RASTA is a framework for describing tasks on a computer system. RASTA makes it easy for individual developers or teams of developers to write consistent dialogs and wizards for end-user tasks like product installation and configuration. To build a wizard or dialog, the developer creates a description of the task in XML files, and then Rasta's back-end library parses the XML files and hands them off to Rasta's front-end client which renders them to the end-user.
