 The chunker option, '-s', specifies the chunking strategy that dictates
 how to break files into blocks. Blocks with same content can
-be deduplicated. The default is a fixed block size of
+be deduplicated. Different chunking strategies will produce different
+hashes for the same file. The default is a fixed block size of
 256 * 1024 bytes, 'size-262144'. Alternatively, you can use the
-rabin chunker for content defined chunking by specifying
-rabin-[min]-[avg]-[max] (where min/avg/max refer to the resulting
-chunk sizes). Using other chunking strategies will produce
-different hashes for the same file.
