+TCP, version $version
+TCP stands for Tar Comparison Program here.
+It currently compares: BSD tar (bsdtar), GNU tar (gnutar) and star in archive
+creation, listing, extraction and archive-to-extracted comparison.
+Tcp prints out best time of n=$n repetitions.
+
+Tcp creates temporary archive named tcp.tar with $pax and some native
+(--seek/-no-fsync) options and extracts it to [\$3]/tcptmp/.
+If unset, third argument defaults to [\$2].
+After normal exit tcp removes tarball and extracted files.
+Tcp does not check filesystems destination directories are on for free space,
+so make sure there is enough space (a bit more than source_dir uses) for both:
+archive and extracted files.
+Do not use white space in arguments.
