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 \fB\-0\fR)
or compress most files more than bzip2 (lzip \fB\-9\fR). 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.
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, chosen to maximize safety and
interoperability. Lzip can compress about as fast as gzip (lzip \fB\-0\fR) or
compress most files more than bzip2 (lzip \fB\-9\fR). Decompression speed is

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.

The bidimensional parameter space of LZMA can't be mapped to a linear
scale optimal for all files. If your files are large, very repetitive,
etc, you may need to use the \fB\-\-dictionary\-size\fR and \fB\-\-match\-length\fR
options directly to achieve optimal performance. For example, \fB\-9m64\fR
usually compresses executables more (and faster) than \fB\-9\fR.

To extract all the files from archive 'foo.tar.lz', use the commands
\&'tar \fB\-xf\fR foo.tar.lz' or 'pdlzip \fB\-cd\fR foo.tar.lz | tar \fB\-xf\fR \-'.
.PP
Exit status: 0 for a normal exit, 1 for environmental problems (file
not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
invalid input file, 3 for an internal consistency error (eg, bug) which
caused pdlzip to panic.
.PP
Pdlzip includes public domain compression/decompression code from the LZMA
SDK (Software Development Kit) written by Igor Pavlov.
