				JAXL Instance
				=============
				``JAXL`` instance configure/manage other :ref:`sub-packages <jaxl-instance>`.
				It provides an event based callback methodology on various underlying object. Whenever required
				``JAXL`` instance will itself perform the configured defaults.

				Constructor options
				-------------------

				#. ``jid``
				#. ``pass``
				#. ``resource``

				If not passed Jaxl will use a random resource value

				#. ``auth_type``

				DIGEST-MD5, PLAIN (default), CRAM-MD5, ANONYMOUS, X-FACEBOOK-PLATFORM

				#. ``host``
				#. ``port``
				#. ``bosh_url``
				#. ``log_path``
				#. ``log_level``

				``JAXL_ERROR``, ``JAXL_WARNING``, ``JAXL_NOTICE``, ``JAXL_INFO`` (default), ``JAXL_DEBUG``

				#. ``fb_access_token``

				required when using X-FACEBOOK-PLATFORM auth mechanism

				#. ``fb_app_key``

				required when using X-FACEBOOK-PLATFORM auth mechanism

				#. ``force_tls``
				#. ``stream_context``
				#. ``priv_dir``

				Jaxl creates 4 directories names ``log``, ``tmp``, ``run`` and ``sock`` inside a private directory
				which defaults to ``JAXL_CWD.'/.jaxl'``. If this option is passed, it will overwrite default private
				directory.

				.. note::

				Jaxl currently doesn't check upon the permissions of passed ``priv_dir``. Make sure Jaxl library
				have sufficient permissions to create above mentioned directories.

				Available Event Callbacks
				-------------------------

				Following ``$ev`` are available on ``JAXL`` lifecycle for registering callbacks:

				#. ``on_connect``

				``JAXL`` instance has connected successfully

				#. ``on_connect_error``

				``JAXL`` instance failed to connect

				#. ``on_stream_start``

				``JAXL`` instance has successfully initiated XMPP stream with the jabber server

				#. ``on_stream_features``

				``JAXL`` instance has received supported stream features

				#. ``on_auth_success``

				authentication successful

				#. ``on_auth_failure``

				authentication failed

				#. ``on_presence_stanza``

				``JAXL`` instance has received a presence stanza

				#. ``on_{$type}_message``

				``JAXL`` instance has received a message stanza. ``$type`` can be ``chat``, ``groupchat``, ``headline``, ``normal``, ``error``

				#. ``on_stanza_id_{$id}``

				Useful when dealing with iq stanza. This event is fired when ``JAXL`` instance has received response to a particular
				xmpp stanza id

				#. ``on_{$name}_stanza``

				Useful when dealing with custom xmpp stanza

				#. ``on_disconnect``

				``JAXL`` instance has disconnected from the jabber server

				Available Methods
				-----------------

				Following methods are available on initialized ``JAXL`` instance object:

				#. ``get_pid_file_path()``

				returns path of ``JAXL`` instance pid file

				#. ``get_sock_file_path()``

				returns path to ``JAXL`` ipc unix socket domain

				#. ``require_xep($xeps=array())``

				autoload and initialize passed XEP's

				#. ``add_cb($ev, $cb, $pri=1)``

				add a callback to function ``$cb`` on event ``$ev``, returns a reference of added callback

				#. ``del_cb($ref)``

				delete previously registered event callback

				#. ``set_status($status, $show, $priority)``

				send a presence status stanza

				#. ``send_chat_msg($to, $body, $thread=null, $subject=null)``

				send a message stanza of type chat

				#. ``get_vcard($jid=null, $cb=null)``

				fetch vcard for bare ``$jid``, passed ``$cb`` will be called with received vcard stanza

				#. ``get_roster($cb=null)``

				fetch roster list of connected jabber client, passed ``$cb`` will be called with received roster stanza

				#. ``start($opts=array())``

				start ``JAXL`` instance with support for IPC and remote debugging

				#. ``send($stanza)``

				send an instance of JAXLXml packet over connected socket

				#. ``send_raw($data)``
