3 * Mini tar implementation for busybox
5 * Modifed to use common extraction code used by ar, cpio, dpkg-deb, dpkg
6 * Glenn McGrath <bug1@optushome.com.au>
8 * Note, that as of BusyBox-0.43, tar has been completely rewritten from the
9 * ground up. It still has remnents of the old code lying about, but it is
10 * very different now (i.e., cleaner, less global variables, etc.)
