Ann: Zip-Ada v.44

Ann: Zip-Ada v.44

[gautier_niouzes]

Hello! 

I am pleased to announce a new version of the Zip-Ada library.
URL: http://unzip-ada.sf.net/ . 

Major changes in the last version:

  - The libary provides now a complete toolset for managing Zip archives
      (creating, updating, extracting)
  - Zip_Streams: All methods now with pointer-free profiles
  - Zip.Create:
    - new Add_Compressed_Stream for copying entries from an archive
        to another one
    - file modification date and read-only attribute can be passed
        to Add_File 
    - archive creation date is used when entries are added which
        are from a memory buffer (Add_String)
    - compression method can be changed "on the fly", before
        adding new entries

Some features: 
- full sources are in Ada (no binding) 
- decompression for all Zip sub-formats up to BZip2 
- compression for all Zip sub-formats up to Deflate 
- unconditionally portable 
- input and output can be any stream (file, buffer,...) for archive 
creation as well as data extraction. 
- task safe 
- endian-neutral 

The zipada44.zip archive contains: 

* The full library sources (inside one directory: Zip_Lib), in Ada 95, 
using only Ada 95 standard's libraries 

* Some command-line demo / tools: 
  * ZipAda, a zipping tool 
  * UnZipAda, an unzipping utility 
  * Comp_Zip, compares two Zip files 
  * Find_Zip, searches a text string through contents of a Zip file 
  * ReZip.adb, optimizes compression of Zip archives 

NB: the ZipAda, UnZipAda, ReZip use a few non-Ada 95 library items. 

The tools can be found pre-built for Windows in zipada44-bin- 
win32.zip . 

Enjoy!
