    Options:
      --cleanup                   Cleans up the output directory after the build by removing a built OS image. This option may be useful if you transfer the image via scp to another server using the --opt_destination option. After the image was transferred, you may no longer need it in the output directory.
      --opt_destination=          Transfers a built OS image to another sever via scp, for example: root@10.2.3.4:/. To use this option, you must also set up the SSH_KEY environment variable with a private SSH key of the destination server as the variable value.
