Download patch.py and run it with Python. It is a self-contained module without external dependencies.
patch.py diff.patch

Installation
patch.py is self sufficient. You can copy it into your repository
and use it from here. This setup will always be repeatable. But if
you need to add patch module as a dependency, make sure to use strict
specifiers to avoid hitting an API break when version 2 is released:
pip install "patch==1.*"
