    <title>Introduction to XScreenSaver</title>

    <para>
      The <application>XScreenSaver</application> package is a modular screen
      saver and locker for the X Window System. It is highly customizable and
      allows the use of any program that can draw on the root window as a
      display mode. The purpose of <application>XScreenSaver</application> is
      to display pretty pictures on your screen when it is not in use, in
      keeping with the philosophy that unattended monitors should always be
      doing something interesting, just like they do in the movies. However,
      <application>XScreenSaver</application> can also be used as a screen
      locker, to prevent others from using your terminal while you are away.
