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