     * This namespace provides a method for issuing events to a KNotifyServer
     * call KNotifyClient::event("eventname"); to issue it.
     * On installation, there should be a file called
     * $KDEDIR/share/apps/appname/eventsrc which contains the events.
     *
     * The file looks like this:
     * <pre>
     * [!Global!]
     * IconName=Filename (e.g. kdesktop, without any extension)
     * Comment=FriendlyNameOfApp
     *
     * [eventname]
     * Name=FriendlyNameOfEvent
     * Comment=Description Of Event
     * default_sound=filetoplay.wav
     * default_presentation=1
     *  ...
     * </pre>
     * default_presentation contains these ORed events:
     *	None=0, Sound=1, Messagebox=2, Logfile=4, Stderr=8
     *
     * You can also use the "nopresentation" key, with any the presentations
     * ORed.  Those that are in that field will not appear in the kcontrol
     * module.  This was intended for software like KWin to not allow a window-opening
     * that opens a window (e.g., allowing to disable KMessageBoxes from appearing)
     * If the user edits the eventsrc file manually, it will appear.  This only
     * affects the KcmNotify.
     *
     * You can also use the following events, which are system controlled
     * and do not need to be placed in your eventsrc:
     *
     *<ul>
     * <li>cannotopenfile
     * <li>notification
     * <li>warning
     * <li>fatalerror
     * <li>catastrophe
     *</ul>
