.SH NAME
|
|
Lunzip \- decompressor for lzip files
|
|
.SH SYNOPSIS
|
|
.B lunzip
|
|
[\fIoptions\fR] [\fIfiles\fR]
|
|
.SH DESCRIPTION
|
|
Lunzip is a decompressor for lzip files. It is written in C and its
|
|
small size makes it well suited for embedded devices or software
|
|
installers that need to decompress files but do not need compression
|
|
capabilities. Lunzip is fully compatible with lzip\-1.4 or newer.
|
|
.PP
|
|
If the size of the output buffer is specified with the '\-\-buffer\-size'
|
|
option, lunzip uses the decompressed file as dictionary for distances
|
|
beyond the buffer size and is able to decompress any file using as
|
|
little memory as 50 kB, irrespective of the dictionary size used to
|
|
compress the file. Of course, the smaller the output buffer size used in
|
|
relation to the dictionary size, the more accesses to disk are needed
|
|
and the slower the decompression is. This 'low memory' mode only works
|
|
when decompressing to a regular file.
