/* unzip.h -- IO for uncompress .zip files using zlib
   Version 0.15 beta, Mar 19th, 1998,

   Copyright (C) 1998 Gilles Vollant

   This unzip package allow extract file from .ZIP file, compatible with PKZip 2.04g
     WinZip, InfoZip tools and compatible.
   Encryption and multi volume ZipFile (span) are not supported.
   Old compressions used by old PKZip 1.x are not supported

   THIS IS AN ALPHA VERSION. AT THIS STAGE OF DEVELOPPEMENT, SOMES API OR STRUCTURE
   CAN CHANGE IN FUTURE VERSION !!
   I WAIT FEEDBACK at mail info@winimage.com
