I downloaded it, just to have a poke around. It doesn't build very
easily, if at all. The best way I can describe the source is that it is
dry reading. Not much interesting commentary. Very big source files,
with very long functions and huge case statements is how I would
characterise it. I suspect it's reasonably well written but not very
extensible in nature. I don't think this is going to set the world on
fire anytime soon.
