title: How do I draw a line using Cocos2D-X?
body: <p>I have been playing around with Cocos2D-X on my computer, and I have got it to build the hello world program on all the devices I would like to be able to build it on.</p>
  
  <p>I know how to make the program display a sprite, and display a label, but I have not been able just to get the program to draw a line. How can I draw a line in Cocos2D-X?</p>
