It shouldn't be strictly "public domain", either.  Aside from the fact that
the original Hack sources are no doubt copyrighted, placing a program in the
public domain means that one has given up all rights to it -- including the
right to prevent other people from trying to make a profit on it.  What you
should do is to place a copyright notice on it and a statement saying it can
be duplicated and used freely for noncommercial purposes.
