 In particular, typechecker and interpreter give a precise semantics.

+To run the checker and interpreter (which currently aren't working anyway),
+you need to generate External Core for all the base, integer and ghc-prim
+libraries. This can be done by adding "-fext-core" to the GhcLibHcOpts in
+your build.mk file, then running "make" under libraries/.
+Then you need to edit Driver.hs and change "baseDir" to point to your GHC
+libraries directory.

+Most recently tested with GHC 6.8.2. I make no claims of portability. --tjc
