"""
A simple setup.py file for building and publishing the website. 

Usage:
    python setup.py build

       This will regenerate the website from the current checkout

    python setup.py publish [--skip-build]

       This will upload the website to the server, building it beforehand
       unless the ``--skip-build`` option is used.

Note that this is *NOT* a valid python package, we just use setuptools 
facilities to ensure that all software we need is actually present.
