# GT Prolog – QL

Attempting to write a review of GT-Prolog (GTP) has proved to be rather more difficult than anticipated. There is, first of all, the necessity for familiarization with a new language. This, of course, was to be expected. What was not foreseen was the difficulty in reading (or rather, interpreting) the accompanying manual.
