title: How do I open my perspective on first launch after the user installs my Eclipse Feature
body: <p>I'm building Eclipse plugins and delivering them via a p2 repository as an Eclipse Feature. </p>
  
  <p>One of my plugins contributes its own perspective via the org.eclipse.ui.perspectives extension point, and it works fine.</p>
  
  <p>Everything is running smoothly.</p>
  
  <p>But what I really want is for my perspective to open when the user first launches his/her Eclipse after my feature is installed.  And then on the second launch, this behavior goes away.  I don't want to annoy the user by opening my perspective every time they launch Eclipse.</p>
  
  <p>Is there an easy way to do this?</p>
  
  <p>Thanks for your time.</p>
