2#
3# install - install a program, script, or datafile
4# This comes from X11R5.
5#
6# Calling this script install-sh is preferred over install.sh, to prevent
7# `make' implicit rules from creating a file called install from it
8# when there is no Makefile.
9#
10# This script is compatible with the BSD install script, but was written
11# from scratch.
12#
13#

16# set DOITPROG to echo to test this script

18# Don't use :- since 4.3BSD and earlier shells don't like it.

22# put in absolute paths if you don't have them in your path; or use env. vars.
