+@goops{} is a full object oriented system, with classes, objects,
+multiple inheritance, and generic functions with multi-method
+dispatch. Furthermore its implementation relies on a meta object
+protocol --- which means that @goops{}'s core operations are themselves
+defined as methods on relevant classes, and can be customised by
+overriding or redefining those methods.
