+/**
+ * \defgroup psock Protosockets library
+ * @{
+ *
+ * The protosocket library provides an interface to the uIP stack that is
+ * similar to the traditional BSD socket interface. Unlike programs
+ * written for the ordinary uIP event-driven interface, programs
+ * written with the protosocket library are executed in a sequential
+ * fashion and does not have to be implemented as explicit state
+ * machines.
+ *
+ * Protosockets only work with TCP connections.
+ *
+ * The protosocket library uses \ref pt protothreads to provide
+ * sequential control flow. This makes the protosockets lightweight in
+ * terms of memory, but also means that protosockets inherits the
+ * functional limitations of protothreads. Each protosocket lives only
+ * within a single function. Automatic variables (stack variables) are
+ * not retained across a protosocket library function call.
+ *
+ * \note Because the protosocket library uses protothreads, local
+ * variables will not always be saved across a call to a protosocket
+ * library function. It is therefore advised that local variables are
+ * used with extreme care.
+ *
+ * The protosocket library provides functions for sending data without
+ * having to deal with retransmissions and acknowledgements, as well
+ * as functions for reading data without having to deal with data
+ * being split across more than one TCP segment.
+ *
+ * Because each protosocket runs as a protothread, the protosocket has to be
+ * started with a call to PSOCK_BEGIN() at the start of the function
+ * in which the protosocket is used. Similarly, the protosocket protothread can
+ * be terminated by a call to PSOCK_EXIT().

+ * uIP is a small implementation of the IP, UDP and TCP protocols (as
+ * well as some basic ICMP stuff). The implementation couples the IP,
+ * UDP, TCP and the application layers very tightly. To keep the size
+ * of the compiled code down, this code frequently uses the goto
+ * statement. While it would be possible to break the uip_process()
+ * function into many smaller functions, this would increase the code
+ * size because of the overhead of parameter passing and the fact that
+ * the optimier would not be as efficient.
+ *
+ * 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 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. The uip_appdata pointer points to the
+ * first available byte. The TCP/IP stack will calculate the
+ * checksums, and fill in the necessary header fields and finally send
+ * the packet back to the peer.
