New in v.57 [rev. 799]:
  - UnZip: fixed bad decoding case for the Shrink (LZW) format,
        on some data compressed only by PKZIP up to v.1.10,
        release date 1990-03-15.
  - Zip.Create: added Zip_Entry_Stream_Type for doing output
        streaming into Zip archives.
  - Zip.Compress: Preselection method detects Audacity files (.aup, .au)
        and compresses them better.

Zip-Ada is a pure Ada library for dealing with the Zip compressed
archive file format. It supplies:

 - compression with the following sub-formats ("methods"):
     Store, Reduce, Shrink (LZW), Deflate and LZMA
 - decompression for the following sub-formats ("methods"):
     Store, Reduce, Shrink (LZW), Implode, Deflate, Deflate64,
     BZip2 and LZMA
 - encryption and decryption (portable Zip 2.0 encryption scheme)
 - unconditional portability - within limits of compiler's provided
     integer types and target architecture capacity
 - input archive to decompress can be any kind of indexed data stream
 - output archive to build can be any kind of indexed data stream
 - input data to compress can be any kind of data stream
 - output data to extract can be any kind of data stream
 - cross format compatibility with the most various tools and file formats
     based on the Zip format: 7-zip, Info-Zip's Zip, WinZip, PKZip,
     Java's JARs, OpenDocument files, MS Office 2007+,
     Google Chrome extensions, Mozilla extensions, E-Pub documents
     and many others
 - task safety: this library can be used ad libitum in parallel processing
 - endian-neutral I/O
