## WARNING!! BAD ENGLISH BELOW :P
##
## This script is designed for those who have been using muh irc bouncer.
## Basicly this script just monitors the proxy module and if new client
## connects it sets you automatically back from away state and when client
## disconnects it sets you automatically away if you arent allready away.
##
## Other hand if you dont use irssi-proxy you still have a good reason to
## use this if you want to forward messages that come to you while
## you are away to email box.
## This is usefull for forwarding messages to an SMS-gateway ;)
##
## btw.. if you find any bugs or have any ideas for development of this
## script dont hesitate to send msg to BCOW@IrcNET
## or send email to anttip@n0-life.com
##
#### Version history:
# 0.1
# * basic functionality
# 0.2b
# * a patch from Wulf that gives a user ability to change the autoaway reason.
# * Added away_level parameter that gives you ability to control how many
# clients there can be connected to the irssi_proxy module before you are
# set away.
# * You arent set away when disconnecting from the irssi_proxy if you already
# are away. This means that your current away reason isn't changed.
# * Sends cumulated away messages back to the client when it connects to the
# irssi_proxy module.
# 0.2c
# * Fixes bug where cummulated messages weren't sent.
# * Code cleanup.
# * Text wrapping to standart 80x24 text console.
# * Added debug mode.
# * Added script modes.
# * Got rid of crappy irssi setings system.
# * New logging expansion capability, either time or line based.
# 0.2d
# * Micro fix to get back only when needed
# 0.2e
# * Changed default values for $config{script_mode} and $config{emailto} for IRC-only and a non-existing placeholder respectively.
#### To come / planned / wanted:
# * Make expansion system log several channels at once.
# * Make this script server based.
