12 /* XScreenSaver uses XML files to describe the user interface for configuring
13 the various screen savers. These files live in .../hacks/config/ and
14 say relatively high level things like: "there should be a checkbox
15 labelled "Leave Trails", and when it is checked, add the option '-trails'
16 to the command line when launching the program."
18 This code reads that XML and constructs a Cocoa interface from it.
19 The Cocoa controls are hooked up to NSUserDefaultsController to save
20 those settings into the MacOS preferences system. The Cocoa preferences
21 names are the same as the resource names specified in the screenhack's
22 'options' array (we use that array to map the command line switches
23 specified in the XML to the resource names to use).
