/*
# Updating
To update the list of packages from MELPA Stable,
1. Clone https://github.com/ttuegel/emacs2nix
2. Clone https://github.com/milkypostman/melpa
3. Run `./melpa-stable-packages.sh PATH_TO_MELPA_CLONE` from emacs2nix.
Error messages about missing versions are normal; most packages in
MELPA do not have a stable version.
4. Copy the new melpa-stable-packages.json file into Nixpkgs
5. `git commit -m "melpa-stable-packages $(date -Idate)"`
