/* zip.h -- IO for compress .zip files using zlib   Version 1.01e, February 12th, 2005   Copyright (C) 1998-2005 Gilles Vollant   This unzip package allow creates .ZIP file, compatible with PKZip 2.04g     WinZip, InfoZip tools and compatible.   Multi volume ZipFile (span) are not supported.   Encryption compatible with pkzip 2.04g only supported   Old compressions used by old PKZip 1.x are not supported  For uncompress .zip file, look at unzip.h   I WAIT FEEDBACK at mail info@winimage.com   Visit also http://www.winimage.com/zLibDll/unzip.html for evolution   Condition of use and distribution are the same than zlib :  This software is provided 'as-is', without any express or implied  warranty.
