+=head1 NAME
+
+Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods
+
+=head1 VERSION
+
+version 2.2207
+
+=head1 DESCRIPTION
+
+This class implements method overriding logic for the L<Moose>
+C<override> keyword.
+
+The overriding subroutine's parent will be invoked explicitly using
+the C<super> keyword from the parent class's method definition.
+
+=head1 METHODS
+
+=head2 Moose::Meta::Method::Overridden->new(%options)
+
+This constructs a new object. It accepts the following options:
+
+=over 4
+
+=item * class
+
+The metaclass object for the class in which the override is being
+declared. This option is required.
+
+=item * name
+
+The name of the method which we are overriding. This method must exist
+in one of the class's superclasses. This option is required.
+
+=item * method
+
+The subroutine reference which implements the overriding. This option
+is required.
