+.TP
+.BR \-U\ \fIUUID
+Create a cache device with the specified UUID
+.TP
+.BR \-b\ \fIbucket-size
+Spcifies the bucket size. Allocation is done in terms of buckets, and cache
+hits are counted per bucket; thus a smaller bucket size will give better cache
+utilization, but poorer write performance. The bucket size is intended to be
+equal to the size of your SSD's erase blocks, which seems to be 128k-512k for
+most SSDs. Must be a power of two; accepts human readable units. Defaults to
+128k.
