"""Builds the website from django templates and language files.

Uses the django template system to create static files for the website. This
allows easy inclusion of common content, but removes the need for (e.g.) PHP
includes that don't really do anything dynamic.

You can build the website for all languages, by doing:
$ python build-website.py

This requires the python-django package on debian.
