Upgrading from ruby-wmii 0.2.x
==============================
The way to customize ruby-wmii has changed in 0.3.0 to simplify further
upgrades. Unfortunately, this modification, which will make things easier
from that moment on, means that you'll have to "port" your configuration to
the new style wmiirc-config.rb file. This is fairly easy and should take but
a few minutes.

The help message you'll get the first time you restart wmiirc explains how to
do it. You can read it again at any time by pressing MODKEY-a (ALT-a by
default) or the key combination that triggers the action menu in case it was
overriden, and selecting 'config-help'.
