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

           # reading a META file

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:
