How do I set permissions (attributes) on a file in a ZIP file using Python's zipfile module?

Question

When I extract files from a ZIP file created with the Python zipfile module, all the files are not writable, read only etc.

The file is being created and extracted u

This seems to work (thanks Evan, putting it here so the line is in context):

buffer = "path/filename.zip"  # zip filename to write (or file-like object)
name = "folder/data.txt"      # name of file inside zip 
bytes = "blah blah blah"      # contents of file inside zip

zip = zipfile.ZipFile(buffer, "w", zipfile.ZIP_DEFLATED)
info = zipfile.ZipInfo(name)
info.external_attr = 0777 << 16L # give full access to included file
zip.writestr(info, bytes)
zip.close()

I'd still like to see something that documents this... An additional resource I found was a note on the Zip file format: http://www.pkware.com/documents/casestudies/APPNOTE.TXT
