    # source: the source directory inside a time machine backup
    # target: the target directory in which to copy the reconstructed
    # directory trees. Created if it does not exists.
    #
    # Details:
    #
    # Time machine implements directory hard links by creating an
    # empty file in place of the directory and storing in its
    # "number of hard links" metadata attribute a pointer to a
    # real directory in "/.HFS Private directory data^M" named
    # "dir_$number".
    #
    # This script reconstructs a plain directory tree from this
    # really ugly apple hack. Tested on a 650GB backup from OSX
    # 10.6 mounted on a Linux 3.2.0-38 Ubuntu box. YMMV.
