		+	Remarks:
		+	* The filename //must// be the same as the name of the class -- this is enforced by Java compiler.
		+	* In one class multiple jobs can be submitted, either in sequence or in parallel.
		+	* A mismatch of types is usually detected by the compiler, but sometimes it is detected only at runtime. If that happens, an exception is raised and the program crashes.
