The unfinished v0.31 of RAIL (21-jun-1988) includes the executables to create your own test text adventure, as well as the interpreter and an example test adventure to explore!
However, please read the new text instructions (readme.txt) which have been included to try and explain how to use the various executables. There is also a demo text game which was being created by Paul Coppins as a rigorous test of what RAIL could produce. Do not play this example game if you are easily offended!
