Works for me. Should resolve the issues mentioned in #47.

After long last, i've found a solution that works and doesn't even depend on pre-commit (screw that). Just add a pre-commit file to .git/hooks with the following content:

#!/bin/bash

cd backend
unset GIT_DIR
git diff  --cached --name-only --relative | xargs prospector --uses django

Prospector must be installed, so either the virtualenv must be activated during commit, or it mus be installed system-wide.
