+WARNING: Running pixz without the -t flag will cause it to treat the input as a tarball, as long as it looks vaguely tarball-like. This means if the file starts with at least 1024 zero bytes, pixz will assume it's empty, and truncate the output! If your input files aren't tarballs, run with -t or face possible data-loss.
