About:

    Language detection for various languages such as English and Dutch. This
    command reads input from STDIN. Output can be a language code as plain text,
    a KAF document containing the input text and language code, or a list of
    probabilities.

Example:

    cat some_file.kaf | language-identifier
          EOF

          separator "\nOptions:\n"

          on :v, :version, 'Shows the current version' do
            abort "language-identifier v#{VERSION} on #{RUBY_DESCRIPTION}"
          end

          on :'no-kaf', 'Disables KAF output'

          run do |opts, args|
            enable_kaf   = true

            if opts[:'no-kaf']
              enable_kaf = false
            end

            identifier = LanguageIdentifier.new(
              args:  args,
              kaf:   enable_kaf,
              probs: false,
            )

            input = STDIN.tty? ? nil : STDIN.read

            puts identifier.run(input)
          end
        end
