psutil 2.1.3 is replacing psutil 1.0.1. There are numerous bug fixes and feature enhancements in psutil worth obtaining. Source code was obtained from https://pypi.python.org/packages/source/p/psutil/psutil-2.1.3.tar.gz and uncompressed into python/psutil without modification except for the removal of the egg-info directory and the .travis.yml file.
About
=====
This directory contains the reStructuredText (reST) sources to the psutil
documentation. You don't need to build them yourself, prebuilt versions are
available at https://pythonhosted.org/psutil/.
In case you want, you need to install sphinx first:
$ pip install sphinx
Then run:
$ make html
You'll then have an HTML version of the doc at _build/html/index.html.
