# Description:
#
# This script allows to change your nick on the different networks you are
# connected, by appending or removing a suffix to your current nick on the
# network, based on the defined mask
# Command: /mnick [suffix]
# * if suffix is set and script enabled on network, will do a
#   /nick <current_nick><formatted_suffix>
# * if suffix is not set, will do a
#   /nick <previous_nick>
#
# Settings:
#  * plugins.var.perl.mnick.<network>_enabled : on/off
#  * plugins.var.perl.mnick.<network>_mask : default [%s]
#
# Example
# I'm CrazyCat on net1 and net3, GatoLoco on net2
#  * plugins.var.perl.mnick.net1_enabled : on
#  * plugins.var.perl.mnick.net1_mask : [%s]
#  * plugins.var.perl.mnick.net2_enabled : on
#  * plugins.var.perl.mnick.net2_mask : |%s
#  * plugins.var.perl.mnick.net3_enabled : off
#  * plugins.var.perl.mnick.net3_mask : [%s]
# /mnick AFK
# => CrazyCat[AFK] on net1, GatoLoco|AFK on net2, CrazyCat on net3
# /mnick
# => CrazyCat on net1 and net3, GatoLoco on net2
#
# History:
# 2016-05-23, CrazyCat <crazycat@c-p-f.org>:
#    version 0.3 : now, you can use alternate nick without doing
#    a /mnick before
# 2015-01-09, CrazyCat <crazycat@c-p-f.org>:
#    version 0.2 : corrected a stupid bug. Nick change is now only sent
#    to connected networks
# 2014-04-01, CrazyCat <crazycat@c-p-f.org>:
#    version 0.1 : first official version
