brozzler/vagrant/vagrant-brozzler-new-site.py

#!/usr/bin/env python
'''
vagrant-brozzler-new-site.py - runs brozzler-new-site inside the vagrant vm to
queue a site for your vagrant brozzler deployment.

Fills in the --proxy option automatically. Some other options are passed
through.

This is a standalone script with no dependencies other than python, and should
work with python 2.7 or python 3.2+. The only reason it's not a bash script is
so we can use the argparse library.
