/* XScreenSaver uses XML files to describe the user interface for configuring
   the various screen savers.  These files live in .../hacks/config/ and
   say relatively high level things like: "there should be a checkbox
   labelled "Leave Trails", and when it is checked, add the option '-trails'
   to the command line when launching the program."

   This code reads that XML and constructs a Cocoa interface from it.
   The Cocoa controls are hooked up to NSUserDefaultsController to save
   those settings into the MacOS preferences system.  The Cocoa preferences
   names are the same as the resource names specified in the screenhack's
   'options' array (we use that array to map the command line switches
   specified in the XML to the resource names to use).
