```js
+glob(['*.js'], function(err, files) {
+  console.log(files[0])
+  //=> '/Users/jonschlinkert/dev/resolve-glob/index.js'
+});
+```
+
+**sync**
+
+```js
+var files = glob.sync(['*.js']);
+console.log(files[0])
+//=> '/Users/jonschlinkert/dev/resolve-glob/index.js'
+```
+
+### cwd expansion
+
+The following characters are expanded to directories with [resolve-dir](https://github.com/jonschlinkert/resolve-dir) when used as leading characters in `options.cwd`:
+
+* `~`: expanded to the user home directory
+* `@`: expanded to global npm modules directory
+
+See [resolve-dir](https://github.com/jonschlinkert/resolve-dir) for more details.

+
+> Return true if a value is a valid glob pattern or patterns.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-valid-glob
+```
+
+## Usage
+
+This really just checks to make sure that a pattern is either a string or array, and if it's an array it's either empty or consists of only strings.
+
+```js
+var isValidGlob = require('is-valid-glob');
+
+isValidGlob('foo/*.js');
+//=> true
+```
+
+**Valid patterns**
+
+```js
+isValidGlob('a');
+isValidGlob('a.js');
+isValidGlob('*.js');
+isValidGlob(['a', 'b']);
+//=> all true
+```
+
+**Invalid patterns**
+
+```js
+isValidGlob();
+isValidGlob('');
+isValidGlob(null);
+isValidGlob(undefined);
+isValidGlob(new Buffer('foo'));
+isValidGlob(['foo', [[]]]);
+isValidGlob(['foo', [['bar']]]);
+isValidGlob(['foo', {}]);
+isValidGlob({});
+isValidGlob([]);
+isValidGlob(['']);
+//=> all false
+```

+# resolve
+
+implements the [node `require.resolve()`
+algorithm](https://nodejs.org/api/modules.html#modules_all_together)
+such that you can `require.resolve()` on behalf of a file asynchronously and
+synchronously
+
+[![build status](https://secure.travis-ci.org/browserify/resolve.png)](http://travis-ci.org/browserify/resolve)
+
+# example
+
+asynchronously resolve:
+
+```js
+var resolve = require('resolve');
+resolve('tap', { basedir: __dirname }, function (err, res) {
+    if (err) console.error(err);
+    else console.log(res);
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+```js
+var resolve = require('resolve');
+var res = resolve.sync('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+```js
+var resolve = require('resolve');
+```
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* opts.isDirectory - function to asynchronously test whether a directory exists
+
+* `opts.packageFilter(pkg, pkgfile, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * pkgfile - path to package.json
+  * dir - directory for package.json
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
+This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
+**Note:** this property is currently `true` by default but it will be changed to
+`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.
+
+default `opts` values:
+
+```js
+{
+    paths: [],
+    basedir: __dirname,
+    extensions: ['.js'],
+    readFile: fs.readFile,
+    isFile: function isFile(file, cb) {
+        fs.stat(file, function (err, stat) {
+            if (!err) {
+                return cb(null, stat.isFile() || stat.isFIFO());
+            }
+            if (err.code === 'ENOENT' || err.code === 'ENOTDIR') return cb(null, false);
+            return cb(err);
+        });
+    },
+    isDirectory: function isDirectory(dir, cb) {
+        fs.stat(dir, function (err, stat) {
+            if (!err) {
+                return cb(null, stat.isDirectory());
+            }
+            if (err.code === 'ENOENT' || err.code === 'ENOTDIR') return cb(null, false);
+            return cb(err);
+        });
+    },
+    moduleDirectory: 'node_modules',
+    preserveSymlinks: true
+}
+```
+
+## resolve.sync(id, opts)
+
+Synchronously resolve the module path string `id`, returning the result and
+throwing an error when `id` can't be resolved.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files synchronously
+
+* opts.isFile - function to synchronously test whether a file exists
+
+* opts.isDirectory - function to synchronously test whether a directory exists
+
+* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * dir - directory for package.json (Note: the second argument will change to "pkgfile" in v2)
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+Install dev dependencies:
+
+```sh
+$ npm i -d && npm test
+```

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+// Approach:
+//
+// 1. Get the minimatch set
+// 2. For each pattern in the set, PROCESS(pattern, false)
+// 3. Store matches per-set, then uniq them
+//
+// PROCESS(pattern, inGlobStar)
+// Get the first [n] items from pattern that are all strings
+// Join these together.  This is PREFIX.
+//   If there is no more remaining, then stat(PREFIX) and
+//   add to matches if it succeeds.  END.
+//
+// If inGlobStar and PREFIX is symlink and points to dir
+//   set ENTRIES = []
+// else readdir(PREFIX) as ENTRIES
+//   If fail, END
+//
+// with ENTRIES
+//   If pattern[n] is GLOBSTAR
+//     // handle the case where the globstar match is empty
+//     // by pruning it out, and testing the resulting pattern
+//     PROCESS(pattern[0..n] + pattern[n+1 .. $], false)
+//     // handle other cases.
+//     for ENTRY in ENTRIES (not dotfiles)
+//       // attach globstar + tail onto the entry
+//       // Mark that this entry is a globstar match
+//       PROCESS(pattern[0..n] + ENTRY + pattern[n .. $], true)
+//
+//   else // not globstar
+//     for ENTRY in ENTRIES (not dotfiles, unless pattern[n] is dot)
+//       Test ENTRY against pattern[n]
+//       If fails, continue
+//       If passes, PROCESS(pattern[0..n] + item + pattern[n+1 .. $])
+//
+// Caveat:
+//   Cache all stats and readdirs results to minimize syscall.  Since all
+//   we ever care about is existence and directory-ness, we can just keep
+//   `true` for files, and [children,...] for directories, or `false` for
+//   things that don't exist.

+Run Async
+=========
+
+[![npm](https://badge.fury.io/js/run-async.svg)](http://badge.fury.io/js/run-async) [![tests](https://travis-ci.org/SBoudrias/run-async.svg?branch=master)](http://travis-ci.org/SBoudrias/run-async) [![dependencies](https://david-dm.org/SBoudrias/run-async.svg?theme=shields.io)](https://david-dm.org/SBoudrias/run-async)
+
+Utility method to run function either synchronously or asynchronously using the common `this.async()` style.
+
+This is useful for library author accepting sync or async functions as parameter. `runAsync` will always run them as async method, and normalize the function handling.
+
+Installation
+=========
+
+```bash
+npm install --save run-async
+```
+
+Usage
+=========
+
+```js
+var runAsync = require('run-async');
+
+// In Async mode:
+var asyncFn = function (a) {
+  var done = this.async();
+
+  setTimeout(function () {
+    done('running: ' + a);
+  }, 10);
+};
+
+runAsync(asyncFn, function (answer) {
+  console.log(answer); // 'running: async'
+}, 'async');
+
+// In Sync mode:
+var syncFn = function (a) {
+  return 'running: ' + a;
+};
+
+runAsync(asyncFn, function (answer) {
+  console.log(answer); // 'running: sync'
+}, 'sync');
+```

+# RxJS Lite Module #
+
+The Reactive Extensions for JavaScript Lite version is a lightweight version of the Reactive Extensions for JavaScript which covers most of the day to day operators you might use all in a single library.  Functionality such as bridging to events, promises, callbacks, Node.js-style callbacks, time-based operations and more are built right in.  This comes with `rx.lite.js` which is for use in modern development environments such as > IE9 and server-side environments such as Node.js.
+
+## Getting Started
+
+There are a number of ways to get started with RxJS.
+
+### Installing with [NPM](https://npmjs.org/)
+
+```bash`
+$ npm install rx-lite
+$ npm install -g rx-lite
+```
+
+### Using with Node.js and Ringo.js
+
+```js
+var Rx = require('rx-lite');
+```
+
+### In a Browser:
+
+```html
+<!-- Just the core RxJS -->
+<script src="path/to/rx.lite.js"></script>
+```

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install --save semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).

+set blocking `stdio` and `stderr` ensuring that terminal output does not truncate.
+
+```js
+const setBlocking = require('set-blocking')
+setBlocking(true)
+console.log(someLargeStringToOutput)
+```
+
+## Historical Context/Word of Warning
+
+This was created as a shim to address the bug discussed in [node #6456](https://github.com/nodejs/node/issues/6456). This bug crops up on
+newer versions of Node.js (`0.12+`), truncating terminal output.
+
+You should be mindful of the side-effects caused by using `set-blocking`:
+
+* if your module sets blocking to `true`, it will effect other modules
+  consuming your library. In [yargs](https://github.com/yargs/yargs/blob/master/yargs.js#L653) we only call
+  `setBlocking(true)` once we already know we are about to call `process.exit(code)`.
+* this patch will not apply to subprocesses spawned with `isTTY = true`, this is
+  the [default `spawn()` behavior](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).

+
+> Create nested getter properties and any intermediary dot notation (`'a.b.c'`) paths
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install set-getter --save
+```
+
+## Usage
+
+```js
+var getter = require('set-getter');
+```
+
+set-getter works like [set-value](https://github.com/jonschlinkert/set-value) by adding a property to an object or an object hierarchy using dot notation. The main difference is that the property is added using `Object.defineProperty` and is expected to be a getter function that returns a value.
+
+**Example**
+
+```js
+var obj = {};
+
+// root level property
+getter(obj, 'foo', function() {
+  return 'bar';
+});
+console.log(obj.foo);
+//=> 'bar'
+
+// property dot notation
+getter(obj, 'bar.baz', function() {
+  return 'qux';
+});
+console.log(obj.bar.baz);
+//=> 'qux'
+
+// property array notation
+getter(obj, ['beep', 'boop'], function() {
+  return 'bop';
+});
+console.log(obj.beep.boop);
+//=> 'bop'
+```
+
+## API
+
+### [setGetter](index.js#L27)
+
+Defines a getter function on an object using property path notation.
+
+**Params**
+
+* `obj` **{Object}**: Object to add property to.
+* `prop` **{String|Array}**: Property string or array to add.
+* `getter` **{Function}**: Getter function to add as a property.
+
+**Example**
+
+```js
+var obj = {};
+getter(obj, 'foo', function() {
+  return 'bar';
+});
+```
+

+# to-object-path [![NPM version](https://badge.fury.io/js/to-object-path.svg)](http://badge.fury.io/js/to-object-path)
+
+> Create an object path from a list or array of strings.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i to-object-path --save
+```
+
+## Usage
+
+```js
+var toPath = require('to-object-path');
+
+toPath('foo', 'bar', 'baz');
+toPath('foo', ['bar', 'baz']);
+//=> 'foo.bar.baz'
+```
+
+Also supports passing an arguments object (without having to slice args):
+
+```js
+function foo()
+  return toPath(arguments);
+}
+
+foo('foo', 'bar', 'baz');
+foo('foo', ['bar', 'baz']);
+//=> 'foo.bar.baz'
+```
+
+Visit the [example](./example.js) to see how this could be used in an application.

+# shallow-clone [![NPM version](https://badge.fury.io/js/shallow-clone.svg)](http://badge.fury.io/js/shallow-clone)
+
+> Make a shallow clone of an object, array or primitive.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i shallow-clone --save
+```
+
+## Usage
+
+```js
+var clone = require('shallow-clone');
+```
+
+## shallow clones arrays
+
+The array itself is cloned, but not the elements of the array. So any objects in the array will still not be cloned (e.g. they will be the same object as in the orginal array).
+
+```js
+var arr = [{ 'a': 0 }, { 'b': 1 }]
+var foo = clone(arr);
+// foo =>  [{ 'a': 0 }, { 'b': 1 }]
+
+// array is cloned
+assert.equal(actual === expected, false);
+
+// array elements are not
+assert.deepEqual(actual[0], expected[0]); // true
+```
+
+## returns primitives as-is
+
+```js
+clone(0)
+//=> 0
+
+clone('foo')
+//=> 'foo'
+```
+
+## shallow clone a regex
+
+```js
+clone(/foo/g)
+//=> /foo/g
+```
+
+## shallow clone an object
+
+```js
+clone({a: 1, b: 2, c: 3 })
+//=> {a: 1, b: 2, c: 3 }
+```

+* [is-number](https://github.com/jonschlinkert/is-number): Returns true if the value is a number. comprehensive tests.
+* [isobject](https://github.com/jonschlinkert/isobject): Returns true if the value is an object and not an array or null.
+* [is-primitive](https://github.com/jonschlinkert/is-primitive): Returns `true` if the value is a primitive.

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+> Split a string on a character except when the character is escaped.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save split-string
+```
+
+<!-- section: Why use this? -->
+
+<details>
+<summary><strong>Why use this?</strong></summary>
+
+<br>
+
+Although it's easy to split on a string:
+
+```js
+console.log('a.b.c'.split('.'));
+//=> ['a', 'b', 'c']
+```
+
+It's more challenging to split a string whilst respecting escaped or quoted characters.
+
+**Bad**
+
+```js
+console.log('a\\.b.c'.split('.'));
+//=> ['a\\', 'b', 'c']
+
+console.log('"a.b.c".d'.split('.'));
+//=> ['"a', 'b', 'c"', 'd']
+```
+
+**Good**
+
+```js
+var split = require('split-string');
+console.log(split('a\\.b.c'));
+//=> ['a.b', 'c']
+
+console.log(split('"a.b.c".d'));
+//=> ['a.b.c', 'd']
+```
+
+See the [options](#options) to learn how to choose the separator or retain quotes or escaping.
+
+<br>
+
+</details>
+
+## Usage
+
+```js
+var split = require('split-string');
+
+split('a.b.c');
+//=> ['a', 'b', 'c']
+
+// respects escaped characters
+split('a.b.c\\.d');
+//=> ['a', 'b', 'c.d']
+
+// respects double-quoted strings
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+```
+
+**Brackets**
+
+Also respects brackets [unless disabled](#optionsbrackets):
+
+```js
+split('a (b c d) e', ' ');
+//=> ['a', '(b c d)', 'e']
+```
+
+## Options
+
+### options.brackets
+
+**Type**: `object|boolean`
+
+**Default**: `undefined`
+
+**Description**
+
+If enabled, split-string will not split inside brackets. The following brackets types are supported when `options.brackets` is `true`,
+
+```js
+{
+  '<': '>',
+  '(': ')',
+  '[': ']',
+  '{': '}'
+}
+```
+
+Or, if object of brackets must be passed, each property on the object must be a bracket type, where the property key is the opening delimiter and property value is the closing delimiter.
+
+**Examples**
+
+```js
+// no bracket support by default
+split('a.{b.c}');
+//=> [ 'a', '{b', 'c}' ]
+
+// support all basic bracket types: "<>{}[]()"
+split('a.{b.c}', {brackets: true});
+//=> [ 'a', '{b.c}' ]
+
+// also supports nested brackets 
+split('a.{b.{c.d}.e}.f', {brackets: true});
+//=> [ 'a', '{b.{c.d}.e}', 'f' ]
+
+// support only the specified brackets
+split('[a.b].(c.d)', {brackets: {'[': ']'}});
+//=> [ '[a.b]', '(c', 'd)' ]
+```
+
+### options.sep
+
+**Type**: `string`
+
+**Default**: `.`
+
+The separator/character to split on.
+
+**Example**
+
+```js
+split('a.b,c', {sep: ','});
+//=> ['a.b', 'c']
+
+// you can also pass the separator as string as the last argument
+split('a.b,c', ',');
+//=> ['a.b', 'c']
+```
+
+### options.keepEscaping
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep backslashes in the result.
+
+**Example**
+
+```js
+split('a.b\\.c');
+//=> ['a', 'b.c']
+
+split('a.b.\\c', {keepEscaping: true});
+//=> ['a', 'b\.c']
+```
+
+### options.keepQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep single- or double-quotes in the result.
+
+**Example**
+
+```js
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a."b.c.d".e', {keepQuotes: true});
+//=> ['a', '"b.c.d"', 'e']
+
+split('a.\'b.c.d\'.e', {keepQuotes: true});
+//=> ['a', '\'b.c.d\'', 'e']
+```
+
+### options.keepDoubleQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep double-quotes in the result.
+
+**Example**
+
+```js
+split('a."b.c.d".e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a."b.c.d".e', {keepDoubleQuotes: true});
+//=> ['a', '"b.c.d"', 'e']
+```
+
+### options.keepSingleQuotes
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+Keep single-quotes in the result.
+
+**Example**
+
+```js
+split('a.\'b.c.d\'.e');
+//=> ['a', 'b.c.d', 'e']
+
+split('a.\'b.c.d\'.e', {keepSingleQuotes: true});
+//=> ['a', '\'b.c.d\'', 'e']
+```
+
+## Customizer
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Pass a function as the last argument to customize how tokens are added to the array.
+
+**Example**
+
+```js
+var arr = split('a.b', function(tok) {
+  if (tok.arr[tok.arr.length - 1] === 'a') {
+    tok.split = false;
+  }
+});
+console.log(arr);
+//=> ['a.b']
+```
+
+**Properties**
+
+The `tok` object has the following properties:
+
+* `tok.val` (string) The current value about to be pushed onto the result array
+* `tok.idx` (number) the current index in the string
+* `tok.str` (string) the entire string
+* `tok.arr` (array) the result array
+
+## Release history
+
+### v3.0.0 - 2017-06-17
+
+**Added**
+
+* adds support for brackets

+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable

+# sprintf.js
+**sprintf.js** is a complete open source JavaScript sprintf implementation for the *browser* and *node.js*.
+
+Its prototype is simple:
+
+    string sprintf(string format , [mixed arg1 [, mixed arg2 [ ,...]]])
+
+The placeholders in the format string are marked by `%` and are followed by one or more of these elements, in this order:
+
+* An optional number followed by a `$` sign that selects which argument index to use for the value. If not specified, arguments will be placed in the same order as the placeholders in the input string.
+* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers.
+* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*.
+* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result.
+* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded. When used with the `j` (JSON) type specifier, the padding length specifies the tab size used for indentation.
+* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used with the `g` type specifier, it specifies the number of significant digits. When used on a string, it causes the result to be truncated.
+* A type specifier that can be any of:
+    * `%` — yields a literal `%` character
+    * `b` — yields an integer as a binary number
+    * `c` — yields an integer as the character with that ASCII value
+    * `d` or `i` — yields an integer as a signed decimal number
+    * `e` — yields a float using scientific notation
+    * `u` — yields an integer as an unsigned decimal number
+    * `f` — yields a float as is; see notes on precision above
+    * `g` — yields a float as is; see notes on precision above
+    * `o` — yields an integer as an octal number
+    * `s` — yields a string as is
+    * `x` — yields an integer as a hexadecimal number (lower-case)
+    * `X` — yields an integer as a hexadecimal number (upper-case)
+    * `j` — yields a JavaScript object or array as a JSON encoded string
+
+## JavaScript `vsprintf`
+`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments:
+
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])
+
+## Argument swapping
+You can also swap the arguments. That is, the order of the placeholders doesn't have to match the order of the arguments. You can do that by simply indicating in the format string which arguments the placeholders refer to:
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+And, of course, you can repeat the placeholders without having to increase the number of arguments.
+
+## Named arguments
+Format strings may contain replacement fields rather than positional placeholders. Instead of referring to a certain argument, you can now refer to a certain key within an object. Replacement fields are surrounded by rounded parentheses - `(` and `)` - and begin with a keyword that refers to a key:
+
+    var user = {
+        name: "Dolly"
+    }
+    sprintf("Hello %(name)s", user) // Hello Dolly
+Keywords in replacement fields can be optionally followed by any number of keywords or indexes:
+
+    var users = [
+        {name: "Dolly"},
+        {name: "Molly"},
+        {name: "Polly"}
+    ]
+    sprintf("Hello %(users[0].name)s, %(users[1].name)s and %(users[2].name)s", {users: users}) // Hello Dolly, Molly and Polly
+Note: mixing positional and named placeholders is not (yet) supported
+
+## Computed values
+You can pass in a function as a dynamic value and it will be invoked (with no arguments) in order to compute the value on-the-fly.
+
+    sprintf("Current timestamp: %d", Date.now) // Current timestamp: 1398005382890
+    sprintf("Current date and time: %s", function() { return new Date().toString() })
+
+# AngularJS
+You can now use `sprintf` and `vsprintf` (also aliased as `fmt` and `vfmt` respectively) in your AngularJS projects. See `demo/`.
+
+# Installation
+
+## Via Bower
+
+    bower install sprintf
+
+## Or as a node.js module
+
+    npm install sprintf-js
+
+### Usage
+
+    var sprintf = require("sprintf-js").sprintf,
+        vsprintf = require("sprintf-js").vsprintf
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])

+# src-stream [![NPM version](https://badge.fury.io/js/src-stream.svg)](http://badge.fury.io/js/src-stream)  [![Build Status](https://travis-ci.org/doowb/src-stream.svg)](https://travis-ci.org/doowb/src-stream)
+
+> Wrap readable streams to turn them into passthrough streams.
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i src-stream --save
+```
+
+## Usage
+
+```js
+var src = require('src-stream');
+```
+
+## API
+
+### [srcStream](index.js#L39)
+
+Wrap a source stream to passthrough any data that's being written to it.
+
+**Params**
+
+* `stream` **{Stream}**: Readable stream to be wrapped.
+* `returns` **{Stream}**: Duplex stream to handle reading and writing.
+
+**Example**
+
+```js
+var src = require('src-stream');
+
+// wrap something that returns a readable stream
+var stream = src(plugin());
+
+fs.createReadStream('./package.json')
+  .pipe(stream)
+  .on('data', console.log)
+  .on('end', function () {
+    console.log();
+    console.log('Finished');
+    console.log();
+  });
+```

+
+Merge (interleave) a bunch of streams.
+
+[![build status](https://secure.travis-ci.org/grncdr/merge-stream.svg?branch=master)](http://travis-ci.org/grncdr/merge-stream)

+## Synopsis
+
+```javascript
+var stream1 = new Stream();
+var stream2 = new Stream();
+
+var merged = mergeStream(stream1, stream2);
+
+var stream3 = new Stream();
+merged.add(stream3);
+```
+
+## Description
+
+This is the merge function from [event-stream](https://github.com/dominictarr/event-stream) separated into a new module and given an `add` method so you can dynamically add more sources to the stream.

+# through2
+
+[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
+
+**A tiny wrapper around Node streams.Transform (Streams2) to avoid explicit subclassing noise**
+
+Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
+
+Note: A **Streams3** version of through2 is available in npm with the tag `"1.0"` rather than `"latest"` so an `npm install through2` will get you the current Streams2 version (version number is 0.x.x). To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
+
+```js
+fs.createReadStream('ex.txt')
+  .pipe(through2(function (chunk, enc, callback) {
+    for (var i = 0; i < chunk.length; i++)
+      if (chunk[i] == 97)
+        chunk[i] = 122 // swap 'a' for 'z'
+
+    this.push(chunk)
+
+    callback()
+   }))
+  .pipe(fs.createWriteStream('out.txt'))
+```
+
+Or object streams:
+
+```js
+var all = []
+
+fs.createReadStream('data.csv')
+  .pipe(csv2())
+  .pipe(through2.obj(function (chunk, enc, callback) {
+    var data = {
+        name    : chunk[0]
+      , address : chunk[3]
+      , phone   : chunk[10]
+    }
+    this.push(data)
+
+    callback()
+  }))
+  .on('data', function (data) {
+    all.push(data)
+  })
+  .on('end', function () {
+    doSomethingSpecial(all)
+  })
+```
+
+Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
+
+## API
+
+<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
+
+Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
+
+### options
+
+The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
+
+The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2({ objectMode: true, allowHalfOpen: false },
+    function (chunk, enc, cb) {
+      cb(null, 'wut?') // note we can use the second argument on the callback
+                       // to provide data as an alternative to this.push('wut?')
+    }
+  )
+  .pipe(fs.createWriteStream('/tmp/wut.txt'))
+```
+
+### transformFunction
+
+The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
+
+To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
+
+Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
+
+If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
+
+### flushFunction
+
+The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2(
+    function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop
+    function (cb) { // flush function
+      this.push('tacking on an extra buffer to the end');
+      cb();
+    }
+  ))
+  .pipe(fs.createWriteStream('/tmp/wut.txt'));
+```
+
+<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
+
+Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
+
+```js
+var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
+  if (record.temp != null && record.unit = "F") {
+    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
+    record.unit = "C"
+  }
+  this.push(record)
+  callback()
+})
+
+// Create instances of FToC like so:
+var converter = new FToC()
+// Or:
+var converter = FToC()
+// Or specify/override options when you instantiate, if you prefer:
+var converter = FToC({objectMode: true})
+```

+***Node-core streams for userland***

+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+
+## Combine (stream1,...,streamN)
+
+Turn a pipeline into a single stream. `Combine` returns a stream that writes to the first stream
+and reads from the last stream. 
+
+Listening for 'error' will recieve errors from all streams inside the pipe.
+
+```js
+var Combine = require('stream-combiner')
+var es      = require('event-stream')
+
+Combine(                                  // connect streams together with `pipe`
+  process.openStdin(),                    // open stdin
+  es.split(),                             // split stream to break on newlines
+  es.map(function (data, callback) {      // turn this async function into a stream
+    var repr = util.inspect(JSON.parse(data))  // render it nicely
+    callback(null, repr)
+  }),
+  process.stdout                          // pipe it to stdout !
+)
+```
+
+Can also be called with an array:
+
+```js
+var combinedStream = Combine([
+  stream1,
+  stream2,
+]);
+```
+
+Or to combine gulp plugins:
+
+```js
+function coffeePipe() {
+  return Combine(
+    coffeescript(),
+    coffeelint.reporter('fail').on('error', function(){
+      gutil.beep()
+      gulp.run('lint')
+    })
+}
+
+//usage:
+gulp.src().pipe(coffeePipe());
+```

+# stream-exhaust
+
+Ensure that the provided stream is flowing data, even if the stream hasn't been
+piped to another stream.
+
+```javascript
+var exhaustively = require('stream-exhaust');
+
+exhaustively(fs.createReadStream(__filename))
+  .on('close', () => { console.log('all done, despite being streams{1+N}!') });
+```
+
+## Prior Art
+
+This is based on [stream-consume](https://github.com/aroneous/stream-consume)
+by [aroneous](https://github.com/aroneous). It is a separate package because it has
+different semantics:
+
+1. It does not call `.resume()` on streams2+ streams. streams2 streams monkeypatch `.pipe`
+when entering flowing mode; avoiding `resume()` avoids that fate.
+2. It does not examine `._readableState`; instead it checks for the presence of `._read`.
+
+## API
+
+### exhaust(Stream s) -> Stream s
+
+Takes a stream, `s`, and returns it. Ensures that the stream is flowing, either by calling
+`.resume()` if the stream is a streams1 stream, or by piping it to a "black hole" stream that
+continually asks for more data.

+
+***Node-core v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+$ npm i stringify-author --save
+```
+
+## Usage
+
+```js
+var stringify = require('stringify-author');
+
+var authors = stringify({
+  name: 'Jon Schlinkert',
+  email: 'jon.schlinkert@sellside.com',
+  url: 'https://github.com/jonschlinkert'
+});
+
+console.log(authors);
+//=> 'Jon Schlinkert <jon.schlinkert@sellside.com> (https://github.com/jonschlinkert)'
+```
+
+Any of the properties can be used or missing:
+
+```js
+var authors = [
+  {name: 'Brian Woodward', url: 'https://github.com/doowb'},
+  {name: 'Jon Schlinkert', url: 'https://github.com/jonschlinkert'}

+
+> Strip UTF-8 [byte order mark](http://en.wikipedia.org/wiki/Byte_order_mark#UTF-8) (BOM) from a stream
+
+From Wikipedia:
+
+> The Unicode Standard permits the BOM in UTF-8, but does not require nor recommend its use. Byte order has no meaning in UTF-8.
+
+
+## Install
+
+```
+$ npm install --save strip-bom-stream
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var stripBomStream = require('strip-bom-stream');
+
+fs.createReadStream('unicorn.txt')
+	.pipe(stripBomStream())
+	.pipe(fs.createWriteStream('unicorn.txt'));
+```
+
+It's a [Transform stream](http://nodejs.org/api/stream.html#stream_class_stream_transform).

+# strip-bom [![Build Status](https://travis-ci.org/sindresorhus/strip-bom.svg?branch=master)](https://travis-ci.org/sindresorhus/strip-bom)
+
+> Strip UTF-8 [byte order mark](http://en.wikipedia.org/wiki/Byte_order_mark#UTF-8) (BOM) from a string/buffer
+
+From Wikipedia:
+
+> The Unicode Standard permits the BOM in UTF-8, but does not require nor recommend its use. Byte order has no meaning in UTF-8.
+
+
+## Install
+
+```
+$ npm install --save strip-bom
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var stripBom = require('strip-bom');
+
+stripBom('\uFEFFunicorn');
+//=> 'unicorn'
+
+stripBom(fs.readFileSync('unicorn.txt'));
+//=> 'unicorn'

+# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install --save supports-color
+```
+
+
+## Usage
+
+```js
+var supportsColor = require('supports-color');
+
+if (supportsColor) {
+	console.log('Terminal supports color');
+}
+```
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.

+
+> Tableize an object by flattening its keys into object paths (dot-notation).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install tableize-object --save
+```
+
+This is a simplified version of [tableize](https://github.com/segmentio/tableize), which also lower-cases keys and replaces spaces and dashes in keys with underscores. This library doesn't modify keys.
+
+## Usage
+
+```js
+var tableize = require('tableize-object');
+
+var obj = {
+  foo: {
+    bar: {
+      baz: 'qux',
+      fez: 'foo'
+    },
+    a: 'b',
+    c: 'b',
+    d: 'b',
+  }
+};
+
+console.log(tableize(obj));
+// results in:
+//{ 'foo.bar.baz': 'qux',
+//  'foo.bar.fez': 'foo',
+//  'foo.a': 'b',
+//  'foo.c': 'b',
+//  'foo.d': 'b' }
+```

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+* pagination
+* Much more!
+
+## Usage
+
+```js
+var templates = require('templates');
+var app = templates();
+```
+
+### Example
+
+```js
+// register an engine to automatically render `md` files
+app.engine('md', require('engine-lodash'));
+
+// create a template collection
+app.create('pages');
+
+// add a template to the collection
+app.page('post.md', {content: 'This is the <%= title %> page'});
+
+// render it
+app.render('post.md', {title: 'Home'}, function(err, view) {
+  console.log(view.content);
+  //=> 'This is the Home page'
+});
+```
+
+## API
+
+### Common
+
+This section describes API features that are shared by all Templates classes.
+
+#### .option
+
+Set or get an option value.
+
+**Params**
+
+* `key` **{String|Object}**: Pass a key-value pair or an object to set.
+* `val` **{any}**: Any value when a key-value pair is passed. This can also be options if a glob pattern is passed as the first value.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+app.option('a', 'b');
+app.option({c: 'd'});
+console.log(app.options);
+//=> {a: 'b', c: 'd'}
+```
+
+#### .use
+
+Run a plugin on the given instance. Plugins are invoked immediately upon instantiating in the order in which they were defined.
+
+**Example**
+
+The simplest plugin looks something like the following:
+
+```js
+app.use(function(inst) {
+  // do something to `inst`
+});
+```
+
+Note that `inst` is the instance of the class you're instantiating. So if you create an instance of `Collection`, inst is the collection instance.
+
+**Params**
+
+* `fn` **{Function}**: Plugin function. If the plugin returns a function it will be passed to the `use` method of each item created on the instance.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Usage**
+
+```js
+collection.use(function(items) {
+  // `items` is the instance, as is `this`
+
+  // optionally return a function to be passed to
+  // the `.use` method of each item created on the
+  // instance
+  return function(item) {
+    // do stuff to each `item`
+  };
+});
+```
+
+### App
+
+The `Templates` class is the main export of the `templates` library. All of the other classes are exposed as static properties on `Templates`:
+
+* [Item](#Item): Collection item, powered by [vinyl-item](https://github.com/jonschlinkert/vinyl-item).
+* [View](#View): Collection item, powered by [vinyl-view](https://github.com/jonschlinkert/vinyl-view).
+* [List](#List)
+* [Views](#Views):
+* [Collection](#Collection): Base collections class. Use this if you need to customize the render cycle, middleware stages, and so on.
+* [Group](#Group)
+
+### [Templates](index.js#L36)
+
+This function is the main export of the templates module. Initialize an instance of `templates` to create your application.
+
+**Params**
+
+* `options` **{Object}**
+
+**Example**
+
+```js
+var templates = require('templates');
+var app = templates();
+```
+
+### [.list](index.js#L154)
+
+Create a new list. See the [list docs](docs/lists.md) for more information about lists.
+
+**Params**
+
+* `opts` **{Object}**: List options
+* `returns` **{Object}**: Returns the `list` instance for chaining.
+
+**Example**
+
+```js
+var list = app.list();
+list.addItem('abc', {content: '...'});
+
+// or, create list from a collection
+app.create('pages');
+var list = app.list(app.pages);
+```
+
+### [.collection](index.js#L193)
+
+Create a new collection. Collections are decorated with special methods for getting and setting items from the collection. Note that, unlike the [create](#create) method, collections created with `.collection()` are not cached.
+
+See the [collection docs](docs/collections.md) for more
+information about collections.
+
+**Params**
+
+* `opts` **{Object}**: Collection options
+* `returns` **{Object}**: Returns the `collection` instance for chaining.
+
+### [.create](index.js#L245)
+
+Create a new view collection to be stored on the `app.views` object. See
+the [create docs](docs/collections.md#create) for more details.
+
+**Params**
+
+* `name` **{String}**: The name of the collection to create. Plural or singular form may be used, as the inflections are automatically resolved when the collection is created.
+* `opts` **{Object}**: Collection options
+* `returns` **{Object}**: Returns the `collection` instance for chaining.
+
+### [.setup](index.js#L375)
+
+Expose static `setup` method for providing access to an instance before any other code is run.
+
+**Params**
+
+* `app` **{Object}**: Application instance
+* `name` **{String}**: Optionally pass the constructor name to use.
+* `returns` **{undefined}**
+
+**Example**
+
+```js
+function App(options) {
+  Templates.call(this, options);
+  Templates.setup(this);
+}
+Templates.extend(App);
+```

+
+## History
+
+### v0.24.0
+
+* Bumps [base-data](https://github.com/node-base/base-data) which removed `renameKey` option used when loading data. Use the `namespace` option instead.
+
+### v0.23.0
+
+* Bumps [base-engine][] to fix a bug in [engine-cache](https://github.com/jonschlinkert/engine-cache).
+
+### v0.22.2
+
+* fixes `List` bug that was caused collection helpers to explode
+
+### v0.22.0
+
+There should be no breaking changes in this release. If you experience a regression, please [create an issue](../../issues).
+
+* Externalizes a few core plugins to: [base-helpers](https://github.com/node-base/base-helpers), [base-routes](https://github.com/node-base/base-routes), and [base-engine][]. The goal is to allow you to use only the plugins you need in your builds.
+* Improvements to lookup functions: `app.getView()` and `app.find()`
+* Bumps [base](https://github.com/node-base/base) to take advantages of code optimizations.
+
+### v0.21.0
+
+**Breaking changes**
+
+* The `queue` property has been removed, as well as related code for loading views using events. This behavior can easily be added using plugins or existing emitters.
+
+**Non-breaking**
+
+* The `View` and `Item` class have been externalized to modules [vinyl-item](https://github.com/jonschlinkert/vinyl-item) and [vinyl-view](https://github.com/jonschlinkert/vinyl-view) so they can be used in other libraries.
+
+### v0.20.0
+
+* **Context**: In general, context should be merged so that the most specific context wins over less specific. This fixes one case where locals was winning over front-matter
+* **Helpers**: Exposes `.ctx()` method on helper context, to simplify merging context in non-built-in helpers
+* **Engines**: Fixes bug that was using default engine on options instead of engine that matches view file extension.
+
+### v0.19.0
+
+* Numerous [dependency updates](https://github.com/jonschlinkert/templates/commit/6f78d88aa1920b84d20177bf35942e596b8e58b5)
+
+### v0.18.0
+
+* [Fixes inheritance bug](https://github.com/jonschlinkert/templates/commit/66b0d885648600c97b4a158eaebf3e95443ec66e) that only manifests in node v0.4.0
+* Improved [error handling in routes](https://github.com/jonschlinkert/templates/commit/d7654b74502465587da1e490c09e486fbf43f6db)
+
+### v0.17.0
+
+* Removed `debug` methods and related code
+* Improve layout handling with respect to template types (`partial`, `renderable` and `layout`)
+* Update dependencies
+
+### v0.16.0
+
+* Improved context handling
+* Ensure collection middleware is handled [after app middleware](https://github.com/jonschlinkert/templates/commit/f47385f5172a2773c3ab2a969ebfccc533ec5e27)
+
+### v0.15.0
+
+* removes `.removeItem` method that was deprecated in v0.10.7 from `List`
+* `.handleView` is deprecated in favor of `.handleOnce` and will be removed in a future version. Start using `.handleOnce` now.
+* adds a static `Templates.setup()` method for initializing any setup code that should have access to the instance before any other use code is run.
+* upgrade to [base-data](https://github.com/node-base/base-data) v0.4.0, which adds `app.option.set`, `app.option.get` and `app.option.merge`
+
+### v0.14.0
+
+Although 99% of users won't be effected by the changes in this release, there were some **potentially breaking changes**.
+
+* The `render` and `compile` methods were streamlined, making it clear that `.mergePartials` should not have been renamed to `mergePartialsSync`. So that change was reverted.
+* Helper context: Exposes a `this.helper` object to the context in helpers, which has the helper name and options that were set specifically for that helper
+* Helper context: Exposes a `this.view` object to the context in helpers, which is the current view being rendered. This was (and still is) always expose on `this.context.view`, but it makes sense to add this to the root of the context as a convenience. We will deprecate `this.context.view` in a future version.
+* Helper context: `.get`, `.set` and `.merge` methods on `this.options`, `this.context` and the `this` object in helpers.
+
+### v0.13.0
+
+* All template handling is async by default. Instead of adding `.compileSync`, we felt that it made more sense to add `.compileAsync`, since `.compile` is a public method and most users will expect it to be sync, and `.compile` methods with most engines are typically sync. In other words, `.compileAsync` probably won't be seen by most users, but we wanted to explain the decision to go against node.js naming conventions.
+* Improved layout detection and handling
+
+### v0.12.0
+
+* Adds helper methods, [.hasAsyncHelper](#hasasynchelper), [.hasHelper](#hashelper), [.getAsyncHelper](#getasynchelper), and [.getHelper](#gethelper)
+* Ensures that both collection and app routes are handled when both are defined for a view
+
+### v0.11.0
+
+* Default `engine` can now be defined on `app` or a collection using using `app.option('engine')`, `views.option('engine')`
+* Default `layout` can now defined using `app.option('layout')`, `views.option('layout')`. No changes have been made to `view.layout`, it should work as before. Resolves [issue/#818](../../issues/818)
+* Improves logic for finding a layout, this should make layouts easier to define and find going forward.
+* The built-in `view` helper has been refactored completely. The helper is now async and renders the view before returning its content.
+* Adds `isApp`, `isViews`, `isCollection`, `isList`, `isView`, `isGroup`, and `isItem` static methods. All return true when the given value is an instance of the respective class.
+* Adds `deleteItem` method to List and Collection, and `deleteView` method to Views.
+* Last, the static `_.proto` property which is only exposed for unit tests was renamed to `_.plugin`.
+
+### v0.10.7
+
+* Force-update [base](https://github.com/node-base/base) to v0.6.4 to take advantage of `isRegistered` feature.
+
+### v0.10.6
+
+* Re-introduces fs logic to `getView`, now that the method has been refactored to be faster.
+
+### v0.10.0
+
+* `getView` method no longer automatically reads views from the file system. This was undocumented before and, but it's a breaking change nonetheless. The removed functionality can easily be done in a plugin.
+
+### v0.9.5
+
+* Fixes error messages when no engine is found for a view, and the view does not have a file extension.
+
+### v0.9.4
+
+* Fixes a lookup bug in render and compile that was returning the first view that matched the given name from _any_ collection. So if a partial and a page shared the same name, if the partial was matched first it was returned. Now the `renderable` view is rendered (e.g. page)
+
+### v0.9.0
+
+* _breaking change_: changes parameters on `app.context` method. It now only accepts two arguments, `view` and `locals`, since `ctx` (the parameter that was removed) was technically being merged in twice.
+
+### v0.8.0
+
+* Exposes `isType` method on `view`. Shouldn't be any breaking changes.
+
+### v0.7.0
+
+* _breaking change_: renamed `.error` method to `.formatError`
+* adds `mergeContext` option
+* collection name is now emitted with `view` and `item` as the second argument
+* adds `isType` method for checking the `viewType` on a collection
+* also now emits an event with the collection name when a view is created
+
+### v0.5.1
+
+* fixes bug where `default` layout was automatically applied to partials, causing an infinite loop in rare cases.

+### v0.24.0
+
+- Bumps [base-data][] which removed `renameKey` option used when loading data. Use the `namespace` option instead.
+
+### v0.23.0
+
+- Bumps [base-engine][] to fix a bug in [engine-cache][].
+
+### v0.22.2
+
+- fixes `List` bug that was caused collection helpers to explode
+
+### v0.22.0
+
+There should be no breaking changes in this release. If you experience a regression, please [create an issue](../../issues).
+
+- Externalizes a few core plugins to: [base-helpers][], [base-routes][], and [base-engine][]. The goal is to allow you to use only the plugins you need in your builds.
+- Improvements to lookup functions: `app.getView()` and `app.find()`
+- Bumps [base][] to take advantages of code optimizations.
+
+### v0.21.0
+
+**Breaking changes**
+
+- The `queue` property has been removed, as well as related code for loading views using events. This behavior can easily be added using plugins or existing emitters.
+
+**Non-breaking**
+
+- The `View` and `Item` class have been externalized to modules [vinyl-item][] and [vinyl-view][] so they can be used in other libraries.
+
+### v0.20.0
+
+- **Context**: In general, context should be merged so that the most specific context wins over less specific. This fixes one case where locals was winning over front-matter
+- **Helpers**: Exposes `.ctx()` method on helper context, to simplify merging context in non-built-in helpers
+- **Engines**: Fixes bug that was using default engine on options instead of engine that matches view file extension.
+
+### v0.19.0
+
+- Numerous [dependency updates](https://github.com/jonschlinkert/templates/commit/6f78d88aa1920b84d20177bf35942e596b8e58b5)
+
+### v0.18.0
+
+- [Fixes inheritance bug](https://github.com/jonschlinkert/templates/commit/66b0d885648600c97b4a158eaebf3e95443ec66e) that only manifests in node v0.4.0
+- Improved [error handling in routes](https://github.com/jonschlinkert/templates/commit/d7654b74502465587da1e490c09e486fbf43f6db)
+
+### v0.17.0
+
+- Removed `debug` methods and related code
+- Improve layout handling with respect to template types (`partial`, `renderable` and `layout`)
+- Update dependencies
+
+### v0.16.0
+
+- Improved context handling
+- Ensure collection middleware is handled [after app middleware](https://github.com/jonschlinkert/templates/commit/f47385f5172a2773c3ab2a969ebfccc533ec5e27)
+
+### v0.15.0
+
+- removes `.removeItem` method that was deprecated in v0.10.7 from `List`
+- `.handleView` is deprecated in favor of `.handleOnce` and will be removed in a future version. Start using `.handleOnce` now.
+- adds a static `Templates.setup()` method for initializing any setup code that should have access to the instance before any other use code is run.
+- upgrade to [base-data][] v0.4.0, which adds `app.option.set`, `app.option.get` and `app.option.merge`
+
+### v0.14.0
+
+Although 99% of users won't be effected by the changes in this release, there were some **potentially breaking changes**.
+
+- The `render` and `compile` methods were streamlined, making it clear that `.mergePartials` should not have been renamed to `mergePartialsSync`. So that change was reverted.
+- Helper context: Exposes a `this.helper` object to the context in helpers, which has the helper name and options that were set specifically for that helper
+- Helper context: Exposes a `this.view` object to the context in helpers, which is the current view being rendered. This was (and still is) always expose on `this.context.view`, but it makes sense to add this to the root of the context as a convenience. We will deprecate `this.context.view` in a future version.
+- Helper context: `.get`, `.set` and `.merge` methods on `this.options`, `this.context` and the `this` object in helpers.
+
+### v0.13.0
+

Instead of adding `.compileSync`, we felt that it made more sense to add `.compileAsync`, since `.compile` is a public method and most users will expect it to be sync, and `.compile` methods with most engines are typically sync.

+```
+
+## var s = table(rows, opts={})
+
+Return a formatted table string `s` from an array of `rows` and some options
+`opts`.
+
+`rows` should be an array of arrays containing strings, numbers, or other
+printable values.
+
+options can be:
+
+* `opts.hsep` - separator to use between columns, default `'  '`
+* `opts.align` - array of alignment types for each column, default `['l','l',...]`
+* `opts.stringLength` - callback function to use when calculating the string length
+
+alignment types are:
+
+* `'l'` - left
+* `'r'` - right
+* `'c'` - center
+* `'.'` - decimal
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install text-table
+```
+
+# Use with ANSI-colors
+
+Since the string length of ANSI color schemes does not equal the length
+JavaScript sees internally it is necessary to pass the a custom string length
+calculator during the main function call.
+
+See the `test/ansi-colors.js` file for an example.

+[![build status](https://secure.travis-ci.org/dominictarr/through.png)](http://travis-ci.org/dominictarr/through)
+[![testling badge](https://ci.testling.com/dominictarr/through.png)](https://ci.testling.com/dominictarr/through)
+
+Easy way to create a `Stream` that is both `readable` and `writable`. 
+
+* Pass in optional `write` and `end` methods.
+* `through` takes care of pause/resume logic if you use `this.queue(data)` instead of `this.emit('data', data)`.
+* Use `this.pause()` and `this.resume()` to manage flow.
+* Check `this.paused` to see current flow state. (`write` always returns `!this.paused`).
+
+This function is the basis for most of the synchronous streams in 
+[event-stream](http://github.com/dominictarr/event-stream).
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.queue(data) //data *must* not be null
+  },
+  function end () { //optional
+    this.queue(null)
+  })
+```
+
+Or, can also be used _without_ buffering on pause, use `this.emit('data', data)`,
+and this.emit('end')
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.emit('data', data)
+    //this.pause() 
+  },
+  function end () { //optional
+    this.emit('end')
+  })
+```
+
+## Extended Options
+
+You will probably not need these 99% of the time.
+
+### autoDestroy=false
+
+By default, `through` emits close when the writable
+and readable side of the stream has ended.
+If that is not desired, set `autoDestroy=false`.
+
+``` js
+var through = require('through')
+
+//like this
+var ts = through(write, end, {autoDestroy: false})
+//or like this
+var ts = through(write, end)
+ts.autoDestroy = false
+```

+through2-filter
+===============
+
+[![NPM](https://nodei.co/npm/through2-filter.png)](https://nodei.co/npm/through2-filter/)
+
+This is a super thin wrapper around [through2](http://npm.im/through2) that works like `Array.prototype.filter` but for streams.
+
+For when through2 is just too verbose :wink:
+
+Note you will **NOT** be able to alter the content of the chunks. This is intended for filtering only. If you want to modify the stream content, use either `through2` or `through2-map`.
+
+```js
+var filter = require("through2-filter")
+
+var skip = filter(function (chunk) {
+  // skip buffers longer than 100
+  return chunk.length < 100
+})
+
+// vs. with through2:
+var skip = through2(function (chunk, encoding, callback) {
+  // skip buffers longer than 100
+  if (chunk.length < 100) this.push(chunk)
+  return callback()
+})
+
+// Then use your filter:
+source.pipe(skip).pipe(sink)
+
+// Additionally accepts `wantStrings` argument to conver buffers into strings
+var alphanum = new RegExp("^[A-Za-z0-1]+$")
+var scrub = filter({wantStrings: true}, function (str) {
+  return alphanum.exec(str)
+})
+
+// Works like `Array.prototype.filter` meaning you can specify a function that
+// takes up to two* arguments: fn(element, index)
+var skip10 = filter(function (element, index) {
+  return index > 10
+})
+```
+
+*Differences from `Array.prototype.filter`:
+  * No third `array` callback argument. That would require realizing the entire stream, which is generally counter-productive to stream operations.
+  * `Array.prototype.filter` doesn't modify the source Array, which is somewhat nonsensical when applied to streams.
+
+API
+---
+
+`require("through2-filter")([options], fn)`
+---
+
+Create a `through2-filter` instance that will call `fn(chunk)`. If `fn(chunk)` returns "true" the chunk will be passed downstream. Otherwise it will be dropped.
+
+`require("through2-filter").ctor([options], fn)`
+---
+
+Create a `through2-filter` Type that can be instantiated via `new Type()` or `Type()` to create reusable spies.
+
+`require("through2-filter").obj([options], fn)`
+---
+
+Create a `through2-filter` that defaults to `objectMode = true`.
+
+`require("through2-filter").objCtor([options], fn)`
+---
+
+Create a `through2-filter` Type that defaults to `objectMode = true`.
+
+Options
+-------
+
+  * wantStrings: Automatically call chunk.toString() for the super lazy.
+  * all other through2 options

+# through2
+
+[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
+
+**A tiny wrapper around Node streams.Transform (Streams2/3) to avoid explicit subclassing noise**
+
+Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
+
+Note: As 2.x.x this module starts using **Streams3** instead of Stream2. To continue using a Streams2 version use `npm install through2@0` to fetch the latest version of 0.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
+
+```js
+fs.createReadStream('ex.txt')
+  .pipe(through2(function (chunk, enc, callback) {
+    for (var i = 0; i < chunk.length; i++)
+      if (chunk[i] == 97)
+        chunk[i] = 122 // swap 'a' for 'z'
+
+    this.push(chunk)
+
+    callback()
+   }))
+  .pipe(fs.createWriteStream('out.txt'))
+  .on('finish', () => doSomethingSpecial())
+```
+
+Or object streams:
+
+```js
+var all = []
+
+fs.createReadStream('data.csv')
+  .pipe(csv2())
+  .pipe(through2.obj(function (chunk, enc, callback) {
+    var data = {
+        name    : chunk[0]
+      , address : chunk[3]
+      , phone   : chunk[10]
+    }
+    this.push(data)
+
+    callback()
+  }))
+  .on('data', (data) => {
+    all.push(data)
+  })
+  .on('end', () => {
+    doSomethingSpecial(all)
+  })
+```
+
+Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
+
+## API
+
+<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
+
+Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
+
+### options
+
+The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
+
+The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2({ objectMode: true, allowHalfOpen: false },
+    (chunk, enc, cb) => {
+      cb(null, 'wut?') // note we can use the second argument on the callback
+                       // to provide data as an alternative to this.push('wut?')
+    }
+  )
+  .pipe(fs.createWriteStream('/tmp/wut.txt'))
+```
+
+### transformFunction
+
+The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
+
+To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
+
+Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
+
+If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
+
+### flushFunction
+
+The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2(
+    (chunk, enc, cb) => cb(null, chunk), // transform is a noop
+    function (cb) { // flush function
+      this.push('tacking on an extra buffer to the end');
+      cb();
+    }
+  ))
+  .pipe(fs.createWriteStream('/tmp/wut.txt'));
+```
+
+<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
+
+Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
+
+```js
+var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
+  if (record.temp != null && record.unit == "F") {
+    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
+    record.unit = "C"
+  }
+  this.push(record)
+  callback()
+})
+
+// Create instances of FToC like so:
+var converter = new FToC()
+// Or:
+var converter = FToC()
+// Or specify/override options when you instantiate, if you prefer:
+var converter = FToC({objectMode: true})
+```

+# time-diff [![NPM version](https://img.shields.io/npm/v/time-diff.svg?style=flat)](https://www.npmjs.com/package/time-diff) [![NPM downloads](https://img.shields.io/npm/dm/time-diff.svg?style=flat)](https://npmjs.org/package/time-diff) [![Build Status](https://img.shields.io/travis/jonschlinkert/time-diff.svg?style=flat)](https://travis-ci.org/jonschlinkert/time-diff)
+
+Returns the formatted, high-resolution time difference between `start` and `end` times.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install time-diff --save
+```
+
+## Usage
+
+Uses [pretty-time][] to format time diffs.
+
+```js
+var Time = require('time-diff');
+var time = new Time();
+
+// create a start time for `foo`
+time.start('foo');
+
+// call `end` wherever the `foo` process ends
+console.log(time.end('foo'));
+//=> 12ms
+```
+
+## API
+
+### [.start](index.js#L57)
+
+Start a timer for the given `name`.
+
+**Params**
+
+* `name` **{String}**: Name to use for the starting time.
+* `returns` **{Array}**: Returns the array from `process.hrtime()`
+
+**Example**
+
+```js
+var time = new Time();
+time.start('foo');
+```
+
+### [.end](index.js#L86)
+
+Returns the cumulative elapsed time since the **first time** `time.start(name)` was called.
+
+**Params**
+
+* `name` **{String}**: The name of the cached starting time to create the diff
+* `returns` **{Array}**: Returns the array from `process.hrtime()`
+
+**Example**
+
+```js
+var time = new Time();
+time.start('foo');
+
+// do stuff
+time.end('foo');
+//=> 104μs
+
+// do more stuff
+time.end('foo');
+//=> 1ms
+
+// do more stuff
+time.end('foo');
+//=> 2ms
+```
+
+### [.diff](index.js#L134)
+
+Returns a function for logging out out both the cumulative elapsed time since the first time `.diff(name)` was called, as well as the incremental elapsed time since the last `.diff(name)` was called. Unlike `.end()`, this method logs to `stderr` instead of returning a string. We could probably change this to return an object, feedback welcome.
+
+Results in something like:

+<img width="509" alt="screen shot 2016-04-13 at 7 45 12 pm" src="https://cloud.githubusercontent.com/assets/383994/14512800/478e1256-01b0-11e6-9e97-c6b625f097f7.png">
+
+**Params**
+
+* `name` **{String}**: The name of the starting time to store.
+* `options` **{String}**
+
+**Example**
+
+```js
+var time = new Time();
+var diff = time.diff('my-app-name');
+
+// do stuff
+diff('after init');
+//=> [19:44:05] my-app-name: after init 108μs
+
+// do more stuff
+diff('before options');
+//=> [19:44:05] my-app-name: before options 2ms (+2ms)
+
+// do more stuff
+diff('after options');
+//=> [19:44:05] my-app-name: after options 2ms (+152μs)
+```
+
+## Options
+
+### options.logDiff
+
+Disable time diffs, or filter time diffs to the specified name(s).
+
+**type**: `Boolean|String`
+
+**default**: `undefined`
+
+### options.nocolor
+
+Set to `true` to disable color in the output.
+
+**type**: `Boolean`
+
+**default**: `undefined`
+
+**Example**
+
+```js
+var diff = time.diff('foo', {nocolor: true});
+```
+
+### options.formatArgs
+
+Format arguments passed to `process.stderr`.
+
+**type**: `Function`
+
+**default**: `undefined`
+
+**Examples**
+
+Show `message` and `elapsed` time only:
+
+```js
+var time = new Time();
+var diff = time.diff('foo', {
+  formatArgs: function(timestamp, name, msg, elapsed) {
+    return [msg, elapsed];
+  }
+});
+
+diff('first diff');
+//=> 'first diff 36μs'
+diff('second diff');
+//=> 'second diff 71μs'
+```
+
+Show `name` and `elapsed` time only:
+
+```js
+var diff = time.diff('foo', {
+  formatArgs: function(timestamp, name, msg, elapsed) {
+    return [name, elapsed];
+  }
+});
+
+diff('first diff');
+//=> 'foo 36μs'
+diff('second diff');
+//=> 'foo 71μs'
+```
+
+## Examples
+
+Create an instance of `Time`, optionally specifying the time scale to use and the number of decimal places to display.
+
+**Options**
+
+* `options.smallest`: the smallest time scale to show
+* `options.digits`: the number of decimal places to display (`digits`)
+
+**Examples**
+
+_(See [pretty-time][] for all available formats)_
+
+Given the following:
+
+```js
+var time = new Time(options);
+time.start('foo');
+```
+
+Returns milliseconds by default
+
+```js
+console.log(time.end('foo'));
+//=> 13ms
+```
+
+Milliseconds to 3 decimal places
+
+```js
+console.log(time.end('foo', 'ms', 3));
+// or
+console.log(time.end('foo', 3));
+//=> 12.743ms
+```
+
+Seconds to 3 decimal places
+
+```js
+console.log(time.end('foo', 's', 3));
+//=> 0.013s
+```
+
+Seconds
+
+```js
+console.log(time.end('foo', 's'));
+//=> 0s
+```
+
+Microseconds
+
+```js
+console.log(time.end('foo', 'μs'));
+//=> 12ms 934μs
+```
+
+Microseconds to 2 decimal places
+
+```js
+console.log(time.end('foo', 'μs', 2));
+//=> 14ms 435.78μs
+```
+
+nano-seconds
+
+```js
+console.log(time.end('foo', 'n', 3));
+//=> 13ms 796μs 677ns
+```
+
+nano-seconds to 3 decimal places
+
+```js
+console.log(time.end('foo', 'n', 3));
+//=> 13ms 427μs 633.000ns
+```
+
+## CLI usage
+
+If you're using `time-diff` with a command line application, try using [minimist][] for setting options.
+
+```js
+var opts = {alias: {nocolor: 'n', logTime: 't', logDiff: 'd'}};
+var argv = require('minimist')(process.argv.slice(2), opts);
+
+var Time = require('time-diff');
+var time = new Time(argv);
+```

+# lazy-cache [![NPM version](https://img.shields.io/npm/v/lazy-cache.svg)](https://www.npmjs.com/package/lazy-cache) [![Build Status](https://img.shields.io/travis/jonschlinkert/lazy-cache.svg)](https://travis-ci.org/jonschlinkert/lazy-cache)
+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i lazy-cache --save
+```
+
+## Usage
+
+```js
+var lazy = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var lazy = require('lazy-cache')(require);
+
+// `npm install glob`
+lazy('glob');
+
+// glob sync
+console.log(lazy.glob.sync('*.js'));
+
+// glob async
+lazy.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var lazy = require('lazy-cache')(require);
+var glob = lazy('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases, it may be necessary to unlazy all lazy-cached dependencies (two reported cases out of > 9 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```

+
+```sh
+$ npm i -d && npm test
+```

+
+timestamp();
+//=> 2017:05:14
+
+timestamp('YYYYMMDD');
+//=> 20170514
+
+timestamp('YYYYMMDD:ss');
+//=> 20170514:26
+
+timestamp('YYYY/MM/DD:mm:ss');
+//=> 2017/05/14:52:26
+
+timestamp('YYYY:MM:DD');
+//=> 2017:05:14
+
+timestamp('[YYYY:MM:DD]');
+//=> [2017:05:14]
+
+timestamp('YYYY/MM/DD');
+//=> 2017/05/14
+
+timestamp('YYYY:MM');
+//=> 2017:05
+
+timestamp('YYYY');
+//=> 2017
+
+timestamp('MM');
+//=> 05
+
+timestamp('DD');
+//=> 14
+
+timestamp('HH');
+//=> 20
+
+timestamp('mm');

+
+> Make a glob pattern absolute, ensuring that negative globs and patterns with trailing slashes are correctly handled.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i to-absolute-glob --save
+```
+
+## Usage
+
+```js
+var toAbsGlob = require('to-absolute-glob');
+toAbsGlob('a/*.js');
+//=> '/dev/foo/a/*.js'
+```
+
+## Examples
+
+Given the current project folder (cwd) is `/dev/foo/`:
+
+**makes a path absolute**
+
+```js
+toAbsGlob('a');
+//=> '/dev/foo/a'
+```
+
+**makes a glob absolute**
+
+```js
+toAbsGlob('a/*.js');
+//=> '/dev/foo/a/*.js'
+```
+
+**retains trailing slashes**
+
+```js
+toAbsGlob('a/*/');
+//=> '/dev/foo/a/*/'
+```
+
+**retains trailing slashes with cwd**
+
+```js
+toAbsGlob('./fixtures/whatsgoingon/*/', {cwd: __dirname});
+//=> '/dev/foo/'
+```
+
+**makes a negative glob absolute**
+
+```js
+toAbsGlob('!a/*.js');
+//=> '!/dev/foo/a/*.js'
+```
+
+**from a cwd**
+
+```js
+toAbsGlob('a/*.js', {cwd: 'foo'});
+//=> '/dev/foo/foo/a/*.js'
+```
+
+**makes a negative glob absolute from a cwd**
+
+```js
+toAbsGlob('!a/*.js', {cwd: 'foo'});
+//=> '!/dev/foo/foo/a/*.js'
+```
+
+**from a root path**
+
+```js
+toAbsGlob('/a/*.js', {root: 'baz'});
+//=> '/dev/foo/baz/a/*.js'
+```
+
+**from a root slash**
+
+```js
+toAbsGlob('/a/*.js', {root: '/'});
+//=> '/dev/foo/a/*.js'
+```
+
+**from a negative root path**
+
+```js
+toAbsGlob('!/a/*.js', {root: 'baz'});
+//=> '!/dev/foo/baz/a/*.js'
+```
+
+**from a negative root slash**
+
+```js
+toAbsGlob('!/a/*.js', {root: '/'});
+//=> '!/dev/foo/a/*.js'
+```

+# to-choices [![NPM version](https://img.shields.io/npm/v/to-choices.svg)](https://www.npmjs.com/package/to-choices) [![Build Status](https://img.shields.io/travis/generate/to-choices.svg)](https://travis-ci.org/generate/to-choices)
+
+> Easily create a normalized inquirer choices question. Supports all of the `choices` question types: checkbox, list, rawlist, expand
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install to-choices --save
+```
+
+## Heads up!
+
+**Breaking changes made in v02.0!**
+
+The main export now returns a function that takes an options object and, when called, returns the `toChoices` function to be usef for creating the question object.
+
+## Usage
+
+```js
+var toChoices = require('to-choices')([options]);
+
+var question = toChoices('foo', ['a', 'b', 'c']);
+console.log(question);
+```
+
+The default `type` is `checkbox`, so the above code results in:
+
+```js
+{ type: 'checkbox',
+  name: 'foo',
+  message: 'foo',
+  choices:
+   [ { name: 'all', value: ['a', 'b', 'c'] },
+     { type: 'separator', line: '\u001b[90m————\u001b[39m' },
+     { name: 'a' },
+     { name: 'b' },
+     { name: 'c' } ] }
+```
+
+## Supported question types
+
+In addition to `checkbox`, the following types are also supported:
+
+* `expand`
+* `list`
+* `rawlist`
+
+Signature and all params are the same. Just pass the `type` to the main export.
+
+**Example**
+
+Create a `list` question:
+
+```js
+var toQuestions = require('to-choices')({type: 'list'});
+var question = toChoices('favorite color?', [
+  'red',
+  'blue',
+  'green'
+]);
+console.log(question);
+```
+
+Results in:
+
+```js
+{ type: 'list',
+  choices: [ 'red', 'blue', 'green' ],
+  name: 'favorite color',
+  message: 'favorite color' }
+```
+
+See the [inquirer2](https://github.com/jonschlinkert/inquirer2) documentation for more details about question objects and supported properties.

+
+Convert a file path to a vinyl file.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install to-file --save
+```
+
+## Usage
+
+```js
+var toFile = require('to-file');
+var glob = require('glob');
+
+var files = glob.sync('**/*.js')
+files = files.map(function(fp) {
+  return toFile(fp);
+});
+```
+
+**glob parent**
+
+Optionally pass the original glob pattern as the second argument to populate `file.base` from the [glob-parent](https://github.com/es128/glob-parent).
+
+```js
+var files = glob.sync('**/*.js')
+files = files.map(function(fp) {
+  return toFile(fp, '**/*.js');
+});
+```
+
+**options**
+
+If an options object is passed as the second or third argument, the `cwd` and `base` properties will be used to update the file object, and the `options` object will be added as a property on the `file` object.
+
+```js
+var files = glob.sync('**/*.js')
+files = files.map(function(fp) {
+  return toFile(fp, '**/*.js');
+});
+```

+# is-glob [![NPM version](https://badge.fury.io/js/is-glob.svg)](http://badge.fury.io/js/is-glob)  [![Build Status](https://travis-ci.org/jonschlinkert/is-glob.svg)](https://travis-ci.org/jonschlinkert/is-glob)
+
+> Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.
+
+Also take a look at [is-valid-glob](https://github.com/jonschlinkert/is-valid-glob) and [has-glob](https://github.com/jonschlinkert/has-glob).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i is-glob --save
+```
+
+## Usage
+
+```js
+var isGlob = require('is-glob');
+```
+
+**True**
+
+Patterns that have glob characters or regex patterns will return `true`:
+
+```js
+isGlob('!foo.js');
+isGlob('*.js');
+isGlob('**/abc.js');
+isGlob('abc/*.js');
+isGlob('abc/(aaa|bbb).js');
+isGlob('abc/[a-z].js');
+isGlob('abc/{a,b}.js');
+isGlob('abc/?.js');
+//=> true
+```
+
+Extglobs
+
+```js
+isGlob('abc/@(a).js');
+isGlob('abc/!(a).js');
+isGlob('abc/+(a).js');
+isGlob('abc/*(a).js');
+isGlob('abc/?(a).js');
+//=> true
+```
+
+**False**
+
+Patterns that do not have glob patterns return `false`:
+
+```js
+isGlob('abc.js');
+isGlob('abc/def/ghi.js');
+isGlob('foo.js');
+isGlob('abc/@.js');
+isGlob('abc/+.js');
+isGlob();
+isGlob(null);
+//=> false
+```
+
+Arrays are also `false` (If you want to check if an array has a glob pattern, use [has-glob](https://github.com/jonschlinkert/has-glob)):
+
+```js
+isGlob(['**/*.js']);
+isGlob(['foo.js']);
+//=> false
+```

+
+> Create an object path from a list or array of strings.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i to-object-path --save
+```
+
+## Usage
+
+```js
+var toPath = require('to-object-path');
+
+toPath('foo', 'bar', 'baz');
+toPath('foo', ['bar', 'baz']);
+//=> 'foo.bar.baz'
+```
+
+Also supports passing an arguments object (without having to slice args):
+
+```js
+function foo()
+  return toPath(arguments);
+}
+
+foo('foo', 'bar', 'baz');
+foo('foo', ['bar', 'baz']);
+//=> 'foo.bar.baz'
+```
+
+Visit the [example](./example.js) to see how this could be used in an application.

+## Benchmarks
+
+Benchmarked against [typeof](http://github.com/CodingFu/typeof) and [type-of](https://github.com/ForbesLindesay/type-of).
+Note that performaces is slower for es6 features `Map`, `WeakMap`, `Set` and `WeakSet`.

+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`

+
+> Regular expression for testing if a file path is a windows UNC file path. Can also be used as a component of another regexp via the `.source` property.
+
+Visit the MSDN reference for [Common Data Types 2.2.57 UNC](https://msdn.microsoft.com/en-us/library/gg465305.aspx) for more information about UNC paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i unc-path-regex --save
+```
+
+## Usage
+
+```js
+// unc-path-regex returns a function
+var regex = require('unc-path-regex')();
+```
+
+**true**
+
+Returns true for windows UNC paths:
+
+```js
+regex.test('\\/foo/bar');
+regex.test('\\\\foo/bar');
+regex.test('\\\\foo\\admin$');
+regex.test('\\\\foo\\admin$\\system32');
+regex.test('\\\\foo\\temp');
+regex.test('\\\\/foo/bar');
+regex.test('\\\\\\/foo/bar');
+```
+
+**false**
+
+Returns false for non-UNC paths:
+
+```js
+regex.test('/foo/bar');
+regex.test('/');
+regex.test('/foo');
+regex.test('/foo/');
+regex.test('c:');
+regex.test('c:.');
+regex.test('c:./');
+regex.test('c:./file');
+regex.test('c:/');
+regex.test('c:/file');
+```

+
+> Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save set-value
+```
+
+## Usage
+
+```js
+var set = require('set-value');
+set(object, prop, value);
+```
+
+### Params
+
+* `object` **{object}**: The object to set `value` on
+* `prop` **{string}**: The property to set. Dot-notation may be used.
+* `value` **{any}**: The value to set on `object[prop]`
+
+## Examples
+
+Updates and returns the given object:
+
+```js
+var obj = {};
+set(obj, 'a.b.c', 'd');
+console.log(obj);
+//=> { a: { b: { c: 'd' } } }
+```
+
+### Escaping
+
+**Escaping with backslashes**
+
+Prevent set-value from splitting on a dot by prefixing it with backslashes:
+
+```js
+console.log(set({}, 'a\\.b.c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, 'a\\.b\\.c', 'd'));
+//=> { 'a.b.c': 'd' }
+```
+
+**Escaping with double-quotes or single-quotes**
+
+Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:
+
+```js
+console.log(set({}, '"a.b".c', 'd'));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, "'a.b'.c", "d"));
+//=> { 'a.b': { c: 'd' } }
+
+console.log(set({}, '"this/is/a/.file.path"', 'd'));
+//=> { 'this/is/a/file.path': 'd' }
+```
+
+### Bracket support
+
+set-value does not split inside brackets or braces:
+
+```js
+console.log(set({}, '[a.b].c', 'd'));
+//=> { '[a.b]': { c: 'd' } }
+
+console.log(set({}, "(a.b).c", "d"));
+//=> { '(a.b)': { c: 'd' } }
+
+console.log(set({}, "<a.b>.c", "d"));
+//=> { '<a.b>': { c: 'd' } }
+
+console.log(set({}, "{a..b}.c", "d"));
+//=> { '{a..b}': { c: 'd' } }
+```
+
+## History
+
+### v2.0.0
+
+* Adds support for escaping with double or single quotes. See [escaping](#escaping) for examples.
+* Will no longer split inside brackets or braces. See [bracket support](#bracket-support) for examples.
+
+If there are any regressions please create a [bug report](../../issues/new). Thanks!

+# unique-stream
+
+node.js through stream that emits a unique stream of objects based on criteria
+
+[![Build Status](https://travis-ci.org/eugeneware/unique-stream.svg?branch=master)](https://travis-ci.org/eugeneware/unique-stream)
+[![Coverage Status](https://coveralls.io/repos/eugeneware/unique-stream/badge.svg?branch=master&service=github)](https://coveralls.io/github/eugeneware/unique-stream?branch=master)
+
+## Installation
+
+Install via [npm](https://www.npmjs.com/):
+
+```
+$ npm install unique-stream
+```
+
+## Examples
+
+### Dedupe a ReadStream based on JSON.stringify:
+
+``` js
+var unique = require('unique-stream')
+  , Stream = require('stream');
+
+// return a stream of 3 identical objects
+function makeStreamOfObjects() {
+  var s = new Stream;
+  s.readable = true;
+  var count = 3;
+  for (var i = 0; i < 3; i++) {
+    setImmediate(function () {
+      s.emit('data', { name: 'Bob', number: 123 });
+      --count || end();
+    });
+  }
+
+  function end() {
+    s.emit('end');
+  }
+
+  return s;
+}
+
+// Will only print out one object as the rest are dupes. (Uses JSON.stringify)
+makeStreamOfObjects()
+  .pipe(unique())
+  .on('data', console.log);
+
+```
+
+### Dedupe a ReadStream based on an object property:
+
+``` js
+// Use name as the key field to dedupe on. Will only print one object
+makeStreamOfObjects()
+  .pipe(unique('name'))
+  .on('data', console.log);
+```
+
+### Dedupe a ReadStream based on a custom function:
+
+``` js
+// Use a custom function to dedupe on. Use the 'number' field. Will only print one object.
+makeStreamOfObjects()
+  .pipe(function (data) {
+    return data.number;
+  })
+  .on('data', console.log);
+```
+
+## Dedupe multiple streams
+
+The reason I wrote this was to dedupe multiple object streams:
+
+``` js
+var aggregator = unique();
+
+// Stream 1
+makeStreamOfObjects()
+  .pipe(aggregator);
+
+// Stream 2
+makeStreamOfObjects()
+  .pipe(aggregator);
+
+// Stream 3
+makeStreamOfObjects()
+  .pipe(aggregator);
+
+aggregator.on('data', console.log);
+```
+
+## Use a custom store to record keys that have been encountered
+
+By default a set is used to store keys encountered so far, in order to check new ones for
+uniqueness. You can supply your own store instead, providing it supports the add(key) and 
+has(key) methods. This could allow you to use a persistent store so that already encountered
+objects are not re-streamed when node is reloaded.
+
+``` js
+var keyStore = {
+  store: {},
+
+  add: function(key) {
+    this.store[key] = true;
+  },
+
+  has: function(key) {
+    return this.store[key] !== undefined;
+  }
+};
+    
+makeStreamOfObjects()
+  .pipe(unique('name', keyStore))
+  .on('data', console.log);
+```

+through2-filter
+===============
+
+[![NPM](https://nodei.co/npm/through2-filter.png)](https://nodei.co/npm/through2-filter/)
+
+This is a super thin wrapper around [through2](http://npm.im/through2) that works like `Array.prototype.filter` but for streams.
+
+For when through2 is just too verbose :wink:
+
+Note you will **NOT** be able to alter the content of the chunks. This is intended for filtering only. If you want to modify the stream content, use either `through2` or `through2-map`.
+
+```js
+var filter = require("through2-filter")
+
+var skip = filter(function (chunk) {
+  // skip buffers longer than 100
+  return chunk.length < 100
+})
+
+// vs. with through2:
+var skip = through2(function (chunk, encoding, callback) {
+  // skip buffers longer than 100
+  if (chunk.length < 100) this.push(chunk)
+  return callback()
+})
+
+// Then use your filter:
+source.pipe(skip).pipe(sink)
+
+// Additionally accepts `wantStrings` argument to conver buffers into strings
+var alphanum = new RegExp("^[A-Za-z0-1]+$")
+var scrub = filter({wantStrings: true}, function (str) {
+  return alphanum.exec(str)
+})
+
+// Works like `Array.prototype.filter` meaning you can specify a function that
+// takes up to two* arguments: fn(element, index)
+var skip10 = filter(function (element, index) {
+  return index > 10
+})
+```
+
+*Differences from `Array.prototype.filter`:
+  * No third `array` callback argument. That would require realizing the entire stream, which is generally counter-productive to stream operations.
+  * `Array.prototype.filter` doesn't modify the source Array, which is somewhat nonsensical when applied to streams.
+
+API
+---
+
+`require("through2-filter")([options], fn)`
+---
+
+Create a `through2-filter` instance that will call `fn(chunk)`. If `fn(chunk)` returns "true" the chunk will be passed downstream. Otherwise it will be dropped.
+
+`require("through2-filter").ctor([options], fn)`
+---
+
+Create a `through2-filter` Type that can be instantiated via `new Type()` or `Type()` to create reusable spies.
+
+`require("through2-filter").obj([options], fn)`
+---
+
+Create a `through2-filter` that defaults to `objectMode = true`.
+
+`require("through2-filter").objCtor([options], fn)`
+---
+
+Create a `through2-filter` Type that defaults to `objectMode = true`.
+
+Options
+-------
+
+  * wantStrings: Automatically call chunk.toString() for the super lazy.
+  * all other through2 options

+
+> Delete nested properties from an object using dot notation.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save unset-value
+```
+
+## Usage
+
+```js
+var unset = require('unset-value');
+
+var obj = {a: {b: {c: 'd', e: 'f'}}};
+unset(obj, 'a.b.c');
+console.log(obj);
+//=> {a: {b: {e: 'f'}}};
+```
+
+## Examples
+
+### Updates the object when a property is deleted
+
+```js
+var obj = {a: 'b'};
+unset(obj, 'a');
+console.log(obj);
+//=> {}
+```
+
+### Returns true when a property is deleted
+
+```js
+unset({a: 'b'}, 'a') // true
+```
+
+### Returns `true` when a property does not exist
+
+This is consistent with `delete` behavior in that it does not
+throw when a property does not exist.
+
+```js
+unset({a: {b: {c: 'd'}}}, 'd') // true
+```
+
+### delete nested values
+
+```js
+var one = {a: {b: {c: 'd'}}};
+unset(one, 'a.b');
+console.log(one);
+//=> {a: {}}
+
+var two = {a: {b: {c: 'd'}}};
+unset(two, 'a.b.c');
+console.log(two);
+//=> {a: {b: {}}}
+
+var three = {a: {b: {c: 'd', e: 'f'}}};
+unset(three, 'a.b.c');
+console.log(three);
+//=> {a: {b: {e: 'f'}}}
+```
+
+### throws on invalid args
+
+```js
+unset();
+// 'expected an object.'
+```

+## key
+
+Changelog entries are classified using the following labels from [keep-a-changelog][]:
+
+* `added`: for new features
+* `changed`: for changes in existing functionality
+* `deprecated`: for once-stable features removed in upcoming releases
+* `removed`: for deprecated features removed in this release
+* `fixed`: for any bug fixes
+
+Custom labels used in this changelog:
+
+* `dependencies`: bumps dependencies
+* `housekeeping`: code re-organization, minor edits, or other changes that don't fit in one of the other categories.
+
+**Heads up!**
+
+Please [let us know](../../issues) if any of the following heading links are broken. Thanks!
+
+## [0.7.3] - 2016-07-21
+
+**fixed**
+
+- ensure `app.cwd` in the current instance is the cwd defined by the user on the options or argv.
+
+## [0.7.0] - 2016-07-21
+
+**added**
+
+- as of v0.7.0, we will begin using the [keep-a-changelog][] format for release history
+- adds support user-defined templates
+- adds support for `app.home()`, which resolves to `~/` or the user-defined `options.homedir`. This directory is used to determine the base directory for user-defined templates.
+- adds support for [common-config](https://github.com/jonschlinkert/common-config). Exposed on the `app.common` object (e.g. `app.common.set()` etc)
+- adds experimental support for a `home` updater. If an `updatefile.js` exists in the `~/update` directory (this will be customizable, but it's not yet), this file will be loaded and `.use()`d as a plugin before other updaters are loaded. You can use this to set options, add defaults, etc. But you can also run it explictly via commandline with the `update home` command.
+
+**fixed**
+
+- fixes `app.cwd` so that it's updated when `app.options.dest` (`--dest`) is set
+- ensure args are parsed consistently
+
+## [0.6.0]
+
+- Swap out [base][] for [assemble-core][] (which uses Base via [templates][]). This allows updaters to seamlessly run generators from [generate][], [assemble][], or [verb][] (when a file needs to be created, or re-created for example)
+- Adds [assemble-loader][] to support glob patterns in collection methods
+
+## [0.5.0]
+
+First stable release!

+
+## Quickstart
+
+Install Update's CLI and an example [updater](#updaters) globally:
+
+```sh
+$ npm install --global update && updater-example
+```
+
+Initialize `update`:
+
+```sh
+$ update init
+```
+
+Run update:
+
+```sh
+$ update
+```
+
+## Overview
+
+### What does Update do?
+
+All updating is accomplished using plugins called _updaters_, which are run by command line or API, and can be installed globally, locally, or created in a local `updatefile.js`.
+
+You can create your own [updaters](docs/updaters.md) using Update's API, or install updaters using [npm](https://www.npmjs.com/), to do things like:
+
+* create continuity and consistency across projects
+* enforce conventions across all of your projects
+* instantly update an old or inherited project to your latest personal preferences (convert tabs to spaces, convert from `jshint` to `eslint` or the other way around, or any other detail)
+* reformat code to meet your standards
+* convert a config file to a different format (json to yaml, yaml to json, etc)
+* update files that are typically excluded from build cycles, and are often forgotten about after they're created. For example:
+  - fix dates in copyrights, [licenses](https://github.com/update/updater-license) and banners
+  - remove deprecated fields from [project manifests](https://github.com/update/updater-package)
+  - update settings in [runtime config](https://github.com/update/updater-eslint) files, preferences in [dotfiles](https://github.com/update/updater-editorconfig)
+* after initializing a new project with a project generator, like [generate](https://github.com/generate/generate) or Google's Yeoman, you can "normalize" all of the generated files to use your own preferences
+
+### Why should I use Update?
+
+* **be more productive**: Update eliminates time spent on things that _can be automated_, but typically aren't since they either don't need to be done often, don't fit into the build cycle or a project's deliverables, or because they're usually updated manually. As code projects mature, time spent on these things tend to stay linear or increase as the size of a community grows. If you maintain more than a handful of projects, time spent on these things compounds with each new project under your stewardship.
+* **your way, instantly**: updaters can be published to and installed from npm, but you can also easily create your own [personal updaters](docs/symlinking-updaters.md). Once your updaters are setup, just run `update init`, then projects under your maintenance will convert to the the conventions you prefer within milliseconds after running `update`.
+* **plugin ecosystem**: any plugins that work with [Base applications](#discovering-plugins) will work also with Update. Which means you can use plugins (or generators) from [assemble](https://github.com/assemble/assemble), [verb](https://github.com/verbose/verb), and [generate](https://github.com/generate/generate), to name a few.
+* **well tested**: with more than 1,250 unit tests
+
+### Examples
+
+Here are some random example commits after running `$ update`.
+
+**Project**/**Commit** | **Updaters used**
+
+--- | ---
+[generate-scaffold](https://github.com/generate/generate-scaffold/commit/440d71f7293cb1f79445c0161440afbb266a2fbe) |  `editorconfig`, `travis`
+[updater-editorconfig](https://github.com/update/updater-editorconfig/commit/b7bd0aa616519440fa4a0d29d3aefac26787cbaf) | `editorconfig`, `eslint`, `travis`, `license`
+[expand-target](https://github.com/jonschlinkert/expand-target/commit/48d70a0bc95d8eb3f7def615b7e231e8f93816e8) | `editorconfig`, `eslint`, `travis`, `package`
+
+### Features
+
+* **unparalleled flow control**: through the use of [updaters](docs/updaters.md), [sub-updaters](https://github.com/update/getting-started) and [tasks](docs/tasks.md)
+* **generators**: support for [generate](https://github.com/generate/generate) generators. If your updater needs to create new files, there might be a [generator for that](https://www.npmjs.com/browse/keyword/generate-generator). Just use the generator the same way you would use an [updater](docs/updaters.md).
+* **render templates**: use templates to create new files, or replace existing files
+* **prompts**: It's easy to create custom prompts. Answers to prompts can be used as context for rendering templates, for settings options, determining file names, directory structure, and anything else that requires user feedback.
+* **any engine**: use any template engine to render templates, including [handlebars](http://www.handlebarsjs.com/), [lodash](https://lodash.com/), [swig](https://github.com/paularmstrong/swig) and [pug](http://jade-lang.com), or anything supported by [consolidate](https://github.com/visionmedia/consolidate.js).
+* **data**: gather data from the user's environment to populate "hints" in user prompts or for rendering templates
+* **fs**: in the spirit of [gulp](http://gulpjs.com), use `.src` and `.dest` to read and write globs of files.
+* **vinyl**: files and templates are [vinyl](http://github.com/gulpjs/vinyl) files
+* **streams**: full support for [gulp](http://gulpjs.com) and [assemble](https://github.com/assemble/assemble) plugins
+* **smart plugins**: Update is built on [base](https://github.com/node-base/base), so any "smart" plugin from the Base ecosystem can be used
+* **stores**: persist configuration settings, global defaults, project-specific defaults, answers to prompts, and so on.
+* much more!
+
+## CLI
+
+### Installing update
+
+**Install update**
+
+To use Update's CLI, `update` must first be installed globally with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --global update
+```
+
+This adds the `update` command to your system path, allowing it to be run from anywhere.
+
+### Installing updaters
+
+Updaters can be [found on npm](https://www.npmjs.com/browse/keyword/update-updater), but if you're not familiar with how Update works, we recommend installing  `updater-example`:
+
+```sh
+$ npm install --global updater-example
+```
+
+**Create "example.txt"**
+
+In the current working directory, create an empty file named `example.txt`.
+
+**Run**
+
+As a habit, when using `update` make sure your work is committed, then run:
+
+```sh
+$ update example
+```
+
+This appends the string `foo` to the contents of `example.txt`. Visit the [updater-example](https://github.com/update/updater-example) project for additional steps and guidance.
+
+## Tasks
+
+Update ships with the following built-in [tasks](docs/tasks.md). These will be externalized to an updater or [generate](https://github.com/generate/generate) generator at some point.
+
+### [init](lib/updatefile.js#L29)
+
+Select the updaters to run every time `update` is run. Use `--add` to add additional updaters, and `--remove` to remove them. You can run this command whenever you want to update your preferences, like after installing new updaters.
+
+**Example**
+
+```sh
+$ update init
+```
+
+### [list](lib/updatefile.js#L64)
+
+Display a list of currently installed updaters.
+
+**Example**
+
+```sh
+$ update defaults:list
+# aliased as
+$ update list
+```
+
+### [help](lib/updatefile.js#L85)
+
+Display a help [menu](#help-menu) of available commands and flags.
+
+**Example**
+
+```sh
+$ update defaults:help
+# aliased as
+$ update help
+```
+
+### [show](lib/updatefile.js#L101)
+
+Show the list of updaters that are registered to run on the current project.
+
+**Example**
+
+```sh
+$ update defaults:show
+# aliased as
+$ update show
+```
+
+### [help](lib/updatefile.js#L120)
+
+Default task for the built-in `defaults` generator.
+
+**Example**
+
+```sh
+$ update help
+```
+
+## Help menu
+
+```console
+$ update help
+
+  Usage: update <command> [options]
+
+  Command: updater or tasks to run
+
+  Options:
+
+    --config, -c      Save a configuration value to the `update` object in package.json
+    --cwd             Set or display the current working directory
+    --help, -h        Display this help menu
+    --init, -i        Prompts you to choose the updaters to automatically run (your "queue")
+    --add             Add updaters to your queue
+    --remove          Remove updaters from your queue
+    --run             Force tasks to run regardless of command line flags used
+    --silent, -S      Silence all tasks and updaters in the terminal
+    --show <key>      Display the value of <key>
+    --version, -V     Display the current version of update
+    --verbose, -v     Display all verbose logging messages
+
+  Examples:
+
+    # run updater "foo"
+    $ update foo
+
+    # run task "bar" from updater "foo"
+    $ update foo:bar
+
+    # run multiple tasks from updater "foo"
+    $ update foo:bar,baz,qux
+
+    # run a sub-generator from updater "foo"
+    $ update foo.abc
+
+    # run task "xyz" from sub-generator "foo.abc"
+    $ update foo.abc:xyz
+
+    Update attempts to automatically determine if "foo" is a task or updater.
+    If there is a conflict, you can force update to run updater "foo"
+    by specifying its default task. Example: `$ update foo:default`
+```

+
+### Updaters
+
+#### Discovering updaters
+
+* Find updaters to install by [searching npm](https://www.npmjs.com/browse/keyword/update-updater) for packages with the keyword `updateupdater`
+* Visit [Update's GitHub org](https://github.com/update) to see the updaters maintained by the core team
+
+#### Discovering plugins
+
+Plugins from any applications built on [base](https://github.com/node-base/base) should work with Update (and can be used in your updater):
+
+* [base](https://www.npmjs.com/browse/keyword/baseplugin): find base plugins on npm using the `baseplugin` keyword
+* [assemble](https://www.npmjs.com/browse/keyword/assembleplugin): find assemble plugins on npm using the `assembleplugin` keyword
+* [generate](https://www.npmjs.com/browse/keyword/generateplugin): find generate plugins on npm using the `generateplugin` keyword
+* [templates](https://www.npmjs.com/browse/keyword/templatesplugin): find templates plugins on npm using the `templatesplugin` keyword
+* [update][update-plugin]: find update plugins on npm using the `updateplugin` keyword
+* [verb](https://www.npmjs.com/browse/keyword/verbplugin): find verb plugins on npm using the `verbplugin` keyword
+
+#### Authoring updaters
+
+Visit the [updater documentation](docs/updaters.md) guide to learn how to use, author and publish updaters.
+
+## Configuration
+
+Customize settings and default behavior using the `update` property in package.json. These values will override global defaults.
+
+```js
+{
+  "update": {
+    "updaters": ["package", "license", "keywords"]
+  }
+}
+```
+
+### Options
+
+The following options may be defined in package.json.
+
+#### updaters
+
+The updaters to run on the current project.
+
+**Example**
+
+Run `updater-license` and `updater-package` on the current project:
+
+```js
+{
+  "update": {
+    "updaters": ["package", "license"]
+  }
+}
+```

+## Release History
+
+### key
+
+Changelog entries are classified using the following labels from [keep-a-changelog](https://github.com/olivierlacan/keep-a-changelog):
+
+* `added`: for new features
+* `changed`: for changes in existing functionality
+* `deprecated`: for once-stable features removed in upcoming releases
+* `removed`: for deprecated features removed in this release
+* `fixed`: for any bug fixes
+
+Custom labels used in this changelog:
+
+* `dependencies`: bumps dependencies
+* `housekeeping`: code re-organization, minor edits, or other changes that don't fit in one of the other categories.
+
+**Heads up!**
+
+Please [let us know](../../issues) if any of the following heading links are broken. Thanks!
+
+### [0.7.3](https://github.com/update/update/compare/0.7.0...0.7.3) - 2016-07-21
+
+**fixed**
+
+* ensure `app.cwd` in the current instance is the cwd defined by the user on the options or argv.
+
+### [0.7.0](https://github.com/update/update/compare/0.6.0...0.7.0) - 2016-07-21
+
+**added**
+
+* as of v0.7.0, we will begin using the [keep-a-changelog](https://github.com/olivierlacan/keep-a-changelog) format for release history
+* adds support user-defined templates
+* adds support for `app.home()`, which resolves to `~/` or the user-defined `options.homedir`. This directory is used to determine the base directory for user-defined templates.
+* adds support for [common-config](https://github.com/jonschlinkert/common-config). Exposed on the `app.common` object (e.g. `app.common.set()` etc)
+* adds experimental support for a `home` updater. If an `updatefile.js` exists in the `~/update` directory (this will be customizable, but it's not yet), this file will be loaded and `.use()`d as a plugin before other updaters are loaded. You can use this to set options, add defaults, etc. But you can also run it explictly via commandline with the `update home` command.
+
+**fixed**
+
+* fixes `app.cwd` so that it's updated when `app.options.dest` (`--dest`) is set
+* ensure args are parsed consistently
+
+### [0.6.0](https://github.com/update/update/compare/0.5.0...0.6.0)
+
+* Swap out [base](https://github.com/node-base/base) for [assemble-core](https://github.com/assemble/assemble-core) (which uses Base via [templates](https://github.com/jonschlinkert/templates)). This allows updaters to seamlessly run generators from [generate](https://github.com/generate/generate), [assemble](https://github.com/assemble/assemble), or [verb](https://github.com/verbose/verb) (when a file needs to be created, or re-created for example)
+* Adds [assemble-loader](https://github.com/assemble/assemble-loader) to support glob patterns in collection methods
+
+### [0.5.0]
+
+First stable release!

+# Upper Case
+
+[![NPM version][npm-image]][npm-url]
+[![NPM downloads][downloads-image]][downloads-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+
+Upper case a string.
+
+Supports Unicode (non-ASCII characters) and non-string entities, such as objects with a `toString` property, numbers and booleans. Empty values (`null` and `undefined`) will result in an empty string.
+
+## Installation
+
+```
+npm install upper-case --save
+```
+
+## Usage
+
+```js
+var upperCase = require('upper-case')
+
+upperCase(null)           //=> ""
+upperCase('string')       //=> "STRING"
+upperCase('string', 'tr') //=> "STRİNG"
+
+upperCase({ toString: function () { return 'test' } }) //=> "TEST"
+```

+# use [![NPM version](https://badge.fury.io/js/use.svg)](http://badge.fury.io/js/use)  [![Build Status](https://travis-ci.org/jonschlinkert/use.svg)](https://travis-ci.org/jonschlinkert/use)
+
+> Easily add plugin support to your node.js application.
+
+A different take on plugin handling! This is not a middleware system, if you need something that handles async middleware, [ware](https://github.com/segmentio/ware) is great for that.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i use --save
+```
+
+## Usage
+
+```js
+var use = require('use');
+```
+
+See the [examples folder](./examples) for usage examples.
+
+## API
+
+### [.use](index.js#L48)
+
+Define a plugin function to be passed to use. The only parameter exposed to the plugin is `app`, the object or function. passed to `use(app)`. `app` is also exposed as `this` in plugins.
+
+Additionally, **if a plugin returns a function, the function will
+be pushed onto the `fns` array**, allowing the plugin to be
+called at a later point by the `run` method.
+
+**Params**
+
+* `fn` **{Function}**: plugin function to call
+
+**Example**
+
+```js
+var use = require('use');
+
+// define a plugin
+function foo(app) {
+  // do stuff
+}
+
+var app = function(){};
+use(app);
+
+// register plugins
+app.use(foo);
+app.use(bar);
+app.use(baz);
+```
+
+### [.run](index.js#L64)
+
+Run all plugins on `fns`. Any plugin that returns a function when called by `use` is pushed onto the `fns` array.
+
+**Params**
+
+* `value` **{Object}**: Object to be modified by plugins.
+* `returns` **{Object}**: Returns the object passed to `run`
+
+**Example**
+
+```js
+var config = {};
+app.run(config);
+```

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```

+[Vinyl][vinyl] adapter for the file system.
+
+## What is Vinyl?
+
+[Vinyl][vinyl] is a very simple metadata object that describes a file. When you think of a file, two attributes come to mind: `path` and `contents`. These are the main attributes on a [Vinyl][vinyl] object. A file does not necessarily represent something on your computer’s file system. You have files on S3, FTP, Dropbox, Box, CloudThingly.io and other services. [Vinyl][vinyl] can be used to describe files from all of these sources.
+
+## What is a Vinyl Adapter?
+
+While Vinyl provides a clean way to describe a file, we now need a way to access these files. Each file source needs what I call a "Vinyl adapter". A Vinyl adapter simply exposes a `src(globs)` and a `dest(folder)` method. Each return a stream. The `src` stream produces Vinyl objects, and the `dest` stream consumes Vinyl objects. Vinyl adapters can expose extra methods that might be specific to their input/output medium, such as the `symlink` method `vinyl-fs` provides.
+
+## Usage
+
+```javascript
+var map = require('map-stream');
+var vfs = require('vinyl-fs');
+
+var log = function(file, cb) {
+  console.log(file.path);
+  cb(null, file);
+};
+
+vfs.src(['./js/**/*.js', '!./js/vendor/*.js'])
+  .pipe(map(log))
+  .pipe(vfs.dest('./output'));
+```
+
+## API
+
+### `src(globs[, options])`
+
+Takes a glob string or an array of glob strings as the first argument and an options object as the second.
+Returns a stream of [vinyl] `File` objects.
+
+__Note: UTF-8 BOM will be stripped from all UTF-8 files read with `.src` unless disabled in the options.__
+
+#### Globs
+
+Globs are executed in order, so negations should follow positive globs.
+
+For example:
+
+```js
+fs.src(['!b*.js', '*.js'])
+```
+
+would not exclude any files, but the following would:
+
+```js
+fs.src(['*.js', '!b*.js'])
+```
+
+#### Options
+
+##### `options.cwd`
+
+The working directory the folder is relative to.
+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.base`
+
+The folder relative to the cwd. This is used to determine the file names when saving in `.dest()`.
+
+Type: `String`
+
+Default: The part of the path before the glob (if any) begins. For example, `path/to/**/*.js` would resolve to `path/to`. If there is no glob (i.e. a file path with no pattern), then the dirname of the path is used. For example, `path/to/some/file.js` would resolve to `path/to/some`.
+
+##### `options.buffer`
+
+Whether or not you want to buffer the file contents into memory. Setting to `false` will make `file.contents` a paused Stream.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.read`
+
+Whether or not you want the file to be read at all. Useful for stuff like removing files. Setting to `false` will make `file.contents` `null` and will disable writing the file to disk via `.dest()`.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.since`
+
+Only streams files that have been modified since the time specified.
+
+Type: `Date` or `Number`
+
+Default: `undefined`
+
+##### `options.stripBOM`
+
+Causes the BOM to be stripped on UTF-8 encoded files. Set to `false` if you need the BOM for some reason.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### `options.passthrough`
+
+Allows `.src` to be used in the middle of a pipeline (using a duplex stream) which passes through all objects received and adds all files globbed to the stream.
+
+Type: `Boolean`
+
+Default: `false`
+
+##### `options.sourcemaps`
+
+Enables sourcemap support on files passed through the stream.  Will load inline sourcemaps and resolve sourcemap links from files. Uses [gulp-sourcemaps] under the hood.
+
+Type: `Boolean`
+
+Default: `false`
+
+##### `options.followSymlinks` - `true` if you want
+
+Whether or not to recursively resolve symlinks to their targets. Setting to `false` to preserve them as symlinks and make `file.symlink` equal the original symlink's target path.
+
+Type: `Boolean`
+
+Default: `true`
+
+##### other
+
+Any glob-related options are documented in [glob-stream] and [node-glob].
+Any through2-related options are documented in [through2].
+
+### `dest(folder[, options])`
+
+Takes a folder path string or a function as the first argument and an options object as the second. If given a function, it will be called with each [vinyl] `File` object and must return a folder path.
+Returns a stream that accepts [vinyl] `File` objects, writes them to disk at the folder/cwd specified, and passes them downstream so you can keep piping these around.
+
+Once the file is written to disk, an attempt is made to determine if the `stat.mode`, `stat.mtime` and `stat.atime` of the [vinyl] `File` object differ from the file on the filesystem.
+If they differ and the running process owns the file, the corresponding filesystem metadata is updated.
+If they don't differ or the process doesn't own the file, the attempt is skipped silently.
+__This functionality is disabled on Windows operating systems or any other OS that doesn't support `process.getuid` or `process.geteuid` in node. This is due to Windows having very unexpected results through usage of `fs.fchmod` and `fs.futimes`.__
+
+If the file has a `symlink` attribute specifying a target path, then a symlink will be created.
+
+__Note: The file will be modified after being written to this stream.__
+  - `cwd`, `base`, and `path` will be overwritten to match the folder.
+  - `stat` will be updated to match the file on the filesystem.
+  - `contents` will have it's position reset to the beginning if it is a stream.
+
+#### Options
+
+##### `options.cwd`
+
+The working directory the folder is relative to.
+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.base`
+
+The folder relative to the cwd. This is used to determine the file names when saving in `.dest()`. Can also be a function that takes in a file and returns a folder path.
+
+Type: `String` or `Function`
+
+Default: The `cwd` resolved to the folder path.
+
+##### `options.mode`
+
+The mode the files should be created with.
+
+Type: `Number`
+
+Default: The `mode` of the input file (`file.stat.mode`) if any, or the process mode if the input file has no `mode` property.
+
+##### `options.dirMode`
+
+The mode the directory should be created with.
+
+Type: `Number`
+
+Default: The process `mode`.
+
+##### `options.overwrite`
+
+Whether or not existing files with the same path should be overwritten. Can also be a function that takes in a file and returns `true` or `false`.
+
+Type: `Boolean` or `Function`
+
+Default: `true` (always overwrite existing files)
+
+##### `options.sourcemaps`
+
+Enables sourcemap support on files passed through the stream.  Will write inline soucemaps if specified as `true`.
+Specifying a `string` is shorthand for the path option. Uses [gulp-sourcemaps] under the hood.
+
+Examples:
+
+```js
+// Write as inline comments
+vfs.dest('./', {
+  sourcemaps: true
+});
+
+// Write as files in the same folder
+vfs.dest('./', {
+  sourcemaps: '.'
+});
+
+// Any other options are passed through to [gulp-sourcemaps]
+vfs.dest('./', {
+  sourcemaps: {
+    path: '.',
+    addComment: false,
+    includeContent: false
+  }
+});
+```
+
+Type: `Boolean`, `String` or `Object`
+
+Default: `undefined` (do not write sourcemaps)
+
+##### other
+
+Any through2-related options are documented in [through2].
+
+### `symlink(folder[, options])`
+
+Takes a folder path string or a function as the first argument and an options object as the second. If given a function, it will be called with each [vinyl] `File` object and must return a folder path.
+Returns a stream that accepts [vinyl] `File` objects, create a symbolic link (i.e. symlink) at the folder/cwd specified, and passes them downstream so you can keep piping these around.
+
+__Note: The file will be modified after being written to this stream.__
+  - `cwd`, `base`, and `path` will be overwritten to match the folder.
+
+#### Options
+
+##### `options.cwd`
+
+The working directory the folder is relative to.
+
+Type: `String`
+
+Default: `process.cwd()`
+
+##### `options.base`
+
+The folder relative to the cwd. This is used to determine the file names when saving in `.symlink()`. Can also be a function that takes in a file and returns a folder path.
+
+Type: `String` or `Function`
+
+Default: The `cwd` resolved to the folder path.
+
+##### `options.dirMode`
+
+The mode the directory should be created with.
+
+Type: `Number`
+
+Default: The process mode.
+
+##### other
+
+Any through2-related options are documented in [through2].

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install base --save
+```
+
+## Usage
+
+```js
+var base = require('base');
+```
+
+**inherit**
+
+```js
+function App() {
+  base.call(this);
+}
+base.extend(App);
+
+var app = new App();
+app.set('a', 'b');
+app.get('a');
+//=> 'b';
+```
+
+**instantiate**
+
+```js
+var app = base();
+app.set('foo', 'bar');
+console.log(app.foo);
+//=> 'bar'
+```
+
+**Inherit or instantiate with a namespace**
+
+A `.namespace()` method is exposed on the exported function to allow you to create a custom namespace for setting/getting on the instance.
+
+```js
+var Base = require('base')
+var base = Base.namespace('cache');
+
+var app = base();
+app.set('foo', 'bar');
+console.log(app.cache.foo);
+//=> 'bar'
+```
+
+## API
+
+All of the methods from [cache-base](https://github.com/jonschlinkert/cache-base) are exposed on the `base` API, as well as the following methods.
+
+### [Base](index.js#L41)
+
+Create an instance of `Base` with `config` and `options`.
+
+**Params**
+
+* `config` **{Object}**: passed to [cache-base](https://github.com/jonschlinkert/cache-base)
+* `options` **{Object}**
+
+**Example**
+
+```js
+var app = new Base({baz: 'qux'}, {yeah: 123, nope: 456});
+
+app.set('foo', 'bar');
+
+console.log(app.get('foo')); //=> 'bar'
+console.log(app.get('baz')); //=> 'qux'
+console.log(app.get('yeah')); //=> undefined
+
+console.log(app.foo); //=> 'bar'
+console.log(app.baz); //=> 'qux'
+console.log(app.yeah); //=> undefined
+
+console.log(app.options.yeah); //=> 123
+console.log(app.options.nope); //=> 456
+```
+
+### [.is](index.js#L104)
+
+Set the given `name` on `app._name` and `app.is*` properties. Used for doing lookups in plugins.
+
+**Params**
+
+* `name` **{String}**
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+app.is('foo');
+console.log(app._name);
+//=> 'foo'
+console.log(app.isFoo);
+//=> true
+app.is('bar');
+console.log(app.isFoo);
+//=> true
+console.log(app.isBar);
+//=> true
+console.log(app._name);
+//=> 'bar'
+```
+
+### [.isRegistered](index.js#L155)
+
+Returns true if a plugin has already been registered on an instance.
+
+Plugin implementors are encouraged to use this first thing in a plugin
+to prevent the plugin from being called more than once on the same
+instance.
+
+**Params**
+
+* `name` **{String}**: The plugin name.
+* `register` **{Boolean}**: If the plugin if not already registered, to record it as being registered pass `true` as the second argument.
+* `returns` **{Boolean}**: Returns true if a plugin is already registered.
+
+**Events**
+
+* `emits`: `plugin` Emits the name of the plugin.
+
+**Example**
+
+```js
+var base = new Base();
+base.use(function(app) {
+  if (app.isRegistered('myPlugin')) return;
+  // do stuff to `app`
+});
+
+// to also record the plugin as being registered
+base.use(function(app) {
+  if (app.isRegistered('myPlugin', true)) return;
+  // do stuff to `app`
+});
+```
+
+### [.assertPlugin](index.js#L182)
+
+Throws an error when plugin `name` is not registered.
+
+**Params**
+
+* `name` **{String}**: The plugin name.
+
+**Example**
+
+```js
+var base = new Base();
+base.use(function(app) {
+  app.assertPlugin('base-foo');
+  app.assertPlugin('base-bar');
+  app.assertPlugin('base-baz');
+});
+```
+
+### [.use](index.js#L206)
+
+Define a plugin function to be called immediately upon init. Plugins are chainable and the only parameter exposed to the plugin is the application instance.
+
+**Params**
+
+* `fn` **{Function}**: plugin function to call
+* `returns` **{Object}**: Returns the item instance for chaining.
+
+**Events**
+
+* `emits`: `use` with no arguments.
+
+**Example**
+
+```js
+var app = new Base()
+  .use(foo)
+  .use(bar)
+  .use(baz)
+```
+
+### [.lazy](index.js#L231)
+
+Lazily invoke a registered plugin. **Note** that this method can only be used with:
+
+1. plugins that _add a single method or property_ to `app`
+2. plugins that do not (themselves) add a getter/setter property (they're already lazy)
+3. plugins that do not return a function
+
+**Params**
+
+* `prop` **{String}**: The name of the property or method added by the plugin.
+* `fn` **{Function}**: The plugin function
+* `options` **{Object}**: Options to use when the plugin is invoked.
+* `returns` **{Object}**: Returns the instance for chaining
+
+**Example**
+
+```js
+app.lazy('store', require('base-store'));
+```
+
+### [.define](index.js#L263)
+
+Define a non-enumerable property on the instance. Dot-notation is **not supported** with `define`.
+
+**Params**
+
+* `key` **{String}**: The name of the property to define.
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `define` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+// arbitrary `render` function using lodash `template`
+define('render', function(str, locals) {
+  return _.template(str)(locals);
+});
+```
+
+### [.mixin](index.js#L282)
+
+Mix property `key` onto the Base prototype. If base-methods
+is inherited using `Base.extend` this method will be overridden
+by a new `mixin` method that will only add properties to the
+prototype of the inheriting application.
+
+**Params**
+
+* `key` **{String}**
+* `val` **{Object|Array}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+### [.base](index.js#L313)
+
+Getter/setter for a `base` (or shared) instance of `base` applications.
+
+This property only works when a "parent" instance is created on `app`.
+If `app.parent` is defined, the `base` getter ensures that the `base`
+instance is always the very first instance.
+
+**Example**
+
+```js
+var a = new Base();
+a.foo = 'bar';
+
+var b = new Base();
+b.parent = a;
+
+var c = new Base();
+c.parent = b;
+
+console.log(c.foo);
+//=> undefined
+console.log(c.base.foo);
+//=> 'bar'
+```
+
+### [.use](index.js#L337)
+
+Static method for adding global plugin functions that will be added to an instance when created.
+
+**Params**
+
+* `fn` **{Function}**: Plugin function to use on each instance.
+
+**Example**
+
+```js
+Base.use(function(app) {
+  app.foo = 'bar';
+});
+var app = new Base();
+console.log(app.foo);
+//=> 'bar'
+```
+
+### [.extend](index.js#L349)
+
+Static method for inheriting both the prototype and
+static methods of the `Base` class. See [class-utils](https://github.com/jonschlinkert/class-utils)
+for more details.
+
+### [.Base.mixin](index.js#L387)
+
+Static method for adding mixins to the prototype. When a function is returned from the mixin plugin, it will be added to an array so it can be used on inheriting classes via `Base.mixins(Child)`.
+
+**Params**
+
+* `fn` **{Function}**: Function to call
+
+**Example**
+
+```js
+Base.mixin(function fn(proto) {
+  proto.foo = function(msg) {
+    return 'foo ' + msg;
+  };
+  return fn;
+});
+```
+
+### [.Base.mixins](index.js#L408)
+
+Static method for running currently saved global mixin functions against a child constructor.
+
+**Params**
+
+* `Child` **{Function}**: Constructor function of a child class
+
+**Example**
+
+```js
+Base.extend(Child);
+Base.mixins(Child);
+```
+
+### [.inherit](index.js#L420)
+
+Similar to `util.inherit`, but copies all static properties,
+prototype properties, and descriptors from `Provider` to `Receiver`.
+[class-utils](https://github.com/jonschlinkert/class-utils) for more details.

+
+> Cache requires to be lazy-loaded when needed.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install lazy-cache --save
+```
+
+If you use webpack and are experiencing issues, try using [unlazy-loader](https://github.com/doowb/unlazy-loader), a webpack loader that fixes the bug that prevents webpack from working with native javascript getters.
+
+## Usage
+
+```js
+var utils = require('lazy-cache')(require);
+```
+
+**Use as a property on `lazy`**
+
+The module is also added as a property to the `lazy` function
+so it can be called without having to call a function first.
+
+```js
+var utils = require('lazy-cache')(require);
+
+// `npm install glob`
+utils('glob');
+
+// glob sync
+console.log(utils.glob.sync('*.js'));
+
+// glob async
+utils.glob('*.js', function (err, files) {
+  console.log(files);
+});
+```
+
+**Use as a function**
+
+```js
+var utils = require('lazy-cache')(require);
+var glob = utils('glob');
+
+// `glob` is a now a function that may be called when needed
+glob().sync('foo/*.js');
+```
+
+## Aliases
+
+An alias may be passed as the second argument if you don't want to use the automatically camel-cased variable name.
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+
+// alias `ansi-yellow` as `yellow`
+utils('ansi-yellow', 'yellow');
+console.log(utils.yellow('foo'));
+```
+
+## Browserify usage
+
+**Example**
+
+```js
+var utils = require('lazy-cache')(require);
+// temporarily re-assign `require` to trick browserify
+var fn = require;
+require = utils;
+// list module dependencies (here, `require` is actually `lazy-cache`)
+require('glob');
+require = fn; // restore the native `require` function
+
+/**
+ * Now you can use glob with the `utils.glob` variable
+ */
+
+// sync
+console.log(utils.glob.sync('*.js'));
+
+// async
+utils.glob('*.js', function (err, files) {
+  console.log(files.join('\n'));
+});
+```
+
+## Kill switch
+
+In certain rare edge cases it may be necessary to unlazy all lazy-cached dependencies (5 reported cases after ~30 million downloads).
+
+To force lazy-cache to immediately invoke all dependencies, do:
+
+```js
+process.env.UNLAZY = true;
+```
+

+```
+
+**Namespace**
+
+Define a custom property for storing values.
+
+```js
+var Cache = require('cache-base').namespace('data');
+var app = new Cache();

+console.log(app.data);
+//=> {a: 'b'}
+```
+
+## API
+
+### [namespace](index.js#L21)
+
+Create a `Cache` constructor that when instantiated will store values on the given `prop`.
+
+**Params**
+
+* `prop` **{String}**: The property name to use for storing values.
+* `returns` **{Function}**: Returns a custom `Cache` constructor
+
+**Example**
+
+```js
+var Cache = require('cache-base').namespace('data');
+var cache = new Cache();
+
+cache.set('foo', 'bar');
+//=> {data: {foo: 'bar'}}
+```
+
+### [Cache](index.js#L35)
+
+Create a new `Cache`. Internally the `Cache` constructor is created using the `namespace` function, with `cache` defined as the storage object.
+
+**Params**
+
+* `cache` **{Object}**: Optionally pass an object to initialize with.
+
+**Example**
+
+```js
+var app = new Cache();
+```
+
+### [.set](index.js#L76)
+
+Assign `value` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `set` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.on('set', function(key, val) {
+  // do something when `set` is emitted
+});
+
+app.set(key, value);
+
+// also takes an object or array
+app.set({name: 'Halle'});
+app.set([{foo: 'bar'}, {baz: 'quux'}]);
+console.log(app);
+//=> {name: 'Halle', foo: 'bar', baz: 'quux'}
+```
+
+### [.union](index.js#L106)
+
+Union `array` to `key`. Also emits `set` with the key and value.
+
+**Params**
+
+* `key` **{String}**
+* `value` **{any}**
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Example**
+
+```js
+app.union('a.b', ['foo']);
+app.union('a.b', ['bar']);
+console.log(app.get('a'));
+//=> {b: ['foo', 'bar']}
+```
+
+### [.get](index.js#L136)
+
+Return the value of `key`. Dot notation may be used to get [nested property values](https://github.com/jonschlinkert/get-value).
+
+**Params**
+
+* `key` **{String}**: The name of the property to get. Dot-notation may be used.
+* `returns` **{any}**: Returns the value of `key`
+
+**Events**
+
+* `emits`: `get` with `key` and `value` as arguments.
+
+**Example**
+
+```js
+app.set('a.b.c', 'd');
+app.get('a.b');
+//=> {c: 'd'}
+
+app.get(['a', 'b']);
+//=> {c: 'd'}
+```
+
+### [.has](index.js#L163)
+
+Return true if app has a stored value for `key`, false only if value is `undefined`.
+
+**Params**
+
+* `key` **{String}**
+* `returns` **{Boolean}**
+
+**Events**
+
+* `emits`: `has` with `key` and true or false as arguments.
+
+**Example**
+
+```js
+app.set('foo', 'bar');
+app.has('foo');
+//=> true
+```
+
+### [.del](index.js#L191)
+
+Delete one or more properties from the instance.
+
+**Params**
+
+* `key` **{String|Array}**: Property name or array of property names.
+* `returns` **{Object}**: Returns the instance for chaining.
+
+**Events**
+
+* `emits`: `del` with the `key` as the only argument.
+
+**Example**
+
+```js
+app.del(); // delete all
+// or
+app.del('foo');
+// or
+app.del(['foo', 'bar']);
+```
+
+### [.clear](index.js#L210)
+
+Reset the entire cache to an empty object.
+
+**Example**
+
+```js
+app.clear();
+```
+
+### [.visit](index.js#L227)
+
+Visit `method` over the properties in the given object, or map
+visit over the object-elements in an array.
+
+**Params**
+
+* `method` **{String}**: The name of the `base` method to call.
+* `val` **{Object|Array}**: The object or array to iterate over.
+* `returns` **{Object}**: Returns the instance for chaining.

+
+Map `visit` over an array of objects.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save map-visit
+```
+
+## Usage
+
+```js
+var mapVisit = require('map-visit');
+```
+
+## Assign or Merge vs. Visit
+
+Let's say you want to add a `set` method to your application that will:
+
+* set key-value pairs on a `data` object
+* extend objects onto the `data` object
+* extend arrays of objects onto the data object
+
+**Example using `extend`**
+
+Here is one way to accomplish this using Lo-Dash's `extend`:
+
+```js
+var _ = require('lodash');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      _.extend.apply(_, [obj.data].concat(key));
+    } else if (typeof key === 'object') {
+      _.extend(obj.data, key);
+    } else {
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
+```
+
+The above approach works fine for most use cases. But **if you also want to emit an event** each time a property is added to the `data` object. A better approach would be to use `visit`.
+
+**Example using `visit`**
+
+In this approach, when an array is passed to `set`, `mapVisit` calls `set` on each object in the array. When an object is passed, `visit` calls `set` on each property in the object. As a result, the `data` event will be emitted every time a property is added to `data`.
+
+```js
+var mapVisit = require('map-visit');
+var visit = require('object-visit');
+
+var obj = {
+  data: {},
+  set: function (key, value) {
+    if (Array.isArray(key)) {
+      mapVisit(obj, 'set', key);
+    } else if (typeof key === 'object') {
+      visit(obj, 'set', key);
+    } else {
+      // some event-emitter
+      console.log('emit', key, value);
+      obj.data[key] = value;
+    }
+  }
+};
+
+obj.set('a', 'a');
+obj.set([{b: 'b'}, {c: 'c'}]);
+obj.set({d: {e: 'f'}});
+obj.set({g: 'h', i: 'j', k: 'l'});
+
+console.log(obj.data);
+//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
+
+// events would look something like:
+// emit a a
+// emit b b
+// emit c c
+// emit d { e: 'f' }
+// emit g h
+// emit i j
+// emit k l
+```

+
+> Delete nested properties from an object using dot notation.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save unset-value
+```
+
+## Usage
+
+```js
+var unset = require('unset-value');
+
+var obj = {a: {b: {c: 'd', e: 'f'}}};
+unset(obj, 'a.b.c');
+console.log(obj);
+//=> {a: {b: {e: 'f'}}};
+```
+
+## Examples
+
+### Updates the object when a property is deleted
+
+```js
+var obj = {a: 'b'};
+unset(obj, 'a');
+console.log(obj);
+//=> {}
+```
+
+### Returns true when a property is deleted
+
+```js
+unset({a: 'b'}, 'a') // true
+```
+
+### Returns `true` when a property does not exist
+
+This is consistent with `delete` behavior in that it does not
+throw when a property does not exist.
+
+```js
+unset({a: {b: {c: 'd'}}}, 'd') // true
+```
+
+### delete nested values
+
+```js
+var one = {a: {b: {c: 'd'}}};
+unset(one, 'a.b');
+console.log(one);
+//=> {a: {}}
+
+var two = {a: {b: {c: 'd'}}};
+unset(two, 'a.b.c');
+console.log(two);
+//=> {a: {b: {}}}
+
+var three = {a: {b: {c: 'd', e: 'f'}}};
+unset(three, 'a.b.c');
+console.log(three);
+//=> {a: {b: {e: 'f'}}}
+```
+
+### throws on invalid args
+
+```js
+unset();
+// 'expected an object.'
+```

+
+Extends vinyl with render and compile methods, and properties used for rendering templates.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save vinyl-view
+```
+
+## Usage
+
+Use the same way you would use a [vinyl](http://github.com/gulpjs/vinyl) file:
+
+```js
+var View = require('vinyl-view');
+var view = new View({path: 'foo'});
+```
+
+## API
+
+### [View](index.js#L26)
+
+Create an instance of `View`. Optionally pass a default object to use.
+
+**Params**
+
+* `view` **{Object}**
+
+**Example**
+
+```js
+var view = new View({
+  path: 'foo.html',
+  contents: new Buffer('...')
+});
+```
+
+### [.compile](index.js#L57)
+
+Synchronously compile a view.
+
+**Params**
+
+* `locals` **{Object}**: Optionally pass locals to the engine.
+* `returns` **{Object}** `View`: instance, for chaining.
+
+**Example**
+
+```js
+var view = page.compile();
+view.fn({title: 'A'});
+view.fn({title: 'B'});
+view.fn({title: 'C'});
+```
+
+### [.renderSync](index.js#L75)
+
+Synchronously render templates in `view.content`.
+
+**Params**
+
+* `locals` **{Object}**: Optionally pass locals to the engine.
+* `returns` **{Object}** `View`: instance, for chaining.
+
+**Example**
+
+```js
+var view = new View({content: 'This is <%= title %>'});
+view.renderSync({title: 'Home'});
+console.log(view.content);
+```
+
+### [.render](index.js#L101)
+
+Asynchronously render templates in `view.content`.
+
+**Params**
+
+* `locals` **{Object}**: Context to use for rendering templates.
+
+**Example**
+
+```js
+view.render({title: 'Home'}, function(err, res) {
+  //=> view object with rendered `content`
+});
+```
+
+### [.context](index.js#L132)
+
+Create a context object from `locals` and the `view.data` and `view.locals` objects. The `view.data` property is typically created from front-matter, and `view.locals` is used when a `new View()` is created.
+
+This method be overridden either by defining a custom `view.options.context` function
+to customize context for a view instance, or static [View.context](#view-context) function to customize
+context for all view instances.
+
+**Params**
+
+* `locals` **{Object}**: Optionally pass a locals object to merge onto the context.
+* `returns` **{Object}**: Returns the context object.
+
+**Example**
+
+```js
+var page = new View({path: 'a/b/c.txt', locals: {a: 'b', c: 'd'}});
+var ctx = page.context({a: 'z'});
+console.log(ctx);
+//=> {a: 'z', c: 'd'}
+```
+
+### [.isType](index.js#L148)
+
+Returns true if the view is the given `viewType`. Returns `false` if no type is assigned. When used with vinyl-collections, types are assigned by their respective collections.
+
+**Params**
+
+* `type` **{String}**: (`renderable`, `partial`, `layout`)
+
+**Example**
+
+```js
+var view = new View({path: 'a/b/c.txt', viewType: 'partial'})
+view.isType('partial');
+```
+
+### [.View.context](index.js#L248)
+
+Define a custom static `View.context` function to override default `.context` behavior. See the [context](#context) docs for more info.
+
+**Params**
+
+* `locals` **{Object}**
+* `returns` **{Object}**
+
+**Example**
+
+```js
+// custom context function
+View.context = function(locals) {
+  // `this` is the view being rendered
+  return locals;
+};
+```

+## Information
+<table><tr><td>Package</td><td>vinyl</td></tr><tr><td>Description</td><td>A virtual file format</td></tr><tr><td>Node Version</td><td>>= 0.9</td></tr></table>
+
+## What is this?
+Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
+
+## File
+
+```javascript
+var File = require('vinyl');
+
+var coffeeFile = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee",
+  contents: new Buffer("test = 123")
+});
+```
+
+### isVinyl
+When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
+
+```js
+var File = require('vinyl');
+
+var dummy = new File({stuff});
+var notAFile = {};
+
+File.isVinyl(dummy); // true
+File.isVinyl(notAFile); // false
+```
+
+### isCustomProp
+Vinyl checks if a property is not managed internally, such as `sourceMap`. This is than used in `constructor(options)` when setting, and `clone()` when copying properties.
+
+```js
+var File = require('vinyl');
+
+File.isCustomProp('sourceMap'); // true
+File.isCustomProp('path'); // false -> internal getter/setter
+```
+
+Read more in [Extending Vinyl](#extending-vinyl).
+
+### constructor(options)
+#### options.cwd
+Type: `String`<br><br>Default: `process.cwd()`
+
+#### options.base
+Used for relative pathing. Typically where a glob starts.
+
+Type: `String`<br><br>Default: `options.cwd`
+
+#### options.path
+Full path to the file.
+
+Type: `String`<br><br>Default: `undefined`
+
+#### options.history
+Path history. Has no effect if `options.path` is passed.
+
+Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
+
+#### options.stat
+The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
+
+Type: `fs.Stats`<br><br>Default: `null`
+
+#### options.contents
+File contents.
+
+Type: `Buffer, Stream, or null`<br><br>Default: `null`
+
+#### options.{custom}
+Any other option properties will just be assigned to the new File object.
+
+```js
+var File = require('vinyl');
+
+var file = new File({foo: 'bar'});
+file.foo === 'bar'; // true
+```
+
+### isBuffer()
+Returns true if file.contents is a Buffer.
+
+### isStream()
+Returns true if file.contents is a Stream.
+
+### isNull()
+Returns true if file.contents is null.
+
+### clone([opt])
+Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
+
+If opt or opt.deep is false, custom attributes will not be deep-cloned.
+
+If opt.contents is false, it will copy file.contents Buffer's reference.
+
+### pipe(stream[, opt])
+If file.contents is a Buffer, it will write it to the stream.
+
+If file.contents is a Stream, it will pipe it to the stream.
+
+If file.contents is null, it will do nothing.
+
+If opt.end is false, the destination stream will not be ended (same as node core).
+
+Returns the stream.
+
+### inspect()
+Returns a pretty String interpretation of the File. Useful for console.log.
+
+### contents
+The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
+
+For example:
+
+```js
+if (file.isBuffer()) {
+    console.log(file.contents.toString()); // logs out the string of contents
+}
+```
+
+### path
+Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
+
+### history
+Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
+
+### relative
+Returns path.relative for the file base and file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.relative); // file.coffee
+```
+
+### dirname
+Gets and sets path.dirname for the file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.dirname); // /test
+
+file.dirname = '/specs';
+
+console.log(file.dirname); // /specs
+console.log(file.path); // /specs/file.coffee
+```
+
+### basename
+Gets and sets path.basename for the file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.basename); // file.coffee
+
+file.basename = 'file.js';
+
+console.log(file.basename); // file.js
+console.log(file.path); // /test/file.js
+```
+
+### stem
+Gets and sets stem (filename without suffix) for the file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.stem); // file
+
+file.stem = 'foo';
+
+console.log(file.stem); // foo
+console.log(file.path); // /test/foo.coffee
+```
+
+### extname
+Gets and sets path.extname for the file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.extname); // .coffee
+
+file.extname = '.js';
+
+console.log(file.extname); // .js
+console.log(file.path); // /test/file.js
+```
+
+## Extending Vinyl
+When extending Vinyl into your own class with extra features, you need to think about a few things.
+
+When you have your own properties that are managed internally, you need to extend the static `isCustomProp` method to return `false` when one of these properties is queried.
+
+```js
+const File = require('vinyl');
+
+const builtInProps = ['foo', '_foo'];
+
+class SuperFile extends File {
+  constructor(options) {
+    super(options);
+    this._foo = 'example internal read-only value';
+  }
+
+  get foo() {
+    return this._foo;
+  }
+
+  static isCustomProp(name) {
+    return super.isCustomProp(name) && builtInProps.indexOf(name) === -1;
+  }
+}
+```
+
+This makes properties `foo` and `_foo` ignored when cloning, and when passed in options to `constructor(options)` so they don't get assigned to the new object.
+
+Same goes for `clone()`. If you have your own internal stuff that needs special handling during cloning, you should extend it to do so.

+# which
+
+Like the unix `which` utility.
+
+Finds the first instance of a specified executable in the PATH
+environment variable.  Does not cache the results, so `hash -r` is not
+needed when the PATH changes.
+
+## USAGE
+
+```javascript
+var which = require('which')
+
+// async usage
+which('node', function (er, resolvedPath) {
+  // er is returned if no "node" is found on the PATH
+  // if it is found, then the absolute path to the exec is returned
+})
+
+// sync usage
+// throws if not found
+var resolved = which.sync('node')
+
+// if nothrow option is used, returns null if not found
+resolved = which.sync('node', {nothrow: true})
+
+// Pass options to override the PATH and PATHEXT environment vars.
+which('node', { path: someOtherPath }, function (er, resolved) {
+  if (er)
+    throw er
+  console.log('found at %j', resolved)
+})
+```
+
+## CLI USAGE
+
+Same as the BSD `which(1)` binary.
+
+```
+usage: which [-as] program ...
+```
+
+## OPTIONS
+
+You may pass an options object as the second argument.
+
+- `path`: Use instead of the `PATH` environment variable.
+- `pathExt`: Use instead of the `PATHEXT` environment variable.
+- `all`: Return all matches, instead of just the first one.  Note that
+  this means the function returns an array of strings instead of a
+  single string.

+
+Extend like a boss
+
+xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
+
+## Examples
+
+```js
+var extend = require("xtend")
+
+// extend returns a new object. Does not mutate arguments
+var combination = extend({
+    a: "a",
+    b: "c"
+}, {
+    b: "b"
+})
+// { a: "a", b: "b" }
+```

+
+
+The mighty option parser used by [yargs](https://github.com/bcoe/yargs).
+
+visit the [yargs website](http://yargs.js.org/) for more examples, and thorough usage instructions.
+
+<img width="250" src="yargs-logo.png">
+
+## Example
+
+```sh
+npm i yargs-parser --save
+```
+
+```js
+var argv = require('yargs-parser')(process.argv.slice(2));
+console.log(argv)
+```
+
+```sh
+node example.js --foo=33 --bar hello
+{ _: [], foo: 33, bar: 'hello' }
+```
+
+_or parse a string!_
+
+```js
+var argv = require('./')('--foo=99 --bar=33');
+console.log(argv)
+```
+
+```sh
+{ _: [], foo: 99, bar: 33 }
+```
+
+## API
+
+### require('yargs-parser')(args, opts={})
+
+Parses command line arguments returning a simple mapping of keys and values.
+
+**expects:**
+
+* `args`: an array or string representing the options to parse.
+* `opts`: provide a set of hints indicating how `args` should be parsed:
+  * `opts.alias`: an object representing the set of aliases for a key: `{alias: {foo: ['f']}}`.
+  * `opts.array`: indicate that keys should be parsed as an array: `{array: ['foo', 'bar']}`.
+  * `opts.boolean`: arguments should be parsed as booleans: `{boolean: ['x', 'y']}`.
+  * `opts.config`: indicate a key that represents a path to a configuration file (this file will be loaded and parsed).
+  * `opts.count`: indicate a key that should be used as a counter, e.g., `-vvv` = `{v: 3}`.
+  * `opts.default`: provide default values for keys: `{default: {x: 33, y: 'hello world!'}}`.
+  * `opts.envPrefix`: environment variables (`process.env`) with the prefix provided should be parsed.
+  * `opts.narg`: specify that a key requires `n` arguments: `{narg: {x: 2}}`.
+  * `opts.normalize`: `path.normalize()` will be applied to values set to this key.
+  * `opts.string`: keys should be treated as strings (even if they resemble a number `-x 33`).
+  * `opts.configuration`: provide configuration options to the yargs-parser (see: [configuration](#configuration)).
+  * `opts.number`: keys should be treated as numbers.
+
+**returns:**
+
+* `obj`: an object representing the parsed value of `args`
+  * `key/value`: key value pairs for each argument and their aliases.
+  * `_`: an array representing the positional arguments.
+
+### require('yargs-parser').detailed(args, opts={})
+
+Parses a command line string, returning detailed information required by the
+yargs engine.
+
+**expects:**
+
+* `args`: an array or string representing options to parse.
+* `opts`: provide a set of hints indicating how `args`, inputs are identical to `require('yargs-parser')(args, opts={})`.
+
+**returns:**
+
+* `argv`: an object representing the parsed value of `args`
+  * `key/value`: key value pairs for each argument and their aliases.
+  * `_`: an array representing the positional arguments.
+* `error`: populated with an error object if an exception occurred during parsing.
+* `aliases`: the inferred list of aliases built by combining lists in `opts.alias`.
+* `newAliases`: any new aliases added via camel-case expansion.
+* `configuration`: the configuration loaded from the `yargs` stanza in package.json.
+
+<a name="configuration"></a>
+### Configuration
+
+The yargs-parser applies several automated transformations on the keys provided
+in `args`. These features can be turned on and off using the `configuration` field
+of `opts`.
+
+```js
+var parsed = parser(['--no-dice'], {
+  configuration: {
+    'boolean-negation': false
+  }
+})
+```
+
+### short option groups
+
+* default: `true`.
+* key: `short-option-groups`.
+
+Should a group of short-options be treated as boolean flags?
+
+```sh
+node example.js -abc
+{ _: [], a: true, b: true, c: true }
+```
+
+_if disabled:_
+
+```sh
+node example.js -abc
+{ _: [], abc: true }
+```
+
+### camel-case expansion
+
+* default: `true`.
+* key: `camel-case-expansion`.
+
+Should hyphenated arguments be expanded into camel-case aliases?
+
+```sh
+node example.js --foo-bar
+{ _: [], 'foo-bar': true, fooBar: true }
+```
+
+_if disabled:_
+
+```sh
+node example.js --foo-bar
+{ _: [], 'foo-bar': true }
+```
+
+### dot-notation
+
+* default: `true`
+* key: `dot-notation`
+
+Should keys that contain `.` be treated as objects?
+
+```sh
+node example.js --foo.bar
+{ _: [], foo: { bar: true } }
+```
+
+_if disabled:_
+
+```sh
+node example.js --foo.bar
+{ _: [], "foo.bar": true }
+```
+
+### parse numbers
+
+* default: `true`
+* key: 'parse-numbers'
+
+Should keys that look like numbers be treated as such?
+
+```sh
+node example.js --foo=99.3
+{ _: [], foo: 99.3 }
+```
+
+_if disabled:_
+
+```sh
+node example.js --foo=99.3
+{ _: [], foo: "99.3" }
+```
+
+### boolean negation
+
+* default: `true`
+* key: 'boolean-negation'
+
+Should variables prefixed with `--no` be treated as negations?
+
+```sh
+node example.js --no-foo
+{ _: [], foo: false }
+```
+
+_if disabled:_
+
+```sh
+node example.js --no-foo
+{ _: [], "no-foo": true }
+```
