Neutrino-GUI - DBoxII-Project
Copyright (C) 2001 Steffen Hehn 'McClean'
Homepage: http://dbox.cyberphoria.org/
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.
