Clearly the miltary ROFF borrowed a name and many basic features
from roff on Multics. But EQROFF is an intereting innovation. Its
output style is still used by modern math systems like Maple. (I'm
glad, though, that Cherry and Kernighan hadn't seen it when they
set out to do eqn.)  There was also a built-in analog of refer.
Quite a product.
