+       These two options affect how the objects contained in the pack are
        stored using delta compression. The objects are first internally
        sorted by type, size and optionally names and compared against the
        other objects within `--window` to see if using delta compression saves
        space. `--depth` limits the maximum delta depth; making it too deep
        affects the performance on the unpacker side, because delta data needs
        to be applied that many times to get to the necessary object.
+       The default value for both --window and --depth is 10.

+Configuration
+-------------
+
+When configuration variable `repack.UseDeltaBaseOffset` is set
+for the repository, 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 (and including) v1.4.3; do not set
+the variable in a repository that older version of git needs to
+be able to read (this includes repositories from which packs can
+be copied out over http or rsync, and people who obtained packs
+that way can try to use older git with it).
