// This example is done using the
// eclipse-dsl-mars-1 distribution with the 
// xtext_2.8.4.v201508050135
//
// we use the standards for a new xtext project which creates a project as: org.xtext.example.mydsl
// and we generate the xtext artifacts running the GenerateMyDsl.mwe2
//
// under the project, we create a new folder "models_xmi" for DSL files as well as the generated xmi files
// in that directory, we create DSL file testMYDSL.mydsl as:
/*
Hello PAUL!
Hello Peter!
Hello Martin!
*/
// in src/org.xtext.example.mydsl we create a new Java Class with name "Main" 
// and check "public static void main(String[] args)" in the wizard

// and this is the code in this Main.java file (note the "throws Exception")
