+# On Hackage every package description shows a category "Distributions" which
+# lists a "NixOS" version.
+# This script uploads a csv to hackage which will update the displayed versions
+# based on the current versions in nixpkgs. This happens with a simple http
+# request.
+
+# For authorization you just need to have any valid hackage account. This
+# script uses the `username` and `password-command` field from your
+# ~/.cabal/config file.
+
+# e.g. username: maralorn
+#      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.)
+# Those fields are specified under `upload` on the `cabal` man page.
