* quiet

A simple package to disconnect from the online world for a while, possibly reconnecting later. Any interuptions or distractions which occur once the command is run are guaranteed to be local.

* disconnection

``M-x quiet`` will disconnect from the network, optionally reconecting after a certain time.

the function ``quiet`` can be used anywhere in emacs where lack of network access could be seen a as a feature, e.g.  as a mode-hook (or with ``defadvice``) to your preferred distraction free writing environment. 

* reconection

 ``M-x quiet-reconnect`` will manually reconect to the network, however you can enable a timer to automatically reconnect by setting ``quiet-timer`` to a number of minutes. e.g. ``(setq quiet-timer 60)`` will let ``quiet`` to reconnect after one hour. if  ``quiet-timer`` is set to 0 it won't reconnect automatically.

* network interfaces

you may want to ``customize`` or ``setq`` ``quiet-disconnect`` and ``quiet-connect`` to the appropriate shell commands to turn your network (or single interface) on or off.
