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.
