-- | A game requires the engine provided by the library, perhaps customized,
-- and game content, defined completely afresh for the particular game.
-- The general type of the content is @CDefs@ and it has instances
-- for all content kinds, such as items kinds
-- (@Game.LambdaHack.Content.ItemKind@).
-- The possible kinds are fixed in the library and all defined in the same
-- directory. On the other hand, game content, that is all elements
-- of @CDefs@ instances, are defined in a directory
-- of the game code proper, with names corresponding to their kinds.
