+ * @anchor modules_anchor
+ *
+ * @defgroup simulator Simulator
+ * The "simulator" module contains: 
+ *    - a time management class to hold a time and convert between various time units: ns3::Time 
+ *    - a scheduler base class used to implement new simulation event schedulers:       
+ *      ns3::Scheduler and ns3::SchedulerFactory 
+ *    - a simulator class used to create, schedule and cancel events: ns3::Simulator
+ *
+ * @defgroup core Core
+ * \brief The "core" module contains:
+ *    - a Functor class: ns3::Callback  
+ *    - an os-independent interface to get access to the elapsed wall clock time: ns3::SystemWallClockMs 
+ *    - a class to register regression tests with the test manager: ns3::Test and ns3::TestManager
+ *    - debugging facilities: \ref logging, \ref assert, \ref error
+ *    - \ref randomvariable
+ *    - \ref config
+ *    - a base class for objects which need to support reference counting
+ *      and QueryInterface: ns3::Object and ns3::InterfaceId 
+ *    - a set of low-level trace facilities integrated in the ns3::Object system: \ref tracing
+ *    - a ns3::ComponentManager which can be used to manage the creation
+ *      of any object which derives from ns3::Object through an ns3::ClassId 
+ *    - a smart-pointer class ns3::Ptr designed to work together with ns3::Object
+ *
+ * @defgroup common Common
+ * The "core" module contains: 
+ *    - a packet class to create and manipulate simulation packets: 
+ *      ns3::Packet, ns3::Header,  and ns3::Trailer. This packet class 
+ *      also supports per-packet ns3::Tag which are  globs of data 
+ *      which can be attached to any packet.
+ *
+ * @defgroup node Node
+ * The "node" module contains:
+ *    - a ns3::Node base class which should be subclassed by any new type of
+ *      network Node.
+ *    - models which abstract the MAC-layer from the IP layer protocols:
+ *      ns3::NetDevice and ns3::Channel. 
+ *    - models which abstract the application-layer API: ns3::Application,
+ *      ns3::Socket, ns3::SocketFactory, and, ns3::Udp
+ * 
+ *
+ * @defgroup devices Devices
+ * The "devices" module contains:
+ *    - a PointToPoint MAC device: ns3::PointToPointNetDevice, ns3::PointToPointChannel,
+ *      and ns3::PointToPointTopology.
+ *
+ * @defgroup internetNode InternetNode
+ * 
+ * The "internet-node" module contains a set of classes which implement the
+ * APIs defined in the "node" module:
+ *    - an Ipv4/Udp stack with socket support 
+ *    - an ARP module
+ *    - an InternetNode class which is a Node subclass.
+ *    
+ * @defgroup applications Applications

+ * @defgroup mobility Mobility
+ *
+ * @defgroup routing Routing
+ *
+ * @defgroup constants Constants
+ * @brief Constants you can change
