+ Sometimes emacsWithPackages is not enough, as
+ this package set has some priorities imposed on packages (with
+ the lowest priority assigned to Melpa Unstable, and the highest for
+ packages manually defined in
+ pkgs/top-level/emacs-packages.nix). But you
+ can't control this priorities when some package is installed as a
+ dependency. You can override it on per-package-basis, providing all
+ the required dependencies manually - but it's tedious and there is
+ always a possibility that an unwanted dependency will sneak in
+ through some other package. To completely override such a package
+ you can use overrideScope.
