You've told half of the story, but what about the other half? I am
interested in how you create that \usr\lib\cdspace file. I don't know
of any smart way to get this done except by a line of C code:

	main() {printf("cd ");}

Is there editor/word processor out there that can kill CR+LF?

BTW, "cd>>\tmp\cdspace.bat" was neat. I didn't know you can do it this way
before.
