This functionality is provided as a preview
				  of intended future API capabilities. You are encouraged to use it and report any problems or suggestions using the
				  Fusion API and Scripts forum.
				  Because this is a preview of future functionality, there is the possibility that it will change, which will possibly
				  break any existing programs that use this functionality. Because of that, you should never deliver any programs that use
				  any preview capabilities. For a distributed program, you should wait until it has moved from preview to released state.
