112 .\" ---------------------- BUGS ----------------------------------
114 The default output has be changed. To get the old default output you must run \fBnfsstat --auto -2\fR.
116 The function of the \fB-v\fR and \fB-a\fR options have changed. The \fB-a\fR option
117 is now reserved for future use. The \fB-v\fR does what the \fB-a\fR option used to do,
118 and the new \fB-[234]\fR options replace the \fB-v\fR option.
120 The \fBDisplay\fR section should be more complete.
