+SUMMARY="Provides mro::* interface compatibility for Perls < 5.9.5"
+DESCRIPTION="The \"mro\" namespace provides several utilities for dealing with method resolution \
+order and method caching in general in Perl 5.9.5 and higher.
+This module provides those interfaces for earlier versions of Perl (back to 5.6.0 anyways).
+It is a harmless no-op to use this module on 5.9.5+. That is to say, code which properly uses \
+MRO::Compat will work unmodified on both older Perls and 5.9.5+.
+If you're writing a piece of software that would like to use the parts of 5.9.5+'s mro:: \
+interfaces that are supported here, and you want compatibility with older Perls, this is the \
+module for you."
