Project Dune:Your rights and restrictions

From PDune

All of Project Dune is available under the General Public License v2 (GPLv2).

Distribution License

Note that the GPL license is a distribution license and does not limit your abilities to modify the source code for personal use (for example, modifications and/or additions to the DuneCustom package). As long as you are not re-distributing the binaries or source code that you modify or include, you are legally allowed to modify anything in the project. In a nutshell: You are free to use the project's source code for your internal use.

However, the license does not allow you to link with any software or library provided in the project and then re-distribute those libraries under a license incompatible with the GPL. If you do intend to integrate your commercial solution with Project Dune, we'd still like to talk to you, as we can negotiate a commercial license for this software. Whether end customers purchase this commercial license or you buy the rights yourself is irrelevant. As long you make it clear enough to the user that such obligations exist, we are happy. Please contact one of the project administrators if you need to find out more information.

Consultancy and Work For Hire

Should you are provide consultancy or integration work and the client has requested you to customize this project, you may be required to apply for a commercial license. This depends if you actually release your modifications to the client and under what license you wish to do that. Also, if you do not wish to distribute the modifications under the GPL, you only use the project in-house, but the work is not executed in the contract as "work for hire", you need to request a commercial license.
