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.
