/* 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 !!
