The list Exports must contain valid export specifications as described in export/1. It defines the first part of the module's interface, subsequent export and reexport directives can add to that.
Unlike with module/1, the new module does not implicitly import anything. In particular, no built-in predicates are available inside the module unless a language-module is specified in the Language argument. This module (or a list of them) is imported just after the new module is created.
The main use of this feature is to write different parts of a program in different language dialects. For example, a module that contains code written in ISO-Prolog should be encapsulated in a module starting with:
:- module(mymodule, , iso).In this module, ISO language features can be used, but not (all) Eclipse features.
The system does not allow the atom  to be used as a module name! If  is given as the Language argument, it indicates the empty list, rather than a module with name .
% A module in C-Prolog syntax: :- module(m, [p/1], cprolog). p("this is a list not a string").
