+		The Itead Joystick shield supports analog X/Y position and up to 5
+		buttons.  Some of these buttons may conflict with other resources
+		(Button F, for example, conflicts with the default USART1 pin usage).
+		Selecting this option will return the number of buttons to the
+		minimal set:  SELECT (joystick down), FIRE (BUTTON B), and JUMP
+		(BUTTON A).
