<p>Presence and instant messenging are available from any <a href="http://www.jabber.org/about/overview.shtml">Jabber</a> client including <a href="http://www.google.com/talk/"> Google Talk</a>. Here is my current status :</p>
// The source code for my presence indicator is now available for whoever wants
// it. It is made possible by class.jabber.php, a Jabber library for PHP
// (http://cjphp.netflint.net/?section=about). I customized one of the examples
// provided with class.jabber.php
// (http://cjphp.netflint.net/?section=manual&sub=examples). It has many rough
// edges such as the user's name sprinkled across the markup code instead of
// being a proper parameter, or the page's presence being sent to the polled
// account instead of being hidden. And it is quite slow because it queries at
// load time. But I like it better than the example packaged with
// Exemple : http://jim.liotier.org/presence.php
// It basically does the job and I am therefore quite sure that there will be
// interested users. So this is the "early" part of "Release Early, Release
// Often". Take that hack, customize it, tweak it and generally improve it...
// And most of all please report back somewhere so that everyone can benefit.
// If anything is unclear to you, please be sure to report it to me :
// Jean-Marc Liotier
// Mail : firstname.lastname@example.org
// Jabber : email@example.com
