+
+	Option:			-?
+					-h
+	
+	Description:	Prints a message with an overview of the command line 
+					options and how to run Supermodel.
+					
+	----------------
+	
+	Option:			-print-games
+	
+	Description:	Lists all supported ROM sets.  Not all supported ROM sets
+					are playable yet.
+	
+	----------------
+	
+	Option:			-no-threads
+	
+	Description:	Disables multi-threading.  When enabled (the default), the
+					PowerPC, graphics rendering, and user interface are run in
+					one	thread, sound emulation in a second thread, and the 
+					drive board in a third.  It is enabled by default.  On 
+					single-core systems, multi-threading adds overhead and 
+					slows Supermodel down but can make audio sound a bit 
+					smoother.
+	
+	----------------
+	
+	Option:			-ppc-frequency=<f>
+	
+	Description:	Sets the PowerPC frequency in MHz.  The default is 50. 
+					Higher frequencies will allow games to do more processing
+					per	frame, making them run faster in 'virtual' time, but 
+					may	slow down Supermodel on weaker computers.  Supermodel's
+					performance can frequently be improved by lowering the
+					PowerPC frequency (25 MHz works in many games).  In some
+					games, this will cause timing problems.  The optimum value
+					for this setting will vary from game to game and system to
+					system.  Valid values are 1 to 1000.
+	
+	----------------
+	
+	Option:			-fullscreen
+	
+	Description:	Runs in full screen mode.  The default is to run in a
+					window.
+	
+	----------------
+	
+	Option:			-no-throttle
+	
+	Description:	Disables 60 FPS throttling.  The Model 3 runs at a 60 Hz
+					refresh rate, which Supermodel enforces if this option is 
+					omitted.  Unthrottled operation may not work on some 
+					systems because graphics drivers may lock the refresh rate.

+	
+	Description:	Prints OpenGL driver information and quits.
+	
+	----------------
+

+	Description:	Resolution of the display in pixels.  The default is
+					496x384, the Model 3's native resolution.

+	
+	Option:			-show-fps
+	
+	Description:	Shows the frame rate in the window title bar.
+	
+	----------------
+	
+	Option:			-frag-shader=<file>
+					-vert-shader=<file>
+					
+	Description:	Allows external fragment and vertex shaders to be used for

+					GLSL source code.  The file extension is not important.  By
+					default, Supermodel's internal shader programs are used.

+

+					for all other platforms.  Valid input systems are:
+					
+						dinput		DirectInput.
