    // Cobra supports Persistent Flags which will work for this command
    // and all subcommands, e.g.:
    // deleteCmd.PersistentFlags().String("foo", "", "A help for foo")

    // Cobra supports local flags which will only run when this command
    // is called directly, e.g.:
    // deleteCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
