All still VERY primitive, in fact even more primitive since some stuff got re-horked after the meeting, and still needs working on. Won't actually compile out of the box, but the tweaks should be pretty obvious for any body sufficiently daring. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@4427 a592a061-630c-0410-9148-cb99ea01b6c8
