Like this:

  module X.C (module A.B.C) where
  import A.B.C

Well, how do you currently understand some program distributed without
the full source for all the libraries it uses?  You need instructions
for where to find those libraries - the only new thing is that now you
also need grafting info.  It's just an extension to the dependency info
that comes with some source code.
