.SH SYNOPSIS

.SH DESCRIPTION
-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.
+Tarlz is a combined implementation of the tar archiver and the lzip
+compressor. 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 adds an indexed lzip layer on top of the tar archive,
+making it possible to decode the archive safely in parallel. 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
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
