-    \note In \QC 2.7, \QMLD supports both Qt Quick 1 and Qt Quick 2. However,
-    the \QC packages that are not delivered with Qt 5 are still built with
-    Qt 4.8, and therefore do not contain qml2puppet, which is the external
-    process that is responsible for rendering Qt Quick 2. To develop Qt Quick 2
-    applications using \QMLD, download the Qt 5.0.1 packages and build
-    qml2puppet yourself. The sources for qml2puppet are located in
-    \c{qt-creator\share\qtcreator\qml\qmlpuppet\qml2puppet}. The qml2puppet is
-    installed to \c{qtbase\bin}. If you then configure Qt 5.0.1 for your
-    project, \QMLD picks up the qml2puppet and supports Qt Quick 2.0.
