scripts for finding available versions in nixpkgs
# Some nixpkgs query scripts inspired by #nixos chat.
# Goal: find the HASH that will let an install command like
# nix-env -i -f https://github.com/NixOS/nixpkgs/archive/HASH.tar.gz -A hledger hledger-web hledger-ui
# install the latest available build of the packages, on all platforms of interest.
# These scripts don't seem to quite do that but they help.
