37# Calling this script install-sh is preferred over install.sh, to prevent
38# `make' implicit rules from creating a file called install from it
39# when there is no Makefile.
40#
41# This script is compatible with the BSD install script, but was written
42# from scratch. It can only install one file at a time, a restriction
43# shared with many OS's install programs.
