This  program defines  a predicate,  'grexpand', for  expanding Definite
Clause Grammar Rules into Prolog clauses. These are the standard form of
DCG rules, for which a translator is built-in to many Prologs.


The translator is essentially the same as that published in "Programming
in Prolog", by Clocksin and Mellish. [JNP]
