Classes:
    dircmp

Functions:
    cmp(f1, f2, shallow=1) -> int
    cmpfiles(a, b, common) -> ([], [], [])

    Arguments:

    f1 -- First file name

    f2 -- Second file name

    shallow -- Just check stat signature (do not read the files).
               defaults to 1.

    Return value:

    True if the files are the same, False otherwise.

    This function uses a cache for past comparisons and the results,
    with a cache invalidation mechanism relying on stale signatures.

    dircmp(a,b,ignore=None,hide=None)
      A and B are directories.
      IGNORE is a list of names to ignore,
        defaults to ['RCS', 'CVS', 'tags'].
      HIDE is a list of names to hide,
        defaults to [os.curdir, os.pardir].

    High level usage:
      x = dircmp(dir1, dir2)
      x.report() -> prints a report on the differences between dir1 and dir2
       or
      x.report_partial_closure() -> prints report on differences between dir1
            and dir2, and reports on common immediate subdirectories.
      x.report_full_closure() -> like report_partial_closure,
            but fully recursive.

    Attributes:
     left_list, right_list: The files in dir1 and dir2,
        filtered by hide and ignore.
     common: a list of names in both dir1 and dir2.
     left_only, right_only: names only in dir1, dir2.
     common_dirs: subdirectories in both dir1 and dir2.
     common_files: files in both dir1 and dir2.
     common_funny: names in both dir1 and dir2 where the type differs between
        dir1 and dir2, or the name is not stat-able.
     same_files: list of identical files.
     diff_files: list of filenames which differ.
     funny_files: list of files which could not be compared.
     subdirs: a dictionary of dircmp objects, keyed by names in common_dirs.
