Re: [Discuss-gnuradio] Documentation generation using Sphinx

Just to clarify, I'm not suggesting we get rid of the Doxygen
documentation.  I think it documents the C++ side of things really
well.  What I'm suggesting is that we have two sets of documentation.
Doxygen-generated docs for the C++ stuff,  and sphinx-generated docs
for the python interface.

At the moment the subheaders are coming from the \ingroup tag
indirectly, in that I use that them to generate the initial
documentation, but it won't update automatically if they are changed.
I think automating the documentation generation to the level where
these would update automatically would complicate things more than it
would help.

I'll continue extending and tidying up the documentation and let you
know when it's at a more presentable point.
