flakes
Uses the pyflakes library to find lint in all modules.
The flakes module is accessible via the buildutils.command module.
From the pyflakes project page:
Pyflakes is a simple program which checks Python source files for errors. It is similar to PyChecker in scope, but differs in that it does not execute the modules to check them. This is both safer and faster, although it does not perform as many checks. Unlike PyLint, Pyflakes checks only for logical errors in programs; it does not perform any checks on style.
