freebsd-dev/sbin/gpt/show.c
Marcel Moolenaar 5d5e1c2b12 o Add functionality to add a GPT partition,
o  Use DCE compliant UUID functions and provide local
   implementations if they don't exist,
o  Move dumping of the map to show.c and print the
   partition type,
o  Some cleanups and rearrangements.

The default GPT partition type is UFS. When no starting block
or size are specified, the tool will create a partition in the
first free space it find (or that fits, depending on the size).
