+     "Tarlz is a massively parallel (multi-threaded) combined implementation of
+the tar archiver and the lzip compressor.  Tarlz creates, lists, and extracts
+archives in a simplified and safer variant of the POSIX pax format compressed
+with lzip, 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.")
