-      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.
