Package byacc

http://invisible-island.net/byacc/byacc.html

This package provides a parser generator utility that reads a grammar
specification from a file and generates an LR(1) parser for it. The
parsers consist of a set of LALR(1) parsing tables and a driver
routine written in the C programming language. It has a public domain
license which includes the generated C.

If you are going to do development on your system, you will want to install
this package.
