title: Set the version of a .jar application using Processing (Java)
body: <p>I've created an application (called Countdown) with Processing (Java). I exported the application as a .jar-file. If I run it on Mac OS X and click in the top left (on the titlebar) "About Countdown" it shows me a screen with the app's icon and underneath it says "Version 1.0 (1.0)".</p>

  <p>How do I change the version of the application in the Processing sketch?</p>
