title: How do I create an .ics event with a title using ri_cal
body: <p>I'm using the <code>ri_cal</code> gem to create ics files. The gem's documentation suggests I do this:</p>
  
  <pre><code>RiCal.Calendar do |cal|
    cal.event do |event|
      event.description = "MA-6 First US Manned Spaceflight"
      event.dtstart =  DateTime.parse("2/20/1962 14:47:39")
      event.dtend = DateTime.parse("2/20/1962 19:43:02")
      event.location = "Cape Canaveral"
      event.add_attendee "john.glenn@nasa.gov"
      event.alarm do
        description "Segment 51"
      end
    end
  end
  </code></pre>
  
  <p>But when I open the .ics file this creates in OS X Calendar, the event has no title. Only the Description has been set as described.</p>
  
  <p>How do I set the event's title?</p>
