uncozip
=======
This is a command and package to UNzip COrrupted ZIP file that does not have the central directory records.
Even when the archive is so large that `zip -FF Corrupted.zip --out New.zip` fails, sometimes uncozip succeeds.
( For example, the case Corrupted.zip is larger than 4GB )
The uncozip is also useful on non-Windows OSes to unpack archives with non-UTF8 filenames such as Shift_JIS.
(`uncozip -decode Shift_JIS foo.zip`)
Usage
-----
```
uncozip {OPTIONS} ZIPFILENAME [list...]
uncozip {OPTIONS} - [list...] < ZIPFILENAME
uncozip {OPTIONS} < ZIPFILENAME
```
* `-d string` the directory where to extract
* `-debug` Enable debug output
* `-strict` quit immediately on CRC-Error
* `-t` Test CRC32 only
* `-decode IANA-NAME` specify [IANA-registered-name][iana] to decode filename when UTF8 flag is not set (for example: `-decode Shift_JIS`)

===================================
Unlike "[archive/zip]", uncozip can
- read an archive from io.Reader.
( "[archive/zip]" requires archive's filename[^zip.OpenReader] or io.ReaderAt and size information[^zip.NewReader] )
- handle encrypted archive.
( You have to call [RegisterPasswordHandler] )
- decode filename from any encoding
( You have to call [RegisterNameDecoder] )
