About:

    Rule base POS tagging using TreeTagger, supports various languages such as
    Dutch and English. This command reads input from STDIN.

    cat some_file.kaf | tree-tagger
          EOF

          separator "\nOptions:\n"

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

          on :'no-time', 'Disables adding of dynamic timestamps'

          run do |opts, args|
            if opts[:'no-time']
              args = args + ['--no-time']
            end

            tagger = TreeTagger.new(:args => args)
            input  = STDIN.tty? ? nil : STDIN.read

            puts tagger.run(input)
          end
