+%description
+Typing Extensions - Backported and Experimental Type Hints for Python.
+The typing module was added to the standard library in Python 3.5, but many new features have been added to the module since then.
+This means users of Python 3.5 - 3.6 who are unable to upgrade will not be able to take advantage of new types added to the typing
+module, such as typing.Protocol or typing.TypedDict.
+The typing_extensions module contains backports of these changes. Experimental types that will eventually be added to the typing
+module are also included in typing_extensions, such as typing.ParamSpec and typing.TypeGuard.
