+/** @defgroup drawstuff DrawStuff
+
+DrawStuff is a library for rendering simple 3D objects in a virtual 
+environment, for the purposes of demonstrating the features of ODE.
+It is provided for demonstration purposes and is not intended for
+production use.
+
+@section Notes
+
+In the virtual world, the z axis is "up" and z=0 is the floor.
+
+The user is able to click+drag in the main window to move the camera:
+  * left button - pan and tilt.
+  * right button - forward and sideways.
+  * left + right button (or middle button) - sideways and up.
