+Summary
+=======
+
+psutil (python system and process utilities) is a cross-platform library for
+retrieving information on **running processes** and **system utilization**
+(CPU, memory, disks, network) in Python. It is useful mainly for **system
+monitoring**, **profiling and limiting process resources** and **management of
+running processes**. It implements many functionalities offered by command line
+tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice,
+ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports
+**Linux, Windows, OSX, FreeBSD** and **Sun Solaris**, both **32-bit** and
+**64-bit** architectures, with Python versions from **2.6 to 3.5** (users of
+Python 2.4 and 2.5 may use `2.1.3 <https://pypi.python.org/pypi?name=psutil&version=2.1.3&:action=files>`__ version).
+`PyPy <http://pypy.org/>`__ is also known to work.
