- * (2) Write a default constructor and
- * call the default constructor of the base class.

* public void main(String[] args) {
* System.out.println("Hello MSG");
* }

* }
* The name of your process must be declared in the deployment file of your simulation.
* For the exemple, for the previouse process Slave this file must contains a line :
* <process host="Maxims" function="Slave"/>, where Maxims is the host of the process
* Slave. All the process of your simulation are automaticaly launched and managed by Msg.
* A process use tasks to simulate communications or computations with another process.
