About:

Component for tagging the polarity of elements in a KAF document. This
command reads input from STDIN.

Examples:

Processing a KAF file:

    cat some_file.kaf | polarity-tagger

Displaying the underlying kernel options:

    polarity-tagger -- --help

      EOF

      separator "\nOptions:\n"

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

      run do |opts, args|
        tagger = PolarityTagger.new(:args => args)
        input  = STDIN.tty? ? nil : STDIN.read

        puts tagger.run(input)
      end
