.SH NAME
lziprecover \- recovers data from damaged lzip files
.SH SYNOPSIS
.B lziprecover
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Lziprecover \- Data recovery tool and decompressor for the lzip format.
.PP
Lziprecover can repair perfectly most files with small errors (up to one
single\-byte error per member), without the need of any extra redundance
at all. Losing an entire archive just because of a corrupt byte near the
beginning is a thing of the past.
.PP
Lziprecover can also produce a correct file by merging the good parts of
two or more damaged copies, extract data from damaged files, decompress
files and test integrity of files.
.PP
Lziprecover provides random access to the data in multimember files; it
only decompresses the members containing the desired data.
.PP
Lziprecover is not a replacement for regular backups, but a last line of
defense for the case where the backups are also damaged.

.PP
If no file names are given, or if a file is '\-', lziprecover 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...
.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 lziprecover to panic.
