I didn't realize that WineSetupTk was depreciated when I wrote. I just want to play StarCraft and Diablo and was finding the documentation a bit hard to follow. (I couldn't find my .wine.conf file and got stuck, that's why I thought I needed WineSetupTk.) I will poke at it a bit myself and if I can figure out how it works, maybe then I can make a suggestion or two for clearing up the documentation. (Who maintains the documentation, BTW?)
OK, what specifically were you trying to configure. Our aim (obviously) is that StarCraft and such should work out of the box with no configuration needed.
