I missed another sloppy conversion of tuples into hex encoded strings
while making this script run with Python 3.
Fix odd line break in DESCR while here.
Feedback OK jca
mdprint prints the contents of the provided binary sun4v MD file.
If no file is provided, the "guest MD" is read from the device file "/dev/mdesc"
which is expected to be present on all sun4v guest domains.
If no file is provided and the -P/--PRI option is used, the PRI
(physical resource inventory) MD is read from the device file
"/devices/pseudo/ds_pri@0:ds_pri" (Solaris only).
The complete PRI is only available on the "primary" domain.
