Hello,
Does anyone know of any tool/program/hack etc that given
a yacc file will extract the bnf grammar ???
I did start off with a bnf grammer but changed it while writing
the yacc stuff and have since lost the list of changes.
If any one has an idea's or knows where I can find something to
do the above I would like to here from you.
Thanks in advance.

[Berkeley yacc with the -v option puts the grammar without any of the
action code at the beginning of the listing file. I'd think it'd be
pretty easy to write a sed or awk script to extract that and change the
colons to ::= -John]
