FILE LIST -
             recoverExcDemo.c

DESCRIPTION -
	     Demonstrates using signals to allow a task to recover gracefully
	     from an exception.

RUNNING DEMO -
	     Place the recoverExcDemo.c in your <Tornado> dir. Depending on
	     the target you have, define the CPU in your compile line and
	     use the Makefile in the BSP dir. to compile.

             To run this code invoke the function recoverDemo().

CAVEAT    -  This code fails on a mv1604 board.
