-基于 https://github.com/zhanghanyun/backtrace 的重构和优化版本，支持多系统多架构，记录多个线路
+三网回程路由测试
+
+基于 https://github.com/zhanghanyun/backtrace 的重构和优化，与原版存在很大不同
+
+## 功能
+
+- [x] 检测回程显示IPV4地址时的线路，不显示IP地址时显示ASN检测不到，原版[backtrace](https://github.com/zhanghanyun/backtrace)也支持
+- [x] 支持对```4837```、```9929```和```163```线路的判断，原版[backtrace](https://github.com/zhanghanyun/backtrace)也支持
+- [x] 支持对```CN2GT```和```CN2GIA```线路的判断，原版[backtrace](https://github.com/zhanghanyun/backtrace)不支持
+- [x] 支持对```CMIN2```和```CMI```线路的判断，原版[backtrace](https://github.com/zhanghanyun/backtrace)不支持
+- [x] 支持对整个回程路由进行线路分析，与原版[backtrace](https://github.com/zhanghanyun/backtrace)仅进行一次判断不同
+- [x] 修复原版[backtrace](https://github.com/zhanghanyun/backtrace)对IPV4地址信息获取时json解析失败依然打印信息的问题
+- [x] 增加对全平台的编译支持，原版[backtrace](https://github.com/zhanghanyun/backtrace)仅支持linux平台的amd64和arm64架构
 
 ## 使用
