+ * 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.
+ * 
+ * If you need an example of this, check \ref GRAS_ex_ping.

  * For debugging purpose, it is possible to deal with files as if they were sockets.
  * It can even be useful to store stuff in a portable manner, but writing messages to a file
