Eep!

Since it looks like davorg hasn't seen this yet, I guess I'll be the one to point this out.. don't use Matt's scripts, they're insecure and badly written. There's a good reason he and some other respected Perlmonks have been working hard on NMS, which is a nicely coded drop-in replacement which adheres to proper coding practices.

Have a look here is you don't just want to take my word for this, or SuperSearch for 'Matt's Script Archive'.

Don't try and debug Matt, use NMS. It's quicker, safer, and the right thing to do. Go on, you know you want to.
