{ Pass on command-line the URL (usually just a filename; "-" means stdin)
of 3D model file and the name of placeholder detection routine
(like "x3dshape" or "blender").
We will output information about detected placeholders in the file.
For example,
./placeholder_names model.x3d blender
./placeholder_names ../fps_game/data/example_level/example_level.x3d blender
will assume that model.x3d was created using standard Blender X3D exporter,
and will show Blender object names for every shape in the model.
See TGameSceneManager.LoadLevel for a description where we use
placeholders in the engine. }
