use_module in XSB Prolog

Question

I am porting http libraries from SWI Prolog to XSB Prolog. I have to port the following statement:

use_module(library(settings)).

to XSB. Can someone please tell me how to do this. I understand that porting is not trivial. I need to use set_setting, current_setting etc. I am not sure if there is an equivalent function existing in XSB.

Your help is greatly appreciated.
