     (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.")
