+
+   "Bison" is a general-purpose parser generator that converts a
+grammar description for an LALR(1) context-free grammar into a C
+program to parse that grammar.  Once you are proficient with Bison, you
+may 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 programming in order to use Bison or to understand this
+manual.
