code checker using pep8 and pyflakes

 Flake8 is a wrapper around PyFlakes, pep8, and Ned's McCabe script. Flake8
 runs all tools by launching the single 'flake8' script, but ignores pep8 and
 PyFlakes extended options and just uses defaults. It displays the warnings in
 a per-file, merged output.
 .
 This package provides Python 2 module bindings only.
