Can we do this in a .py instead? And place both the list and the script in the
same file?
To make things easier, suggest putting directories in the list, then making the
py script filter the headers in the directory (accept all headers except
+Private ones). That way we won't have to always update the headers file. Should
support exporting individual headers too (there are some isolated ObjC headers
we might want to export).

Done.
