If you mean troff, that was BWK and "..." was Osanna. (Not Been Laudin'.) The original was in PDP-11 Unix assembly language and made substantial use of tricks such as packing two character codes into a word. troff was rewritten again later (by BWK) to make a "device independent" version. I think the Plan 9 version represents one more overhaul to work better with "runes"; I rather lost track of it after it diverged from the DWB 2.0 version, which is the last one my org. paid for the right to use.
