can we deprecate and archive this?

it doesn't look like anybody is using this, ci has not a single ghc version that doesn't choke on it (at least here), and it seems small enough for it to be ok to inline it whenever it's needed in the future.

A project of mine used it back a while ago but I could easily enough resurrect the code I need in any given project, if needed.

I'm interested in keeping this alive since it looks pretty small.

Looks like it needs a bit more attention, migrating off travis and so. We could possibly host this as part of @haskell-nix org or keep it here if you don't mind.

I don't mind (and I don't think I should have a say in this). I just thought this looked like one of those things that everybody can write by themselves whenever they need it, because it's easier to write it than to find it. But there's not much harm in keeping it around either.
