Parser.300 source code reconstructed

[John Cowan <jcowan@reutershealth.com>]

At http://www.ccil.org/~cowan/parser-3.0.00.tar.gz is my best
attempt at reconstructing the source code for my parser
for grammar.300 (the final version).

There are almost certainly bugs.  Please try to fix them.
Thanks.
