The man page roff(7) incorrectly attributes roff to Joe Ossanna.
Ossanna wrote nroff and troff, but roff preceded that work. The name
roff was first used to distinguish a rewrite for Multics from the
original runoff, probably because both were maintained on CTSS. I
wrote an extended roff in BCPL for GECOS and kept the Multics name.
Ken and/or Dennis rewrote the BCPL program in assembly language for
Unix. There never was a pure runoff for Unix.
