SYNOPSIS

       fgviewer  [--fg-root  rootdir]  [--fg-scenery  scenerydir]  [--config configfile] [--prop property value]

DESCRIPTION

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

OPTIONS

       --fg-root rootdir
              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-scenery scenerydir
              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.

       --config configfile
              Read configuration directives from configfile.

       --prop property value
              Set the property named property to value.

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

       --hla  Enable HLA federation.

       --federation fed
              Enable a custom federation named fed.

EXIT STATUS

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

ENVIRONMENT

       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.
