+/*! \page qtsingleapplication-example-loader.html
+    \title Loading Documents
+
+    The application in this example loads or prints the documents 
+    passed as commandline parameters to further instances of this
+    application.
+
+    \quotefromfile loader/main.cpp
+    \printuntil };
+    The user interface in this application is a QMainWindow subclass
+    with a QMdiArea as the central widget. It implements a slot
+    \c handleMessage() that will be connected to the messageReceived()
+    signal of the QtSingleApplication class.
+
+    \printuntil }
+    The MainWindow constructor creates a minimal user interface.
+
+    \printto case Print:
+    The handleMessage() slot interprets the message passed in as a
+    filename that can be prepended with \e /print to indicate that
+    the file should just be printed rather than loaded.
+
+    \printto #include
+    Loading the file will also activate the window.
+
+    \printto mw
+    The \c main entry point function creates a QtSingleApplication
+    object, and creates a message to send to a running instance
+    of the application. If the message was sent successfully the
+    process exits immediately.
+
+    \printuntil }
+    If the message could not be sent the application starts up.  Note
+    that \c false is passed to the call to setActivationWindow() to
+    prevent automatic activation for every message received, e.g. when
+    the application should just print a file. Instead, the message
+    handling function determines whether activation is requested, and
+    signals that by emitting the needToShow() signal. This is then
+    simply connected directly to QtSingleApplication's
+    activateWindow() slot.
