+ * interface must be implemented for each platform that uses the \ref
+ * timer "timer library".
+ *
+ * The clock interface does only one this: it measures time. The clock
+ * interface provides a macro, CLOCK_SECOND, which corresponds to one

+/**
+ * \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().
