=head1 NAME

Test::CPAN::Meta::YAML - Validate a F file within a CPAN distribution.

=head1 SYNOPSIS

There are two forms this module can be used.

The first is a standalone test of your distribution's F file:

  use Test::More;
  eval "use Test::CPAN::Meta::YAML";
  plan skip_all => "Test::CPAN::Meta::YAML required for testing META.yml" if $@;
  meta_yaml_ok();

Note that you may provide an optional label/comment/message/etc to the
function, or one will be created automatically.

The second form allows you to test other F files, or specify a specific
version you wish to test against:

  use Test::More tests => 6;
  use Test::CPAN::Meta::YAML;

  # specify a file and specification version
  meta_spec_ok('META.yml','1.3',$msg);

  # specify the specification version to validate the local META.yml
  meta_spec_ok(undef,'1.3',$msg);

  # specify a file, where the specification version is deduced
  # from the file itself
  meta_spec_ok('META.yml',undef,$msg);

Note that this form requires you to specify the number of tests you will be
running in your test script. Also note that each C is actually two
tests under the hood.

=head1 DESCRIPTION

This module was written to ensure that a F file, provided with a
standard distribution uploaded to CPAN, meets the specifications that slowly
being introduced to module uploads, via the use of L,
L and L.

See L for further details of the CPAN Meta Specification.

=head1 FUNCTIONS

=over

=item * meta_yaml_ok([$msg])

Basic F wrapper around C.

=cut

sub meta_yaml_ok {
    $Test->plan( tests => 2 );
    return meta_spec_ok(undef,undef,@_);
}

=item * meta_spec_ok($file, $version [,$msg])

Validates the named file against the given specification version. Both C<$file>
and C<$version> can be undefined.
