 ## Easing
 
-Corona uses a different signature for its built-in easing functions than the ones that come with gtween, but gtween can use them with the @transitionEase@ property (see the example above) to tell gtween.lua to use one of the [easing functions](http://developer.anscamobile.com/content/easing) designed for use with Corona's [transitions](http://developer.anscamobile.com/content/transitions). Use @ease@ (same as ActionScript) to use one of gtween's easing functions.
