bison is the GNU replacement for yacc (yet another compiler compiler) and should be upwardly compatible with input files designed for yacc.
bison-1.35: description + notes
bison has many extensions and improvements compared to the traditional yacc and its use for software development projects that need to generate programming language grammar parsers is highly recommended.
Many GNU and freeware packages use
bison -y(bison withyacccompatibility mode) in their building process, so this package may be handy for this purpose as well.The Bison home page has more information.
