More to the point, this is an outline of how to test the AI designer and is intended for the devs. There's not a lot here to interest the end user
Now, with that said...
There are a couple of pre-requisites. These instructions assume you're running MS Windows. If you're running linux (as I am) I assume you can sort out Ruby and Tk by yourself
Download and install both of those, and then check out the ai_shell files from https://projecthfsf.svn.sourceforge.net/svnroot/projecthfsf/trunk/ai_shell.
Then double-click on main.rb. That's it. Hopefully....
