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