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