Robert J. Sawyer, a "Hugo and Nebula Award-winning Canadian science-fiction writer", loves and uses this DOS software -- according to his site, so does Anne Rice & George R.R. Martin. So Sawyer packaged it with the DOSBox-X emulator and a ton of documentation in a Zip file for download. To run it by default, place the WS folder in C:\, & run C:\WS\DOSBox-X\DOSBox-X.exe. The File menu has the exit command, and exit closes the emulator. Ran it in my Win11 VM and InstallWatch Pro did not record any changes to anything. If you're curious, like I was, give it a look.
