 A Stack executable makes use of Cabal (the library) through a small 'Setup'
 executable that it compiles from Haskell source code. The executable compiles
 that code with a dependency on the version of Cabal that ships with the
 specified GHC compiler. Each release of Stack will normally aim to support all
