ditroff =3D Device Independent Troff

The original troff were hardwired to the C/A/T photo-typesetter which
by the time of SVR bare existed in the market anymore.

Ditroff took a configfile and emitted a documented output, which a
device-dependent postprocessor would convert into something the
actual hardware understood.

I think I wrote about a dozen ditroff config+preprocessor combos during
the late 1980ies.
