Pdlzip 1.11-rc3 is ready for testing here

The sha256sums are:
2f5766ca93051c41a8b71bcf1325846f44382dbd2c22414c5c9e7cc0d4568828 pdlzip-1.11-rc3.tar.lz 4221bffa91f54469e962082a5d90bc6d2784331781dc2f17c17ddc4e9939389d pdlzip-1.11-rc3.tar.gz

Please, test it and report any bugs you find.

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 (hope)fully 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 LZMA stream format chosen to maximize safety and interoperability. 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.

The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability.

Pdlzip is also able to decompress legacy lzma-alone (.lzma) files. Lzma-alone is a very bad format; it is essentially a raw LZMA stream. If you keep any lzma-alone files, it is advisable to recompress them to lzip format. Lziprecover can convert some lzma-alone files to lzip format without recompressing.

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

Changes in this version:

* Option '-o, --output' now behaves like '-c, --stdout', but sending the output unconditionally to a file instead of to standard output. See the new description of '-o' in the manual. This change is backwards compatible only when (de)compressing from standard input alone. Therefore commands like:
  pdlzip -o foo.lz - bar < foo
must now be split into:
  pdlzip -o foo.lz - < foo
  pdlzip bar
or rewritten as:
  pdlzip - bar < foo > foo.lz

* When using '-c' or '-o', pdlzip now checks whether the output is a terminal only once.

If you care about interoperability and long-term archiving, please help me replace xz with lzip. See http://www.nongnu.org/lzip/lzip_benchmark.html#xz1
