+# There are two available APIs for a QML slideshow:
+#  - 1 (the default) loads the entire slideshow when the installation-
+#      slideshow page is shown and starts the QML then. The QML
+#      is never stopped (after installation is done, times etc.
+#      continue to fire).
+#  - 2 loads the slideshow on startup and calls onActivate() and
+#      onLeave() in the root object. After the installation is done,
+#      the show is stopped (first by calling onLeave(), then destroying
