-Manifold pressure instrument. This is not a stock C172 item and is usually
-not found on rentals. 
-
-October 2000 by John Check, <j4strngs@rockfish.net>
-________________________________________________________________________________
-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.
