21--object-dir=<dir>::
22 Use given directory for the location of Git objects. We check
23 `<dir>/packs/multi-pack-index` for the current MIDX file, and
24 `<dir>/packs` for the pack-files to index.

38expire::
39 Delete the pack-files that are tracked by the MIDX file, but
40 have no objects referenced by the MIDX. Rewrite the MIDX file
41 afterward to remove all references to these pack-files.

43repack::
44 Create a new pack-file containing objects in small pack-files
45 referenced by the multi-pack-index. If the size given by the
46 `--batch-size=<size>` argument is zero, then create a pack
47 containing all objects referenced by the multi-pack-index. For
48 a non-zero batch size, Select the pack-files by examining packs
49 from oldest-to-newest, computing the "expected size" by counting
50 the number of objects in the pack referenced by the
51 multi-pack-index, then divide by the total number of objects in
52 the pack and multiply by the pack size. We select packs with
53 expected size below the batch size until the set of packs have

DS
54 total expected size at least the batch size, or all pack-files
55 are considered. If only one pack-file is selected, then do
56 nothing. If a new pack-file is created, rewrite the
57 multi-pack-index to reference the new pack-file. A later run of
58 'git multi-pack-index expire' will delete the pack-files that
59 were part of this batch.

61If `repack.packKeptObjects` is `false`, then any pack-files with an
62associated `.keep` file will not be selected for the batch to repack.
