Add a command to run lint tools such as Python -3, pep8, pyflakes, pychecker, pylint. I think this should not be a subcommand of test. The idea comes from buildutils (http://pypi.python.org/pypi/buildutils/).
There has been a lengthy discussion on the fellowship-of-the-packaging ML about what should or should not be a command. One side argues that distutils commands should only concern themselves with packaging, distributing and installing, the other side defends that distutils, like a makefile, is a place to put useful functionality for developers. test is in a gray area, lint even more. I’ll ask for feedback on this later.
