Running HYPROLOG requires a Prolog system (see Versions and downloads; left menu). It is the sole responsibility of any HYPROLOG user to clear any possible legal issues with the suppliers of these Prolog systems.
The developers take no responsibility for any consequences of the use of this software.
For possible commercial applications, or if any doubts concerning these conditions, please write to the implementor.
HYPROLOG has been thought out by Henning Christiansen and Veronica Dahl and implemented by Henning Christiansen.
