(synopsis "SCSI device utilities")
(description
"sg3-utils is a collection of utilities for devices that use the Small
Computer System Interface (@dfn{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:
@itemize
@item copy data based on @code{dd} syntax and semantics (called @command{sg_dd},
@command{sgp_dd}, and @command{sgm_dd})
@item check @code{INQUIRY} data and @code{VPD pages} (@command{sg_inq})
@item check mode and log pages (@command{sginfo}, @command{sg_modes}, and
@command{sg_logs})
@item spin up and down disks (@command{sg_start})
@item do self-tests (@code{sg_senddiag})
@item parse sense data (@code{sg_decode_sense})
@item and perform various other functions.
@end itemize
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!
