+    \internal
+    \class QmlTimeLine
+    \ingroup group_animation
+    \brief The QmlTimeLine class provides a timeline for controlling animations.
+
+    QmlTimeLine is similar to QTimeLine except:
+    \list
+    \i It updates QmlTimeLineValue instances directly, rather than maintaining a single
+    current value.
+
+    For example, the following animates a simple value over 200 milliseconds:
+    \code
+    QmlTimeLineValue v(<starting value>);
+    QmlTimeLine tl;
+    tl.move(v, 100., 200);
+    tl.start()
+    \endcode
+
+    If your program needs to know when values are changed, it can either
+    connect to the QmlTimeLine's updated() signal, or inherit from QmlTimeLineValue
+    and reimplement the QmlTimeLineValue::setValue() method.
+
+    \i Supports multiple QmlTimeLineValue, arbitrary start and end values and allows
+    animations to be strung together for more complex effects.
+
+    For example, the following animation moves the x and y coordinates of
+    an object from wherever they are to the position (100, 100) in 50
+    milliseconds and then further animates them to (100, 200) in 50
+    milliseconds:
+
+    \code
+    QmlTimeLineValue x(<starting value>);
+    QmlTimeLineValue y(<starting value>);
+
+    QmlTimeLine tl;
+    tl.start();
+
+    tl.move(x, 100., 50);
+    tl.move(y, 100., 50);
+    tl.move(y, 200., 50);
+    \endcode
+
+    \i All QmlTimeLine instances share a single, synchronized clock.
+
+    Actions scheduled within the same event loop tick are scheduled
+    synchronously against each other, regardless of the wall time between the
+    scheduling.  Synchronized scheduling applies both to within the same
+    QmlTimeLine and across separate QmlTimeLine's within the same process.
+
+    \endlist
+
+    Currently easing functions are not supported.
