;;; Commentary:

;; This is a thin wrapper around python-pylint
;; (https://gist.github.com/302848) to run flake8.

;; Sometimes I want to run pylint and sometimes flake8. This simple
;; wrapper just re-uses python-pylint's compilation mode and
;; configures it to use flake8 and parses it's output.
