Re: Free ray tracing program

["Bob Sciamanda" <trebor@velocity.net>]

The files "Disk1.EXE" and "Disk2.EXE"  (in  the folder "Zipped_Version")
are self-extracting, zipped versions of the setup files "DISK_1" and
"DISK_2"  (in the folder "SnellTrace") for the Snell Trace ray-tracing
program.

Note: These setup programs will NOT work on Win3.x, only on Win95.  If
there is a need, I can re-do them so that Win 3.1 will run them.
