Comment #6 on issue 1061 by pekka.klarck: Support for `libdoc` to show
library/resource information on console
http://code.google.com/p/robotframework/issues/detail?id=1061
1) Thanks for reminder. I was planning to restrict `handles` but forgot.
Another problem with the current implementation is that it can mask bugs in
the code (if those bugs end up raising TypeError or AttributeError). I've
also considered adding a separate classmethod for validating args for
commands so that all validation could be done in Libdoc.validate.
2) I was planning to write the usage like this:
robot.libdoc [options] lib_or_res output_file
robot.libdoc [options] list [patterns]
robot.libdoc [options] show [names]
robot.libdoc [options] version
