8 This unzip package allow creates .ZIP file, compatible with PKZip 2.04g
9 WinZip, InfoZip tools and compatible.
10 Multi volume ZipFile (span) are not supported.
11 Encryption compatible with pkzip 2.04g only supported
12 Old compressions used by old PKZip 1.x are not supported
14 For uncompress .zip file, look at unzip.h
