# 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;

# extraPrefs = self: {

# monadControl

|

# This will build mmorph and monadControl, and have the hoogle installation

|
# refer to their documentation via symlink so they are not garbage collected.
