	Author: Badlop
	Module for ejabberd 0.7.5 or newer


	DESCRIPTION
	-----------

This module sniffs all the XMPP traffic send and received by ejabberd,
both internally and externally transmitted. It logs the XMPP packets
to a XML formatted file. It's posible to filter transmitted packets 
by orientation, stanza and direction. It's possible to configure the 
file rotation rules and intervals.

This module reuses code from mod_log_forensic, mod_stats2file, mod_muc_log
