   Gray
      A parser generator written in Forth by Martin Anton Ertl
      <anton@mips.complang.tuwien.ac.at>.  Gray takes grammars in an
      extended BNF and produces executable Forth code for
      recursive descent parsers.  There is no special support for
      error handling.  Version 3 runs under Tile Forth Release 2
      by Mikael Patel.
