SWI-Prolog 7.4.2 Reference Manual: Section 6.7

## 6.7 Composing modules from other modules

The predicates in this section are intended to create new modules from the content of other modules. Below is an example to define a composite module. The example exports all public predicates of `module_1`, `module_2` and `module_3`, pred/1 from `module_4`, all predicates from `module_5` except do_not_use/1 and all predicates from `module_6` while renaming pred/1 into mypred/1.

    :- module(my_composite, []).
    :- reexport([ module_1,
                  module_2,
                  module_3
                ]).
    :- reexport(module_4, [ pred/1 ]).
    :- reexport(module_5, except([do_not_use/1])).
    :- reexport(module_6, except([pred/1 as mypred])).

reexport(+Files)
  Load and import predicates as use_module/1 and re-export all imported predicates. The reexport declarations must immediately follow the module declaration.
reexport(+File, +Import)
  Import from File as use_module/2 and re-export the imported predicates. The reexport declarations must immediately follow the module declaration.
