Hi Maurice, Thank you for your generous offer.
The PMC will conduct a vote as to whether to accept your donation. Meanwhile, please make sure your code does not have any dependencies on any non-Apache compatible licenses. Also, it would be great if you can make sure your donation is entirely source and will not contain any compiled code like third-party SWCs. Those will have to be downloaded from wherever they live. Finally, a Software Grant will have to be executed.
