title: What is view engine? What does it actually do?
body: <p>I started learning ASP.NET MVC3. </p>
  
  <p>So, while reading tutorials  online and in books, I came across this term <em>"view engine"</em> quite frequently. I don't know what it is. </p>
  
  <p>What does it actually do? </p>
  
  <p>Why should it matter to me at all?</p>
