    (description
     "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 @command{yacc}, as specified by POSIX.")
