  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 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.
    -p            pass -p to $cpprog.
    -s            $stripprog installed files.
    -S SUFFIX     attempt to back up existing files, with suffix SUFFIX.
    -t DIRECTORY  install into DIRECTORY.
    -T            report an error if DSTFILE is a directory.
  
  Environment variables override the default commands:
    CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
    RMPROG STRIPPROG
  
  By default, rm is invoked with -f; when overridden with RMPROG,
  it's up to you to specify -f if you want it.
  
  If -S is not specified, no backups are attempted.
