# COMMON OVERRIDES FOR THE HASKELL PACKAGE SET IN NIXPKGS
#
# This file contains haskell package overrides that are shared by all
# haskell package sets provided by nixpkgs and distributed via the official
# NixOS hydra instance.
#
# Overrides that would also make sense for custom haskell package sets not provided
# as part of nixpkgs and that are specific to Nix should go in configuration-nix.nix
