Oxygen-Gtk is a port of the default KDE widget theme (Oxygen) to GTK.
Its primary goal is to ensure visual consistency between GTK and
Qt-based applications running under KDE. A secondary objective is to
also have a stand-alone nice looking GTK theme that behaves well in
other desktop environments.
From Fabian Raetz (thank!) via ports@, with additional tweaks and
okays from dcoppa@, stsp@ and me.
Also ajacoutot@ did take care of devel/gtk+2 port documentation part.
