DESCRIPTION
    Parse::CPAN::Meta is a parser for META.json and META.yml files, using
    JSON::PP and/or CPAN::Meta::YAML.

    Parse::CPAN::Meta provides three methods: "load_file",
    "load_json_string", and "load_yaml_string". These will read and
    deserialize CPAN metafiles, and are described below in detail.

    Parse::CPAN::Meta provides a legacy API of only two functions, based on
    the YAML functions of the same name. Wherever possible, identical
    calling semantics are used. These may only be used with YAML sources.

    All error reporting is done with exceptions (die'ing).

    Note that META files are expected to be in UTF-8 encoding, only. When
    converted string data, it must first be decoded from UTF-8.

METHODS
  load_file
      my $metadata_structure = Parse::CPAN::Meta-&gt;load_file('META.json');

      my $metadata_structure = Parse::CPAN::Meta-&gt;load_file('META.yml');

    This method will read the named file and deserialize it to a data
    structure, determining whether it should be JSON or YAML based on the
    filename. On Perl 5.8.1 or later, the file will be read using the
    ":utf8" IO layer.

  load_yaml_string
      my $metadata_structure = Parse::CPAN::Meta-&gt;load_yaml_string($yaml_string);

    This method deserializes the given string of YAML and returns the first
    document in it. (CPAN metadata files should always have only one
    document.) If the source was UTF-8 encoded, the string must be decoded
    before calling "load_yaml_string".

  load_json_string
      my $metadata_structure = Parse::CPAN::Meta-&gt;load_json_string($json_string);

    This method deserializes the given string of JSON and the result. If the
    source was UTF-8 encoded, the string must be decoded before calling
    "load_json_string".

  yaml_backend
      my $backend = Parse::CPAN::Meta-&gt;yaml_backend;

    Returns the module name of the YAML serializer. See "ENVIRONMENT" for
    details.

  json_backend
      my $backend = Parse::CPAN::Meta-&gt;json_backend;

    Returns the module name of the JSON serializer. This will either be
    JSON::PP or JSON. Even if "PERL_JSON_BACKEND" is set, this will return
    JSON as further delegation is handled by the JSON module. See
    "ENVIRONMENT" for details.

FUNCTIONS
    For maintenance clarity, no functions are exported. These functions are
    available for backwards compatibility only and are best avoided in favor
    of "load_file".

  Load
      my @yaml = Parse::CPAN::Meta::Load( $string );

    Parses a string containing a valid YAML stream into a list of Perl data
    structures.

  LoadFile
      my @yaml = Parse::CPAN::Meta::LoadFile( 'META.yml' );

    Reads the YAML stream from a file instead of a string.

ENVIRONMENT
  PERL_JSON_BACKEND
    By default, JSON::PP will be used for deserializing JSON data. If the
    "PERL_JSON_BACKEND" environment variable exists, is true and is not
    "JSON::PP", then the JSON module (version 2.5 or greater) will be loaded
    and used to interpret "PERL_JSON_BACKEND". If JSON is not installed or
    is too old, an exception will be thrown.

  PERL_YAML_BACKEND
    By default, CPAN::Meta::YAML will be used for deserializing YAML data.
    If the "PERL_YAML_BACKEND" environment variable is defined, then it is
    interpreted as a module to use for deserialization. The given module
    must be installed, must load correctly and must implement the "Load()"
    function or an exception will be thrown.
