The gui currently does nothing else than providing a search window that sends the search string to the browser The gui is started when YaCy is started with the option -g or --gui, like ./startYACY.sh -g The gui will primary be used to provide a 'real' macintosh version that can be started and operated like any other macintosh application. A special mac application wrapper will follow. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7021 6c8d7289-2bf4-0310-a012-ef5d649a1542pull/1/head
