A Program for Compressing Files

Edit Package xz

The xz command is a very powerful program for compressing files.

* Average compression ratio of LZMA is about 30% better than that of
gzip, and 15% better than that of bzip2.

* Decompression speed is only little slower than that of gzip, being
two to five times faster than bzip2.

* In fast mode, compresses faster than bzip2 with a comparable
compression ratio.

* Achieving the best compression ratios takes four to even twelve
times longer than with bzip2. However. this doesn't affect
decompressing speed.

* Very similar command line interface to what gzip and bzip2 have.

- Update to version 5.0.5
  * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
    .lzma files that have less common settings in the headers
    (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
    size greater than 256 GiB).
  * xz:
    - Fixes and improvements to error handling.
    - Various fixes to the man page.
  * xzless: Fixed to work with "less" versions 448 and later
  * xzgrep: Made -h an alias for --no-filename. (forwarded request 183430 from namtrac)
