BUGS
The default output has be changed. To get the old default output you must run nfsstat --auto -2.
The function of the -v and -a options have changed. The -a option
is now reserved for future use. The -v does what the -a option used to do,
and the new -[234] options replace the -v option.
The Display section should be more complete.
