Oh heavens, I never even thought about that... the world was a much better
place when you actually needed to *claim copyright* rather than just have
it apply automatically on every stupid little doodle or comment.

I've heard from authorities I trust that under US law private citizens
can't "not copyright" something you write, even if you want it to go into
the Public Domain. I've also heard the opposite from experts I equally
trust.

So, let me say firstly that I wish the following code to be put into
the public domain, and if there is any reason why it has not been, I
hereby give everybody an unlimited, non-exclusive, transferable, free of
all charges and royalties, licence to use the following code in any way
they see fit, with no conditions attached except there is no warranty. You
don't even have to credit me. If you try to make a warranty claim against
me for this code, the licence is instantly revoked.

There. It probably won't stand up in a court of law, but I promise not to
sue if you promise the same.
