+=head1 DESCRIPTION
-=head1 TESTS
+This module provides some useful test functions for Moose based classes. It
+is an experimental first release, so comments and suggestions are very welcome.

-=item does_ok
+=item B<meta_ok ($class_or_object)>
+
+Tests if a class or object has a metaclass.
+
+=item B<does_ok ($class_or_object, $role, ?$message)>
+
+Tests if a class or object does a certain role, similar to what C<isa_ok>
+does for the C<isa> method.

-Tests if a class does a certain role, similar to what isa_ok does for
-isa.
+Tests if a class or object has a certain attribute, similar to what C<can_ok>
+does for the methods.
