Actually, I'm with Lele on this one. You can get practically 90% of the
SVN interface extracted with just a few regex. I demo'd this a long while
back with build/generator/extractor.py. It goofed on a few things, but
that was mostly due to non-standard formatting in the headers. After
fixing that up, there was one stray thought that svn_boolean_t was a
function, so extractor.py just punts on that.
Our header files are *very* regular. The simple reason is that we're a
single project. A full C preprocessor, or the complexity that is built
into SWIG, is there because it has to parse all kinds of headers. We have
the option to make our headers conform to our own parsing needs. That is
actually *very* handy, and can tremendously simplify the whole task.

Heh. I've been using the Python bindings for years. Literally.
But that said: I doubt that Ben was bashing the Python bindings in that
way. Instead, I think each of you were just overreacting and should have
stopped to take a breath :-)
