  * seem to have any corresponding data anymore (for example: the file in Data/Persistent/Resources has been deleted
  * without removing the related PersistentResource object).
  *
  * If the Neos.Media package is active, this command will also detect any assets referring to broken resources
  * and will remove the respective Asset object from the database when the broken resource is removed.
  *
  * This command will ask you interactively what to do before deleting anything.
