mimetypes.py:405: No global (sys) found

This is inside usage() which presumably should only be used internally.
sys is imported if name == 'main'. So the problem can only be triggered if usage() is called by external source.

Possible fixes are: sys could be locally imported in usage() sys could be imported at the module scope usage could be made _usage() to denote it's private

Neal, I'll propose another fix, but I don't know what pychecker would say. ;-) I'd like to move the definition of usage() into the if name == "main" block, in which case the problem goes away since there wouldn't be a usage() unless sys has been imported. I'll check it in that way. ;-)
