  41     (description
  42      "sg3-utils is a collection of utilities for devices that use the Small
  43 Computer System Interface (@dfn{SCSI}) command set.  It includes utilities to
  44 read data from, write data to, control, modify, and query the state of SCSI
  45 devices.
  46
  47 For example, this package provides command-line tools to:
  48 @itemize
  49 @item copy data based on @code{dd} syntax and semantics (called @command{sg_dd},
  50 @command{sgp_dd}, and @command{sgm_dd})
  51 @item check @code{INQUIRY} data and @code{VPD pages} (@command{sg_inq})
  52 @item check mode and log pages (@command{sginfo}, @command{sg_modes}, and
  53 @command{sg_logs})
  54 @item spin up and down disks (@command{sg_start})
  55 @item do self-tests (@code{sg_senddiag})
  56 @item parse sense data (@code{sg_decode_sense})
  57 @item and perform various other functions.
  58 @end itemize
  59
  60 In addition, this package includes a library, called libsgutils, which can be
  61 used in C and C++ programs to interact with SCSI devices.")
  62     ;; See README: "All utilities and libraries have either a "2 clause" BSD
  63     ;;   license or are "GPL-2ed". [...] That BSD license was updated from the
  64     ;;   "3 clause" to the newer "2 clause" version on 20180119. To save space
  65     ;;   various source code files refer to a file called "BSD_LICENSE" [...]."
  66     ;; Some files (like sg_compare_and_write.c) retain their 3-clause headers!
