sicstus:use_module/3

use_module(+Module, -File, +Imports) is det
use_module(-Module, +File, +Imports) is det: This predicate can be used to import from a named module while the file-location of the module is unknown or to get access to the module-name loaded from a file.
If both Module and File are given, we use Module and try to unify File with the absolute canonical path to the file from which Module was loaded. However, we succeed regardless of the success of this unification.
