Runs pyflakes & pep8.py on your Python files and a trailing whitespace
checker on all the rest. Keeps anal-retentive style nazis like me happy, and
should (in theory) make your code look nicer.
check.py
This will run checks on any added or modified files according to your vcs's
status command (git or svn at the moment).
check.py models.py tests/
This will run checks on models.py and any files found recursively in the
tests/ directory.
Best installed with pip or easy_install so you also get the pyflakes dependency.
