   been marked as being automatically installed.
   </para>
   <para>
     When you request that a package is installed, and as a result
     other packages are installed to satisfy its dependencies, the
     dependencies are marked as being automatically installed.  Once
     these automatically installed packages are no longer depended on
     by any manually installed packages, they will be removed by e.g.
     <command>apt-get</command> or <command>aptitude</command>.
