This package contains the asynchat module as found in Python versions prior to
3.12. It is provided so that existing code relying on import asynchat is able
to continue being used without significant refactoring.

The module's source code is taken directly from the Python standard library.
The specific version of asynchat that is provided is the last update before the
addition of deprecation/removal warnings at import time, and is identical to
the version bundled with Python 3.9 (which was the last time the module was
meaningfully updated).
