/**
 * @brief A KConfigSkeleton that populates itself based on KConfigXT XML
 *
 * This class allows one to ship an XML file and reconstitute it into a
 * KConfigSkeleton object at runtime. Common usage might look like this:
 *
 * \code
 * QFile file(xmlFilePath);
 * Plasma::ConfigXml appletConfig(configFilePath, &file);
 * \endcode
 *
 * Alternatively, any QIODevice may be used in place of QFile in the
 * example above.
 *
 * Currently the following data types are supported:
 *
 * @li bools
 * @li colors
 * @li datetimes
 * @li enumerations
 * @li fonts
 * @li ints
 * @li passwords
 * @li paths
 * @li strings
 * @li stringlists
 * @li uints
 * @li urls
 * @li doubles
 * @li int lists
 * @li longlongs
 * @li path lists
 * @li points
 * @li rects
 * @li sizes
 * @li ulonglongs
 * @li url lists
