# XSB test suite

This directory contains tests that are copied from XSB Prolog. Using XSB
tests was proposed by Theresa Swift as part as a Kyndi-initiated project
to get XSB and SWI-Prolog more compatible.   This project is carried out
by Jan Wielemaker, Theresa Swift,  David   Warren,  Benjamin  Grosof and
Fabrizio Riguzzi.

The original XSB tests use shell scripts   to drive the tests. This copy
is integrated into the  SWI-Prolog  test   framework  and  uses a Prolog
replacement of the test framework provided by `xsb_tests.pl`.

The XSB project is govered  by  the   LGPL  license.  This  allows us to
distribute these files with SWI-Prolog. As the   test files are not part
of user applications, these LGPL  tests  have   no  impact  on the BSD-2
