bison is the GNU replacement for the yacc (yet another compiler compiler). The standard Un*x parser generator.
bison is better than yacc, and it has an
option, '-y' to produce yacc
compatible output.
The reasons to use bison (over yacc) are the same as those for using flex (over lex): portability, universal availablity, speed, net support. Unlike flex which provides lexical analysis of regular expressions, bison generates parsers to handle more powerful context-free grammars.
Some details on the yacc/bison differences are available in the REFERENCES file included with the sources.
Most likely you need bison only if you're a software developer and engaged in developing tools which parse context free grammars.
See 'man bison' for further details.
