# Some code taken from `nickserv.pl' for convenience.
# Credits Sami Haahtinen / ZaNaGa
#
# Don't forget to create the necessary chatnets in your irssi config file.
#
# Example:
# ....
# {
# address = "irc.undernet.org";
# chatnet = "Undernet";
# port = "6668";
# autoconnect = no;
# }
# .....
#
#
# Then connect with the server like this:
# /server undernet (or set autoconnect to yes)
# Make sure you fill in *all* necessary information without typos.
#
# Files you need to edit after first run:
# x.users -> For your x user/pw information.
# x.channels -> Channels to join after authing. (optional)
#
# Use /xrehash to reload if you edit the files.
#
# Var:
# my (%masks) -> See help there.
# Tested with X versions
# Undernet P10 Channel Services II Release 1.1pl7

Usage:
/auth <chatnet>
Settings:
/set xauth Shows current settings
/toggle xauth_autostart Toggle Auto Start
/toggle xauth_autojoin Toggle Auto Join
/toggle xauth_hiddenhost Toggle Hiddenhost (ircu u2.10.11+)
Rehashing settings and user/channel file:
/xrehash Run this after any changes
made to settings/files
/save Make settings permanent
