It used to be such a great thing when you would come across a Vignette CURL on a site that you didn't know or expect to be a customer site. Spotting CURLs in the wild was a sport!
@Charlie Wood once wrote a post explaining what the components of a CURL meant.

Its been awhile since I've spotted a wild CURL. Anyone know of remaining live sites?
I must confess to being the originator of that CURL format.
