Python code checking using pyflakes, pycodestyle, and mccabe
Description
Flake8 is a wrapper around PyFlakes, pycodestyle, and Ned's McCabe
script. It runs all the tools by launching the single flake8 script,
and displays the warnings in a per-file, merged output.
It also adds a few features: files that contain "# flake8: noqa" are
skipped, lines that contain a "# noqa" comment at the end will not
issue warnings, Git and Mercurial hooks are included, a McCabe
complexity checker is included, and it is extendable through
flake8.extension entry points.
