/* Jabber Class Example
 * Copyright 2002-2005, Steve Blinch
 * http://code.blitzaffe.com
 * ============================================================================
 *
 * DETAILS
 *
 * Provides a very basic example of how to use class_Jabber.php.
 *
 * This example connects to a Jabber server, logs in, and waits until a message
 * is received from another contact.
 *
 * It then starts a countdown which, in sequence:
 *
 * 1) sends a "composing" event to the other contact (eg: "so-and-so is typing a message"),
 * 2) sends a "composing stopped" event,
 * 3) sends another "composing" event",
 * 4) sends a message to the other contact,
 * 5) logs out
 *
