  44                       other options
  45    --sessions         purge the sessions table.  If you use this while users
  46                       are logged into Koha, they will have to reconnect.
  47    --sessdays DAYS    purge only sessions older than DAYS days (use together with sessions parameter).
  48    -v --verbose       will cause the script to give you a bit more information
  49                       about the run.
  50    --zebraqueue DAYS  purge completed entries from the zebraqueue from
  51                       more than DAYS days ago.
  52    -m --mail          purge the mail queue.
