While you're at it, check out PCCTS, which generates LL(k)
recursive-descent parsers. In theory it is not as powerful as LALR(k)
generators, but in practice it *usually* makes up for it with
predicates. Plus, recursive-descent is SOOOO easy to debug. You can
start at http://www.empathy.com/pccts, which will piont you back to
the Parr Research PCCTS page and other places.
