<!--
Joystick binding definitions.

This file is included by preferences.xml, and uses the context of its
inclusion point; that means that you need to prepend "/input/joysticks"
to all property names.

This file defines primary flight-control bindings for a simple
three-axis, three-button joystick, as follow:

  axis 0 (left-right): aileron
  axis 1 (forward-backward): elevator
  axis 2 (slider): throttle
  button 0 (trigger): brakes
  button 1: trim up
  button 2: trim down

If you have a more sophisticated joystick, there might be more axes
available; on my joystick, axis 2 is actually a twist axis (usually
for the rudder), while axis 3 is the throttle.  There are also two
axes for the hat switch, and several more buttons.
