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