4# On Hackage every package description shows a category "Distributions" which
5# lists a "NixOS" version.
6# This script uploads a csv to hackage which will update the displayed versions
7# based on the current versions in nixpkgs. This happens with a simple http
8# request.

10# For authorization you just need to have any valid hackage account. This
11# script uses the `username` and `password-command` field from your
12# ~/.cabal/config file.
13
14# e.g. username: maralorn
15# password-command: pass hackage.haskell.org (this can be any command, but not an arbitrary shell expression. Like cabal we only read the first output line and ignore the rest.)
16# Those fields are specified under `upload` on the `cabal` man page.
