cmd/netwatch-server/main.go parsed the command line, ran the check-cidr and prepare-data-dir subcommands and built the fx application itself; the Go style guide puts all of that in internal/ or pkg/. The new package internal/cli does it, with the same arguments, messages and exit codes. main() is now os.Exit(cli.Main(Appname, Version, os.Args[1:], cli.RunServer)): Main takes the function that runs the server, so its tests call it with one that fails them. Appname and Version stay in main, where the build sets Version. Each subcommand writes its error to a writer it is given, and prepare-data-dir also takes the volume and the user's name, so its own tests give it a temporary directory and the user they run as.
