+
+Using through extending the class.
+  
+  class Foo
+    extend Forwardable
+
+    def_delegators("@out", "printf", "print")
+    def_delegators(:@in, :gets)
+    def_delegator(:@contents, :[], "content_at")

+
+== Methods
+
+--- Forwardable#def_instance_delegators(accessor, *methods)
+
+      adding the delegations for each method of ((|methods|)) to
+      ((|accessor|)).
+
+--- Forwardable#def_instance_delegator(accessor, method, ali = method)
+      
+      adding the delegation for ((|method|)) to ((|accessor|)). When
+      you give optional argument ((|ali|)), ((|ali|)) is used as the
