We haven't decided yet. I'd like to make them available for other
hobbyists, but I'm not sure I want to give them away to my competitors if
I decide to write another book. We really haven't dug into the legality
(or enforcibility) of making them available for "non-commercial" use.
Since making them public is a one-way thing, we've decided to hold off
until we decide on a follow-up book.
