 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

-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

-updated destination system while the multi-update cycle is happening).
