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.

51 # Don't use :- since 4.3BSD and earlier shells don't like it.
54 # put in absolute paths if you don't have them in your path; or use env. vars.
