Specific TonegodGUI XML File - Where to Find?

I was wondering where I could find the XML file that gives, well, this.

Currently the one I’m using right now gives me only gray boxes.

Typing “TonegodGUI” into Google gave me this link as the first hit:

https://code.google.com/p/jmonkeyplatform-contributions/source/browse/trunk/tonegodGUI/src/tonegod/gui/tonegodGUI.xml

Note to maintainers: Tonego l dGUI.
