【使用说明】：
1、使用前提条件：
安装了Flash CS3软件；
安装了 Adobe Extension Manager 1.8扩展管理器，如果没有请先到这里下载： http://www.adobe.com/cn/exchange/em_download/；
下载了LRCParser组件安装包文件： LRCParser.mxp
2、打开LRCParser组件安装包，将LRCParser组件安装到Flash CS3里；
3、将LRCParser组件拖到正在打开的fla文件的场景或库里，然后在调用代码（或类）的上面加上“import com.klstudio.media.LRCParser;”一行代码就可以了，接下来就"按照上面的接口和参考下面的调用实现"来调用这个解析器了。
