+The MsgQueue project is a simple RTX Kernel based example
+for a simulated Cortex-M3 device
+
+Example functionality:
+ - Clock Settings:
+   - XTAL    =  12 MHz
+   - Core    =  12 MHz
+
+The simple RTX Kernel based example shows how to use a 
+message queue to send data from one thread to another.
+The message receiver thread prints the message contents
+to the debug output window.
+
+The MsgQueue example program is available for one target:
+
+  Simulation:          configured for a simulated on-chip Flash
