+.Sh SYNOPSIS
+.Nm
+.Op Ar interface
+.Ar lladdr
+.Op Ar lladdr ...
+.Sh DESCRIPTION
+The
+.Nm
+program is used to send Wake on LAN (WoL) frames over a local
+Ethernet network to one or more hosts using their link layer (hardware)
+addresses.
+WoL functionality is generally enabled in a machine's BIOS
+and can be used to power on machines from a remote system without
+having physical access to them.
+.Pp
+.Ar interface
+is an Ethernet interface of the local machine and is used to send the
+Wake on LAN frames over it.
+If there is only one Ethernet device available that is up and running, then the
+.Ar interface
+argument can be omitted.
+.Ar lladdr
+is the link layer address of the remote machine.
+This can be specified as the actual hardware address
+(six hexadecimal numbers separated by colons)
+or as a hostname entry in
+.Pa /etc/ethers .
+.Nm
+accepts multiple
+.Ar lladdr
+addresses.
+Link layer addresses can be determined and set using
+.Xr ifconfig 8 .
