-NAME
-----
-git-repack - Pack unpacked objects in a repository
-
-
-SYNOPSIS
---------
-[verse]
-'git repack' [-a] [-A] [-d] [-f] [-F] [-l] [-n] [-q] [-b] [--window=<n>] [--depth=<n>] [--threads=<n>] [--keep-pack=<pack-name>]
-
-DESCRIPTION
------------
-
-This command is used to combine all objects that do not currently
-reside in a "pack", into a pack.  It can also be used to re-organize
-existing packs into a single, more efficient pack.
-
-A pack is a collection of objects, individually compressed, with
-delta compression applied, stored in a single file, with an
-associated index file.
-
-Packs are used to reduce the load on mirror systems, backup
-engines, disk storage, etc.
-
-OPTIONS
--------
-
--a::
-	Instead of incrementally packing the unpacked objects,
-	pack everything referenced into a single pack.
-	Especially useful when packing a repository that is used
-	for private development. Use
-	with `-d`.  This will clean up the objects that `git prune`
-	leaves behind, but `git fsck --full --dangling` shows as
-	dangling.
-+
-Note that users fetching over dumb protocols will have to fetch the
-whole new pack in order to get any contained object, no matter how many
-other objects in that pack they already have locally.
-+
-Promisor packfiles are repacked separately: if there are packfiles that
-have an associated ".promisor" file, these packfiles will be repacked
-into another separate pack, and an empty ".promisor" file corresponding
-to the new separate pack will be written.
-
--A::
-	Same as `-a`, unless `-d` is used.  Then any unreachable
-	objects in a previous pack become loose, unpacked objects,
-	instead of being left in the old pack.  Unreachable objects
-	are never intentionally added to a pack, even when repacking.
-	This option prevents unreachable objects from being immediately
-	deleted by way of being left in the old pack and then
-	removed.  Instead, the loose unreachable objects
-	will be pruned according to normal expiry rules
-	with the next 'git gc' invocation. See linkgit:git-gc[1].
-
--d::
-	After packing, if the newly created packs make some
-	existing packs redundant, remove the redundant packs.
-	Also run  'git prune-packed' to remove redundant
-	loose object files.
-
--l::
-	Pass the `--local` option to 'git pack-objects'. See
-	linkgit:git-pack-objects[1].
-
--f::
-	Pass the `--no-reuse-delta` option to `git-pack-objects`, see
-	linkgit:git-pack-objects[1].
-
--F::
-	Pass the `--no-reuse-object` option to `git-pack-objects`, see
-	linkgit:git-pack-objects[1].
-
--q::
-	Pass the `-q` option to 'git pack-objects'. See
-	linkgit:git-pack-objects[1].
-
--n::
-	Do not update the server information with
-	'git update-server-info'.  This option skips
-	updating local catalog files needed to publish
-	this repository (or a direct copy of it)
-	over HTTP or FTP.  See linkgit:git-update-server-info[1].
-
---window=<n>::
---depth=<n>::
-	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 --window is 10 and --depth is 50. The maximum
-depth is 4095.
-
---threads=<n>::
-	This option is passed through to `git pack-objects`.
-
---window-memory=<n>::
-	This option provides an additional limit on top of `--window`;
-	the window size will dynamically scale down so as to not take
-	up more than '<n>' bytes in memory.  This is useful in
-	repositories with a mix of large and small objects to not run
-	out of memory with a large window, but still be able to take
-	advantage of the large window for the smaller objects.  The
-	size can be suffixed with "k", "m", or "g".
-	`--window-memory=0` makes memory usage unlimited.  The default
-	is taken from the `pack.windowMemory` configuration variable.
-	Note that the actual memory usage will be the limit multiplied
-	by the number of threads used by linkgit:git-pack-objects[1].
-
---max-pack-size=<n>::
-	Maximum size of each output pack file. The size can be suffixed with
-	"k", "m", or "g". The minimum size allowed is limited to 1 MiB.
-	If specified, multiple packfiles may be created, which also
-	prevents the creation of a bitmap index.
-	The default is unlimited, unless the config variable
-	`pack.packSizeLimit` is set.
-
--b::
---write-bitmap-index::
-	Write a reachability bitmap index as part of the repack. This
-	only makes sense when used with `-a` or `-A`, as the bitmaps
-	must be able to refer to all reachable objects. This option
-	overrides the setting of `repack.writeBitmaps`.  This option
-	has no effect if multiple packfiles are created.
-
---pack-kept-objects::
-	Include objects in `.keep` files when repacking.  Note that we
-	still do not delete `.keep` packs after `pack-objects` finishes.
-	This means that we may duplicate objects, but this makes the
-	option safe to use when there are concurrent pushes or fetches.
-	This option is generally only useful if you are writing bitmaps
-	with `-b` or `repack.writeBitmaps`, as it ensures that the
-	bitmapped packfile has the necessary objects.
-
---keep-pack=<pack-name>::
-	Exclude the given pack from repacking. This is the equivalent
-	of having `.keep` file on the pack. `<pack-name>` is the
-	pack file name without leading directory (e.g. `pack-123.pack`).
-	The option could be specified multiple times to keep multiple
-	packs.
-
---unpack-unreachable=<when>::
-	When loosening unreachable objects, do not bother loosening any
-	objects older than `<when>`. This can be used to optimize out
-	the write of any objects that would be immediately pruned by
-	a follow-up `git prune`.
-
--k::
---keep-unreachable::
-	When used with `-ad`, any unreachable objects from existing
-	packs will be appended to the end of the packfile instead of
-	being removed. In addition, any unreachable loose objects will
-	be packed (and their loose counterparts removed).
-
--i::
---delta-islands::
-	Pass the `--delta-islands` option to `git-pack-objects`, see
-	linkgit:git-pack-objects[1].
-
-Configuration
--------------
-
-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 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.
