If you seriously want the legal right to control commercial usage,
you must follow the international copyright law in such matters.
Since you gave no copyright notice (which is required to say "copyright"
along with your name & year of publication), this is now public domain.

I rather like public domain offerings, but thought you might like to
know for future reference. Thanks for contributing!
