-# Nix flake for a Haskell CLI application
-
-This flake contains a Nix package and a development shell for a sample Haskell
-CLI application called `hello`.
-
-The Haskell package is wrapped with `generateOptparseApplicativeCompletions`,
-which adds shell completion scripts. These scripts will be automatically picked
-up if the resulting derivation is installed.
-
-The development shell provides the following tools for Haskell development:
-
