 <documentation>About this example:
-------------------
Simple &quot;Blinky&quot; console application for workstations (Windows, Linux, MacOS)
(see &quot;QM Tutorial&quot; at: https://www.state-machine.com/qm/gs_tut.html)

This example demonstrates:
- Active object (Blinky) with state machine
- Board Support Package abstraction for portability
- BSP implementation for desktop OS (Windows, Linux, MacOS)
- Platform-independent main() function
- Makefile to build the generated code on desktop OS (Windows, Linux, MacOS)
- Customized tools for building the generated code directly from QM

Building the example:
---------------------
To build this example, you will need the QP/C framework installed on your computer and the GNU-GCC compiler. Both of them will be available if you install the QP-bundle from:

https://www.state-machine.com/#Downloads

Running the example:
--------------------
This example is a simple console application, which you can run from a terminal.

For more QM examples for QP/C see:
https://www.state-machine.com/qpc/exa.html</documentation>
