    <para>
      The <application>GPM</application> (General Purpose Mouse daemon)
      package contains a mouse server for the console and
      <command>xterm</command>. It not only provides cut and paste support
      generally, but its library component is used by various software such as
      <application>Links</application> to provide mouse support to the
      application.  It is useful on desktops, especially if following (Beyond)
      Linux From Scratch instructions; it's often much easier (and less error
      prone) to cut and paste between two console windows than to type
      everything by hand!
