A few facts on productions systems.

1. Haunt consists of 1500 productions and requires 160K words of memory on a
KL10. (So Frumps is a bit bigger than Haunt.)

2. Expert systems (R1, XSEL and PTRANS) written in a similar language
consist of around 1500-2500 productions.

3. An expert system to perform VLSI design (DAA) consists of around 200
productions.
