  res = Net::HTTP.post_form(uri,
    { 'ips' => ARGV.join(' '),
      'type' => '', 'u' => '', 'p' => ''
    } )
  fstr = res.body
  fstr.gsub!("Edition Results<\/span><p>", "CHECKPOINT")
  fstr =~ /CHECKPOINT(.+?)<\/table>/m
  fields = $1.grep(/<(th|td)>/)
  fields.each do |f|
    f.strip!
    f.gsub!(/<[^>]+>/, "")
  end

  (0...13).each do |i|
    puts ". #{fields[i]}: #{fields[i+13]}"
