    (synopsis
     "GNU Bison, a Yacc-compatible parser generator")
    (description
     "Bison is a general-purpose parser generator that converts an
annotated context-free grammar into an LALR(1) or GLR parser for
that grammar.  Once you are proficient with Bison, you can 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 or C++ programming in order
to use Bison.")
