-  # A stackable dynamic tree based Rack router.
-  #
-  # Rack::Mount supports Rack's Cascade style of trying several routes until
-  # it finds one that is not a 404. This allows multiple routes to be nested
-  # or stacked on top of each other. Since the application endpoint can
-  # trigger the router to continue matching, middleware can be used to add
-  # arbitrary conditions to any route. This allows you to route based on
-  # other request attributes, session information, or even data dynamically
-  # pulled from a database.
