+\title Application Features Example
+\image application-features.png
+\brief Showcases client applications with various features, including a native application.
+\ingroup applicationmanager-examples
+
+\section1 Introduction
+
+This example demonstrates some particular features that an application might implement, for
+instance it shows how to implement a nested compositor and it is the only example with an
+application that uses the "native" runtime. Most of the features are only supported properly in
+multi-process mode (for details see the following section).
+
+\note This example focuses on the application (client) side. The System UI (compositor/server) is just a
+modified version of the "Desktop System UI Example" (minidesk). For more information on how this
+System UI is implemented, see \l{Desktop System UI Example}.
+
+
+\section1 The Client Applications
+
+The following applications are included in this example:
+
+\section2 Nested Compositor
+The nested compositor application shows how a Wayland compositor can be implemented inside an
+application (Wayland client) window. The compositor is implemented in pure QML and is kept to a
+minimum. In order to display Wayland clients inside this compositor, the WAYLAND_DISPLAY
+environment variable needs to be set appropriately. Starting a client on the command line could be
+done like this:
+\badcode
+WAYLAND_DISPLAY=qtam-wayland-nested qmlscene client.qml -platform wayland
+\endcode
+Note that this works only in multi-process mode, since the nested compositor needs a real window as
+its root element.
+
+\section2 Crash Simulation and Recovery
+The crash application provides various means to force a crash in the application, like a
+segmentation fault. It utilizes a QML plugin implemented in C++, that provides the \c Terminator
+QML type to trigger crashes. The application manager will print the cause of the crash and other
+information like a backtrace. The System UI implements a basic form of crash recovery: it simply
+restarts the application. Note that this works only in mulit-process mode. In single process mode a
+crash will affect the entire (System UI) program.
+
+\section2 Two Top-Level Windows
+This application shows how multiple top-level windows can be displayed by having a QtObject as the
+application's root element.
+
+\section2 Native Widgets
+The native widgets application is based on \l{QWidget}s. In contrast to the other applications
+which are QML applications, this one uses the "native" runtime. Consequently, the application's
+entry point isn't a main QML file, but an executable. It is probably the most basic application,
+that still adheres to this particular System UI. It is just for illustrating the concept: the
+System UI needs a \c type window property to differentiate between normal windows and popups. Note
+that this works only in multi-process mode; naturally, application processes cannot be started in
+single-process mode.
+\endlist
+
+\section1 Code Structure
+In contrast to other application manager examples, which are purely based on QML, this example
+needs to be built necessarily. The code is structured in a way, that the resulting application
+folders only contain the needed artifacts to run the application. Hence they could be packaged and
+installed, as well (for instance to the \l{Desktop System UI Example}).
