SYNOPSIS

       fgviewer  [--fg-root  rootdir]  [--fg-scenery  scenerydir]  [--config  configfile] [--prop
       property value] [--renderer rend] [--hla] [--federation fed]

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.

FILES

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