That sounds really cool.

Well, that's the beauty of free software, isn't it. :-)
Seriously, though, I'm still working on the XHTML importer, but not as
much. The sourcegear people seem committed to 1.0 in the next few months,
and I'd like to help them get that done (and I really like playing with
gdb). But changing the vector implementation to the STL would be really
easy. All of our functions would just be wrappers around STL functions,
which would be pretty easy to code.
