#NAME
#  lntree - copy directory tree via cpio
#
#SYNOPSIS
#  lntree olddir newdir
#
#DESCRIPTION
#  This makes a "linked copy" of olddir to newdir.  That is, cpio's "l"
#  option is used to make the new files linked to the old, so the only
#  really new things that are created are the directories.
