An almost identical clone of the original python-progressbar by Nilton Volpato, and available at:
https://pypi.python.org/pypi/progressbar/2.2
This version only differs from the original in that it uses relative package imports instead of absolute imports, which is necessary for the module to work under Python 3.3.
The module is available from PyPI so you just need to run:
pip install progressbar33
You can also install the latest version directly from github:
pip install git+https://github.com/germangh/python-progressbar
