+ Revision 1.7 2004/09/30 22:32:04 savage
+ Updated with slightly different header comments
+
+ Revision 1.6 2004/09/12 21:52:58 savage
+ Slight changes to fix some issues with the sdl classes.
+
+ Revision 1.5 2004/05/10 21:11:49 savage
+ changes required to help get SoAoS off the ground.
+
+ Revision 1.4 2004/05/03 22:38:40 savage
+ Added the ability to enable or disable certain inputs @ runtime. Basically it just does not call UpdateInput if Enabled = false.
+ Can also disable and enable input devices via the InputManager.
+
+ Revision 1.3 2004/04/28 21:27:01 savage
+ Updated Joystick code and event handlers. Needs testing...
+
+ Revision 1.2 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.1 2004/02/05 00:08:20 savage
+ Module 1.0 release
