A question about cocos2d-html5 API

who can tell me why there is no cc.Sprite in API ,but there is ccSprite.js in file index?

The cc.Sprite’s API is already in the online document, at http://www.cocos2d-x.org/reference/html5-js/V2.2/index.html

and you can find it in cc.Class/cc.Node/cc.NodeRGBA/cc.Sprite.
