...except that we haven't used it that way.  Instead, we make a whole
bunch of smaller, partially structured document silos.

Well, not inventing the wheel was kind of the motivation behind much of
this effort; I got kind of worried watching us trying to cobble more
functionality into our existing house-of-cards documentation system.

Sphinx is a well-established, heavily used, and well supported system;
using it would not be an exercise in wheel reinvention.  As far as I can
tell, it does everything we need (with some open questions about table
support), lets us drop the whole DocBook toolchain dependency, and move to
a much better-supported setup than we have now.  Plus we get much nicer
output, index generation, cross-references between documents, and the
ability to write documents in a lightweight markup language.  Seems like a
win.

I assume you're referring to gtk-doc?  It's web page
(http://www.gtk.org/gtk-doc/) starts by noting that it's "a bit awkward to
setup and use"; they recommend looking at Doxygen instead.  So I guess I'm
not really sure what it offers that merits throwing another option into
the mix now?  What am I missing?

Thanks,
