Now I can't find it!!!! [aka where was that script??]

I was looking for a script that takes all the contacts from the Address Book that are NOT currently assigned to any group and makes a new group with all these contacts in them. I didn’t see the need for something like this, but several weeks later, I found I really needed something like this but can’t find the site where I saw it [I think I saw the initial link on] and have been searching all over. Any help would be appreciated.
