=head1 NAME CPAN::Kwalify - Interface between CPAN.pm and Kwalify.pm =head1 SYNOPSIS use CPAN::Kwalify; validate($schema_name, $data, $file, $doc); =head1 DESCRIPTION =over =item _validate($schema_name, $data, $file, $doc) $schema_name is the name of a supported schema. Currently only C<distroprefs> is supported. $data is the data to be validated. $file is the absolute path to the file the data are coming from. $doc is the index of the document within $doc that is to be validated. The last two arguments are only there for better error reporting. Relies on being called from within CPAN.pm. Dies if something fails. Does not return anything useful. =item yaml($schema_name) Returns the YAML text of that schema. Dies if something fails. =back =head1 AUTHOR Andreas Koenig C<< <andk@cpan.org> >> =head1 LICENSE This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
