+King KR-87 ADF radio instrument.
+John Check <j4strngs@rockfish.net>
+July 2002
+
+This is an instrument configuration file for the open-source flight
+simulator FlightGear (www.flightgear.org).  The file is an XML-encoded
+FlightGear property list defining the instrument's layers and actions.
+
+Each instrument is composed of layers stacked on top of each other.
+A layer may be a texture (with transparent parts to show the layers
+underneath), text, or a special layer that switches between two
+others (say, to turn an indicator light on or off).  Each layer can
+move independently in proportion to a property value, and text
+can be generated from property values as well: all of the layer's
+movements are defined as transformations.
+
+Actions are hotspots on the instrument that will respond to a mouse
+click.  Actions always modify the values of properties, either by
+adjusting them, toggling them, or swaping them with other
+properties' values.
