Short Description:

HUProlog is an almost 100 per cent straight implementation of standard
Edinburgh syntax Prolog as described in Clocksin and Mellish's ``Programming
in Prolog'' (Springer Verlag) and a host of other works.  HU-Prolog is most
definately NOT a toy Prolog.  The authors and myself are all professional AI
and computer science research workers, and rely on HU-Prolog for a variety
of large-scale Prolog programming tasks.  It is definately one of the fastest
purely interpreted Prolog's around (the only faster one I know of is the
Edinburgh NIP implementation).  WAM-based compiling Prolog's are faster, but
at the price of greatly increased memory requirements.  Even then ``real
programs'' as opposed to benchmarks rarely run more than twice as fast.
Eventually I (or someone else) may port Sicstus or SB Prolog [see a067] for
RISC-OS, in the meantime HU is as good as it gets.
