    (description
     "Bison is a general-purpose parser generator.  It can build a
deterministic LR or generalized LR parser from an annotated, context- free
grammar.  It is versatile enough to have a wide variety of applications, from
parsers for simple tools up to parsers for complex programming languages.")
