Some users freak at the thought of a commandline, so I threw together a trivial GUI using whatever gui-from-shell tool is appropriate for the current desktop.
Unfortunately, that means the default action is to put up a gui, not show help. You have to say winetricks -h or the like to get help. It's ugly, so shoot me :-) As always, it's available at http://kegel.com/wine/winetricks and the svn repository is http://code.google.com/p/winezeug/
