Just a step back here.  Some of the directories listed below belong to 
the FSF, but some don't.  I don't think anyone can be asking Klee to 
update non FSF code.  That's why I asked Klee to drop RDA from the 
original list.

I don't think we can guarentee that, but I think we can live with the 
consequences :-/
