+-- This function does three things:
+--
+-- * Creates the route datatype AppRoute. Every valid URL in your
+--   application can be represented as a value of this type.
+-- * Creates the associated type:
+--       type instance Route App = AppRoute
+-- * Creates the value resourcesApp which contains information on the
+--   resources declared below. This is used in Handler.hs by the call to
+--   mkYesodDispatch
+--
+-- What this function does *not* do is create a YesodSite instance for
+-- App. Creating that instance requires all of the handler functions
+-- for our application to be in scope. However, the handler functions
+-- usually require access to the AppRoute datatype. Therefore, we
+-- split these actions into two functions and place them in separate files.
