I you want some help getting started, I've been learning both Treetop
and Dhaka for the last month or so and would be happy to help you get
started. (Not that I'm necessarily any good at them, but I've made
them work at least.) Ghost Wheel look nice, so I might try learning
that too. I can be found loitering on irc://irc.freenode.net/#rubyunix
