            Developer's Certificate of Origin 1.1

            By making a contribution to this project, I certify that:

            (a) The contribution was created in whole or in part by me and I

            (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) 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.

A Poky contributions tree (poky-contrib, git://git.yoctoproject.org/poky-contrib.git) exists for people to stage contributions in, for regular contributors. If people desire such access, please ask on the mailing list. Usually access will be given to anyone with a proven track record of good patches.
