+By default, the command passes `--delta-base-offset` option to
+'git pack-objects'; this typically results in slightly smaller packs,
+but the generated packs are incompatible with versions of Git older than
+version 1.4.4. If you need to share your repository with such ancient Git
+versions, either directly or via the dumb http or rsync protocol, then you
+need to set the configuration variable `repack.UseDeltaBaseOffset` to
+"false" and repack. Access from old Git versions over the native protocol
+is unaffected by this option as the conversion is performed on the fly
+as needed in that case.
