Tkabber starpack is a standalone executable file that contains Tkabber, Tcl/Tk, packages required to run Tkabber and several Tcl/Tk extensions.
With this distribution you do not need to install anything on your computer to use Tkabber (so it's ideal for putting on USB sticks).
It's also really lightweight — about 5 megabytes of download.
Current version of Tkabber-Starpack is 0.11.1. It is the recommended download.
There's no 0.11.1 starpack for Linux prepared yet due to technical reasons. We will try to put it up, eventually.
