-    \example statemachine/tankgame
-    \title Tank Game Example
-
-    The Tank Game example is part of the in \l{The State Machine Framework}. It shows how to use 
-    parallel states to implement artificial intelligence controllers that run in parallel, and error 
-    states to handle run-time errors in parts of the state graph created by external plugins.
-
-    \image tankgame-example.png
-
-    In this example we write a simple game. The application runs a state machine with two main 
-    states: A "stopped" state and a "running" state. The user can load plugins from the disk by 
-    selecting the "Add tank" menu item. 
-    
-    When the "Add tank" menu item is selected, the "plugins" subdirectory in the example's 
-    directory is searched for compatible plugins. If any are found, they will be listed in a 
-    dialog box created using QInputDialog::getItem().
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 1
-    
-    If the user selects a plugin, the application will construct a TankItem object, which inherits
-    from QGraphicsItem and QObject, and which implements an agreed-upon interface using the 
-    meta-object mechanism.
-    
-    \snippet examples/statemachine/tankgame/tankitem.h 0
-    
-    The tank item will be passed to the plugin's create() function. This will in turn return a 
-    QState object which is expected to implement an artificial intelligence which controls the 
-    tank and attempts to destroy other tanks it detects.
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 2
-    
-    Each returned QState object becomes a descendant of a \c region in the "running" state, which is 
-    defined as a parallel state. This means that entering the "running" state will cause each of the 
-    plugged-in QState objects to be entered simultaneously, allowing the tanks to run independently
-    of each other.
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 0
-    
-    The maximum number of tanks on the map is four, and when this number is reached, the 
-    "Add tank" menu item should be disabled. This is implemented by giving the "stopped" state two
-    children which define whether the map is full or not. 
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 5
-    
-    To make sure that we go into the correct child state when returning from the "running" state 
-    (if the "Stop game" menu item is selected while the game is running) we also give the "stopped" 
-    state a history state which we make the initial state of "stopped" state.
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 3
-    
-    Since part of the state graph is defined by external plugins, we have no way of controlling
-    whether they contain errors. By default, run-time errors are handled in the state machine by
-    entering a top level state which prints out an error message and never exits. If we were to 
-    use this default behavior, a run-time error in any of the plugins would cause the "running"
-    state to exit, and thus all the other tanks to stop running as well. A better solution would
-    be if the broken plugin was disabled and the rest of the tanks allowed to continue as before.
-    
-    This is done by setting the error state of the plugin's top-most state to a special error state
-    defined specifically for the plugin in question.
-    
-    \snippet examples/statemachine/tankgame/mainwindow.cpp 4
-    
-    If a run-time error occurs in \c pluginState or any of its descendants, the state machine will
-    search the hierarchy of ancestors until it finds a state whose error state is different from
-    \c null. (Note that if we are worried that a plugin could inadvertedly be overriding our 
-    error state, we could search the descendants of \c pluginState and verify that their error 
-    states are set to \c null before accepting the plugin.)
-    
-    The specialized \c errorState sets the "enabled" property of the tank item in question to false, 
-    causing it to be painted with a red cross over it to indicate that it is no longer running. 
-    Since the error state is a child of the same region in the parallel "running" state as 
-    \c pluginState, it will not exit the "running" state, and the other tanks will continue running
-    without disruption.
