  message="""Hello.

This is a demonstration of the WrappedText object, which was created to allow users of VisionEgg to include large blocks of text in their programs. While this stimulus has many limitations, it should be useful for presenting on-screen instructions in experiments.

While you are welcome to modify this file to extend its functionality, I hope you consider sharing any such modifications with the VisionEgg community.
