To improve tracking of contributions to this project we will use a process modeled on the modified DCO 1.1 and use a "sign-off" procedure on patches that are being emailed around or contributed in any other way.
The sign-off is a simple line within the pull requests comments section, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple, if you can certify the below:
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or
(b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source License and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or
(c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.
(d) The contribution is made free of any other party's intellectual property claims or rights.
(e) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
Then you just add a line saying:
