+Typing Extensions – Backported and Experimental Type Hints for Python
+
+The typing module was added to the standard library in Python 3.5 on a
+provisional basis and will no longer be provisional in Python 3.7. However,
+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.Text
+or typing.Coroutine.
+
+The typing_extensions module contains both backports of these changes as well
+as experimental types that will eventually be added to the typing module, such
+as Protocol or TypedDict.
+
+Users of other Python versions should continue to install and use the typing
+module from PyPi instead of using this one unless specifically writing code
+that must be compatible with multiple Python versions or requires experimental
+types.
+
+Optional:
+
+python3

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
