/*
 * $Log:	main.c,v $
 * Revision 3.0  88/03/10  12:07:32  hale
 * Added save games, a few changes to the I/O,
 * added load and clear options.  Not thouroughly tested, though, and
 * I think a few bugs are in the load code.  A library of sample problems
 * has been started and saved with the working directory.
 * 
 * Revision 1.4  88/02/19  13:48:56  hale
 * Added io changes for loading games.
 * Load game is cleaned up.  Variable board
 * sizes and formats available in save game
 * as well as printed comments.
 * 
 * Revision 1.3  88/02/14  00:23:06  hale
 * Added load file option during game to restore game to starting
 * state.  Also, clear board operation.  Restoring game puts current
 * player in sync.  With the demo mode, this is invaluable.
 * 
 * Revision 1.2  88/02/13  12:49:59  hale
 * modified entry to have load option work and opponnents name is loaded
 * properly.
