+--fix-thin::
+       It is possible for gitlink:git-pack-objects[1] to build
+       "thin" pack, which records objects in deltified form based on
+       objects not included in the pack to reduce network traffic.
+       Those objects are expected to be present on the receiving end
+       and they must be included in the pack for that pack to be self
+       contained and indexable. Without this option any attempt to
+       index a thin pack will fail. This option only makes sense in
+       conjonction with --stdin.
