Dear Adriaan,
I suggest we make the script, or another one written from scratch, suitable for Linux, MinGW and other targets.
I like that idea. That's what we do for my own code. We run the same build script (Makefile, actually) on all platforms and it figures everything out for you. I'll look at your build.command and see if I can figure out how to adapt it to Linux and MinGW.
Yours, Kevan
