Summary
=======
psutil is a module providing an interface for retrieving information on all
running processes and system utilization (CPU, memory, disks, network, users) in
a portable way by using Python, implementing many functionalities offered by
command line tools such as: **ps, top, df, kill, free, lsof, free, netstat,
ifconfig, nice, ionice, iostat, iotop, uptime, pidof, tty, who, taskset, pmap**.
It currently supports **Linux**, **Windows**, **OSX**, **FreeBSD**,
**Sun Solaris** both **32-bit** and **64-bit** with Python versions from **2.4**
to **3.3** by using a single code base.
