If you're interested in Treetop, here is a video of it being presented at a
conference (has a nice live code section). I tried playing with it a while
back, and with a lot of effort was able to get past the basics. But I think
the wall I ultimately ran into has to do with understanding what to do with
it once parsed. Maybe I'll try to get into a compiler class next semester.
Also the docs could be a lot better.
