        <description>Regular expression naming plugin directory names to
            include. Any plugin not matching this expression is excluded.
            In any case you need at least include the nutch-extensionpoints plugin. By
            default Nutch includes crawling just HTML and plain text via HTTP,
            and basic indexing and search plugins. In order to use HTTPS please enable
            protocol-httpclient, but be aware of possible intermittent problems with the
            underlying commons-httpclient library.
