+# 	Rules
+
+# In preparation for building the various libHS* libraries,
+# we create the interface files needed to boot their build.
+#
+# Note that the creation of IOBase, Main and GHC interface
+# files for umpteen ways is strictly not necessary, they're
+# all the same, but having the redundant files prevents us
+# from having to treat the said interface files specially
+# when creating the dependencies. 
+#
+# Note: if you change the *.hi-boot files, this will not be
+# picked up by the Makefile, you'll have to `make hi-boot'
+#
+# Note2: hsc will only read from ghc/GHC.hi regardless of 
+# which `way' you're compiling, so the copies of the GHC
+# interface file for the different ways are only there
+# to pacify `make'
+
+HIBOOTS=GHC Main IOBase
+
+hi-boot :
+	@for i in norm $(WAYS); do \
+		echo "Booting interface files for way $$i "; \
+		if [ "$$i" != "norm" ]; then \
+		   j="$${i}_hi"; \
+		else \
+		   j='hi'; \
+		fi; \
+		for ifile in $(HIBOOTS); do \

+		done; \
+	done
+	@touch ghc/IOBase.lhs
+
+boot :: hi-boot
+
+#-----------------------------------------------------------------------------
+# 	Installation; need to install .hi files as well as libraries
+#
+# The interface files are put inside the $(libdir), since they
+# might (potentially) be platform specific..
+#
+# Note: we use `override' here to ignore the setting of datadir
+# which may have been set on the command-line..naughty, as it
+# prevents `datadir' from being used from the command-line.
