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>)
