# Carl Worth <cworth@east.isi.edu>
# based on a script by Steve Redler IV, steve@sr-tech.com 5-21-2001
# 2003-04-25 rea@sr.unh.edu
#   Updated to work on Familiar Pre0.7rc1, with busybox tar.
#   Note it Requires: binutils-ar (since the busybox ar can't create)
#   For UID debugging it needs a better "find".
