<p>The ZIP file format is a common archive and compression standard. This module
provides tools to create, read, write, append, and list a ZIP file.  Any
advanced use of this module will require an understanding of the format, as
defined in <a class="reference external" href="http://www.pkware.com/documents/casestudies/APPNOTE.TXT">PKZIP Application Note</a>.</p>
<p>This module does not currently handle multi-disk ZIP files.
It can handle ZIP files that use the ZIP64 extensions
(that is ZIP files that are more than 4 GByte in size).  It supports
decryption of encrypted files in ZIP archives, but it currently cannot
create an encrypted file.  Decryption is extremely slow as it is
implemented in native Python rather than C.</p>
<p>The module defines the following items:</p>
