* A Reversi (or sometimes called Othello) game

*
* Created 1997 by Mario Weilguni <mweilguni@sime.com>. This file
* is ported from Mats Luthman's <Mats.Luthman@sylog.se> JAVA applet.
* Many thanks to Mr. Luthman who has allowed me to put this port
* under the GNU GPL. Without his wonderful game engine kreversi
* would be just another of those Reversi programs a five year old
* child could beat easily. But with it it's a worthy opponent!
*
* If you are interested on the JAVA applet of Mr. Luthman take a
* look at http://www.sylog.se/~mats/
