#SYNOPSIS
#	Cp [opt] file... target
#	Lc [opt] file... target
#	Ln [opt] file... target
#	Mv [opt] file... target
#
#DESCRIPTION
# This is like the Unix command with the  lower-case  names,  but  it
# does a recursive rename (via Rm) on the targets first. Note that it
# doesn't complain if the target already exists. It also works if the
# target  is  a  directory, including the case where the file already
# exists.
#
# This has been rewritten in C, but it's often useful  to  have  this
# script  version around for bootstrapping purposes.  There are still
# some potential problems, such as the lack of the basename and  test
# commands in some libraries. We use /bin/test because of problems in
# the shell's builtin [...] syntax on some systems.
