    # From the command line
    catmandu convert YAML to JSON --pretty 1 < input.yml
    # Export in the line-delimited format
    catmandu convert YAML to JSON --line_delimited 1 < input.yml
    # In a Perl script
    use Catmandu;
    my $exporter = Catmandu->exporter('JSON', fix => 'myfix.txt');
    $exporter->add_many($arrayref);
    $exporter->add_many($iterator);
    $exporter->add_many(sub { });
    $exporter->add($hashref);
    printf "exported %d items\n" , $exporter->count;

This Catmandu::Exporter exports items serialized in JSON format. By default each item is printed condensed on one line.

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.
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.
An ARRAY of one or more fixes or file scripts to be applied to exported items.
Binmode of the output stream "fh". Set to "":utf8"" by default.
Pretty-print JSON
JSON serialization options
Structure the data as a JSON array. Default is 1.
Export items as newline delimited JSON. Default is 0. The "array", "pretty", "indent", "space_before" and "space_after" options will be ignored if "line_delimited" is 1.
