.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.
+Lziprecover is a data recovery tool and decompressor for files in the lzip
+compressed data format (.lz). Lziprecover is able to repair slightly damaged
+files, 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 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.
+Lziprecover can remove the damaged members from multimember files, for
+example multimember tar.lz archives.
.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.
