Listing 1: Make a compressed uuencoded cpio archive

#!/bin/sh
#
#       mkarc
#
#       Make an archive suitable for RCS check-in.  The archive must be
#       compressed and in text form.  To extract at any location with any
#       name, create the archive with relative path names.  Use cpio's
#       compatibility option to avoid tar's incompatible design.
