SUMMARY = "GNU Project parser generator (yacc replacement)."
DESCRIPTION = "Bison is a general-purpose parser generator that converts an annotated context-free grammar into \
an LALR(1) or GLR parser for that grammar.  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."
