          // Message from an error.

  }

  fmt.Println(result)
}

func exitErrorf(msg string, args ...interface{}) {
  fmt.Fprintf(os.Stderr, msg+"\n", args...)
  os.Exit(1)
}

The following command can be used to execute the aforementioned code, presuming the code file is called s3_list_object_versions.go:

go run s3_list_object_versions.go BUCKET_NAME
