 <refsect1><title>Description</title>
   <para><command>apt-mark</command> will change whether a package has
   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>.
   </para>
     <variablelist>
     <varlistentry><term><option>auto</option></term>
	 <listitem><para><literal>auto</literal> is used to mark a
     package as being automatically installed, which will cause the
     package to be removed when no more manually installed packages
     depend on this package.
       </para></listitem>
       </varlistentry>

     <varlistentry><term><option>manual</option></term>
	 <listitem><para><literal>manual</literal> is used to mark a
     package as being manually installed, which will prevent the
     package from being automatically removed if no other packages
     depend on it.
       </para></listitem>
       </varlistentry>

       <varlistentry><term><option>hold</option></term>
	 <listitem><para><literal>hold</literal> is used to mark a
       package as held back, which will prevent the package from being
       automatically installed, upgraded or removed.
       The command is only a wrapper around <command>dpkg --set-selections</command>
       and the state is therefore maintained by &dpkg; and not affected
       by the <option>--file</option> option.
       </para></listitem>
       </varlistentry>

       <varlistentry><term><option>unhold</option></term>
	 <listitem><para><literal>unhold</literal> is used to cancel a
       previously set hold on a package to allow all actions again.
       </para></listitem>
       </varlistentry>

       <varlistentry><term><option>showauto</option></term>
	 <listitem><para><literal>showauto</literal> is used to print a
     list of automatically installed packages with each package on a new line.
     All automatically installed packages will be listed if no package is given.
     If packages are given only those which are automatically installed will be shown.
       </para></listitem>
       </varlistentry>

       <varlistentry><term><option>showmanual</option></term>
	 <listitem><para><literal>showmanual</literal> can be used in
     the same way as <literal>showauto</literal> except that it will print
     a list of manually installed packages instead.
       </para></listitem>
       </varlistentry>

       <varlistentry><term><option>showhold</option></term>
	 <listitem><para><literal>showhold</literal> is used to print a list
     of packages on hold in the same way as for the other show commands.
       </para></listitem>
       </varlistentry>
