 The HTML documentation is generated using [Sphinx](https://pypi.python.org/pypi/Sphinx). To build, ensure that Sphinx is installed (``pip install sphinx``), then navigate to [the docs folder](/docs) and run ``make html``. More interestingly, I'm using Sphinx's [doctest extension](http://sphinx-doc.org/ext/doctest.html) to run some simple automated tests. To use it, ensure Sphinx is installed and run ``make doctest`` from the docs directory.
