+Camera Example
+==============
+
+This example demonstrates a simple use of the camera. It shows a window with
+a buttoned labelled 'play' to turn the camera on and off. Note that
+not finding a camera, perhaps because gstreamer is not installed, will
+throw an exception during the kv language processing.
