Yet Another Compiler Compiler
     
         (yacc) The {LALR} {parser generator} found on
        most {Unix} systems.  Also, the language used to describe the
        {syntax} of another language to yacc (the program).
     
        Implementations: {ayacc}, {YAY}, {perln-byacc},

        Programming", Simon Peyton-Jones, Software Prac & Exp
        15:807-820 (1985).  Mentions also a BCPL implementation.
     
        Yacc++ - 1990.  An {object-oriented} rewrite of yacc, supports
        {regular expression}s, produces an {LR1 grammar} parser.
