Kay--
That's where it (starting with 0.5b2; 0.5b1 is in the
antlr.org file sharing section) will go--I have been
too busy with work to finish getting the sourceforge
project set up. I had hoped to manage that this
weekend--it was supposed to be a 4 day weekend, after
all--but spent too much time getting a critical
presentation together instead.
Cheers!
