fgviewer - An alternative FlightGear viewer application

fgviewer is a viewer application that allows you  to  examine  FlightGear  scenery  and  objects  without
       starting fgfs(1).

FG_ROOT
           If FG_ROOT is set and --fg-root is not set, it specifies the root data directory to use.

       FG_SCENERY
           If FG_SCENERY is set and --fg-scenery is not set, it specifies the scenery directory to use.

fgviewer  exits  with  EXIT_SUCCESS  on  success,  with  EXIT_FAILURE  if  the syntax of the command-line
       arguments is wrong or an error occurs.

$FG_ROOT/defaults.xml
           Default preferences file loaded on startup.

--fg-rootrootdir
              Set  the FlightGear data root directory ($FG_ROOT) to rootdir. If this option is not set, fgviewer
              uses the path specified in the FG_ROOT environment variable or, absent that, the  FlightGear  data
              directory chosen at the time the program was compiled.

       --fg-sceneryscenerydir
              Set  the  FlightGear  scenery  directory  ($FG_SCENERY) to scenerydir.  If this option is not set,
              fgviewer uses the path specified in the FG_SCENERY  environment  variable  or,  absent  that,  the
              Scenery subdirectory inside $FG_ROOT.

       --configconfigfile
              Read configuration directives from configfile.

       --proppropertyvalue
              Set the property named property to value.

       --rendererrend
              Use the renderer named rend to render the scenery. This option is currently not supported.

       --hla  Enable HLA federation.

       --federationfed
              Enable a custom federation named fed.
