Try wsmr-simtel20.army.mil for the Pretty-Printer parser.

BIG DITTOs for that code.  It is extremely generic.  I believe we've now
compiled it under Meridian, VAX Ada, and perhaps Janus.  It's clean (or at
least as clean as any parser can be.)

A warning:  The Pretty-Printer is LARGE and uses several different files found
in the Simtel-20 Repository.  Since Simtel-20 is a DEC 20, the directory
structure are not what DOS/UNIX/VMS/etc.-types may be used to.
