761 if set, do whatever is required
763 =item B<-k, -keepids>=<FIELD>
765 Field store ids in I<FIELD> (useful for authorities, where 001 contains the
766 authid for Koha, that can contain a very valuable info for authorities coming
767 from LOC or BNF. useless for biblios probably)
769 =item B<-match>=<FIELD>
771 I<FIELD> matchindex,fieldtomatch matchpoint to use to deduplicate fieldtomatch
772 can be either 001 to 999 or field and list of subfields as such 100abcde
776 If set, a search will be done on isbn, and, if the same isbn is found, the
777 biblio is not added. It's another method to deduplicate. B<-match> & B<-isbn>
782 Clean ISBN fields from entering biblio records, ie removes hyphens. By default,
783 ISBN are cleaned. --nocleanisbn will keep ISBN unchanged.
787 Source bib I<TAG> for reporting the source bib number
789 =item B<-y>=I<SUBFIELD>
791 Source I<SUBFIELD> for reporting the source bib number
793 =item B<-idmap>=I<FILE>
795 I<FILE> for the koha bib and source id
799 Store ids in 009 (useful for authorities, where 001 contains the authid for
800 Koha, that can contain a very valuable info for authorities coming from LOC or
801 BNF. useless for biblios probably)
803 =item B<-dedupbarcode>
805 If set, whenever a duplicate barcode is detected, it is removed and the attempt
806 to add the record is retried, thereby giving the record a blank barcode. This
807 is useful when something has set barcodes to be a biblio ID, or similar
808 (usually other software.)
812 This is the code for the framework that the requested records will have attached
813 to them when they are created. If not specified, then the default framework
816 =item B<-custom>=I<MODULE>
818 This parameter allows you to use a local module with a customize subroutine
819 that is called for each MARC record.
820 If no filename is passed, LocalChanges.pm is assumed to be in the
821 migration_tools subdirectory. You may pass an absolute file name or a file name
822 from the migration_tools directory.
824 =item B<-marcmodtemplate>=I<TEMPLATE>
826 This parameter allows you to specify the name of an existing MARC
827 modification template to apply as the MARC records are imported (these
828 templates are created in the "MARC modification templates" tool in Koha).
829 If not specified, no MARC modification templates are used (default).
