@mvidner I sacrificed a scapegoat before commiting this sin of a non-descriptive boolean parameter, but apparently it didn't help ;-)

It's not exactly a verbosity, it controls whether the final status of the action is printed. That makes sense if the action code doeasn't print any other output. This is true for all actions except `compile`, which emits status messages for all files it compiles whit their own statuses.

I'll fix that at some point after @jreidinger is done with all his changes related to restructuring.
