# grumble.pl provides sane integration of Irssi with Growl [http://growl.info/]
# and Mumbles [http://www.mumbles-project.org/]. These programs both support the
# Growl network protocol that the Perl module Net::Growl uses to communicate.
#
# This script supports multiple targets, each with a potentially unique Growl
# password.
#
# SETTINGS
# Targets are specified in the "grumble_targets" setting:
#   /set grumble_targets localhost:mypass
#     sends messages to an instance running on localhost with password "mypass"
#   /set grumble_targets localhost:mypass othermachine:otherpass
#     sends messages to two separate machines with different passwords
#
# To turn on/off notifications while /away, toggle the setting
# 'grumble_notify_when_away'. Default: OFF.
#
# To enable/disable notifications for the active window, toggle the setting
# 'grumble_notify_for_active_window'. Default: ON.
