+	  XScreenSaver is the standard screen saver collection shipped
+	  on most Linux and Unix systems running the X11 Window
+	  System.
+
+	  On X11 systems, XScreenSaver is two things: it is both a
+	  large collection of screen savers; and it is also the
+	  framework for blanking and locking the screen.
