-New build system for GHCJS 8.2
----
-
-`ghcjs-8.2` reworked the build system, and now comes with its own
-small package set of dependencies. This involves autogenerating
-several sources and cabal files, based on a GHC
-checkout. `callCabal2nix` is off limits, since we don't like "import
-from derivation" in nixpkgs. So there is a derivation that builds the
-nix expression that should be checked in whenever GHCJS is updated.
