DESCRIPTION_SHORT="Automatically run a command (such as poweroff) once certain conditions are met."

DESCRIPTION_LONG="[GUI configurator available - Search for 'autopoweroff']

Autopoweroff is a daemon that is started at boot time, and which function is
to run a command at a specific time, but only if some conditions are met.
Originally, this application would only shutdown the computer, thus its name,
but now it can suspend, hibernate, or run any custom command provided by the
user.

This software is meant for the Linux operating system only.  It should work on
any modern Linux distribution.  DEB and RPM packages are available.

The computer will execute the command (suspend by default) if all the above
conditions are met:

* Any hosts that the computer is dependent on is not answering ping anymore.
* No keyboard or mouse activity has been detected on the computer for a while.
* The CPU usage falls below a threshold for a period of at least 1s.
* The user has not disabled Autopoweroff.


Cloud use
--------------------------------------------------

Autopoweroff can be used on a cloud instance which could be shutdown
automatically as soon as the CPU usage falls below a threshold (after heavy
processing is over), thus saving cost of keeping the cloud instance up.


Home use
--------------------------------------------------

Another good use of Autopoweroff is at home, on a firewall/router server.
You can setup Autopoweroff to suspend/shutdown the server every evening at
say, 22:00.  However, your server might serve other computers in your home.
Autopoweroff will shutdown the server after 22:00 only if no other computer
on the network is responding to <code>ping</code>.  For example, if at 22:43
you are still working on your thin client in the living room, the server in
your baseman will remain up.  As soon as you shutdown the workstation, the
server will go down.

The server can boot automatically every morning by setting its UEFI
properly.  Autopoweroff has nothing to do with this process.  But with
this setting, your home server does not need to run 24/7.  The advantages
such a setting offers are:

  - Increase security.  Nobody can hack your server while its suspended, in
    hibernation or shutdown.
  - Save electricity and curb down heat generation.
  - Cut down noise.  A shutdown server does not produce any noise.
  - Avoid the hassle of having to shut down and start up the server manually.
