+.Sh SYNOPSIS
+.Nm spray
+.Op Fl c Ar count
+.Op Fl d Ar delay
+.Op Fl l Ar length
+.Ar host
+\&...
+.Ek
+.Sh DESCRIPTION
+.Nm Spray
+sends multiple RPC packets to
+.Ar host
+and records how many of them were correctly received and how long it took.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl c Ar count
+Send
+.Ar count
+packets.
+.It Fl d Ar delay
+Pause
+.Ar delay
+microseconds between sending each packet.
+.It Fl l Ar length
+Set the length of the packet that holds the RPC call message to
+.Ar length
+bytes.
+Not all values of
+.Ar length
+are possible because RPC data is encoded using XDR.
+.Nm Spray
+rounds up to the nearest possible value.
+.El
+.Pp
+.Nm Spray
+is intended for use in network testing, measurement, and management.
+This command
+.Bf -emphasis
+can be very hard on a network and should be used with caution.
