Arguments:
f1 -- First file name
f2 -- Second file name
shallow -- treat files as identical if their stat signatures (type, size,
mtime) are identical. Otherwise, files are considered different
if their sizes or contents differ. [default: True]
Return value:
True if the files are the same, False otherwise.
This function uses a cache for past comparisons and the results,
with cache entries invalidated if their stat information
changes. The cache may be cleared by calling clear_cache().

ee eeeeeeeeeeed� Zdd� Zee�ZdS )r aM A class that manages the comparison of 2 directories.
dircmp(a, b, ignore=None, hide=None)
A and B are directories.
IGNORE is a list of names to ignore,
defaults to DEFAULT_IGNORES.
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.

a, b -- directory names
common -- list of file names found in both directories
shallow -- if true, do comparison based solely on stat() information
Returns a tuple of three lists:
files that compare equal
files that are different
filenames that aren't regular files.
