 are redundant. The output is suitable for piping to
 'xargs rm' if you are in the root of the repository.
 
+git-pack-redundant accepts a list of objects on standard input. Any objects
+given will be ignored when checking which packs are required. This makes the 
+following command useful when wanting to remove packs which contain unreachable
+objects.
