+NVME Support
+============
+Firstly the author has no intention of extending this package to contain
+general purpose NVMe utilities. That leaves the areas where SCSI overlaps
+with NVMe. There was a SCSI to NVMe Translation Layer (SNTL) driver in the
+Linux kernel based on a white paper from NVM Express. Intel has withdrawn
+that driver and T10 (SCSI) and NVM Express have made no further attempts
+to standardize a SNTL. Given the SCSI to ATA Translation Layer (SATL) which
+is standardized by T10, it is pretty clear what a SNTL should do.
+
+The NVMe Management Interface (NVME-MI) committee have decided to use SES-3
+standard from T10 via the newly added SES Send and SES Receive MI commands.
+So the sg_ses utility and this package's library have been extended to use
+these commands when a NVMe device (typically a disk enclosure) is detected.
+This has been tested by a disk vendor who is happy with the results. Other
+user reports are welcome as the author does not have equipment to test
+this.
+
+Other utilities in this package that use the SES Send and Receive commands,
+or the SNTL in the library are sg_senddiag, sg_inq and sg_readcap.

+        Hex data for various sg3_utils utilities
+        ========================================
+
+The files in this folder contain hexadecimal data (in ASCII) and associated
+comments (prefixed with the hash mark symbol ('#')).
+
+The utility that each hex file is associated with can be determined by
+prepending "sg_" to these filenames then going to the 'src' folder (a
+sibling folder to this one) and look for a match or partial match on
+the name.
+
+For example:
+    vpd_dev_id.hex
+after prepending 'sg_' becomes:
+    sg_vpd_dev_id.hex
+which is a partial match on the sg_vpd utility.
+The remaining 'dev_id.hex' is meant to suggest the 'device identifier'
+VPD page which is a mandatory VPD page.
+
+Assuming sg3_utils is installed, it can be tested like this:
+    sg_vpd --inhex=<folder_holding_sg3_utils>/inhex/vpd_dev_id.hex
+
+And should output this:
+
+Device Identification VPD page:
+  Addressed logical unit:
+    designator type: NAA,  code set: Binary
+      0x5000c5003011cb2b

+      SCSI name string:
+      naa.5000C5003011CB28
+
+
+Users are encouraged to send the author any ASCII hex files for utilities
+that support --inhex and don't have hex data already. Special cases are
+also welcome. They help the author test this code.
