//go:generate go run ../../tools/winres -program tun
// Command firefox-vpn-tun is the TUN service of the desktop TUN mode: it
// holds the TUN adapter, its routes, and the DNS filters with the system's
// rights, for the core, which stays an ordinary program (internal/tunservice,
// protocol internal/tunapi). The app carries it beside the core and
// installs it once: on Windows as a service in Program Files, on Linux as
// a systemd service in /opt, on macOS as a launchd daemon in
// /Library/Application Support.
//
// firefox-vpn-tun install install or update the service for this user (asks for administrator rights)
// firefox-vpn-tun uninstall remove the service (no prompt while it runs)
// firefox-vpn-tun update make the running service this signed executable
// firefox-vpn-tun -version print the version
//
// On macOS, install and uninstall take -prompt, the reason the
// administrator prompt shows (the app passes it in the user's language).
//
// Exit status: 0 done, 1 failed (the reason on the standard error), 2 bad
// arguments, 3 the administrator permission was not given.
