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

+/*\r
+ * uIP is a small implementation of the IP, UDP and TCP protocols (as\r
+ * well as some basic ICMP stuff). The implementation couples the IP,\r
+ * UDP, TCP and the application layers very tightly. To keep the size\r
+ * of the compiled code down, this code frequently uses the goto\r
+ * statement. While it would be possible to break the uip_process()\r
+ * function into many smaller functions, this would increase the code\r
+ * size because of the overhead of parameter passing and the fact that\r
+ * the optimier would not be as efficient.\r
+ *\r
+ * The principle is that we have a small buffer, called the uip_buf,\r
+ * in which the device driver puts an incoming packet. The TCP/IP\r
+ * stack parses the headers in the packet, and calls the\r
+ * application. If the remote host has sent data to the application,\r
+ * this data is present in the uip_buf and the application read the\r
+ * data from there. It is up to the application to put this data into\r
+ * a byte stream if needed. The application will not be fed with data\r
+ * that is out of sequence.\r
+ *\r
+ * If the application whishes to send data to the peer, it should put\r
+ * its data into the uip_buf. The uip_appdata pointer points to the\r
+ * first available byte. The TCP/IP stack will calculate the\r
+ * checksums, and fill in the necessary header fields and finally send\r
+ * the packet back to the peer.\r
