Creation of an assembly

Every compilation creates either an ''assembly'' or a ''module'' in C#. It is possible to add other modules with the ''assembly linker'' (al). A speciality of Java is to create a *.class file for each class, which is not the case in C#. The creation can be activated by compiler switches, like csc /addmodule:Y.netmodule A.cs that yields a new A.exe with Y added to this assembly.
