+dit(bf(--max-size=SIZE)) This tells rsync to avoid transferring any
+file that is larger than the specified SIZE. The SIZE value can be
+suffixed with a letter to indicate a size multiplier (K, M, or G) and

 dit(bf(--delete)) This tells rsync to delete any files on the receiving
 side that aren't on the sending side.   Files that are excluded from
 transfer are excluded from being deleted unless you use --delete-excluded.
