+	   ATTENTION: USE cc.director INSTEAD OF cc.Director.<br/>
+	   cc.director is a singleton object which manage your game's logic flow.<br/>
+	   Since the cc.director is a singleton, you don't need to call any constructor or create functions,<br/>
+	   the standard way to use it is by calling:<br/>
+	     - cc.director.methodName(); <br/>
+	
+	   It creates and handle the main Window and manages how and when to execute the Scenes.<br/>
+	   <br/>
+	   The cc.director is also responsible for:<br/>
+	     - initializing the OpenGL context<br/>
+	     - setting the OpenGL pixel format (default on is RGB565)<br/>
+	     - setting the OpenGL buffer depth (default on is 0-bit)<br/>
+	     - setting the color for clear screen (default one is BLACK)<br/>
+	     - setting the projection (default one is 3D)<br/>
+	     - setting the orientation (default one is Portrait)<br/>
+	     <br/>
+	   <br/>
+	   The cc.director also sets the default OpenGL context:<br/>
+	     - GL_TEXTURE_2D is enabled<br/>
+	     - GL_VERTEX_ARRAY is enabled<br/>
+	     - GL_COLOR_ARRAY is enabled<br/>
+	     - GL_TEXTURE_COORD_ARRAY is enabled<br/>
+	</p>
+	<p>
+	  cc.director also synchronizes timers with the refresh rate of the display.<br/>
+	  Features and Limitations:<br/>
+	     - Scheduled timers & drawing are synchronizes with the refresh rate of the display<br/>
+	     - Only supports animation intervals of 1/60 1/30 & 1/15<br/>
+	</p>

+	    注意：用 cc.director 代替 cc.Director。<br/>
+	    cc.director 一个管理你的游戏的逻辑流程的单例对象。<br/>
+	    由于 cc.director 是一个单例，你不需要调用任何构造函数或创建函数，<br/>
+	    使用它的标准方法是通过调用：<br/>
+	      - cc.director.methodName();
+	    <br/>
+	    它创建和处理主窗口并且管理什么时候执行场景。<br/>
+	    <br/>
+	    cc.director 还负责：<br/>
+	     - 初始化 OpenGL 环境。<br/>
+	     - 设置OpenGL像素格式。(默认是 RGB565)<br/>
+	     - 设置OpenGL缓冲区深度 (默认是 0-bit)<br/>
+	     - 设置空白场景的颜色 (默认是 黑色)<br/>
+	     - 设置投影 (默认是 3D)<br/>
+	     - 设置方向 (默认是 Portrait)<br/>
+	   <br/>
+	   cc.director 设置了 OpenGL 默认环境 <br/>
+	     - GL_TEXTURE_2D   启用。<br/>
+	     - GL_VERTEX_ARRAY 启用。<br/>
+	     - GL_COLOR_ARRAY  启用。<br/>
+	     - GL_TEXTURE_COORD_ARRAY 启用。<br/>
+	</p>
+	<p>
+	  cc.director 也同步定时器与显示器的刷新速率。
+	  <br/>
+	  特点和局限性: <br/>
+	     - 将计时器 & 渲染与显示器的刷新频率同步。<br/>

-	   ATTENTION: USE cc.director INSTEAD OF cc.Director.<br/>
-	   cc.director is a singleton object which manage your game's logic flow.<br/>
-	   Since the cc.director is a singleton, you don't need to call any constructor or create functions,<br/>
-	   the standard way to use it is by calling:<br/>
-	     - cc.director.methodName(); <br/>
-	
-	   It creates and handle the main Window and manages how and when to execute the Scenes.<br/>
-	   <br/>
-	   The cc.director is also responsible for:<br/>
-	     - initializing the OpenGL context<br/>
-	     - setting the OpenGL pixel format (default on is RGB565)<br/>
-	     - setting the OpenGL buffer depth (default on is 0-bit)<br/>
-	     - setting the color for clear screen (default one is BLACK)<br/>
-	     - setting the projection (default one is 3D)<br/>
-	     - setting the orientation (default one is Portrait)<br/>
-	     <br/>
-	   <br/>
-	   The cc.director also sets the default OpenGL context:<br/>
-	     - GL_TEXTURE_2D is enabled<br/>
-	     - GL_VERTEX_ARRAY is enabled<br/>
-	     - GL_COLOR_ARRAY is enabled<br/>
-	     - GL_TEXTURE_COORD_ARRAY is enabled<br/>
-	</p>
-	<p>
-	  cc.director also synchronizes timers with the refresh rate of the display.<br/>
-	  Features and Limitations:<br/>
-	     - Scheduled timers & drawing are synchronizes with the refresh rate of the display<br/>
-	     - Only supports animation intervals of 1/60 1/30 & 1/15<br/>
-	</p>
-	
-	!#zh
-	<p>
-	    注意：用 cc.director 代替 cc.Director。<br/>
-	    cc.director 一个管理你的游戏的逻辑流程的单例对象。<br/>
-	    由于 cc.director 是一个单例，你不需要调用任何构造函数或创建函数，<br/>
-	    使用它的标准方法是通过调用：<br/>
-	      - cc.director.methodName();
-	    <br/>
-	    它创建和处理主窗口并且管理什么时候执行场景。<br/>
-	    <br/>
-	    cc.director 还负责：<br/>
-	     - 初始化 OpenGL 环境。<br/>
-	     - 设置OpenGL像素格式。(默认是 RGB565)<br/>
-	     - 设置OpenGL缓冲区深度 (默认是 0-bit)<br/>
-	     - 设置空白场景的颜色 (默认是 黑色)<br/>
-	     - 设置投影 (默认是 3D)<br/>
-	     - 设置方向 (默认是 Portrait)<br/>
-	   <br/>
-	   cc.director 设置了 OpenGL 默认环境 <br/>
-	     - GL_TEXTURE_2D   启用。<br/>
-	     - GL_VERTEX_ARRAY 启用。<br/>
-	     - GL_COLOR_ARRAY  启用。<br/>
-	     - GL_TEXTURE_COORD_ARRAY 启用。<br/>
-	</p>
-	<p>
-	  cc.director 也同步定时器与显示器的刷新速率。
-	  <br/>
-	  特点和局限性: <br/>
-	     - 将计时器 & 渲染与显示器的刷新频率同步。<br/>
-	     - 只支持动画的间隔 1/60 1/30 & 1/15。<br/>

+	EventTarget is an object to which an event is dispatched when something has occurred.
+	Entity are the most common event targets, but other objects can be event targets too.
+	
+	Event targets are an important part of the Fireball event model.
+	The event target serves as the focal point for how events flow through the scene graph.
+	When an event such as a mouse click or a keypress occurs, Fireball dispatches an event object
+	into the event flow from the root of the hierarchy. The event object then makes its way through
+	the scene graph until it reaches the event target, at which point it begins its return trip through
+	the scene graph. This round-trip journey to the event target is conceptually divided into three phases:
+	- The capture phase comprises the journey from the root to the last node before the event target's node
+	- The target phase comprises only the event target node
+	- The bubbling phase comprises any subsequent nodes encountered on the return trip to the root of the tree
+	See also: http://www.w3.org/TR/DOM-Level-3-Events/#event-flow

+	 - _getCapturingTargets
+	 - _getBubblingTargets

-	EventTarget is an object to which an event is dispatched when something has occurred.
-	Entity are the most common event targets, but other objects can be event targets too.
-	
-	Event targets are an important part of the Fireball event model.
-	The event target serves as the focal point for how events flow through the scene graph.
-	When an event such as a mouse click or a keypress occurs, Fireball dispatches an event object
-	into the event flow from the root of the hierarchy. The event object then makes its way through
-	the scene graph until it reaches the event target, at which point it begins its return trip through
-	the scene graph. This round-trip journey to the event target is conceptually divided into three phases:
-	- The capture phase comprises the journey from the root to the last node before the event target's node
-	- The target phase comprises only the event target node
-	- The bubbling phase comprises any subsequent nodes encountered on the return trip to the root of the tree
-	See also: http://www.w3.org/TR/DOM-Level-3-Events/#event-flow

-	 - _getCapturingTargets
-	 - _getBubblingTargets
