Libarchive is a programming library that can create and read several
different streaming archive formats, including most popular tar variants
and several cpio formats.
bsdtar is an almost fully GNU tar-compatible frontend for libarchive.
It is one of the fastest tar implementations and supports many advanced
features not found elsewhere.
* Option --owner can be used in copy-out mode, allowing to uniformly
override ownership of the files being added to the archive.
* Symlinks were handled incorrectly in copy-out mode.
* Fix handling of large files.
* Fix setting the file permissions in copy-out mode.
* Honor umask when creating intermediate directories, not specified
in the archive.
* Fix archivation of sparse files in posix mode.
* Fix operation of --verify --listed-incremental.
* Fix --occurrence.
* Scope of --transform and --strip-components options.
* End-of-volume script can send the new volume name to tar.
p7zip is a port of 7-zip for *nix platforms.
7-zip is a file archiver with a high compression ratio.

* Use 'mktemp' rather than 'tempfile' in bzdiff.
* Tighten up a couple of assertions in blocksort.c following automated
analysis.
