Per my comment on patch 1, we can actually do this in python

#!/usr/bin/python
# -*- coding: utf-8 -*-

from libvirt_sandbox.image import cli
import sys

if __name__ == '__main__':
   sys.exit(cli.main())


which nicely avoids the need to have a .in file text
substitution.

I'm thinking these will be best in libvirt-sandbox/image/sources/Source.py
so we get a python import module of 'libvirt_sandbox.image.sources.Source"
