[Lzip-bug] Pdlzip 1.13 released

[Antonio Diaz Diaz]

I am pleased to announce the release of pdlzip 1.13.

Pdlzip is a permissively licensed implementation of the lzip data 
compressor, intended for those who can't distribute (or even use) GPL 
licensed Free Software. The name of pdlzip comes from 'public domain lzip'. 
Pdlzip is written in C and is compatible with lzip 1.4 or newer.

Lzip is a lossless data compressor with a user interface similar to the one 
of gzip or bzip2. Lzip uses a simplified form of the 'Lempel-Ziv-Markov 
chain-Algorithm' (LZMA) stream format to maximize interoperability. 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 can compress about as fast as gzip (lzip -0) or compress most 
files more than bzip2 (lzip -9). Decompression speed is intermediate between 
gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery 
perspective. Lzip has been designed, written, and tested with great care to 
replace gzip and bzip2 as the standard general-purpose compressed format for 
Unix-like systems.

Pdlzip is also able to decompress legacy lzma-alone (.lzma) files.

Pdlzip includes public domain (de)compression code from the LZMA SDK 
(Software Development Kit) written by Igor Pavlov.

This release is also GPG signed. You can download the signature by appending 
'.sig' to the URL. If the 'gpg --verify' command fails because you don't 
have the required public key, then run this command to import it:

Changes in version 1.13:

  * File diagnostics have been reformatted as 'PROGRAM: FILE: MESSAGE'.

  * Diagnostics caused by invalid arguments to command-line options now 
show the argument and the name of the option.

  * The option '-o, --output' now preserves dates, permissions, and 
ownership of the file when (de)compressing exactly one file.

  * The variable MAKEINFO has been added to configure and Makefile.in.

  * It has been documented in INSTALL that when choosing a C standard, the 
POSIX features need to be enabled explicitly:
  ./configure CFLAGS+='--std=c99 -D_XOPEN_SOURCE=500'


Please send bug reports and suggestions to lzip-bug@nongnu.org
