XSB Prolog dialect support

This directory provides the library emulation for XSB. It is normally activated using the directive below or by loading a file with the .P extension.

:- expects_dialect(xsb).

The library files themselves are either SWI-Prolog module files or XSB module files. They are available through the XSB directive below after the xsb dialect is selected.

:- import Pred, ... from Library.

Providing a transparent user experience

The user may include the following in <config>/init.pl to activate XSB dialect support simply by loading .P files.

:- use_module(library(dialect/xsb/source)).
