The included file patches the MDL Zork sources for use by the Confusion MDL 
interpreter.

To use it, unpack the MDL sources into a directory such as mdlzork.
Then execute  the following commands
patch -d mdlzork < confusion_mdlzork.diff
mkdir mdlzork/MTRZORK
mkdir mdlzork/MDL

The directory is now set up.  To run ZORK the first time:
cd mdlzork
/path/to/mdli
<FLOAD "run.mud">

To run ZORK subsequent times (if you haven't changed the source)
cd mdlzork
/path/to/mdli -r MDL/MADADV.SAVE
