NAME
    MARC::Parser::RAW - Parser for ISO 2709 encoded MARC records

SYNOPSIS
        use MARC::Parser::RAW;

        my $parser = MARC::Parser::RAW->new( $file );

        while ( my $record = $parser->next() ) {
            # do something        
        }

DESCRIPTION
    MARC::Parser::RAW is a lightweight, fault tolerant parser for ISO 2709
    encoded MARC records. Tags, indicators and subfield codes are not
    validated against the MARC standard. Record length from leader and field
    lengths from the directory are ignored. Records with a faulty structure
    will be skipped with a warning. The resulting data structure is
    optimized for usage with the Catmandu data tool kit.

    MARC::Parser::RAW expects UTF-8 encoded files as input. Otherwise
    provide a filehande with a specified I/O layer or specify encoding.

MARC
    The MARC record is parsed into an ARRAY of ARRAYs:

        $record = [
                [ 'LDR', undef, undef, '_', '00661nam  22002538a 4500' ],
                [ '001', undef, undef, '_', 'fol05865967 ' ],
                ...
                [   '245', '1', '0', 'a', 'Programming Perl /',
                    'c', 'Larry Wall, Tom Christiansen & Jon Orwant.'
                ],
                ...
            ];
