+WARNING
+-------
+`git pack-redundant` has been deprecated and is scheduled for removal in
+a future version of Git. Because it can only remove entire duplicate
+packs and not individual duplicate objects, it is generally not a useful
+tool for reducing repository size. You are better off using `git gc` to
+do so, which will put objects into a new pack, removing duplicates.
+
+Running `pack-redundant` without the `--i-still-use-this` flag will fail
+in this release. If you believe you have a use case for which
+`pack-redundant` is better suited and oppose this removal, please
+contact the Git mailing list at git@vger.kernel.org. More information
+about the list is available at https://git-scm.com/community.
+
 DESCRIPTION
 -----------
 This program computes which packs in your repository
