41 # when there is no Makefile.
43 # This script is compatible with the BSD install script, but was written
44 # from scratch. It can only install one file at a time, a restriction
45 # shared with many OS's install programs.

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