Tarlz creates, lists and extracts -archives in a simplified posix pax format compressed with lzip, keeping the -alignment between tar members and lzip members. 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.
