Q:

Looking for cross-platform rsync-like functionality in python, such as rsync.py

I am implementing backup scripts in python. I'm trying to keep things cross platform. I hear there is a python based rsync implementation: http://pypi.python.org/pypi/rsync.py
But I can't seem to find it anywhere. All of the download links I find are dead. Does anyone know where I could find the rsync.py program?
At the moment I am using unison for Windows but I would like to try rsync.py
