walnut

walnut is an APACHE licensed library written in Python designed to provide a simple and pythonic way to parse the /proc/cpuinfo file on LINUX based systems.

Installation:

From source use

	$ python setup.py install

or install from PyPi

	$ pip install walnut

Documentation:

• Basic use:
