+from a range of nfs-utils configuration files.

+.IP "\fB\-i, \-\-isset\fP"
+Test if a specific tag has a value set.
+.IP "\fB\-g, \-\-get\fP"
+Output the current value of the specified tag.
+.SH OPTIONS

+.TP
+.B \-f, \-\-file \fIinfile\fR

+In this mode the command will return success (0) if the selected tag has a value, any other exit code indicates the value is not set, or some other error has occured.
+.SS all other modes
+Success is indicated by an exit status of zero, any other status indicates an error. Error messages are output on stderr, and increasing verbosity will give more detailed explanations if any are available.
