The document class requires that it is an extended Sprite or MovieClip, or any other class type that inherits from either of these objects.

For the sake of simplicity, this book refers to the document class and not to the main application file. Although their names differ, their usage is exactly the same.

Flex Builder and Flash Builder have the same workflow to get the document class up and running. However, the Flash IDE takes another approach. Let's start by explaining how it is done in the Flash IDE.
