* Changes in '51', 27-Aug-2016:
- LZMA.Encoding has been added; it is a standalone compressor,
see lzma_enc.adb for an example of use.
- Zip.Compress provides now LZMA_1, LZMA_2 methods. In other words, you
can use the LZMA compression with Zip.Create.
- Zip.Compress has also a "Preselection" method that selects
a compression method depending on hints like the uncompressed size.
- Zip.Compress.Deflate: Deflate_1 .. Deflate_3 compression is
slightly better.
The LZMA format, new in Zip-Ada, is especially good for compressing database data - be it in binary or text forms. Don't be surprised if the resulting archive represent only a few percents of the original data...
Enjoy!
