fgelev is written purely to support the scenery generation process for the svn
scenery. This is just the tool that Mathias wrote to replace some really old tool
where the source vanished and that is used by the scenery generation process
for the svn scenery to place the objects. The tool itself is only written to
support some database scripting together with awk and sed to give the right
SELECT BLA FROM BLUBBER statements. So currently the output/usage of fgelev is
not really thought for everybody use. It's just in the git so that the
sourcecode cannot vanish anymore.[1]
