It is many, but it is what GNOME and KDE needs. It is gnome with the oo.o 
icons which pops the roof. The question is, since all these icons should be 
spec'ed at somepoint anyway, it's perhaps just as good to do it at once. In 
the GNOME case the icons already exists. The trouble of achieving conformance 
is organizational; to play diplomacy and contact projects, surf repositories, 
and get all these icons collected in one place -- and with the right 
names(that diagnosis tool is a must have). The problem is, if we go for 
something small, it won't work with GNOME, for example. I'm not convinced in 
this matter and I'll happily see someone clear my confusion.

Ok. Then the spec will basically say "if any icon should look differnt in rtl 
mode, create another icon and append '_rtl' to its name."

That sounds very interesting.
