  45     (description
  46      "Bison is a general-purpose parser generator that converts an
  47 annotated context-free grammar into an LALR(1) or GLR parser for
  48 that grammar.  Once you are proficient with Bison, you can use
  49 it to develop a wide range of language parsers, from those used
  50 in simple desk calculators to complex programming languages.
  51
  52 Bison is upward compatible with Yacc: all properly-written Yacc
  53 grammars ought to work with Bison with no change.  Anyone
  54 familiar with Yacc should be able to use Bison with little
  55 trouble.  You need to be fluent in C or C++ programming in order
  56 to use Bison.")
