$0: stage MARC file into reservoir.

Use this batch job to load a file of MARC bibliographic
(with optional item information) or authority records into
the Koha reservoir.

After running this program to stage your file, you can use
either the batch job commit_file.pl or the Koha
Tools option "Manage Staged MARC Records" to load the
records into the main Koha database.

Parameters:
    --file <file_name>      name of input MARC bib file
    --authorities           stage authority records instead of bibs
    --encoding <encoding>   encoding of MARC records, default is UTF-8.
                            Other possible options are: MARC-8,
                            ISO_5426, ISO_6937, ISO_8859-1, EUC-KR
    --format                The MARC transport format to use?
                            Defaults to ISO2709.
                            Available values, MARCXML, ISO2709.
    --match <match_id>      use this option to match records
                            in the file with records already in
                            the database for future overlay.
                            If <match_id> isn't defined, a default
                            MARC21 ISBN & title match rule will be applied
                            for bib imports.
    --add-items             use this option to specify that
                            item data is embedded in the MARC
                            bibs and should be parsed.
    --item-action           action to take if --add-items is specifed;
                            choices are 'always_add',
                            'add_only_for_matches', 'add_only_for_new',
                            'ignore', or 'replace'
    --no-replace            overlay action for record: default is to
                            replace extant with the imported record.
    --no-create             nomatch action for record: default is to
                            create new record with imported record.
    --comment <comment>     optional comment to describe
                            the record batch; if the comment
                            has spaces in it, surround the
                            comment with quotation marks.
    --help or -h            show this message.
