/**
* 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:
*
* [!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
* ...
*
* 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:
*
*
* - cannotopenfile
*
- notification
*
- warning
*
- fatalerror
*
- catastrophe
