-# We carefully engineer things so that we can build the

-#
-#   - .depend files in libraries need the stage 1 compiler to build
-#   - ghc/stage1/.depend needs compiler/stage1 built
-#   - compiler/stage1/.depend needs the bootstrap libs built

-# GHC 6.11+ can build a .depend file without having built the

-# compiler being able to do this, which is why we have to separate the

-# So this is the final ordering:
