Util for generating a Komodo project file that works with virtualenv

virtualenv_komodo_project.py

"""
A sample utility for customizing virtualenv creation based
on the postmkvirtualenv hook provided by virtualenvwrapper.

This script will generate a Komodo project file suitable for
use in Komodo Edit (and presumably Komodo IDE). The project preferences
are automatically customized so that the Python path contains the
new virtualenv's site-packages directory.
(Project Properties -> Languages -> Python in the GUI)

Since Komodo keeps track of which open files belong to which projects,
you can keep multiple projects open and the autocomplete should work
appropriately for each file (appropriately meaning using the correct
virtualenv paths)

This tool also creates a blank default project directory to go with
the virtualenv. An alternative could be to run django-admin startproject
at this point.

This tool can be integrated with virtualenvwrapper by dropping something
like the following into your postmkvirtualenv file:

    python /path/to/this/file.py
