   or: $0 [OPTION]... SRCFILES... DIRECTORY

In the 1st form, copy SRCFILE to DSTFILE.

In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.

In the 4th, create DIRECTORIES.

Options:

     --help     display this help and exit.

     --version  display version info and exit.

  -c            (ignored)

  -C            install only if different (preserve the last data modification time)

  -d            create directories instead of installing files.

  -g GROUP      $chgrpprog installed files to GROUP.

  -m MODE       $chmodprog installed files to MODE.

  -o USER       $chownprog installed files to USER.

  -s            $stripprog installed files.

  -t DIRECTORY  install into DIRECTORY.

  -T            report an error if DSTFILE is a directory.
