SYNOPSIS
Berkeley Yacc (byacc)
is generally conceded to be the best yacc variant available.
In contrast to bison,
it is written to avoid dependencies upon a particular compiler.
HISTORY
Byacc was written around 1990 by Robert Corbett who is the original
author of bison.
Originally written in K&R C, I have modified it to conform to ANSI C,
and made other improvements.
See the changelog for details.
