/**
 * Convenience access to certain properties and features of the
 * window manager.
 *
 * This class is not supposed to be instantiated.  It exists mostly as
 * a namespace for the static member functions.
 *
 * In KDE 2 and KDE 3, communication with the windowmanager is done with the
 * NET-protocol, a common window manager specification designed by
 * various authors of X11 window managers (including those of the KDE
 * project).  The full specification can be found in
 * kdebase/kwin/wm-spec/
 *
 * To access features of the NET-protocol, use the classes NETRootInfo
 * and NETWinInfo.
 *
 * The purpose of this class is to to provide easy access to the
 * most-commonly used NET-features with a simpler, KDEish interface.
 *
 * In addition, it encapsulates KDE functionality not yet provided by
 * the NET hints.  Currently that is invokeContextHelp() and
 * setSystemTrayWindowFor() only.
 *
 * @short Class for interaction with the window manager.
