-Usage:
-
-  You define you custom builder script by adding all build steps to a list.
-  for example:
-       builder = writeScript "fsg-4.4-builder"
-               (textClosure [doUnpack addInputs preBuild doMake installPhase doForceShare]);
-
-  a step is defined by noDepEntry, fullDepEntry or packEntry.
-  To ensure that prerequisite are met those are added before the task itself by
-  textClosureDupList. Duplicated items are removed again.
-
-  See trace/nixpkgs/trunk/pkgs/top-level/builder-defs.nix for some predefined build steps
-
-  Attention:
-
-  let
-    pkgs = (import /etc/nixos/nixpkgs/pkgs/top-level/all-packages.nix) {};
-  in let
-    inherit (pkgs.stringsWithDeps) fullDepEntry packEntry noDepEntry textClosureMap;
-    inherit (pkgs.lib) id;
-
-    nameA = noDepEntry "Text a";
-    nameB = fullDepEntry "Text b" ["nameA"];
-    nameC = fullDepEntry "Text c" ["nameA"];
-
-    stages = {
-      nameHeader = noDepEntry "#! /bin/sh \n";
-      inherit nameA nameB nameC;
-    };
-  in
-    textClosureMap id stages
-    [ "nameHeader" "nameA" "nameB" "nameC"
-      nameC # <- added twice. add a dep entry if you know that it will be added once only [1]
-      "nameB" # <- this will not be added again because the attr name (reference) is used
-    ]
-
-  # result: Str("#! /bin/sh \n\nText a\nText b\nText c\nText c",[])
-
-  [1] maybe this behaviour should be removed to keep things simple (?)
