Change Developer Name

I'm 15 and am using my dad's old computer for developing iPhone apps. He set me up with an account on his computer called "Developer". I noticed that in Xcode for each source file a comment section is added with copyright info. I figured out how to change the company identifier to a cool name I thought of, but I'd like to know how to change the developer name too, because right now it just reads "Developer" and I want it to put my name there. Also, I don't want to just change it manually, because that would get annoying.
