How to document contributions in bzr

By default add to bzr the following in the global comment for each contribution:

Patch:    Name, url or from where we got the patch
Author:   ....
License:  MCA or BSD
Reviewer: ....

For those cases this is not done, please add to this page a short line for each push into MariaDB that includes code from contributors not employed by Monty Program Ab. The purpose of this is to properly track that all such patches are submitted either under MCA or BSD-new and to ensure that the developer gets credit for his work.


Feature/Patch name
* Author(s)
* Author has signed MCA on "date" | Patch was licensed under BSD

(Please enhance the example with anything that makes sense.)
