        Whether to enable k3b, the KDE disk burning application.

        Additionally to installing <package>k3b</package> enabling this will
        add <literal>setuid</literal> wrappers in <literal>/run/wrappers/bin</literal>

        run you must manually configure the path of <package>cdrdae</package> and
        <package>cdrecord</package> to correspond to the appropriate paths under
        <literal>/run/wrappers/bin</literal> in the "Setup External Programs" menu.
