/*
+ * Revision 1.16 1998/08/22 14:49:55 curt
+ * Attempting to iron out seg faults and crashes.
+ * Did some shuffling to fix a initialization order problem between view
+ * position, scenery elevation.
+ *
+ * Revision 1.15 1998/07/30 23:44:36 curt
+ * Beginning to add support for multiple flight models.
+ *
+ * Revision 1.14 1998/07/12 03:08:27 curt
+ * Added fgFlightModelSetAltitude() to force the altitude to something
+ * other than the current altitude. LaRCsim doesn't let you do this by just
+ * changing FG_Altitude.
+ *
+ * Revision 1.13 1998/04/25 22:06:28 curt
+ * Edited cvs log messages in source files ... bad bad bad!
+ *
+ * Revision 1.12 1998/04/21 16:59:33 curt
+ * Integrated autopilot.
+ * Prepairing for C++ integration.
+ *
+ * Revision 1.11 1998/04/18 04:14:04 curt
+ * Moved fg_debug.c to it's own library.
+ *
+ * Revision 1.10 1998/02/07 15:29:37 curt
+ * Incorporated HUD changes and struct/typedef changes from Charlie Hotchkiss
+ * <chotchkiss@namg.us.anritsu.com>
+ *
+ * Revision 1.9 1998/01/27 00:47:53 curt
+ * Incorporated Paul Bleisch's <pbleisch@acm.org> new debug message
+ * system and commandline/config file processing code.
+ *
+ * Revision 1.8 1998/01/19 19:27:03 curt
+ * Merged in make system changes from Bob Kuehne <rpk@sgi.com>
+ * This should simplify things tremendously.
+ *
+ * Revision 1.7 1998/01/19 18:40:23 curt
+ * Tons of little changes to clean up the code and to remove fatal errors
+ * when building with the c++ compiler.
+ *
+ * Revision 1.6 1998/01/19 18:35:43 curt
+ * Minor tweaks and fixes for cygwin32.
+ *
+ * Revision 1.5 1997/12/30 20:47:37 curt
+ * Integrated new event manager with subsystem initializations.
+ *
+ * Revision 1.4 1997/12/10 22:37:42 curt
+ * Prepended "fg" on the name of all global structures that didn't have it yet.
+ * i.e. "struct WEATHER {}" became "struct fgWEATHER {}"
+ *
+ * Revision 1.3 1997/08/27 03:30:04 curt
+ * Changed naming scheme of basic shared structures.
+ *
+ * Revision 1.2 1997/05/29 22:39:57 curt
+ * Working on incorporating the LaRCsim flight model.
+ *
* Revision 1.1 1997/05/29 02:35:04 curt
* Initial revision.
