+.SH NAME
+tarlz \- creates tar archives with multimember lzip compression
+.SH SYNOPSIS
+.B tarlz
+\fI\,operation \/\fR[\fI\,options\/\fR] [\fI\,files\/\fR]
+.SH DESCRIPTION
+Tarlz is a massively parallel (multi\-threaded) combined implementation of
+the tar archiver and the lzip compressor. Tarlz uses the compression library
+lzlib.
+.PP
+Tarlz creates, lists, and extracts archives in a simplified and safer
+variant of the POSIX pax format compressed in lzip format, keeping the
+alignment between tar members and lzip members. The resulting multimember
+tar.lz archive is fully backward compatible with standard tar tools like GNU
+tar, which treat it like any other tar.lz archive. Tarlz can append files to
+the end of such compressed archives.
+.PP
+Keeping the alignment between tar members and lzip members has two
+advantages. It adds an indexed lzip layer on top of the tar archive, making
+it possible to decode the archive safely in parallel. It also minimizes the
+amount of data lost in case of corruption.
+.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.
