+34. Generic relations
+
+Generic relations let an object have a foreign key to any object through a
+content-type/object-id field. A ``GenericForeignKey`` field can point to any
+object, be it animal, vegetable, or mineral.
+
+The canonical example is tags (although this example implementation is *far*
+from complete).
