+  ``singledispatch`` on all Python versions prior to 3.4 (This was an
+  optional dependency in prior versions of Tornado, and is now
+  mandatory), and ``backports_abc>=0.4`` on all versions prior to
+  3.5. These dependencies will be installed automatically when installing
+  with ``pip`` or ``setup.py install``. These dependencies will not
+  be required when running on Google App Engine.
