Thanks, I'm interested.

I don't know much about that, but doesn't Ruby just do the right thing?  I'd guess that if you use 
back ticks in perl it would get the right interpreter on both Linux and Windows.  Although you don't 
seem to use any of that in your script.

Do the files in the zip have paths?  If not I'm not sure why you have 2 loops to figure out the 
version number.

In perl I'd have made each path a hash key and incremented the value each time.  Then you shouldn't 
need to check whether something exists--if it's in the hash you use the value as the version number 
and if it isn't you use it as is.

I didn't look at perl's zip library so I'd have used unzip to get the list of files and do the 
unzipping, so you're more elegant there.

And looking a little closer, would unzip -B have done what you need?
