-# Bootstrapping
-
-# The stage1/stage2/stage3 business is quite delicate.  Here's how it works:
-# 
-#  - the variable $(stage) holds the current stage number.  To build a 
-#    particular stage, you say 'make stage=N' where N is 1, 2, or 3.
-#    N defaults to 1.
-#
-#  - for stage N, object files and .hi files are placed inside 
-#    the directory stageN, in subdirectories as per the sources.
-#
-#  - .hi-boot files are *linked* into the stageN tree, because in GHC 5.05+
-#    the .hi-boot file must reside in the same place as the .hi file.
-#
-#  - we use explicit -o and -ohi options to direct the output from C & 
-#    Haskell compilations.
-#
-#  - we generate a different .depend file for each build.  They need to be
-#    different, because each stage might include different files: stage1
-#    might not include GHCi, for example.  For each stage, a normal .depend
-#    file is generated, and then post-processed to add the correct stageN/
-#    prefix to each object and .hi filename.  The resulting .depend file
-#    is named .depend-$(stage).  See the end of this Makefile for details.
-#
-#  - normal implicit rules don't work any more, because they're of the form
-#
-#        %.o : %.hs 
-#
-#    whereas we really need 
-#
-#	 stageN/%.o : %.hs
-#
-#    so suffix.mk now defines the appropriate suffix rules when
-#    $(odir) is set to a non-empty value.  Here we set $(odir) to
-#    stage1, stage2, or stage3.
-#
-#  There are other plausible designs that might work, but each has different
-#  problems:
-#
-#  - using -odir and -hidir: GHC <= 4.08 doesn't support -hidir, and
-#    anyway -odir puts all the objects in one directory (strips off the
-#    subdirectory part), which eventually forces us to use VPATH to find
-#    the sources.  I have a really bad feeling about VPATH.
-#
-#  - invoke make in the stageN subdirectory.  This probably requires VPATH
-#    too.
-#
-#  - create a link tree.  The problem with requiring link trees is that 
-#    Windows doesn't support symbolic links.

-# Explicit dependencies
-
-# Some .hs files #include other source files, but since ghc -M doesn't spit out
-# these dependencies we have to include them manually.
-
-# We don't add dependencies on HsVersions.h, ghcautoconf.h, or ghc_boot_platform.h,
-# because then modifying one of these files would force recompilation of everything,
-# which is probably not what you want.  However, it does mean you have to be
-# careful to recompile stuff you need if you reconfigure or change HsVersions.h.
-
-# Aargh, these don't work properly anyway, because GHC's recompilation checker
-# just reports "compilation NOT required".  Do we have to add -no-recomp for each
-# of these .hs files?  I haven't done anything about this yet.
