I've heard that there are several PostScript-compatible interpreters available
in the public domain. I've seen one, in C for Unix, from Europe, but the
source I have is about two years old, and I imagine there has been an update.
Another was supposedly developed at the University of Tokyo, written in
Microsoft C for the PC. I saw a reference to it in some programmer magazine,
but for the life of me can't find the magazine again. Has anyone heard of this
one? Or know about another source of a PostScript-compatible interpreter?
