+= Forwardable
+
+A Module to define delegations for selected methods to a class.
+
+== Usage
+
+Using through extending the class.
+  
+  class Foo
+    extend Forwardable
+
+    def_delegators("@out", "printf", "print")
+    def_delegators(:@in, :gets)
+    def_delegator(:@contents, :[], "content_at")
+  end
+  f = Foo.new
+  f.printf ...
+  f.gets
+  f.content_at(1)
+
+== 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
+      name of the delegation method, instead of ((|method|)).

+
+= SingleForwardable
+
+a Module to define delegations for selected methods to an object.
+
+== Usage
+

+== Methods

+--- SingleForwardable#def_singleton_delegators(accessor, *methods)
+
+      adding the delegations for each method of ((|methods|)) to

+クラスに対しメソッドの委譲機能を定義します.
+
+== 使い方
+
+クラスに対してextendして使います. 
+  
+  class Foo
+    extend Forwardable
+
+    def_delegators("@out", "printf", "print")
+    def_delegators(:@in, :gets)
+    def_delegator(:@contents, :[], "content_at")
+  end
+  f = Foo.new
+  f.printf ...
+  f.gets
+  f.content_at(1)
+
+== メソッド
+
+--- Forwardable#def_instance_delegators(accessor, *methods)
+
+      ((|methods|))で渡されたメソッドのリストを((|accessorに|))委譲する
+      ようにします.
+
+--- Forwardable#def_instance_delegator(accessor, method, ali = method)
+
+      ((||method|))で渡されたメソッドを((|accessor|))に委譲するようにし
+      ます. ((|ali|))が引数として渡されたときは, メソッド((|ali|))が呼ば
+      れたときには, ((|accessor|))に対し((|method|))を呼び出します.
+
+--- Forwardable#def_delegators(accessor, *methods)
+
+      ((|Forwardable#def_instance_delegators|))の別名です.
+
+--- Forwardable#def_delegator(accessor, method, ali = method)
+
+      ((|Forwardable#def_instance_delegator|))の別名です.
