-    This UML Class Diagram introduces the
-    GameWorlds and GameModes concepts that
-    are introduced in 1.0.
-
-    This diagram is not meant to be updated
-    alongside modifications that could be done
-    to GameWorlds and GameModes: it is meant
-    to serve as a template, and hopefully to keep
-    track of what we had in mind when we started
-    to work on this API.
