+
+    A file may be locked in read or write mode. Multiple instances of
+    \e QtLockedFile, created in multiple processes running on the same
+    machine, may have a file locked in read mode. Exactly one instance
+    may have it locked in write mode. A read and a write lock cannot
+    exist simultaneously on the same file.
+
+    The file locks are advisory. This means that nothing prevents
+    another process from manipulating a locked file using QFile or
+    file system functions offered by the OS. Serialization is only
+    guaranteed if all processes that access the file use
+    QLockedFile. Also, while holding a lock on a file, a process
+    must not open the same file again (through any API), or locks
+    can be unexpectedly lost.
+
+    The lock provided by an instance of \e QtLockedFile is released
+    whenever the program terminates. This is true even when the
+    program crashes and no destructors are called.

+/*!
+    \class QtSingleApplication qtsingleapplication.h
+    \brief The QtSingleApplication class provides an API to detect and
+    communicate with running instances of an application.
+
+    This class allows you to create applications where only one
+    instance should be running at a time. I.e., if the user tries to
+    launch another instance, the already running instance will be
+    activated instead. Another usecase is a client-server system,
+    where the first started instance will assume the role of server,
+    and the later instances will act as clients of that server.
+
+    By default, the full path of the executable file is used to
+    determine whether two processes are instances of the same
+    application. You can also provide an explicit identifier string
+    that will be compared instead.
+
+    The application should create the QtSingleApplication object early
+    in the startup phase, and call isRunning() to find out if another
+    instance of this application is already running. If isRunning()
+    returns false, it means that no other instance is running, and
+    this instance has assumed the role as the running instance. In
+    this case, the application should continue with the initialization
+    of the application user interface before entering the event loop
+    with exec(), as normal.
+
+    The messageReceived() signal will be emitted when the running
+    application receives messages from another instance of the same
+    application. When a message is received it might be helpful to the
+    user to raise the application so that it becomes visible. To
+    facilitate this, QtSingleApplication provides the
+    setActivationWindow() function and the activateWindow() slot.
+
+    If isRunning() returns true, another instance is already
+    running. It may be alerted to the fact that another instance has
+    started by using the sendMessage() function. Also data such as
+    startup parameters (e.g. the name of the file the user wanted this
+    new instance to open) can be passed to the running instance with
+    this function. Then, the application should terminate (or enter
+    client mode).
+
+    If isRunning() returns true, but sendMessage() fails, that is an
+    indication that the running instance is frozen.
+
+    Here's an example that shows how to convert an existing
+    application to use QtSingleApplication. It is very simple and does
+    not make use of all QtSingleApplication's functionality (see the
+    examples for that).
+
+    \code
+    // Original
+    int main(int argc, char **argv)
+    {
+        QApplication app(argc, argv);
+
+        MyMainWidget mmw;
+        mmw.show();
+        return app.exec();
+    }
+
+    // Single instance
+    int main(int argc, char **argv)
+    {
+        QtSingleApplication app(argc, argv);
+
+        if (app.isRunning())
+            return !app.sendMessage(someDataString);
+
+        MyMainWidget mmw;
+        app.setActivationWindow(&mmw);
+        mmw.show();
+        return app.exec();
+    }
+    \endcode
+
+    Once this QtSingleApplication instance is destroyed (normally when
+    the process exits or crashes), when the user next attempts to run the
+    application this instance will not, of course, be encountered. The
+    next instance to call isRunning() or sendMessage() will assume the
+    role as the new running instance.
+
+    For console (non-GUI) applications, QtSingleCoreApplication may be
+    used instead of this class, to avoid the dependency on the QtGui
+    library.
