+The XMPP plugin allows users to send and receive notices over the XMPP/Jabber/GTalk network.
+
+Installation
+============
+add "addPlugin('xmpp',
+ array('setting'=>'value', 'setting2'=>'value2', ...);"
+to the bottom of your config.php
+
+The daemon included with this plugin must be running. It will be started by
+the plugin along with their other daemons when you run scripts/startdaemons.sh.
+See the StatusNet README for more about queuing and daemons.
+
+Settings
+========
+user*: user part of the jid
+server*: server part of the jid
+resource: resource part of the jid
+port (5222): port on which to connect to the server
+encryption (true): use encryption on the connection
+host (same as server): host to connect to. Usually, you won't set this.
+debug (false): log extra debug info
+public: list of jid's that should get the public feed (firehose)
+
+* required
+default values are in (parenthesis)
+
+Example
+=======
+addPlugin('xmpp', array(
+ 'user=>'update',
+ 'server=>'identi.ca',
+ 'password'=>'...',
+ 'public'=>array('bob@aol.com', 'sue@google.com')
+));
