 *
 * @section common Core Classes
 *
 * @ref QtVisionIface : 
 *     The DCOP interface to QtVision.
 *
 * @ref QtVision
 *     A QObject that provides a high-level API to the TV.
 *
 * @section components Components
 *
 * @ref QtVisionPart :
 *     A KPart that displays a TV picture.
 *
 * @ref ChannelEditor :
 *     A widget for editing a suite of TV channels.
 *
 * @ref QtVisionWidget :
 *     A QWidget that displays a TV picture.
 *
 * @ref QtVisionApplet :
 *     A KPanelApplet that displays a TV picture.
 *
 * @ref QtVisionExtension :

 * @section lowlevel Low-Level API
 *
 * If you need to interact with a video device at a lower level than that
 * provided by the QtVision abstraction then you should use the V4LDev
 * class. This class (and those that inherit from it) provide a wrapper
 * around the various Video4Linux <a href="man:/ioctl">ioctl</a> calls.
 *
 * @ref V4LDev :
 *     A generic interface implemented by all video devices.
