Developer's Certificate of Origin
The DCO was fetched from https://developercertificate.org/ on Feb 4, 2019. DCO-1.1.txt is a verbatim copy of it.
We should carry a copy of this legal document to be explicit on what wording we refer to. A link to the URL is not enough, because it may go stale or change contents without notice.
This clarifies on what the S-o-b actually means. The meaning itself is the same as before.
