16 # without express or implied warranty.
18 # Calling this script install-sh is preferred over install.sh, to prevent
19 # `make' implicit rules from creating a file called install from it
20 # when there is no Makefile.
22 # This script is compatible with the BSD install script, but was written
23 # from scratch. It can only install one file at a time, a restriction
24 # shared with many OS's install programs.
26 # Modified for INN by adding the -B option to request saving of the original
27 # file (if install is overwriting an existing file). -B takes an argument,
28 # the suffix to use. INN invokes this script as install-sh -B .OLD. Also
29 # modified to use cp -p instead of just cp to install programs when invoked
33 # set DOITPROG to echo to test this script
35 # Don't use :- since 4.3BSD and earlier shells don't like it.
39 # put in absolute paths if you don't have them in your path; or use env. vars.
