description general-purpose parser generator
long_description \
Bison is a general-purpose parser generator that converts a grammar \
description for an LALR context-free grammar into a C program to \
parse 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.
