## bison-3.2 – GNU parser generator

## Description

    "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.

    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.  You
    need to be fluent in C programming in order to use Bison.
