## SYNOPSIS
        use [CPAN::Meta::YAML](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AYAML/markdown);

        # reading a META file

        $yaml_text = do { local $/; <$fh> };
        $yaml = [CPAN::Meta::YAML](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AYAML/markdown)->read_string($yaml_text)
          or die [CPAN::Meta::YAML](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AYAML/markdown)->errstr;

        # finding the metadata
        $meta = $yaml->[0];

        # writing a META file
        $yaml_text = $yaml->write_string
          or die [CPAN::Meta::YAML](https://www.chedong.com/phpMan.php/perldoc/CPAN%3A%3AMeta%3A%3AYAML/markdown)->errstr;

        print $fh $yaml_text;

## DESCRIPTION
    This module implements a subset of the YAML specification for use in reading and writing CPAN
    metadata files like META.yml and MYMETA.yml. It should not be used for any other general YAML
    parsing or generation task.

    NOTE: META.yml (and MYMETA.yml) files should be UTF-8 encoded. Users are responsible for proper
    encoding and decoding. In particular, the "read" and "write" methods do not support UTF-8 and
    should not be used.

## SUPPORT
    This module is currently derived from [YAML::Tiny](https://www.chedong.com/phpMan.php/perldoc/YAML%3A%3ATiny/markdown) by Adam Kennedy. If there are bugs in how it
    parses a particular META.yml file, please file a bug report in the [YAML::Tiny](https://www.chedong.com/phpMan.php/perldoc/YAML%3A%3ATiny/markdown) bugtracker:
