=head1 DESCRIPTION
-B<The whole concept behind this module is still considered
-experimental, and it could go away in the future!>
-
This utility module is designed to help authors of Moose extensions
write extensions that are able to cooperate with other Moose
extensions. To do this, you must write your extensions as roles, which
-can then be dynamically applyied to the caller's metaclasses.
+can then be dynamically applied to the caller's metaclasses.
This module makes sure to preserve any existing superclasses and roles
already set for the meta objects, which means that any number of
attributes defined yet.
The easiest way to ensure that this happens is to use
-L<Moose::Exporter> and provide an C<init_meta> method that will be
-called when imported.
+L<Moose::Exporter>, which can generate the appropriate C<init_meta>
+method for you, and make sure it is called when imported.
