The O'Reilly macro package was derived from the macros described in
Dougherty and O'Reilly "UNIX Text Processing" (Hayden 1988).  I
received a copy round 1993 for my book "Porting UNIX Software" (didn't
we shout in those days?), and when we released the book under Creative
Commons in 2005 or so, the macros were released with it.  It's
available online as

In passing I should mention that they required me to use those
macros.  At the time I wanted to use TeX, but they were "unwilling".
I used groff, and I've never used TeX since: a dead baby duck.
