+    ``match_equality`` allows Hamcrest matchers to be used in libraries that
+    are not Hamcrest-aware. They might use the equality operator::
+
+        assert match_equality(matcher) == object
+
+    Or they might provide a method that uses equality for its test::
+
+        library.method_that_tests_eq(match_equality(matcher))
+
+    One concrete example is integrating with the ``assert_called_with`` methods
+    in Michael Foord's `mock <http://www.voidspace.org.uk/python/mock/>`_
+    library.
