Re: Equations

[M Douglas McIlroy]

groff ships with Eric Raymon's extended manual for pic, but nothing similar
for eqn.

If the AT&T release would permit it, and Gnu would honor AT&T's terms, a
Kernighan/Cherry
document could be distributed with groff.

K&C documents are widely available online. Source text is at
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/doc/eqn. At the very
least a reference should be given in eqn(1). Inexplicably, The Texbook is
listed instead.
