-             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

-   -  Provide a single-line summary of the change and, if more
-      explanation is needed, provide more detail in the description of the
-      commit. This summary is typically viewable in the "shortlist" of
-      changes. Thus, providing something short and descriptive that
-      gives the reader a summary of the change is useful when viewing a
-      list of many commits. You should prefix this short description
-      with the recipe name (if changing a recipe), or else with the
-      short form path to the file being changed.
-
-      .. note::
-
-         To find a suitable prefix for the commit summary, a good idea
-         is to look for prefixes used in previous commits touching the
-         same files or directories::
-
-            git log --oneline <paths>
-
-   -  For the commit description, provide detailed information
-      that describes what you changed, why you made the change, and the
-      approach you used. It might also be helpful if you mention how you
-      tested the change. Provide as much detail as you can in the commit
-      description.
-
-      .. note::
-
-         If the single line summary is enough to describe a simple
-         change, the commit description can be left empty.
-
-   -  If the change addresses a specific bug or issue that is associated
-      with a bug-tracking ID, include a reference to that ID in the body of the
-      commit message. For example, the Yocto Project uses a
-      specific convention for bug references --- any commit that addresses
-      a specific bug should use the following form for the body of the commit
-      message. Be sure to use the actual bug-tracking ID from
-      Bugzilla for bug-id::
