Ladies and gentlemen of the jury, I'm just a caveman. I fell on some ice and later got thawed out by some of your scientists. Your world frightens and confuses me! Sometimes the honking horns of your traffic make me want to get out of my BMW.. and run off into the hills, or wherever.. Sometimes when I get a message on my fax machine, I wonder: "Did little demons get inside and type it?" I don't know! My primitive mind can't grasp these concepts. But there is one thing I do know - when a man like my client slips and falls on a sidewalk in front of a public library, then he is entitled to no less than two million in compensatory damages, and two million in punitive damages. Thank you.

Except according to this wikipedia entry it's called src/source because it was forked of the GoldSrc engine and they just shorten the name of the new dir to Src.

Close. The Half-Life code was maintained in the "Src" tree up until release, and then forked it off into "GoldSrc" after Half-Life went gold. "Src" then went on to mutate into the Half-Life 2 engine, and "Source". So "GoldSrc" actually came AFTER "Src", because "Src" has basically always been around.
