This script creates a virtual environment, uses pip to install your requirements, fixes up the environment to use the correct paths, creates links from /usr/local/bin to any scripts and then uses fpm to build a DEB/RPM.

Because you want to ship an entire virtual environment and not rely on system packages for python or python libraries.

For the moment, you need to install fpm (gem install fpm) and ensure it is on your PATH. Then clone this repository and run pypackage.py.
