This is the 5.1 PL08 version of Unix DND, ported by Chuck Cranor.

ANSI C source code.  Data files are included.  To compile, type "make".  To
run, type "./udd".

This version was originally contributed by Chuck Cranor but later fixed to 
compile on modern systems by Amardeep Chana.  See VERSION.txt.

The pfile had to be wiped in this version, so I am leaving 5.1.8 in the
historical archives to preserve that file (although a tar archive of 5.1.8 is 
in the rancourt.tripod.com website mirror).
