+# Brief explanation of the bootstrap logic:
+#
+# ghc requires ghc-bin to bootstrap.
+# Therefore, 
+# (1) both ghc-bin and ghc provide virtual/ghc
+# (2) virtual/ghc *must* default to ghc-bin
+# (3) ghc depends on virtual/ghc
+#
+# This solution has the advantage that the binary distribution
+# can be removed once an forall after the first succesful install
+# of ghc.
