tarlz \- creates tar archives with multimember lzip compression
.SH SYNOPSIS
.B tarlz

.SH DESCRIPTION
-Tarlz \- Archiver with multimember lzip compression.
+Tarlz is a small and simple implementation of the tar archiver. By default
+tarlz creates, lists and extracts archives in a simplified posix pax format
+compressed with lzip on a per file basis. Each tar member is compressed in
+its own lzip member, as well as the end\-of\-file blocks. This method is fully
+backward compatible with standard tar tools like GNU tar, which treat the
+resulting multimember tar.lz archive like any other tar.lz archive. Tarlz
+can append files to the end of such compressed archives.
+.PP
+The tarlz file format is a safe posix\-style backup format. In case of
+corruption, tarlz can extract all the undamaged members from the tar.lz
+archive, skipping over the damaged members, just like the standard
+(uncompressed) tar. Moreover, the option '\-\-keep\-damaged' can be used to
+recover as much data as possible from each damaged member, and lziprecover
+can be used to recover some of the damaged members.
