+section for details, and also the bf(--only-write-batch) option.
+
+dit(bf(--only-write-batch=FILE)) Works like bf(--write-batch), except that
+no updates are made on the destination system when creating the batch.
+This lets you transport the changes to the destination system via some
+other means and then apply the changes via bf(--read-batch).
+
+Note that you can feel free to write the batch directly to some portable
+media: if this media fills to capacity before the end of the transfer, you
+can just apply that partial transfer to the destination and repeat the
+whole process to get the rest of the changes (as long as you don't mind a
+partially updated destination system while the multi-update cycle is
+happening).
+
+Also note that you only save bandwidth when pushing changes to a remote
+system because this allows the batched data to be diverted from the sender
+into the batch file without having to flow over the wire to the receiver
+(when pulling, the sender is remote, and thus can't write the batch).
 
 dit(bf(--read-batch=FILE)) Apply all of the changes stored in FILE, a
 file previously generated by bf(--write-batch).
