See the --acls (-A) option in the revised man page for a note on using this
latest ACL-enabling patch to send files to an older ACL-enabled rsync.
-This code does not yet itemize changes in ACL information (see --itemize).
+TODO items:
+
+- The -i option does not yet itemize changes in ACL information.
+
+- The --link-dest option might link together two files that differ just
+ in their ACL info, and if that happens the file in the --link-dest dir
+ would get its ACLs updated.
