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.
