• clash (link) 可以在linux/windows/Android上使用。它通过定义proxy group and rule来实现基于rule的traffic分发。简单的说，proxy group是proxy的集合，并可以通过type来定义怎么从一组proxy中找到一个proxy用于traffic proxy。rule就是根据ip/url把traffic mapping到不同的proxy group.
• clash configuration file is config.yaml. 各种机场需要提高相应的config.yaml for proxy group and rule.

• 用wget下载bywa机场的订阅链接，得到的是base64 encode的ss serverlist，不是clash config.yaml。可以通过"curl -H “User-Agent: ClashForAndroid/2.0.0” “得到clash config.yaml，详见link。
• 或者使用订阅转换服务，将其它订阅转换为 Clash 订阅。
