which_repos script

Hey Everyone, After a while I've managed to add quite a few other peoples repositories to my ports tree and it got to be a task trying to figure out which ones came from where and which ones were obsolete (no longer in any of the repos). So I wrote this perl script to figure it out for me and thought someone else might find it useful too. Also I included another really simple script to strip out the core ports from listorphans. Feel free to send me feedback. Nick
