Thanks to the various replies. I particularly like the INIT{@ARGV=<@ARGV>} one, and the one reminding about spaces in paths- they dovetail nicely. "for %f in ..." answer is a good one to remember as well.

These particular hosts are somewhat clamped down, so while I do use cygwin on my development machine, and install CPAN modules, I can't on those hosts, nor can I easily share folders/remote mount drives between my dev environment and theirs.
