+repack.useDeltaBaseOffset::
+	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.
+
+repack.packKeptObjects::
+	If set to true, makes `git repack` act as if
+	`--pack-kept-objects` was passed. See linkgit:git-repack[1] for
+	details. Defaults to `false` normally, but `true` if a bitmap
+	index is being written (either via `--write-bitmap-index` or
+	`repack.writeBitmaps`).
+
+repack.useDeltaIslands::
+	If set to true, makes `git repack` act as if `--delta-islands`
+	was passed. Defaults to `false`.
+
+repack.writeBitmaps::
+	When true, git will write a bitmap index when packing all
+	objects to disk (e.g., when `git repack -a` is run).  This
+	index can speed up the "counting objects" phase of subsequent
+	packs created for clones and fetches, at the cost of some disk
+	space and extra time spent on the initial repack.  This has
+	no effect if multiple packfiles are created.
+	Defaults to true on bare repos, false otherwise.
