<!--
Mouse binding definitions.

This is a independent configuration file: it is not part of the main
FlightGear property tree.

Currently, Glut supports only one mouse, but the configuration format
is designed to support additional mice in the future if possible.  The
current mode for each mouse is held in the
/devices/status/mice/mouse[n]/mode property.
