#NAME
#  cptree - copy directory tree via cpio
#
#SYNOPSIS
#  cptree olddir newdir
#
#DESCRIPTIONo
#  Copy the contents of olddir to newdir, making newdir if necessary.
#
#  The copy is done by cpio; we just set up its parameters and to the
#  necessary cd's. The main point in putting this into a script is so
#  that we can use the natural syntax and  have  it  work  correctly.
#  This  can  be done with "cp -r" on most Unix-like systems, but the
#  syntax is counterintuitive and  often  takes  many  tries  to  get
#  right.  This script does it the obvious way.
