-Generate a deduplicated stream.  Blocks which would have been sent multiple
-times in the send stream will only be sent once.  The receiving system must
-also support this feature to recieve a deduplicated stream.  This flag can
-be used regardless of the dataset's \fBdedup\fR property, but performance
-will be much better if the filesystem uses a dedup-capable checksum (eg.
-\fBsha256\fR).
