This project is part of the GNU Project.

Bison is a general-purpose parser generator that converts an
annotated context-free grammar into an LALR(1), LR(1), or
GLR parser for that grammar.  Once you are proficient with
Bison, you can use it to develop a wide range of language parsers, from those
used in simple desk calculators to complex programming languages.

Bison is upward compatible with Yacc: all properly-written Yacc grammars
ought to work with Bison with no change.  Anyone familiar with Yacc
should be able to use Bison with little trouble.
