  44 Delete all versioned files and directories from a Git checkout to save
  45 disk space. If any files are modified, it waits until the checkout is
  46 clean before continuing. All files can be restored with "git checkout
  47 -f".
  48
  49 Usage: $progname -f [options]
  50
  51 Options:
  52
  53   -f, --force
  54     Actually delete the files. This option is mandatory to avoid
  55     accidentally deleting the files, even though it's easy to get them
  56     back.
  57   -h, --help
  58     Show this help.
  59   -q, --quiet
  60     Be more quiet. Can be repeated to increase silence.
  61   -v, --verbose
  62     Increase level of verbosity. Can be repeated.
  63   --version
  64     Print version information.
