#{executable} has two modes of operation:

1. If no files are listed, it will read from standard input and write to
   standard output.
2. If files are listed, it will modify each file in place, overwriting it
   with the beautified output.

The following options are available:

END
  opts.on(
    "-t", "--tab-stops NUMBER", Integer,
    "Set number of spaces per indent (default #{options[:tab_stops]})"
  ) do |num|
    options[:tab_stops] = num
  end
  opts.on(
    "-e", "--stop-on-errors",
    "Stop when invalid nesting is encountered in the input"
  ) do |num|
    options[:stop_on_errors] = num
  end
  opts.on(
    "-h", "--help",
    "Display this help message and exit"
  ) do
    puts opts
    exit
  end
end
parser.parse!

if ARGV.any?
  ARGV.each do |path|
    input = File.read(path)
    temppath = path + ".tmp"
    File.open(temppath, "w") do |output|
