A Program for Compressing Files

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 5.0.4
  * liblzma:
    - Fix lzma_index_init(). It could crash if memory allocation
      failed.
    - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
      filter is used and the application only provides exactly as
      much output space as is the uncompressed size of the file.
    - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
      check if the last call to lzma_code() really returned
      LZMA_STREAM_END, which made the program think that truncated
      files are valid.
    - New example programs in doc/examples (old programs are now in
      doc/examples_old). These have more comments and more detailed
      error handling.
  * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
  * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
    incorrectly printed the filename also in the "foo (x/x)" format.
  * Fix exit status of "xzdiff foo.xz bar.xz".
  * Fix exit status of "xzgrep foo binary_file".
  * Fix portability to EBCDIC systems.
  * Fix a configure issue on AIX with the XL C compiler. See INSTALL
    for details.
  * Update French, German, Italian, and Polish translations (forwarded request 143030 from rudi_m)
