-This module contains two classes to build so called "bundles" for MacOS X.
-:class:`BundleBuilder` is a general tool, :class:`AppBuilder` is a subclass
-specialized in building application bundles.
-
-These Builder objects are instantiated with a bunch of keyword arguments, and
-have a :meth:`build` method that will do all the work.
-
-The module also contains a main program that can be used in two ways::
-
-   % python bundlebuilder.py [options] build
-   % python buildapp.py [options] build
-
-where :file:`buildapp.py` is a user-supplied setup.py-like script following this
-model::
-
-   from bundlebuilder import buildapp
-   buildapp(<lots-of-keyword-args>)
