var RootCmd = &cobra.Command{
	Use:   "hostbridge",
	Short: "Lend a browser visor this host's sockets",
	Long: `Lend a browser visor this host's sockets.

A visor running in a browser tab cannot listen on a port or open a raw
socket. The bridge does that for it. The tab connects to the bridge over a
WebSocket on loopback, then asks it to dial, listen on TCP or bind UDP.

Only pages in --origin may connect, and only with the token in the printed
URL. The token is kept in --token-file, so the URL stays the same when the
bridge restarts. The first visor to connect pairs with the bridge, which
then serves only that visor until it is run with --unpair. The bridge
holds no keys of its own.`,
