title: Regular expressions in an Objective-C Cocoa application
body: <p>Initial Googling indicates that there's no built-in way to do regular expressions in an Objective-C Cocoa application.</p>
  
  <p>So four questions:</p>
  
  <ol>
  <li><p>Is that really true?</p></li>
  <li><p>Are you kidding me?</p></li>
  <li><p>Ok, then is there a nice open-source library you recommend?</p></li>
  <li><p>What are ways to get close enough without importing a library, perhaps with the NSScanner class?</p></li>
  </ol>
