####  version: 0.1.7

####  inxi is a fork of infobash, the original bash sys info script by locsmif
####  As time permits functionality and recoding will occur.
####  
####  inxi, the universal, portable, system info script for irc.
####  Tested with Irssi, Xchat, Konversation, BitchX, KSirc, ircII,
####  Gaim/Pidgin, Weechat, KVIrc and Kopete.
