   bison 3.7.4 (parser generator similar to yacc)

   GNU "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.

   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.
