.SH NAME
pdlzip \- reduces the size of files
.SH SYNOPSIS
.B pdlzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Pdlzip \- A "public domain" version of the lzip data compressor
also able to decompress legacy lzma\-alone (.lzma) files.
Lzma\-alone is a very bad format. If you keep any lzma\-alone files, it is
advisable to recompress them to lzip format.
Pdlzip \- A permissively licensed implementation of the lzip data
compressor also able to decompress legacy lzma\-alone (.lzma) files.
.PP
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 lzma\-alone files to lzip format
without recompressing.

If no file names are given, pdlzip compresses or decompresses
from standard input to standard output.
If no file names are given, or if a file is '\-', pdlzip compresses or
decompresses from standard input to standard output.
Numbers may be followed by a multiplier: k = kB = 10^3 = 1000,
Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
Dictionary sizes 12 to 27 are interpreted as powers of two, meaning 2^12
to 2^27 bytes.
.PP
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\-\-match\-length\fR and \fB\-\-dictionary\-size\fR
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.
