File for adding buildout omelette paths to virtualenv in vagrant for use by PyCharm. With this file, PyCharm can use the omelette packages from the vagrant remote interpreter. Usage: tweak paths in file if necessary, make it executable and put it in /usr/local/bin. Then run omelette2venv.py.

omelette2venv.py

#!/usr/bin/env python
import os

def main(omelette_dir='/srv/parts/omelette'):

    Workaround to enable PyCharm to get access to the project modules.

    Requirements:
    - omelette directory created by buildout
    - a virtualenv with the system packages named /home/vagrant/venv

    You can then use /home/vagrant/venv/bin/python as your project's
    interpreter in PyCharm.
