MooseX::MetaDescription allows you to add arbitrary out of band metadata to your Moose classes and attributes. This will allow you to track out of band data along with attributes, which is very useful for say serializing Moose classes in HTML or XML.
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
