mk-build-deps build failure (usage printout)

Fails to build with printing out help for mk-build-deps:

(base) [sm@fedora-mbp docker-deb-builder]$ ./build -i docker-deb-builder:20.04 -o output ./sources/bmxlib-libmxf

Do you have any ideas on what should I check? I thought about the dependencies list but it seems to be fine.
Thanks!

Hi @sxiii,
Sorry for delay replying. Does the source code of bmxlib-libmxf have debian/control file and other packaging files that are required by the packaging tools https://wiki.debian.org/Packaging/Intro

[sxiii]

That's OK @tsaarni -- Originally it hadn't, but I've written the required files myself when I was trying to make it work :)

I quickly looked at the mk-build-deps script from Debian devscripts package and it seemed to me that the usage could be printed if debian/control was missing, or maybe it could be some typo in the deb packaging files. Other than that, I don't have ideas...
