No, but the license is clear (and similar to GPL): /* ******************************************************************************* * * * Crafty, copyright 1996-2001 by Robert M.

Such permission will include the * * requirement that the program be entered under the name "Crafty" so that * * the program's ancestry will be known. * * * * Copies of the source must contain the original copyright notice intact. * * * * Any changes made to this software must also be made public to comply with * * the original intent of this software distribution project.
