+/*! \page qtsinglecoreapplication-example-console.html
+    \title A non-GUI example
+
+    This example shows how to use the single-application functionality
+    in a console application. It does not require the \c QtGui library
+    at all.
+
+    The only differences from the GUI application usage demonstrated
+    in the other examples are:
+
+    1) The \c.pro file should include \c qtsinglecoreapplication.pri
+       instead of \c qtsingleapplication.pri
+
+    2) The class name is \c QtSingleCoreApplication instead of \c
+       QtSingleApplication.
+
+    3) No calls are made regarding window activation, for obvious reasons.

+    \title A Trivial Example
+
+    The application in this example has a log-view that displays
+    messages sent by further instances of the same application.
+
+    The example demonstrates the use of the QtSingleApplication
+    class to detect and communicate with a running instance of
+    the application using the sendMessage() API. The messageReceived()
+    signal is used to display received messages in a QTextEdit log.
+
+    \quotefromfile trivial/main.cpp
+    \printuntil instance
+    The example has only the \c main entry point function.
+    A QtSingleApplication object is created immediately.
+
+    \printuntil return 
+    If another instance of this application is already running,
+    sendMessage() will succeed, and this instance just exits
+    immediately.
+
+    \printuntil show()
+    Otherwise the instance continues as normal and creates the
+    user interface.
+
+    \printuntil return instance.exec();
+    The \c logview object is also set as the application's activation
+    window. Every time a message is received, the window will be raised
+    and activated automatically.
+
+    The messageReceived() signal is also connected to the QTextEdit's
+    append() slot. Every message received from further instances of
+    this application will be displayed in the log.
+
+    Finally the event loop is entered.
