+Typing Extensions – Backported and Experimental Type Hints for Python
+
+The typing_extensions module serves two related purposes:
+
+- Enable use of new type system features on older Python versions. For
+  example, `typing.TypeGuard` is new in Python 3.10, but
+  typing_extensions allows users on previous Python versions to use it
+  too.
+- Enable experimentation with new type system PEPs before they are
+  accepted and added to the typing module.
+
+typing_extensions is treated specially by static type checkers such as
+mypy and pyright. Objects defined in typing_extensions are treated the
+same way as equivalent forms in typing.

+# 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.
