19 -----------
21 XZ Utils provide a general-purpose data-compression library plus
22 command-line tools. The native file format is the .xz format, but
23 also the legacy .lzma format is supported. The .xz format supports
25 context of XZ Utils. The primary filter is currently LZMA2. With
26 typical files, XZ Utils create about 30 % smaller files than gzip.

6 ----------
10 XZ Utils compress some files significantly worse than LZMA Utils.
11 This is due to faster compression presets used by XZ Utils, and
12 can often be worked around by using "xz --extreme". With some files
13 --extreme isn't enough though: it's most likely with files that

27 Add support for storing metadata in .xz files. A preliminary
29 metadata and data are wanted in the same .xz file, two or more
