 * DataBase -- A very simple database program that	*

 * 							*
 * Usage:						*
 *	database [-S<file>]				*
 *							*
 *	-S<file>	Specify save file for 		*
 *			debugging purposes		*
 *							*
 *	-P<file>	Specify playback file for	*
 *			debugging or demonstration.	*
 *							*
 *		Program will ask you for a name.	*
 *		Enter the name; it will tell you if	*
 *		it is the list.				*
 *							*
 *		A blank name terminates the program.	*
