In other words, my only complaint is that this Apple convention is not more easily discoverable. Or perhaps that the expert author of the book I was reading (this was back in the day) didn't feel the need to share it with his readers.

Its a standard thing to do in C. You generally use a prefix of 2-4 characters from your project name.
