+ <varlistentry><term><option>hold</option></term>
+ <listitem><para><literal>hold</literal> is used to mark a
+ package as hold 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 effected
+ by the <option>--filename</option> option.
