Latest draft of API is here: http://contextlib2_dev.readthedocs.org/en/latest/index.html#contextlib2.ExitStack

An updated version of the "I forgot I could use multiple context managers in a with statement" example:

    with ExitStack() as stack:
        src = open(source)
        stack.callback(src.close)
        dest = open(destination, 'w')
        stack.callback(dest.close)
        copy(src, dest)

The example of opening a collection of files remains unchanged (aside from s/ContextStack/ExitStack/).
