=head1 NAME
Test::YAML::Meta - Validation of the META.yml file in a distribution.
=head1 SYNOPSIS
There are two forms this module can be used.
The first is a standalone test of your distribution's META.yml file:
use Test::More;
eval "use Test::YAML::Meta";
plan skip_all => "Test::YAML::Meta required for testing META.yml" if $@;
meta_yaml_ok();
Note that you may provide an optional label/comment/message/etc to the
function, or one will be created automatically.
The second form allows you to test other META.yml files, or specify a specific
version you wish to test against:
use Test::More test => 6;
use Test::YAML::Meta;
# specify a file and specification version
meta_spec_ok('META.yml','1.3',$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 'meta_spec_ok' is actually 2
tests under the hood.
=head1 DESCRIPTION
This module was written to ensure that a META.yml file, provided with a
standard distribution uploaded to CPAN, meets the specifications that slowly
being introduced to module uploads, via the use of L<ExtUtils::MakeMaker>,
L<Module::Build> and L<Module::Install>.

=over
=item * meta_yaml_ok([$msg])
Basic META.yml wrapper around meta_spec_ok.

sub meta_yaml_ok {

}
=item * meta_spec_ok($file, $version [,$msg])
Validates the named file against the given specification version. Both $file
and $version can be undefined.

=head1 TESTING META FILES
There are currently 3 distributions to test META files:
Test-CPAN-Meta
Test-JSON-Meta
Test-YAML-Meta
All three have slightly different requirements and are intended to be used in
slightly different environments.
Test-YAML-Meta requires a YAML parser, and currently looks for the YAML or
YAML::Syck modules. This is the original variant of the 3 and was intended to
provide a more complete YAML validation of a META.yml.
Test-CPAN-Meta requires the Parse::CPAN::Meta module, which is now part of Perl
Core as of perl-5.10.1. This version is intended to be used by those only
wishing to rely on core modules to test their META.yml files.
Test-JSON-Meta is the most recent addition to the family, and is specifically
aimed at those distributions that use a META.json Meta file. The distribution
requires the JSON module to parse the Meta file.
