# This is a wrapper around the find command that pretends find has a switch
# of the form -cp host:destination.  It presumes your find implements -ls.
# It uses tar to do the actual copy.  If your tar knows about the I switch
# you may prefer to use findtar, since this one has to do the tar in batches.
