+MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
+
+Introduction
+---------------------
+MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
+
+When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
+All possible work was done for compatibility.
+
+
+Background
+---------------------
+When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64 
+support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
+
+That was used as a starting point. And after that ZIP64 support was added to zip.c
+some refactoring and code cleanup was also done.
+
+
+Changed from MiniZip 1.0 to MiniZip 1.1
+---------------------------------------
+* Added ZIP64 support for unzip ( by Even Rouault )
+* Added ZIP64 support for zip ( by Mathias Svensson )
+* Reverted some changed that Even Rouault did.
+* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
+* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
+* Added BZIP Compress method for zip
+* Did some refactoring and code cleanup
+
+
+Credits
+
+ Gilles Vollant    - Original MiniZip author
+ Even Rouault      - ZIP64 unzip Support
+ Daniel Borca      - BZip Compression method support in unzip
+ Mathias Svensson  - ZIP64 zip support
+ Mathias Svensson  - BZip Compression method support in zip
+
+ Resources
+
+ ZipLayout   http://result42.com/projects/ZipFileLayout
+             Command line tool for Windows that shows the layout and information of the headers in a zip archive.
+             Used when debugging and validating the creation of zip files using MiniZip64
+
+
+ ZIP App Note  http://www.pkware.com/documents/casestudies/APPNOTE.TXT
+               Zip File specification
+
+
+Notes.
+ * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

 /* ioapi.h -- IO base function header for compress/uncompress .zip
-   files using zlib + zip or unzip API
+   part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
 
-   Version 1.01e, February 12th, 2005
+         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 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+               More if/def section may be needed to support other platforms
+    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
+                          (but you should use iowin32.c for windows instead)

+
+        Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
+  Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
+                                should only read the compressed/uncompressed size from the Zip64 format if

+  Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant

+                                Patch created by Daniel Borca
+
+  Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

+   part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
 
-   27 Dec 2004 Rolf Kalbermatter
-   Modification to zipOpen2 to support globalComment retrieval.

+
+         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
