The copyright statement in the source (in main.c) of crafty 11.19 (it
may be different in different versions) states:
"Crafty, copyrighted 1996 by Robert M. Hyatt, Ph.D., Associate
Professor of Computer and Information Sciences, University of Alabama at
Birmingham."
"All rights reserved. No part of this program may be reproduced in
any form or by any means, for any commercial (for profit/sale) reasons. This
program may be freely distributed, used, and modified, so long as such use does
not in any way result in the sale of all or any part of the source, the
executables, or other distributed materials that are a part of this package."
The last sentence waives some rights Dr. Hyatt would otherwise have
under copyright law to control redistribution and modification of his work. I
am not sure Dr. Hyatt ever had any rights to control use but if he did this
clause waives them.
