[[!tag type/special-purpose]]
This plugin will configure your wiki to send IRC notifications using the [irker](http://www.catb.org/esr/irker/) notification bot.
It is fairly simple and requires no configuration but installation of the irker package. For template configuration, patches from [Debian bug #824512](https://bugs.debian.org/824512) are necessary. Note that they have been factored into irker 2.18.
