bison 3.6.3 Yacc-compatible parser generator

This is a GNU package.

GNU Bison is a general-purpose parser generator. It can build a deterministic or generalized LR parser from an annotated, context-free grammar. It is versatile enough to have many applications, from parsers for simple tools through complex programming languages.

Bison also provides an implementation of yacc, as specified by POSIX.
