Install tkwinpm Tcl extension which can be found at
http://tkwinpm.googlecode.com.

As usually, copy this directory under the ~/.tkabber/plugins directory
so that you get a hierarchy like this:
  ~/.tkabber/plugins
  ~/.tkabber/plugins/green/
  ~/.tkabber/plugins/green/green.tcl

Restart Tkabber, to get the plugin loaded.
Visit the Cutsomize->Plugins->Green group of settings.
Consult the README file for the details about using this plugin.
