/*
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
