# PortRelay —— 常用命令
#   make test        运行 gofmt 检查、go vet 与全部测试（-race）
#   make server      交叉编译 Linux 服务端到 dist/
#   make agent       编译当前平台的 Agent 到 bin/
#   make app         构建 macOS 应用 PortRelay.app（需要 Xcode 命令行工具）
#   make install-app 构建并替换 /Applications/PortRelay.app（正在运行的会先退出，装好后重新打开）
#   make dmg         打包 macOS 安装镜像 dist/PortRelay-<版本>.dmg（UNIVERSAL=1 构建通用版本）
#   make release     打包服务端（Linux）与命令行 Agent（Linux / Windows）到 dist/
#   make snapshots   离屏渲染 App 界面截图（tools/ui-snapshots/out）
#   make readme-images 重新生成 README 的全部截图和动图到 docs/images（需要 Google Chrome）
