+repack::
+ Create a new pack-file containing objects in small pack-files
+ referenced by the multi-pack-index. If the size given by the
+ `--batch-size=<size>` argument is zero, then create a pack
+ containing all objects referenced by the multi-pack-index. For
+ a non-zero batch size, Select the pack-files by examining packs
+ from oldest-to-newest, computing the "expected size" by counting
+ the number of objects in the pack referenced by the
+ multi-pack-index, then divide by the total number of objects in
+ the pack and multiply by the pack size. We select packs with
+ expected size below the batch size until the set of packs have
+ total expected size at least the batch size. If the total size
+ does not reach the batch size, then do nothing. If a new pack-
+ file is created, rewrite the multi-pack-index to reference the
+ new pack-file. A later run of 'git multi-pack-index expire' will
+ delete the pack-files that were part of this batch.
