No problem, PyArabic is authored by Taha Zerrouki for the first time, and I made the araby_statistics with some fixes. I included it in Alfanous Project because it wasnt published that time : about 2010.  

Now its Available in PyPI with a newer version: https://pypi.python.org/pypi/PyArabic/0.4. Yet, its not hosted in any open source project hosts. I will ask Taha about creating a repo for it.
