I'm planning out how to port Minix to L4 and I can't find any of the hearders.

I have CVS'd just about everything on your downloads page yet ./l4/include, ./l4/lib and ./l4/bin do not exist.
I feel that many of the choices regarding the layout of the source code and the usage of the more sophisticated tools only serve to obfuscate the system to new users. =(
