  79
  80  --record-type=TYPE     TYPE is 'bibs' or 'auths'

  82  --deleted_barcodes     If used, a list of barcodes of items deleted since DATE

  84                         specified). Used only if TYPE is 'bibs'
  85
  86  --clean                removes NSE/NSB
  87
  88  --id_list_file=PATH    PATH is a path to a file containing a list of
  89                         IDs (biblionumber or authid) with one ID per line.
  90                         This list works as a filter; it is compatible with
