20 # Calling this script install-sh is preferred over install.sh, to prevent
21 # `make' implicit rules from creating a file called install from it
22 # when there is no Makefile.
23 #
24 # This script is compatible with the BSD install script, but was written
25 # from scratch. It can only install one file at a time, a restriction
26 # shared with many OS's install programs.
