 * KNewStuff download widget.
 *
 * The download widget will present items to the user
 * for installation, updates and removal.
 * Preview images as well as other meta information can be seen.
 *
 * \section knsrc knsrc Files
 * The Dialog is configured by a .knsrc file containing the KHotNewStuff configuration.
 * Your application should install a file called: <em>$KDEDIR/share/config/appname.knsrc</em>
 *
 * The file could look like this for wallpapers:
 * <pre>
   [KNewStuff3]
   ProvidersUrl=http://download.kde.org/ocs/providers.xml
   Categories=KDE Wallpaper 1920x1200,KDE Wallpaper 1600x1200
   StandardResource=wallpaper
   Uncompress=archive
 * </pre>
 *
 * Uncompress can be one of: always, never or archive:
 * <ol>
 * <li>always: assume all downloaded files are archives and need to be extracted</li>
 * <li>never: never try to extract the file</li>
 * <li>archive: if the file is an archive, uncompress it, otherwise just pass it on</li>
 * </ol>
 *
 * You have different options to set the target install directory:
 *   <ol><li>StandardResource: standard ressouce dir, such as <em>.kde/share/wallpapers</em>.
 *           This is what KStandardDirs::locateLocal(name) will return.</li>
 *       <li>TargetDir: a directory in the share/apps section, such as <em>.kde/share/apps/wallpapers</em>.
 *           This is what KStandardDirs::locateLocal("data", name) will return.</li>
 *       <li>XdgTargetDir: a directory in the $XDG_DATA_HOME directory such as <em>.local/share/wallpapers</em>.
 *   </ol>
