%description
Bison is a general purpose parser generator which converts a grammar
description for an LALR(1) context-free grammar into a C program to parse
that grammar.  Bison can be used to develop a wide range of language
parsers, from ones used in simple desk calculators to complex programming
languages.  Bison is upwardly compatible with Yacc, so any correctly
written Yacc grammar should work with Bison without any changes.  If
you know Yacc, you shouldn't have any trouble using Bison. You do need
to be very proficient in C programming to be able to use Bison).  Bison 
is only needed on systems that are used for development.

If your system will be used for C development, you should install Bison
since it is used to build many C programs.
