     NAME
          spray - spray packets

     SYNOPSIS
          /usr/etc/spray host [-l length] [-c count]

     DESCRIPTION
          spray sends a one-way stream of packets to host using RPC,
          and then reports how many were received by host and what the
          transfer rate was.  The default value of length is 86 bytes
          (the size of the RPC and UDP headers) and the default value
          of count is the number of packets required to make the total
          stream size 100,000 bytes.  The host name can be either a
          name or an Internet address.

          The length parameter is the number of bytes in the Ethernet
          packet that holds the RPC call message.  Since the data is
          encoded using XDR and XDR only deals with 32 bit quantities,
          not all values of length are possible.  spray will round up
          to the nearest possible value.  When length is greater than
          1514, then the RPC call can no longer be encapsulated in one
          Ethernet packet, so the length field no longer has a simple
          correspondence to Ethernet packet size.
