KDE 4 is already insight and should be arriving around October. I am watching the news about this desktop system since a while and liked the fresh look of the new iconset. As Icons do not need to be compiled nor linked I thought it would be easy integrating them into my current Desktop. Doing so is really easy:
First, change to the KDE Icon directory (i.e. /usr/kde/3.5/share/icons/). To get the new Icons we will be using Subversion for checking them out of the repository. We’re doing this via console:
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs/pics/oxygen
As soon as the checkout is done, we can select the new icons via the usual control panels and there we go. If there are new things in subversion you can update your snapshot by changing into the new oxygen directory (in our example /usr/kde/3.5/share/icons/oxygen) for typing svn up there.
