+    (description
+     "Virality Engine provides a system and workflow that helps describe the
+elements needed to write 2D or 3D games.  It was designed with several domain
+specific languages that make it easier to describe, manipulate, and use assets
+commonly found in game making.  Such assets include (but are not limited to)
+textures, materials, shader programs, and scene trees of actors that are
+available for instantiation.  Virality Engine also knows how to accept input
+from keyboards and most joysticks and gamepads.
+
+The component system is a hybrid model between an ECS and an object model.  The
+components are defined similar to CLOS defclass, and regular generic methods
+can be used with them.  Components are added to Actors which represent game
+concepts like players, scenery, effects, etc.  We define a component protocol
+invoked by Virality Engine to move your components to the next state and
+render them each frame.")
