description:
  daemontools is a collection of tools for managing UNIX services.

  supervise monitors a service. It starts the service and restarts the service
  if it dies. Setting up a new service is easy: all supervise needs is a directory
  with a run script that runs the service.

  multilog saves error messages to one or more logs. It optionally timestamps each
  line and, for each log, includes or excludes lines matching specified patterns.
  It automatically rotates logs to limit the amount of disk space used.
  If the disk fills up, it pauses and tries again, without losing any data.

  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 3.4** (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.

  A lot of time and effort went into making psutil as it is right now.
  If you feel psutil is useful to you or your business and want to support its future development please consider donating me (`Giampaolo Rodola' <http://grodola.blogspot.com/p/about.html>`_) some money.
  I only ask for a small donation, but of course I appreciate any amount.

description:
  ZVBI provides functions to capture and decode VBI data. The vertical blanking
  interval (VBI) is an interval in a television signal that temporarily suspends
  transmission of the signal for the electron gun to move back up to the first
  line of the television screen to trace the next screen field. The vertical
  blanking interval can be used to carry data, since anything sent during the VBI
  would naturally not be displayed; various test signals, closed captioning, and
  other digital data can be sent during this time period.
