+        Return a list of action instances for a particular publish.
+        This method is called each time a user clicks a publish somewhere in the UI.
+        The data returned from this hook will be used to populate the actions menu for a publish.
+
+        The mapping between Publish types and actions are kept in a different place
+        (in the configuration) so at the point when this hook is called, the loader app
+        has already established *which* actions are appropriate for this object.
+
+        The hook should return at least one action for each item passed in via the
+        actions parameter.
+
+        This method needs to return detailed data for those actions, in the form of a list
+        of dictionaries, each with name, params, caption and description keys.
+
+        Because you are operating on a particular publish, you may tailor the output
+        (caption, tooltip etc) to contain custom information suitable for this publish.
+
+        The ui_area parameter is a string and indicates where the publish is to be shown.
+        - If it will be shown in the main browsing area, "main" is passed.
+        - If it will be shown in the details area, "details" is passed.
+        - If it will be shown in the history area, "history" is passed.
+
+        Please note that it is perfectly possible to create more than one action "instance" for
+        an action! You can for example do scene introspection - if the action passed in
+        is "character_attachment" you may for example scan the scene, figure out all the nodes
+        where this object can be attached and return a list of action instances:
+        "attach to left hand", "attach to right hand" etc. In this case, when more than
+        one object is returned for an action, use the params key to pass additional
+        data into the run_action hook.
