-//! The XMPP connection engine.
-//! This engine implements the client side of the 'core' XMPP protocol.
-//! To use it, register an XmppOutputHandler to handle socket output
-//! and pass socket input to HandleInput.  Then application code can
-//! set up the connection with a user, password, and other settings,
-//! and then call Connect() to initiate the connection.
-//! An application can listen for events and receive stanzas by
-//! registering an XmppStanzaHandler via AddStanzaHandler().
