+Configurable pristine checksum kind in a working copy
+-----------------------------------------------------
+
+The implementation on the branch allows creating working copies that use a
+checksum kind other than SHA-1.
+
+The checksum kind is persisted in the settings table. Upgraded working copies
+of the older formats will have SHA-1 recorded as their pristine checksum kind
+and will continue to use it for compatibility. Newly created working copies
+of the latest format (with --compatible-version=1.15 or --store-pristine=no),
+as currently implemented, will use the new pristine checksum kind.
+
+Currently, as a proof-of-concept, the branch uses salted SHA-1 as the new
+pristine checksum kind. For the production-ready state, we could support
+using multiple new checksum types such as SHA-256. That could be useful
+for future compatibility, because if we encounter any issues with one
+checksum kind, we could then switch to a different kind without having
+to change the working copy format.
