-// See Task first.  XmppClient is a parent task for XmppTasks.
-//
-// XmppClient is a task which is designed to be the parent task for
-// all tasks that depend on a single Xmpp connection.  If you want to,
-// for example, listen for subscription requests forever, then your
-// listener should be a task that is a child of the XmppClient that owns
-// the connection you are using.  XmppClient has all the utility methods
-// that basically drill through to XmppEngine.
-//
-// XmppClient is just a wrapper for XmppEngine, and if I were writing it
-// all over again, I would make XmppClient == XmppEngine.  Why?
-// XmppEngine needs tasks too, for example it has an XmppLoginTask which
-// should just be the same kind of Task instead of an XmppEngine specific
-// thing.  It would help do certain things like GAIA auth cleaner.
