+// service.h - declaring services and definitions
+//
+// Synopsis
+//
+// Example 1: A protocol might be declared as a class as follows
+//
+//    Collection col;                            // collection used during setup
+//
+//    Characteristic<ObjectId>   id(col,0x2AC3,"rw","ID");
+//    Characteristic<ObjectName> name(col,0x2ABE,"rw","Name");
+//    Characteristic<Digital>    presence(col,0x2A56,"r","Presence");
+//
+//    Service presenceDetection(col,0xA001);     // instantiate service
+//
+//    onSetup(Blob &blue)
+//    {
+//       blue.service(presenceDetection);        // use service    
+//    }
+//
+// Example 2: service definition by means of a service definition class
+//
+//   class PresenceDetector
+//   {
+//      public:
+//         Collection col;                       // collection used during setup 
+//
+//         Characteristic<ObjectId> id;          // ID of presence detector
+//         Characteristic<ObjectName> name;      // name of presence detector
+//         Characteristic<Digital> presence;     // digital presence value
+//         Characteristic<DateTime> timestamp;   // last detection change's time
+//         Characteristic<ObjectName> layout;    // name of model railway layout
+//
+//         Service presenceDetection;            // the service
+//
+//      public:
+//         PresenceDetector(Blob &blue, cost UUID uuid) :
+//            list;                              // init service list
+//            id(list,0x2AC3,"rw","ID"),         // instantiate characteristic
+//            name(list,0x2ABE,"rw","Name"),     // instantiate characteristic
+//            presence(list,0x2A56,"r","Presence"),// instantiate characteristic
+//            timestamp(list,0x2A08,"r","Timestamp"),// instantiate characteristic
+//            layout(list,0x2ABE,"rw","Layout"), // instantiate characteristic
+//            presenceDetection(list,uuid)       // instantiate service
+//         {
+//            Blob blue;    
+//            blue.service(presenceDetection);   // use service    
+//         }
+//   };
