URL Handler

Hi, I’ve heard about "URL Handler"s like “skype:SKYPENAME?add” will open up Skype on your Mac. I’ve heard also about putting something or other in the Info.plist file too.

Can anybody help me out and explain all of this to me, and how to set it up?

Ok, I just saw this site: http://www.cocoadev.com/index.pl?HowToRegisterURLHandler which made everything a bit more understandable. How could I convert this code to ASOC and use it?
