'git-unpack-objects' command can read the packed archive and
expand the objects contained in the pack into "one-file
one-object" format; this is typically done by the smart-pull
commands when a pack is created on-the-fly for efficient network
transport by their peers.

In a packed archive, an object is either stored as a compressed
whole, or as a difference from some other object. The latter is
often called a delta.

+--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, which is the
+ default.
+
+--max-pack-size=<n>::
+ Maximum size of each output packfile, expressed in MiB.
+ If specified, multiple packfiles may be created.
+ The default is unlimited.

--incremental::
This flag causes an object already in a pack ignored
even if it appears in the standard input.

+--no-reuse-object::
+ This flag tells the command not to reuse existing object data at all,
+ including non deltified object, forcing recompression of everything.
+ This implies --no-reuse-delta. Useful only in the obscure case where
+ wholesale enforcement of a different compression level on the
+ packed data is desired.
+
+--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,
+ and defaults to -1, the zlib default, if neither is set.
+ Add \--no-reuse-object if you want to force a uniform compression
+ level on all data no matter the source.

+--threads=<n>::
+ Specifies the number of threads to spawn when searching for best

+ This is meant to reduce packing time on multiprocessor machines.
+ The required amount of memory for the delta search window is
