+=head1 INHERITANCE
+
+B<Class::MOP::Class> is a subclass of L<Class::MOP::Module>
+
=head1 METHODS
=head2 Self Introspection
=item B<initialize ($package_name, %options)>
-This initializes and returns returns a B<Class::MOP::Class> object
-for a given a C<$package_name>.
+This initializes and returns returns a B<Class::MOP::Class> object for
+a given a C<$package_name>. If a metaclass already exists for the
+package, it simply returns it instead of creating a new one.
=item B<construct_class_instance (%options)>
C<bless>-ing into your package of choice. It works in conjunction
with the Attribute protocol to collect all applicable attributes.
-This will construct and instance using a HASH ref as storage
+This will construct an instance using a HASH ref as storage
(currently only HASH references are supported). This will collect all
the applicable attributes and layout out the fields in the HASH ref,
it will then initialize them using either use the corresponding key
=item B<get_method_map>
-Returns a HASH ref of name to CODE reference mapping for this class.
+Returns a HASH ref of name to L<Class::MOP::Method> instance mapping
+for this class.
=item B<method_metaclass>
=item B<find_method_by_name ($method_name)>
-This will return a CODE reference of the specified C<$method_name>,
-or return undef if that method does not exist.
+This will return a L<Class::MOP::Method> instance for the specified
+C<$method_name>, or return undef if that method does not exist.
Unlike C<get_method> this will also look in the superclasses.
=item B<remove_method ($method_name)>
This will attempt to remove a given C<$method_name> from the class.
-It will return the CODE reference that it has removed, and will
-attempt to use B<Sub::Name> to clear the methods associated name.
+It will return the L<Class::MOP::Method> instance that it has removed,
+and will attempt to use B<Sub::Name> to clear the methods associated
+name.
=item B<get_method_list>
Use L<get_all_methods>, which is easier/better/faster. This method predates
L<Class::MOP::Method>.
+=item B<get_all_method_names>
+
+This will traverse the inheritance heirachy and return a list of all the
+applicable method names for this class. Duplicate names are removed, but the
+order the methods come out is not defined.
+
=item B<find_all_methods_by_name ($method_name)>
This will traverse the inheritence hierarchy and locate all methods
