7 * nearly all joystick functions can be regarded as obsolete,
8 * as Linux (2.1.x) now supports extended joysticks
9 * with a completely new joystick driver interface
10 * new driver's docu says:
11 * "For backward compatibility the old interface is still included,
12 * but will be dropped in the future."
13 * Thus we should implement the new interface and at most keep the old
14 * routines for backward compatibility.
20 * 01/2000 added support for new joystick driver
