and
+submitting them for deduplication. When given a list of files it will hash 
their
+contents on a block by block basis and compare those hashes to each other,
+finding and categorizing blocks that match each other. When given the -d 
option,
+duperemove will submit those extents for deduplication using the Linux kernel
+extent-same ioctl.
+
+Duperemove can store the hashes it computes in a 'hashfile'. If given an
+existing hashfile, duperemove will only compute hashes for those files which
+have changed since the last run. Thus you can run duperemove repeatedly on your
+data as it changes, without having to re-checksum unchanged data.
+
+Duperemove can also take input from the fdupes program.")
