Installing sphinx and building docs

To install Sphinx, execute this from within any directory.

   sudo easy_install -U sphinx

To build the docs, change and then execute as follows.

   $ cd abjad/documentation/doc_sphinx

Then:

   $ make html

Sphinx runs for a while.

   sphinx-build -b html -d _build/doctrees   . _build/html
   Making output directory...

And then finishes.
