stderr 要输出么，这里是直接吞掉，没有暴露给用户？

通过下面的 err 处理可能更清晰一点？

cmd 里面再来一个 cmd，这个包层级可以优化下吗，并且这个 cmd 和 luanch 又是在同一级。如果你考虑 sub command 方式，建议按子命令把层级调整清晰一些。

dev-launcher 本身是一个拥有 main.go 的程序，所以他的包下面有 cmd 文件夹是不是也可以？
'cmd 和 luanch 又是在同一级' 这个问题，那把 luanch 转移到 pkg 里面吗？

将目录 dev-launch.cmd 改为 dev-launch.subcmd
reload 操作还是放在了 reload 子命令，感觉修改为子命令形式后，不适合用 root 做 reload 操作

reload、status、stop 等操作应该是一个级别，一般 root 就是不放东西的
可以参考 bkpaas-cli ：

没跑的话，就不要用 run 这个词，确实容易有误导

看到这里的解析命令，想到考虑后续通过 http 或者 xmlrpc 完成与 supervisor 的通信。这样甚至去除dev-launcher 这个二进制，直接集成到 dev-entrypoint 中
