    description         Localization support for Bison-generated parsers
    long_description    The Bison parser generator provides \
                        translations for its parser diagnostics. \
                        Programs that contain Bison-generated parsers \
                        can use these translations to generate \
                        localized error messages.

    description         The Yacc-compatible Parser Generator
    long_description    Bison is a general-purpose parser generator \
                        that converts an annotated context-free \
                        grammar into a deterministic LR or generalized \
                        LR (GLR) parser employing LALR(1) parser \
                        tables. As an experimental feature, Bison can \
                        also generate IELR(1) or canonical LR(1) \
                        parser tables. 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.
