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

    or: $0 [OPTION]... -d DIRECTORIES...

 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.
