-//! This example demonstrates the use of StellarisWare to setup the clocks
-//! and toggle GPIO pins to make the LED's blink. This is a good place to
-//! start understanding your launchpad and the tools that can be used to
-//! program it. See http://www.ti.com/stellaris-launchpad/project0 for more
