 %description
-Mock is a Python module that provides a core mock class. It removes the need
-to create a host of stubs throughout your test suite. After performing an
-action, you can make assertions about which methods / attributes were used and
-arguments they were called with. You can also specify return values and set
-needed attributes in the normal way.
+This is a deprecated package.
+
+The mock module is now part of the Python standard library,
+available as unittest.mock in Python 3.3 onwards.
