=head1 NAME

export records - This script exports record (biblios or authorities)

=head1 SYNOPSIS

export_records.pl [-h|--help] [--format=format] [--date=date] [--record-type=TYPE] [--dont_export_items] [--deleted_barcodes] [--clean] [--id_list_file=PATH] --filename=outputfile

=head1 OPTIONS

=over

=item B<-h|--help>

Print a brief help message.

=item B<--format>

 --format=FORMAT        FORMAT is either 'xml', 'csv' (biblio records only) or 'marc' (default).

=item B<--date>

 --date=DATE            DATE should be entered as the 'dateformat' syspref is
                        set (dd/mm/yyyy for metric, yyyy-mm-dd for iso,
                        mm/dd/yyyy for us) records exported are the ones that
                        have been modified since DATE.

=item B<--record-type>

 --record-type=TYPE     TYPE is 'bibs' or 'auths'.

=item B<--dont_export_items>

 --dont_export_items    If enabled, the item infos won't be exported.

=item B<--csv_profile_id>

 --csv_profile_id=ID    Generate a CSV file with the given CSV profile id (see tools/csv-profiles.pl)
                        Unless provided, the one defined in the system preference 'ExportWithCsvProfile' will be used.
                        This can only be used to export biblio records.

=item B<--deleted_barcodes>

 --deleted_barcodes     If used, a list of barcodes of items deleted since DATE
                        is produced (or from all deleted items if no date is
                        specified). Used only if TYPE is 'bibs'.

=item B<--clean>

 --clean                removes NSE/NSB.

=item B<--id_list_file>

 --id_list_file=PATH    PATH is a path to a file containing a list of
                        IDs (biblionumber or authid) with one ID per line.
                        This list works as a filter; it is compatible with
                        other parameters for selecting records.

=item B<--filename>

 --filename=FILENAME   FILENAME used to export the data.

=item B<--starting_authid>

 --starting_authid=ID  Export authorities with authid >= ID

=item B<--ending_authid>

 --ending_authid=ID    Export authorities with authid <= ID

=item B<--authtype>

 --authtype=AUTHTYPE   Export authorities from the given AUTHTYPE

=item B<--starting_biblionumber>

 --starting_biblionumber=ID  Export biblio with biblionumber >= ID

=item B<--ending_biblionumber>

 --ending_biblionumber=ID    Export biblio with biblionumber <= ID

=item B<--itemtype>

 --itemtype=ITEMTYPE         Export biblio from the given ITEMTYPE

=item B<--starting_callnumber>

 --starting_callnumber=CALLNUMBER Export biblio with callnumber >=CALLNUMBER

=item B<--ending_callnumber>

 --ending_callnumber=CALLNUMBER Export biblio with callnumber <=CALLNUMBER

=item B<--start_accession>

 --starting_accession=DATE      Export biblio with an item accessionned after DATE

=item B<--end_accession>

 --end_accession=DATE           Export biblio with an item accessionned after DATE
