-+This is a small implementation of the IP and TCP protocols (as well as
-+some basic ICMP stuff). The implementation couples the IP, TCP and the
-+application layers very tightly. To keep the size of the compiled code
-+down, this code also features heavy usage of the goto statement.
-+
-+The principle is that we have a small buffer, called the uip_buf, in
-+which the device driver puts an incoming packet. The TCP/IP stack
-+parses the headers in the packet, and calls upon the application. If
-+the remote host has sent data to the application, this data is present
-+in the uip_buf and the application read the data from there. It is up
-+to the application to put this data into a byte stream if needed. The
-+application will not be fed with data that is out of sequence.
-+
-+If the application whishes to send data to the peer, it should put its
-+data into the uip_buf, 40 bytes from the start of the buffer. The
-+TCP/IP stack will calculate the checksums, and fill in the necessary
-+header fields and finally send the packet back to the peer.
