+ * \brief Socket handling
+ *
+ * The model of communications in GRAS is very close to the BSD socket one.
+ * To get two hosts exchanging data, one of them need to open a
+ * <i>server</i> socket on which it can listen for incoming messages and the
+ * other one must connect a <i>client</i> socket onto the server one.
+ *
+ * The main difference is that you cannot exchange arbitrary bytes on
+ * sockets, but messages. See the \ref GRAS_msg section for details.
+ *
+ * If you need an example of how to use sockets, check \ref GRAS_ex_ping.
