+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.
+
+Updating
+---
+
+```
+$ nix-prefetch-git https://github.com/ghcjs/ghcjs --rev refs/heads/ghc-8.2 \
+  | jq '{ url, rev, fetchSubmodules, sha256 }' \
+  > 8.2/git.json
+$ cat $(nix-build ../../../.. -A haskell.compiler.ghcjs82.genStage0 --no-out-link) > 8.2/stage0.nix
