After a certain period of time, the archived results that are
      being maintained are no longer needed. A delete_archive option has been
      provided that will remove the archived test logs (tar.gz). The
      associated report web pages will be maintained. In order to remove the
      reports from the web pages use the delete_reports option in conjunction
      with the -delete_archives option. Just like in the
      archive option this command takes as an argument the number of weeks to
      keep.
>> rrt -delete_archives 4 >> rrt -da 12
In the first example any archived folder (tar.gz) older than 4 weeks will be deleted. In the second, anything older than 12 weeks will be deleted.
