In the 4th, create DIRECTORIES.

  -C            install only if different (preserve the last data modification time)
  -d            create directories instead of installing files.

  -o USER       $chownprog installed files to USER.
  -s            $stripprog installed files.
  -t DIRECTORY  install into DIRECTORY.
