+#
+# 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'
