/* zip.c -- IO on .zip files using zlib
- Version 1.01e, February 12th, 2005
+ Version 1.1, February 14h, 2010
+ part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
- 27 Dec 2004 Rolf Kalbermatter
- Modification to zipOpen2 to support globalComment retrieval.
+ Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
- Copyright (C) 1998-2005 Gilles Vollant
+ Modifications for Zip64 support
+ Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
- Read zip.h for more info
+ For more info read MiniZip_info.txt
+
+ Changes
+ Oct-2009 - Mathias Svensson - Remove old C style function prototypes
+ Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
+ Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
+ Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
+ It is used when recreting zip archive with RAW when deleting items from a zip.
+ ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
+ Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
+ Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
