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 5.0.3 * liblzma fixes: - A memory leak was fixed. - lzma_stream_buffer_encode() no longer creates an empty .xz Block if encoding an empty buffer. Such an empty Block with LZMA2 data would trigger a bug in 5.0.1 and older (see the first bullet point in 5.0.2 notes). When releasing 5.0.2, I thought that no encoder creates this kind of files but I was wrong. - Validate function arguments better in a few functions. Most importantly, specifying an unsupported integrity check to lzma_stream_buffer_encode() no longer creates a corrupt .xz file. Probably no application tries to do that, so this shouldn't be a big problem in practice. - Document that lzma_block_buffer_encode(), lzma_easy_buffer_encode(), lzma_stream_encoder(), and lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. - The return values of the _memusage() functions are now documented better. * Fix command name detection in xzgrep. xzegrep and xzfgrep now correctly use egrep and fgrep instead of grep. * French translation was added.
