Description
Pdlzip is a lossless data compressor with a user interface similar to
the one of lzip, bzip2 or gzip.
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.
Pdlzip uses the lzip file format; the files produced by pdlzip are
(hope)fully compatible with lzip-1.4 or newer. Pdlzip is in fact 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").
Lzip is a lossless data compressor with a user interface similar to the
one of gzip or bzip2. 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
