def bundle_docker_dir(modify_docker_func, path):
    """
    Tars up a directory using the normal docker.util.tar method but
    first relpaces the contents of the Dockerfile found at path with
    the result of calling modify_docker_func with a string containing
    the complete contents of the docker file.


    For example to prepend the phrase "bogus header"  to a dockerfile
    we first create a function that takes the contents of the current
    dockerfile as it's contents.

    >>> def append_bogus(docker_content):
    ...   return "bogus header " + docker_content

    Then we can tar it up.. but first we'll need some test content.
    These routines create a  temporary directory containing the following
    3 files.

    ./Dockerfile
    ./bogus1
    ./bogus2

    >>> from shipwright import tar
    >>> path = join(tar.TEST_ROOT, 'Dockerfile')
    >>> _ = open(path, 'w').write(u'blah')

    >>> _ = open(join(tar.TEST_ROOT, 'bogus1'),'w').write('hi mom')
    >>> _ = open(join(tar.TEST_ROOT, 'bogus2'), 'w').write('hello world')


    Now we can call bundle_docker_dir passing it our append_bogus function to
    mutate the docker contents. We'll receive a file like object which
    is stream of the contents encoded as a  tar file (the format Docker
    build expects)

    >>> fileobj = bundle_docker_dir(append_bogus, tar.TEST_ROOT)

    Normally we'd just pass this directly to the docker build command
    but for the purpose of this test, we'll use tarfile to decode the string
    and ensure that our mutation happened as planned.


    First lets ensure that our tarfile contains our test files

    >>> t = tarfile.open(fileobj=fileobj)
    >>> t.getnames()  # doctest: +SKIP
    ['bogus1', 'bogus2', 'Dockerfile']

    And if we exctart the Dockerfile it starts with 'bogus header'

    >>> ti = t.extractfile('Dockerfile')
    >>> ti.read().startswith(b'bogus header')
    True

    Obviously a real mutation would ensure that the the contents
    of the Dockerfile are valid docker commands and not some
    bogus content.
