+//!

+//! A very simple ``hello world'' example written using the TivaWare Graphics

+//! Library widgets.  It displays a button which, when pressed, toggles

+//! display of the words ``Hello World!'' on the screen.  This may be used as

+//! a starting point for more complex widget-based applications.
