Debugging Options:
   --enable-fpe                 Abort on encountering a floating point
                                exception;
   --fgviewer                   Use a model viewer rather than load the entire
                                simulator;

   --log-level={bulk,debug,info,warn,alert}
                                Specify which logging level to use

   --log-class=[ai,environment,flight,general,io,network,sound,terrain,...]
                                Specify which logging class(es) to use
   --log-dir=DIR                Log to directory DIR. The special value
                                'desktop' causes logging to the desktop
                                (OS-dependent location). This option may be
                                given several times, using a different value
                                each time. Inside the specified directory, the
                                written log file is named
                                FlightGear_YYYY-MM-DD_<num>.log, where <num>
                                takes the values 0, 1, 2, etc.
   --trace-read=property        Trace the reads for a property;
   --trace-write=property       Trace the writes for a property;
