* 本 PAC 地址：http://t.xd.cn/ 欢迎内部传播
* 本 PAC 通过 Dropbox 更新。需要编辑权限的，可以告诉你的 Dropbox 帐号，Share 一下就好了
*
* 建议复制一个临时文件来修改，用 jslint 检查语法
* Mac 下安装 jslint
* brew install jslint
* jslint -process index.pac
* 没装 brew 的，先装个：/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)
*
* 某些黑名单域名，用我的DNS服务器的话，就会解析到境内IP，解析到这些IP时，不需要翻墙
* DNS 服务器：180.153.139.245 180.153.139.246 上海电信服务器，网通用户请勿使用，否则境内很多大网站的 CDN 会把你分配到上海电信附近的服务器
*
* BTW，如果需要根据IP来翻墙，可以用 http://t.xd.cn/ip 但是IP列表非常多，客户端解析会很耗CPU
