marping (Multi-ARp-PING) is a (tiny) command line utility for *nix operating 
systems used to discover systems in local network and gather their 
MAC addresses. 
Discovery is performed by sending ARP (address resolution 
protocol) requests ("who-has <ip> tell..") and listening to coming 
answers. However, unlike similar utilities, it's destined to perform 
rather massive scans very fast.
Output to stdout is in "MAC<space>IP" format (by default not found addresses aren't listed).

Examples:
	marping 192.168.0.1 192.168.1.1
	tries to get MAC addresses of 192.168.0.1 and 192.168.1.1, uses default interface/timeout options (0.6sec)

	marping -t 10000 -i br0 -f /etc/hosts
	reads file /etc/hosts taking IPv4 addresses, then scans for their MACs using br0 interface and timeout of 1 second
