* ECLIPSE with only the license terms in place for ECLIPSE applying to
* ECLIPSE and the GNU GPL Version 3 applying for KNIME, provided the

* Additional permission relating to nodes for KNIME that extend the Node
* Extension (and in particular that are based on subclasses of NodeModel,
* NodeDialog, and NodeView) and that only interoperate with KNIME through

* Nodes are deemed to be separate and independent programs and to not be

* license Nodes under the License, and you are granted a license to
