Notebooks in Sphinx?

Notebooks in Sphinx?

Converting the notebooks to ReST with nbconvert, then using sphinx on the
.rst files gives a pretty decent effect, except that the title levels are
off a little.

I need to look into hosting for the notebooks, maybe on MS Azure.  In the
meantime, I prefer the HTML made by Sphinx to the HTML made by nbconvert
directly.  It has index and cross refs and the code blocks scroll
horizontally which is crucial for wide Joy traces.  And Garamond.  God
bless Garamond.

For the Sphinx docs I'm going to edit the notebook ReST files by hand,
diverging from the originals.
