Please, test it and report any bugs you find.

Plzip is a massively parallel (multithreaded) implementation of lzip. Plzip uses the compression library lzlib.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip uses a simplified form of LZMA (Lempel-Ziv-Markov chain-Algorithm) designed to achieve complete interoperability between implementations. The maximum dictionary size is 512 MiB so that any lzip file can be decompressed on 32-bit machines. Lzip provides accurate and robust 3-factor integrity checking. 'lzip -0' compresses about as fast as gzip, while 'lzip -9' compresses most files more than bzip2. Decompression speed is intermediate between gzip and bzip2. Lzip provides better data recovery capabilities than gzip and bzip2. Lzip has been designed, written, and tested with great care to replace gzip and bzip2 as general-purpose compressed format for Unix-like systems.

Plzip can compress/decompress large files on multiprocessor machines much faster than lzip, at the cost of a slightly reduced compression ratio (0.4 to 2 percent larger compressed files). Note that the number of usable threads is limited by file size; on files larger than a few GB plzip can use hundreds of processors, but on files smaller than 1 MiB plzip is no faster than lzip (not even at compression level -0).

Changes in this version:

* '-dvv' and '-tvv' now print (de)compressed sizes instead of compression ratio. (Sizes are more informative than compression ratio).

* Large numbers in option arguments are now accepted with underscore separators (-s 123_456_789).

  * Large numbers are now printed with underscore separators (123_456_789).

* By default, '--help' now prints a short help screen containing only the command-line options. For full help, call plzip with options '-v --help'.

* '--list' now can safely skip any trailing data added to a lzip file by the option '--append' of lziprecover.

* '--list' now prints '+t' after the number of members to indicate the presence of trailing data, and prints the size of the trailing data below the size of the last member.

* '-lvv' now prints a blank line between the list of members of each multimember file and the next file.

  * 'EXIT STATUS' now has its own section in the man page.
