# `make' implicit rules from creating a file called install from it | |
# when there is no Makefile. | |
# | |
# This script is compatible with the BSD install script, but was written | |
# from scratch. It can only install one file at a time, a restriction | |
# shared with many OS's install programs. | |
# set DOITPROG to echo to test this script | |
# Don't use :- since 4.3BSD and earlier shells don't like it. | |

In the 4th, create DIRECTORIES. | |
