======Synopsis:======
[[on]] [<modes>]exit [<serial#>] [-|^]<match> { <action> }

======Description:======
This hook is triggered when the client is about to exit normally (from the
[[QUIT]] command, etc.).  It is mostly useful for doing cleanup before exiting,
such as saving any current settings.  It cannot be used to trap the [[QUIT]]
command; the client will exit immediately after this hook is triggered..

======Parameters:======
|$* | Your quit message |

======Default behavior:======
If you do not suppress this event, the client does nothing.
The client immediately begins shutdown procedures no matter what
you do or don't do with this event.

======Examples:======
Save current settings before exiting:
   on ^exit "*" {
      save all
      echo Now exiting ircII-${J}...
   }
