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

Restart Tkabber, to get the plugin loaded.

Activate "Tkabber->Services->Snoop status messages" main menu item
to open the window which will collect the status messages.

Consult the README file for the details about using this plugin.
