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