I've been using a simplified set of SConscripts for the search module
which simply uses all .h's in include/ and include/*/ and all .cpps in
src and src/*/ rather than just a specified list. The removes the need
to run the make-sconscript script when you add headers. Unless anyone
objects I'll change the core scripts to do this. And then there will
be one less thing to keep in sync :-)
