usr/src/games/ddl/READ_ME

This directory contains:
        binaries for ``ddlrun'' and ``ddlcomp''
        Documentation for writing your own DDL program is in
                the "doc" directory.
        An example DDL game is in the "sample" directory.
        To compile a DDL program do:
                ddlcomp destination-file < source.ddl
        You then run the game with:
                   ddlrun destination-file
        DDL produces large-appearing files that are full of holes
        and should not be copied.
        Note: DDL source for "aardvark" is contained in ../aard.
