define Package/duperemove/description
  Duperemove is a simple tool for finding duplicated extents and submitting
  them for deduplication. When given a list of files it will hash their
  contents on an extent by extent basis and compare those hashes to each
  other, finding and categorizing extents that match each other. Optionally,
  a per-block hash can be applied for further duplication lookup. When given
  the -d option, duperemove will submit those extents for deduplication using
  the Linux kernel FIDEDUPRANGE ioctl.
