     ##
     # This file serves mostly as a specification for Storage engines. There is no requirement
-    # that storage engines must be a subclass of this class. However, any storage engine must
-    # conform to the following interface:
+    # that storage engines must be a subclass of this class.
     #
-    # The storage engine must respond to store!, taking an uploader object and a
-    # CarrierWave::SanitizedFile as parameters. This method should do something to store
-    # the given file, and then return an object.
-    #
-    # The storage engine must respond to retrieve!, taking an uploader object and an identifier
-    # as parameters. This method should do retrieve and then return an object.
-    #
-    # The objects returned by store! and retrieve! both *must* respond to +identifier+, taking
-    # no arguments. Identifier is a string that uniquely identifies this file and can be used
-    # to retrieve it later.
