This tutorial covers the process of using a Perl script to facilitate the notification of incoming Jabber messages when either a user is not present when the notification arrives or when a user is connected but does not wish to be disturbed. It also provides solutions to the problem of message traffic piling up when a user is away for an extended period of time.

The described approach takes advantage of the Net::Jabber Perl module and the Jabber XML structure for handling "presence". Five presence states are defined: Normal, Free for Chat, Away, Extended Away and Do Not Disturb. The tutorial steps the reader through development of small Perl scripts that utilize Extended Away and Do Not Disturb for a flexible solution. All Perl code is listed.
