Collection of tools for SCSI devices that use the Linux SCSI
generic (sg) interface. Includes utilities to copy data based on
"dd" syntax and semantics (called sg_dd, sgp_dd and sgm_dd); check
INQUIRY data and associated pages (sg_inq); check mode and log
pages (sg_modes and sg_logs); spin up and down disks (sg_start);
do self tests (sg_senddiag); and various other functions. See the
README and CHANGELOG files. Requires the lk 2.4 series or better.
[In the lk 2.5 development series many of these utilities can be
used on the primary block device name (e.g. /dev/sda).]

Warning: Some of these tools access the internals of your system
and the incorrect usage of them may render your system inoperable.
