//VideoIM文档生成日期：2005.10.12
//
//(1)概述：
//类名称：CommandResources
//类说明：
//	提供本应用所需要的各种资源的Mapper的功能，仿照BlueGammon程序的做法。
* 
//所在子系统：VideoIM
//
//系统总描述:
	    我们提供的VideoIM手机自动拍照上传器J2ME版本[开源]是
	    一个可以下载到手机(例如Nokia7610已经确实可以下载安装并正常运行)的应用程序，
	    用来自动驱动手机摄像头定时拍摄,并后台将JPEG图像(很小，大约几KB)上传到服务器上，
	    这样就可以帮助其他系统工作，比如PC机上的MSN Messenger可以和你的移动MSN Messenger
	    通过这种方式视频聊天，对方可以每隔十几秒钟看到你的手机所看到的画面了。

	 子系统描述：
		VideoIM的功能列表：
			1:我要MobileWebCam
				启动MobileWebCam
				停止MobileWebCam
			2:MobileWebCam设置
			3:关于我
			4:退出
