GPL Additional Notes

Linking CPG Dragonfly™ CMS statically or dynamically with other modules is making a combined work based on CPG Dragonfly CMS.  Thus, the terms and conditions of the GNU General Public License cover the whole combination.

As a special exception, the copyright holders of CPG Dragonfly CMS give you permission to link CPG Dragonfly CMS with independent modules that communicate with CPG Dragonfly CMS solely through the CPG-Core interface, regardless of the license terms of these independent modules, and to copy and distribute the resulting combined work under terms of your choice, provided that every copy of the combined work is accompanied by a complete copy of the source code of CPG Dragonfly CMS (the version of CPG Dragonfly CMS used to produce the combined work), being distributed under the terms of the GNU General Public License plus this exception.  An independent module is a module which is not derived from or based on CPG Dragonfly CMS.

Note that people who make modified versions of CPG Dragonfly CMS are not obligated to grant this special exception for their modified versions; it is their choice whether to do so.  The GNU General Public License gives permission to release a modified version without this exception; this exception also makes it possible to release a modified version which carries forward this exception.
