I'm not aware of any desktop Linux distro that doesn't have perl,
either. I certainly wouldn't want to use any distro that skipped
something as fundamental as perl. No, I was thinking more along the
lines of embedded Linux environments like DD-WRT and the like. I want
my script to run with absolute minimal requirements.
Mostly, though, I just object to using perl this time because then I
would have to keep arguing with myself "why don't I just do the entire
thing in perl" :-D
