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

======Description:======
This hook is triggered whenever the client's idle time reaches the given
value, in minutes.  The idle time is reset when the client is given a
command.

======Parameters:======
|$0    |minutes idle |

=====Default Action:=====
If you don't suppress this event, the client will take no action.

======Examples:======
To automatically set the client away after being idle for 5 minutes:
   on ^idle "5" {
      away I'm not paying attention again...
   }

======Other Notes:======
Irc servers don't have the same notion of "idle" as the client does.  To
most servers, the client only becomes unidle by sending a message to a
channel or a person.
