# This old version is the only one that won't clobber synlinks, e.g.:
# someone moves /opt to /usr/opt and makes a symlink.  With newer
# versions of tar, installing any new package will remove the /opt
# symlink and plop down a new directory there.
# Well, there's a lot of other bugs (the remote stuff particularly I'm
# told is flaky) in tar-1.13, so it'll only be here now for use by the
# Slackware package utils.  And, we'll even let people remove it and
# the pkgutils will still try to work (but eventually they'll pay the
# price :)
