YACC help

[netnews]

This is a question that's been asked before no doubt, but I didn't
get to see the answer(s). So:

	Where can I find a good discussion of yacc? I don't mean an
exposition on the internals of yacc, but practical examples of how to
use it. Further, are there any PD versions floating about - I need to
port this to a PDP running RSX-11M (don't laugh, we have lex running so far).
