# thanks to Jilles Tjoelker <jilles@stack.nl>
# change "chatnet" to "tag"
# 18.05.2007 fix '-one' for SILC networks
#
#
# usage:
#
# put this script into your autorun directory and/or load it with
# /SCRIPT LOAD <name>
#
# there are 5 settings available:
#
# /set screen_away_active ON/OFF/TOGGLE
# /set screen_away_repeat <integer>
# /set screen_away_message <string>
# /set screen_away_window <string>
# /set screen_away_nick <string>
#
# active means, that you will be only set away/unaway, if this
# flag is set, default is ON
# repeat is the number of seconds, after the script will check the
# screen status again, default is 5 seconds
# message is the away message sent to the server, default: not here ...
# window is a window number or name, if set, the script will switch
# to this window, if it sets you away, default is '1'
# nick is the new nick, if the script goes away
# will only be used it not empty
#
# normal you should be able to rename the script to something other
# than 'screen_away' (as example, if you dont like the name) by simple
# changing the 'name' parameter in the %IRSSI hash at the top of this script
# variables
