This demo uses a shell script as a launcher.
Edit it and you will notice it checks if there are some specific
files at some specific place on your disc.

Checking for files this way is completly dumb and can fail... as you see :)

It's completly irrelevant with Warp3D version emulated by MorphOS.
All these checks should be done inside the demo executable, using
standard OpenLibrary() call. There is no other system compliant way.
