-git-repack - Script used to pack a repository from a collection of

+git-repack - Pack unpacked objects in a repository
SYNOPSIS
-----------
This script is used to combine all objects that do not currently
-reside in a "pack", into a pack.
+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

+ 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.
+
+--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.
