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.
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.
45 # set DOITPROG to echo to test this script
47 # Don't use :- since 4.3BSD and earlier shells don't like it.
50 # put in absolute paths if you don't have them in your path; or use env. vars.
