+Evan 增强版特性
+------
+* 所有TLS相关协议支持自定义SNI伪装(sni参数)
+  - 例子: gost -L http://:8888 -F wss://home.evan.run:443?sni=www.baidu.com
+  - 在SNI伪装的基础上再伪装Host: 
+    - gost -L http://:8888 -F wss://home.evan.run:443?sni=www.baidu.com&host=www.qq.com
+* 请求头深度自定义(header参数)
+  - 例子: gost -L http://:8888 -F wss://home.evan.run:443?header=header.txt
+  - header.txt内容同HTTP协议的Header格式,即HeaerName: Value,若需要去除对应Header,则在HeaderName前加--,如--User-Agent
+* HTTP CONNECT方法支持自定义Host(常用于免流混淆)
+  - 例子: gost -L http://:8888 -F http://evan.run:80?host=cdn.dingding.com -F socks5://127.0.0.1:1080
+* 修改默认User Agent为Google默认浏览器的UA,修改代理默认UA为nginx
+
+初步防检测防杀毒处理脚本
+------
+编译后的文件使用strong_mod.sh脚本处理可初步解决杀毒软件报毒
