title: Real-world examples of the Builder pattern
body: <p>I would like to see how is Builder pattern used in real world applications/APIs. The examples I found are all pizzas, cakes, cars et cetera (plus the parser example from the GoF book).</p>
  
  <p>Could you please tell me about some usages of this patten in real-world applications/APIs, preferably from the world of C++, .NET or PHP (as those are the languages I'm familiar with).</p>
  
  <p>Thanks.</p>
