-/* zip.c -- IO on .zip files using zlib
- Version 1.1, February 14h, 2010
- part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
-
- Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
-
- Modifications for Zip64 support
- Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
-
- 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 automatically 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
