     choparp is a easy-to-use proxy arp daemon.  It watches arp request pack-
     ets visible on the interface specified by argument if_name, and sends
     proxy arp reply to the sender if the arp request queries the MAC address
     (ethernet hardware address) for the network speicified by net_addr and
     net_mask.
