I thought it was not used in racing, but you would shift into neutral, let off clutch, then push it back in to engage to the next gear...seems pointless to me if you're trying to go fast.
But I don't think thats what you're talking about.

Clutch in, shift into neutral, clutch out, rev up the motor to get the trans internals spinning to the appropriate revs matching the engine, clutch in, shift into gear, clutch out. It's a technique used in transmissions that do not have synchros where the speed of the engine and transmission internals needed to be closely matched on shifts so that you wouldn't grind going into gear.
There is an excellent article here (http://auto.howstuffworks.com/transmission.htm) that explains the internals of the manual transmission very well with simple diagrams and interactive illustrations. On page 3, there is a great explanation of what double clutching is. I highly recommend you read this article and especially page three if you want to know what double clutching really is, rather than listening to the various false information that so easily spreads throughout the forums. Page 4 explains synchros.
Anyone who truly understands what double clutching is would realize there is no legitimate purpose for doing it in a car that has a synchronized transmission (ie our cars), unless you're really that worried about wearing down the friction cones in the synchros. I've only once ever seen a friction cone go out, though (and of course it was in my car...).

Haha, that's awesome.
I prefer the shifting method where I put a brick on my gas pedal, then I put both feet on the dashboard, grab that shifter with both hands and yank it into the next gear no matter kind of sounds the transmission makes.
Takes a man to use this method though

clutch in, put RPMs at whatever speed, shift, and clutch out?
