+       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 both --window and --depth is 10.
