/**
 * \mainpage SuperTuxKart developer documentation
 *
 * This document contains the developer documentation for SuperTuxKart,
 * including the list of modules, the list of classes, the API reference,
 * and some pages that describe in more depth some parts of the code/engine.
 *
 * \section Overview
 *
 * Here is an overview of the high-level interactions between modules :
 \dot
 digraph interaction {
 race -> modes
 race -> tracks
 race -> karts
 modes -> tracks
 modes -> karts
 tracks -> graphics
 karts -> graphics
 tracks -> items
 graphics -> irrlicht
 guiengine -> irrlicht
 states_screens -> guiengine
 states_screens -> input
 guiengine -> input
 karts->physics
 tracks->physics
 karts -> controller
 input->controller
 tracks -> animations
 physics -> animations
 }
 \enddot

 Note that this graph is only an approximation because the real one would be
 much too complicated :)


 \section Modules

 \li \ref addonsgroup :
   Handles add-ons that can be downloaded.
 \li \ref animations :
   This module manages interpolation-based animation (of position, rotation
   and/or scale)
 \li \ref audio :
   This module handles audio (sound effects and music).
 \li \ref challenges :
   This module handles the challenge system, which locks features (tracks, karts
   modes, etc.) until the user completes some task.
 \li \ref config :
   This module handles the user configuration, the supertuxkart configuration
   file (which contains options usually not edited by the player) and the input
   configuration file.
 \li \ref graphics :
   This module contains the core graphics engine, that is mostly a thin layer
   on top of irrlicht providing some additional features we need for STK
   (like particles, more scene node types, mesh manipulation tools, material
   management, etc...)
 \li \ref guiengine :
   Contains the generic GUI engine (contains the widgets and the backing logic
   for event handling, the skin, screens and dialogs). See module @ref states_screens
   for the actual STK GUI screens. Note that all input comes through this module
   too.
 \li \ref widgetsgroup :
   Contains the various types of widgets supported by the GUI engine.
 \li \ref input :
   Contains classes for input management (keyboard and gamepad)
 \li \ref io :
  Contains generic utility classes for file I/O (especially XML handling).
 \li \ref items :
   Defines the various collectibles and weapons of STK.
 \li \ref karts :
   Contains classes that deal with the properties, models and physics
   of karts.
 \li \ref controller :
   Contains kart controllers, which are either human players or AIs
   (this module thus contains the AIs)
 \li \ref modes :
   Contains the logic for the various game modes (race, follow the leader,
   battle, etc.)
 \li \ref physics :
   Contains various physics utilities.
 \li \ref race :
   Contains the race information that is conceptually above what you can find
   in group Modes. Handles highscores, grands prix, number of karts, which
   track was selected, etc.
 \li \ref states_screens :
   Contains the various screens and dialogs of the STK user interface,
   using the facilities of the guiengine module. Also contains the
   stack of menus and handles state management (in-game vs menu).
 \li \ref tracks :
   Contains information about tracks, namely drivelines, checklines and track
   objects.
 \li \ref tutorial :
   Work in progress
