From the descriptions of cloning given early on in this thread, the necessity of acquiring additional software (if not skills) and the fact that Pogue mentions it nowhere in his manual (as far as I can tell so far, because it's not indexed), I suspect that it isn't either easy or comical.
My copy is indexed (extensively so), pages 885-909.
From the colophon: "The author composed the index, entry by entry, using a highly tweaked FileMaker database and a clever Perl script that converted FileMaker's output into a fully formatted index."
Perhaps Sir Grelber just hasn't gotten that far (yet).
