    We'll want to add a short explanation (and in the documentation). Links to the original
paper and other explanatory documents would be helpful references. We don't include author
names, dates, references to tickets, etc. since these are provided by git annotations.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
