+# Brief explanation of the bootstrap logic:
+#
+# Previous ghc ebuilds have been split into two: ghc and ghc-bin,
+# where ghc-bin was primarily used for bootstrapping purposes.
+# From now on, these two ebuilds have been combined, with the
+# binary USE flag used to determine whether or not the pre-built
+# binary package should be emerged or whether ghc should be compiled
+# from source.  If the latter, then the relevant ghc-bin for the
+# arch in question will be used in the working directory to compile
+# ghc from source.
+#
+# This solution has the advantage of allowing us to retain the one
+# ebuild for both packages, and thus phase out virtual/ghc.
+
+# Note to users of hardened gcc-3.x:
+#
+# If you emerge ghc with hardened gcc it should work fine (because we
+# turn off the hardened features that would otherwise break ghc).
+# However, emerging ghc while using a vanilla gcc and then switching to
+# hardened gcc (using gcc-config) will leave you with a broken ghc. To
+# fix it you would need to either switch back to vanilla gcc or re-emerge
+# ghc (or ghc-bin). Note that also if you are using hardened gcc-3.x and
+# you switch to gcc-4.x that this will also break ghc and you'll need to
+# re-emerge ghc (or ghc-bin). People using vanilla gcc can switch between
+# gcc-3.x and 4.x with no problems.
