Downloaded, modified the permissions & rezipped the includemacro, as
an example.
Unfortunately, I have no idea at all about zip file format(s) or how
to output the header.
That said, playing with python zipinfo I suspect the information held
in external_attr is the villain;
it is always 0 in the downloaded archive but has a value in the re-
zipped one - whatever the value
means...
$ python2.4 -i -c 'import zipfile; z_downloaded = zipfile.ZipFile
("includemacro-r5399.zip"); z_rezipped = zipfile.ZipFile
("includemacro.zip")'
>>> for name in z_downloaded.namelist():
... print '\n', name
... print "*** downloaded", pformat(z_downloaded.getinfo
(name).__dict__)
... print "+++ re-zipped", pformat(z_rezipped.getinfo
(name).__dict__)
