def initialize(options = {})
  @options = DEFAULT_OPTIONS.merge(options)

  @option_parser = OptionParser.new do |opts|
    opts.program_name   = 'tokenizer'
    opts.summary_indent = '  '

    opts.on('-h', '--help', 'Shows this help message') do
      show_help
    end

    opts.on('-v', '--version', 'Shows the current version') do
      show_version

    end

    opts.on('-p', '--plain', 'Treats the input as plain text') do
      @options[:kaf] = false
    end

    opts.separator <<-EOF

Examples:

  cat example.txt | #{opts.program_name} -l en # Manually specify the language
  cat example.kaf | #{opts.program_name}       # Uses the xml:lang attribute

Languages:

  * Dutch (nl)
  * English (en)
  * French (fr)
  * German (de)
  * Italian (it)
  * Spanish (es)

KAF Input:

  If you give a KAF file as an input (-k or --kaf) the language is taken from
  the xml:lang attribute inside the file. Else it expects that you give the
  language as an argument (-l or --language)

Sample KAF syntax:

  <?xml version="1.0" encoding="UTF-8" standalone="no"?>
  <KAF version="v1.opener" xml:lang="en">
    <raw>This is some text.</raw>
  </KAF>
    EOF
  end
end
