"""\
bundlebuilder.py -- Tools to assemble MacOS X (application) bundles.

This module contains two classes to build so called "bundles" for
MacOS X. BundleBuilder is a general tool, AppBuilder is a subclass
specialized in building application bundles.

[Bundle|App]Builder objects are instantiated with a bunch of keyword
arguments, and have a build() method that will do all the work. See
the class doc strings for a description of the constructor arguments.

The module contains a main program that can be used in two ways:

  % python bundlebuilder.py [options] build
  % python buildapp.py [options] build

Where "buildapp.py" is a user-supplied setup.py-like script following
this model:

  from bundlebuilder import buildapp
  buildapp(<lots-of-keyword-args>)
