[comp.lang.prolog] Bertrand

Does anyone know where I can obtain an implementation of Bertrand?  
This is a constraint programming language created by William Leler 
and described in his book "Constraint Programming Languages - Their 
Specification and Implementation", Addison-Wesley, 1988.  Also, does 
anyone know if there have been any further developments along the lines 
of Bertrand or the Purdue Equational Interpreter (on which Bertrand is 
based)?  

Please email me at steinbac@umn-cs.cs.umn.edu.  

Thanks.
