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.

I would not write non-copylefted software unless it is too simple to be

worth copylefting it, but one of the uses of the lzip format is the

interchange of information, and it is therefore desirable that even the

users of the most non-free platforms can share lzip files with everybody

else.
