longDescription = ''
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.
