73 --format=FORMAT FORMAT is either 'xml' or 'marc' (default)
75 --date=DATE DATE should be entered as the 'dateformat' syspref is
76 set (dd/mm/yyyy for metric, yyyy-mm-dd for iso,
77 mm/dd/yyyy for us) records exported are the ones that
78 have been modified since DATE
80 --record-type=TYPE TYPE is 'bibs' or 'auths'
82 --deleted_barcodes If used, a list of barcodes of items deleted since DATE
83 is produced (or from all deleted items if no date is
84 specified). Used only if TYPE is 'bibs'
86 --clean removes NSE/NSB
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.
