+/* zip.h -- IO for compress .zip files using zlib
+Version 1.01, May 8th, 2004
+
+Copyright (C) 1998-2004 Gilles Vollant
+
+This unzip package allow creates .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
+
+For uncompress .zip file, look at unzip.h
