+# ToDo List.
+#
+# Before we can merge the new build system into HEAD:
+#
+#   * finish installation
+#     * other documentation
+#     * create doc index and contents
+#     * Windows: should we have ghc-pkg-<version>?
+#     * should we be stripping things?
+#     * install libgmp.a, gmp.h
+#   * finish binary distributions
+#   * need to fix Cabal for new Windows layout, see
+#     Distribution/Simple/GHC.configureToolchain.
+#
+# As we merge the new build system into HEAD:
+#
+#   * remove old Makefiles, add new stubs for building in subdirs
+#     * utils/hsc2hs/Makefile
+#     * utils/haddock/Makefile
+#     * mk/oldconfig.mk.in
+#
+# Once the new build system is in HEAD, and before 6.12:
+#
+#   * docbook PDFs, e.g. "dblatex -T db2latex users_guide.xml"
+#   * GhcProfiled
+#   * optionally install stage3?
+#   * why does so much stuff get rebuilt after re-configuring?
+#   * shared libraries, way dyn
+#   * add pointers to wiki docs from the build system source
+#   * get HC bootstrapping working
+#   * add Makefiles for the rest of the utils/ programs that aren't built
+#     by default (need to exclude them from 'make all' too)
+#
+# Tickets we can now close, or fix and close:
+#
+#   * 912  build system doesn't have enough dependencies (it does now!)
+#   * 2744 check for presence of hsc2hs in ./configure
+#   * 2966 make sure --with-gcc does the right thing (#2966)
+#   * 3115 make ghc.cabal read-only
+#   * 2107 install the docs by default
+#   * 1693 make distclean
+#   * 2689 make maintainer-clean
+#   * 2619  bootstrapping using a newer GHC shouldn't fail
+#     for bogus reasons (picking the wrong version of the ghc package)
+#   * 2770 check which version of gcc we require
+#   * 3173 make install with DESTDIR
+
+# Possible cleanups:
+#
+#   * per-source-file dependencies instead of one .depend file?
+#   * eliminate undefined variables, and use --warn-undefined-variables?
+#   * perhaps we should make all the output dirs in the .depend rule, to
+#     avoid all these mkdirhier calls?
+#   * put outputs from different ways in different subdirs of distdir/build,
+#     then we don't have to use -osuf/-hisuf.  We would have to install
+#     them in different places too, so we'd need ghc-pkg support for packages
+#     of different ways.
+#   * make PACKAGES generated by configure or sh boot?
+#   * we should use a directory of package.conf files rather than a single
+#     file for the inplace package database, so that we can express
+#     dependencies more accurately.  Otherwise it's possible to get into
+#     a state where the package database is out of date, and the build
+#     system doesn't know.
+
+# NOTES on how to debug:
+#   make --debug=b --debug=m  shows dependencies
+#   make -p                   prints all generated makefile rules and variables
+#   make show VALUE=VAR       prints the value of VAR
+#   $(warning stuff)          prints stuff when reading the makefile
+
+# BUILD ORDER
+#
+#     * With bootstrapping compiler:
+#           o Build libraries/{hpc,extensible-exceptions,Cabal}
+#           o Build utils/ghc-pkg
+#           o Build utils/ghc-cabal
+#     * With bootstrapping compiler and ghc-cabal:
+#           o Build utils/hsc2hs
+#           o Build libraries/hpc
+#           o Build compiler (stage 1)
+#     * For each package:
+#	    o generate package-data.mk and inplace-pkg-info
+#           o register each package into inplace/lib/package.conf
+#           o generate .depend for each package
+#     * With stage 1:
+#           o Build libraries/*
+#           o Build utils/* (except haddock)
+#           o Build compiler (stage 2)
+#     * With stage 2:
+#           o Build utils/haddock
+#           o Build compiler (stage 3)
+#     * With haddock:

+# built early.  Having got the package-data.mk files built, we can
+# restart make with up-to-date information about all the packages
+# (this is phase 0).  The remaining problem is the .depend files:
+#
+#   - .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

+# compiler being able to do this, which is why we have to separate the
+# three phases above.
+
+# So this is the final ordering:
+
+# Phase 0 : all package-data.mk files
+#           (requires ghc-cabal, ghc-pkg, mkdirhier, dummy-ghc etc.)

+#           (requires hsc2hs)

+# Phase 3 : ghc/stage1/.depend
