           # From Perl
           use Catmandu;

           my $importer = Catmandu->importer('MARC', file => "/foo/bar.xml" , type => 'XML');
           my $exporter = Catmandu->exporter('MARC', file => "bar.json", type => 'MiJ' );

           $exporter->add($importer);
           $exporter->commit;

CONFIGURATION

       file
           Write output to a local file given by its path or file handle.  Alternatively a scalar
           reference can be passed to write to a string and a code reference can be used to write
           to a callback function.

       fh  Write the output to an IO::Handle. If not specified, Catmandu::Util::io is used to
           create the output handle from the "file" argument or by using STDOUT.

       fix An ARRAY of one or more fixes or file scripts to be applied to exported items.

       encoding
           Binmode of the output stream "fh". Set to "":utf8"" by default.

METHODS

       See Catmandu::Exporter, Catmandu::Addable, Catmandu::Fixable, Catmandu::Counter, and
       Catmandu::Logger for a full list of methods.

FORMAT

       The MARC-in-JSON record format contains two fields:

          * 'leader' - the MARC leader
          * 'fields' - an array of MARC fields

       Each item in the MARC fields array contains the MARC tag and as value a hash containing
       three fields:

          * 'subfields' - an array of MARC subfields
          * 'ind1' - the first indicator of the MARC tag
          * 'ind2' - the second indicator of the MARC tag

       Each subfield item is an hash containing the MARC subfield tag and its value.

       An example of one MARC record in the MiJ serialization format is given below:

           {
             "leader": "0000cam  2200000   4500",
             "fields": [
               {
                 "100": {
                   "subfields": [
                     {
                       "a": "Huberman, Leo,"
                     },
                     {
                       "d": "1903-1968."
                     }
                   ],
                   "ind1": "1",
                   "ind2": " "
                 }
               },
               {
                 "700": {
                   "subfields": [
                     {
                       "a": "Sweezy, Paul M."
                     },
                     {
                       "q": "(Paul Marlor),"
                     },
                     {
                       "d": "1910-2004."
                     }
                   ],
                   "ind1": "1",
                   "ind2": " "
                 }
               },
               ...
           }
