Documentation for the Bison parser generator

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

 This package contains the PDF and Info documentation for Bison.
