=head1 NAME
bulkmarcimport.pl - Import bibliographic/authority records into Koha
=head1 USAGE
$ export KOHA_CONF=/etc/koha.conf
$ perl misc/migration_tools/bulkmarcimport.pl -d -commit 1000 \\
-file /home/jmf/koha.mrc -n 3000
=head1 WARNING
Don't use this script before you've entered and checked your MARC parameters
tables twice (or more!). Otherwise, the import won't work correctly and you
will get invalid data.
=head1 DESCRIPTION
=over
=item B<-h>
This version/help screen
=item B<-b, -biblios>
Type of import: bibliographic records
=item B<-a, -authorities>
Type of import: authority records
=item B<-file>=I<FILE>
The I<FILE> to import
=item B<-v>
Verbose mode. 1 means "some infos", 2 means "MARC dumping"
=item B<-fk>
Turn off foreign key checks during import.
=item B<-n>=I<NUMBER>
The I<NUMBER> of records to import. If missing, all the file is imported
=item B<-o, -offset>=I<NUMBER>
File offset before importing, ie I<NUMBER> of records to skip.
=item B<-commit>=I<NUMBER>
The I<NUMBER> of records to wait before performing a 'commit' operation
=item B<-l>
File logs actions done for each record and their status into file
=item B<-append>
If specified, data will be appended to the logfile. If not, the logfile will be erased for each execution.
=item B<-t, -test>
Test mode: parses the file, saying what he would do, but doing nothing.
=item B<-s>
Skip automatic conversion of MARC-8 to UTF-8. This option is provided for
debugging.
=item B<-c>=I<CHARACTERISTIC>
The I<CHARACTERISTIC> MARC flavour. At the moment, only I<MARC21> and
I<UNIMARC> are supported. MARC21 by default.
=item B<-d>
Delete EVERYTHING related to biblio in koha-DB before import. Tables: biblio,
biblioitems, items
=item B<-m>=I<FORMAT>
Input file I<FORMAT>: I<MARCXML> or I<ISO2709> (defaults to ISO2709)
=item B<-authtypes>
file yamlfile with authoritiesTypes and distinguishable record field in order
to store the correct authtype
=item B<-yaml>
yaml file format a yaml file with ids
=item B<-filter>
list of fields that will not be imported. Can be any from 000 to 999 or field,
subfield and subfield's matching value such as 200avalue
=item B<-insert>
if set, only insert when possible
=item B<-update>
if set, only updates (any biblio should have a matching record)
=item B<-all>
if set, do whatever is required
=item B<-k, -keepids>=<FIELD>
Field store ids in I<FIELD> (useful for authorities, where 001 contains the
authid for Koha, that can contain a very valuable info for authorities coming
from LOC or BNF. useless for biblios probably)
=item B<-match>=<FIELD>
I<FIELD> matchindex,fieldtomatch matchpoint to use to deduplicate fieldtomatch
can be either 001 to 999 or field and list of subfields as such 100abcde
=item B<-i,-isbn>

is useful when something has set barcodes to be a biblio ID, or similar
(usually other software.)
