# Install not only the Hoogle library and executable, but also a local Hoogle
# database which provides "Source" links to all specified 'packages' -- or the
# current Haskell Platform if no custom package set is provided.
#
# It is intended to be used in config.nix similarly to:
#
# { packageOverrides = pkgs: rec {
#
# haskellPackages =
# let callPackage = pkgs.lib.callPackageWith haskellPackages;
# in pkgs.recurseIntoAttrs (pkgs.haskellPackages.override {
# extraPrefs = self: {
# hoogleLocal = pkgs.haskellPackages.hoogleLocal.override {
# packages = with pkgs.haskellPackages; [
# mmorph
# monadControl
# ]
# };
# };
# });
# }}
#
# This will build mmorph and monadControl, and have the hoogle installation
# refer to their documentation via symlink so they are not garbage collected.
