WOL is based on the following principle: 

When the PC shuts down, the NIC still gets power, and keeps listening on the network for a 'magic' packet to arrive. This packet must contain a certain byte-sequence, but can be encapsulated in any kind of packet (IPX, IP, anything). Take a look at the code for the magic sequence. 

This program uses UDP for sending the packet. The complete UDP packet, sent over an ethernet interface, looks something like this: 

[ethernet header][IP header][UDP header][Magic sequence][CRCS] 

The only goal of the script is to send this packet over the network. It expects no returning data, since the NIC only listens, and does not reply anything. 

For a more detailed description of the protocol, see the AMD white paper.
