  repack.usedeltabaseoffset::
-       Allow linkgit:git-repack[1] to create packs that uses
-       delta-base offset.  Defaults to false.
+       By default, linkgit:git-repack[1] creates packs that use
+       delta-base offset. If you need to share your repository with
+       git older than version 1.4.4, either directly or via a dumb
+       protocol such as http, then you need to set this option to
+       "false" and repack. Access from old git versions over the
+       native protocol are unaffected by this option.
