What is GNU bison ?

bison is the GNU replacement for the yacc (yet another compiler compiler) 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 don't need this unless you're a software developer.

See 'man bison' for further details.
