Reads list of objects from the standard input, and writes a packed
archive with specified base-name, or to the standard output.

The 'git unpack-objects' command can read the packed archive and
expand the objects contained in the pack into "one-file
commands when a pack is created on-the-fly for efficient network
transport by their peers.

OPTIONS
-------
--all::
This implies `--revs`. In addition to the list of
revision arguments read from the standard input, pretend
- as if all refs under `$GIT_DIR/refs` are specified to be
+ as if all refs under `refs/` are specified to be
included.
--include-tag::
reference was included in the resulting packfile. This
can be useful to send new tags to native git clients.
---window=[N]::
---depth=[N]::
+--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
times to get to the necessary object.
The default value for --window is 10 and --depth is 50.
---window-memory=[N]::
+--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
+ 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
default.
--max-pack-size=<n>::
- Maximum size of each output packfile, expressed in MiB.
+ 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.
The default is unlimited, unless the config variable
`pack.packSizeLimit` is set.
--honor-pack-keep::
This flag causes an object already in a local pack that
- has a .keep file to be ignored, even if it appears in the
- standard input.
+ has a .keep file to be ignored, even if it it would have
+ otherwise been packed.
--incremental::
- This flag causes an object already in a pack ignored
- even if it appears in the standard input.
+ This flag causes an object already in a pack to be ignored
+ even if it would have otherwise been packed.
--local::
- This flag is similar to `--incremental`; instead of
- ignoring all packed objects, it only ignores objects
- that are packed and/or not in the local object store
- (i.e. borrowed from an alternate).
+ This flag causes an object that is borrowed from an alternate
+ object store to be ignored even if it would have otherwise been
+ packed.
--non-empty::
Only create a packed archive if it would contain at
wholesale enforcement of a different compression level on the
packed data is desired.
---compression=[N]::
+--compression=<n>::
Specifies compression level for newly-compressed data in the
generated pack. If not specified, pack compression level is
determined first by pack.compression, then by core.compression,
Add --no-reuse-object if you want to force a uniform compression
level on all data no matter the source.
+--thin::
+ Create a "thin" pack by omitting the common objects between a
+ sender and a receiver in order to reduce network transfer. This
+ option only makes sense in conjunction with --stdout.
++
+Note: A thin pack violates the packed archive format by omitting
+required objects and is thus unusable by git without making it
+self-contained. Use `git index-pack --fix-thin`
+(see linkgit:git-index-pack[1]) to restore the self-contained property.
+
--delta-base-offset::
A packed archive can express base object of a delta as
either 20-byte object name or as an offset in the
