	Neutrino-GUI  -   DBoxII-Project

	Copyright (C) 2001 Steffen Hehn 'McClean'

	Kommentar:

	Diese GUI wurde von Grund auf neu programmiert und sollte nun vom
	Aufbau und auch den Ausbaumoeglichkeiten gut aussehen. Neutrino basiert
	auf der Client-Server Idee, diese GUI ist also von der direkten DBox-
	Steuerung getrennt. Diese wird dann von Daemons uebernommen.
