-// opengc.hxx -- define shared flight model parameters
+// opengc_data.hxx -- Define structure of OpenGC/FG interface parameters
+//
+// Version by J. Wojnaroski for interface to Open Glass Displays
+//
+// Modified 02/12/01 - Update engine structure for multi-engine models
+// - Added data preamble to id msg types
+//
+// Modified 01/23/02 - Converted portions of the Engine and Gear accesssors to properties
+// - Removed data from navigation functions. OpenGC provides own
+//
+// This file defines the class/structure of the UDP packet that sends
+// the simulation data created by FlightGear to the glass displays. It
+// is required to "sync" the data types contained in the packet
