 --partial option tells rsync to keep the partial file which should
 make a subsequent transfer of the rest of the file much faster.
 
+dit(bf(--partial-dir=DIR)) Turns on --partial mode, but tells rsync to
+put a partially transferred file into DIR instead of writing out the
+file to the destination dir.  Rsync will also use a file found in this
+dir as data to speed up a subsequent transfer.
+
+Rsync will create the dir if it is missing, so feel free to use a
+relative path (such as quote(--partial-dir=.rsync-partial)) if you
+want the file put into a directory relative to the current directory
+in the tree (rsync will also try to remove the DIR if a partial file
+was found and the DIR was specified as a relative path).
+
+If you want to delete files on the destination, be sure to use
+--delete-after instead of --delete or the partial file may be deleted
+before it can be used.
+
 dit(bf(--progress)) This option tells rsync to print information
 showing the progress of the transfer. This gives a bored user
 something to watch.
