type Command interface {
	// Use is the one-line usage message.
	// Recommended syntax is as follow:
	//   [ ] identifies an optional argument. Arguments that are not enclosed in brackets are required.
	//   ... indicates that you can specify multiple values for the previous argument.
	//   |   indicates mutually exclusive information. You can use the argument to the left of the separator or the
	//       argument to the right of the separator. You cannot use both arguments in a single use of the command.
	//   { } delimits a set of mutually exclusive arguments when one of the arguments is required. If the arguments are
	//       optional, they are enclosed in brackets ([ ]).
	// Example: add [-F file | -D dir]... [-f format] profile
	Use() string

	// Short returns string about short description of the command
	// the string is shown in help screen of cobra command
	Short() string

	// Setup is used to setup flags or pre-run steps for the command.
	//
	// For example,
	//  cmd.Flags().IntVarP(&r.num, "num", "n", 5, "description")
	//
	Setup(cmd *cobra.Command)

	// Run runs the command runner
	// run returns command runner which is a function with dependency
	// injected arguments.
	//
	// For example,
	//  Command{
	//   Run: func(l lib.Logger) {
	// 	   l.Info("i am working")
	// 	 },
	//  }
	//
	Run(cmd *cobra.Command) CommandRunner // TODO, RunE instead?
