Catmandu::Exporter::MARC::ALEPHSEQ - Exporter for MARC records to Ex Libris' Aleph sequential
=head1 SYNOPSIS
# From the command line
$ catmandu convert MARC to MARC --type ALEPHSEQ < /foo/data.mrc
# From Perl
use Catmandu;
my $importer = Catmandu->importer('MARC', file => "/foo/bar.mrc" , type => 'USMARC');
my $exporter = Catmandu->exporter('MARC', file => "marc.txt", type => 'ALEPHSEQ' );
$exporter->add($importer);
$exporter->commit;
=head1 METHODS
=head2 new(file => $file , %opts)
Create a new L<Catmandu::Exporter> to serialize MARC record into Aleph sequential. Provide the path
of a $file to write exported records to. Optionally the following parameters can be
specified:
record : the key containing the marc record (default: 'record')
record_format : optionally set to 'MARC-in-JSON' when the input format is in MARC-in-JSON
skip_empty_subfields : skip fields which don't contain any data (default: false)
=head1 INHERTED METHODS
=head2 count
=head2 add($hashref)
=head2 add_many($array)
=head2 add_many($iterator)
=head2 add_many(sub {})
=head2 ...
All the L<Catmandu::Exporter> methods are inherited.
