/**
 * Surge & Loon 的运行模式，根据当前网络自动切换模式，此脚本思路来自于Quantumult X。
 * @author: Peng-YM

 *************** Surge配置 ***********************
 * 推荐使用模块：
 * https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tools/RunningMode/running-mode.sgmodule
 * 手动配置：
 * [Script]
 * event network-changed script-path=https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tools/RunningMode/running-mode.js
 *
 *************** Loon配置 ***********************
 * 推荐使用插件：
 * https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tools/RunningMode/running-mode.plugin
 * 手动配置：
 * [Script]
 * network-changed script-path=https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tools/RunningMode/running-mode.js
 *
 *************** 脚本配置 ***********************
 * 推荐使用BoxJS配置。
 * BoxJS订阅：https://raw.githubusercontent.com/Peng-YM/QuanX/master/Tasks/box.js.json
 * (不推荐！)手动配置项为config, 请看注释
