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

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
