We don't actually add any section 3 man pages, but be prepared.

Hawkmoth [1] is a minimalistic Sphinx C Domain autodoc directive
extension to incorporate formatted C source code comments into Sphinx
based documentation, by yours truly.
This adds libnotmuch(3) man page to incorporate API documentation
using the extension. The naming is intentional to not conflict with
the Doxygen based man page, for now.
Hawkmoth has a few advantages over Doxygen. It directly integrates
with Sphinx, and allows reStructuredText syntax in the documentation
comments. It's simple and minimal, without the overlap of Doxygen and
Sphinx.
Of course, there are some disadvantages as well. Hawkmoth is a project
very much in the larval stage. It's not even packaged yet. It
undoubtedly has plenty of unexpected issues and bugs. It only has one
contributor to fix them. It only targets C documentation.
Hawkmoth C parsing is based on Clang Python Bindings, but then Doxygen
also depends on Clang.
On Debian, the minimum dependencies are:
* python-clang-3.8
* libclang-3.8-dev
* libclang1-3.8
Unfortunately python-clang seems to be for Python 2 only, so you'll
need to use Python 2 based Sphinx as well. (To be investigated.)
As can be seen from the size of this patch, the simplicity of Hawkmoth
makes it a compelling alternative for Sphinx based C API
documentation.

Document notmuch_database_create() using as much bling as
possible. This is pretty nice in the output, but probably too
excessive in source code. Nonetheless, it's an example of what could
be done.
