Documentation (PDF, ePub)

In ``sbt``, you can now run ``sphinx:generatePdf`` and ``sphinx:generateEpub``, which produce PDF and ePub versions of the documentation in the ``docs`` directory; authored in [reStructuredText](http://docutils.sourceforge.net/rst.html).

You will need to install [Sphinx](http://sphinx-doc.org/) (``easy_install -U Sphinx``), you will also need [LaTeX](http://www.latex-project.org/) or [MacTeX](http://tug.org/mactex/).
