<text, tool> /T'rof/ or /trof/ The grey eminence of Unix text processing; a formatting and phototypesetting program, written originally in PDP-11 assembly code and then in barely-structured early C by the late Joseph Ossanna, modelled after the earlier ROFF which was in turn modelled after Multics' RUNOFF by Jerome Saltzer (*that* name came from the expression "to run off a copy"). A companion program, nroff, formats output for terminals and line printers. In 1979, Brian Kernighan modified troff so that it could drive phototypesetters other than the Graphic Systems CAT. His paper describing that work ("A Typesetter-independent troff", AT&T CSTR #97) explains troff's durability. After discussing the program's "obvious deficiencies - a rebarbative input syntax, mysterious and undocumented properties in some areas, and a voracious appetite for computer resources" and noting the ugliness and extreme hairiness of the code and internals, Kernighan concludes: None of these remarks should be taken as denigrating Ossanna's accomplishment with TROFF. It has proven a remarkably robust tool, taking unbelievable abuse from a variety of preprocessors and being forced into uses that were never conceived of in the original design, all with considerable grace under fire. The success of TeX and desktop publishing systems have reduced troff's relative importance, but this tribute perfectly captures the strengths that secured troff a place in hacker folklore; indeed, it could be taken more generally as an indication of those qualities of good programs that, in the long run, hackers most admire. groff is GNU's implementation of roff in C++.

Typesetter New Run-OFF (Reference: Unix)

troff (), short for "typesetter roff", is the major component of a document processing system developed by Bell Labs for the Unix operating system. troff and the related nroff were both developed from the original roff.

TRON is a debugging command in old dialects of the BASIC programming language. It is an abbreviation of TRace ON.

In computing, Pic is a domain-specific programming language by Brian Kernighan for specifying diagrams in terms of objects such as boxes with arrows between them. The pic compiler translates this description into concrete drawing commands.

is a series of video games published by Nintendo and created by game designer Shigeru Miyamoto in 1981. The series mainly consists of two genres: single-screen platform/action puzzle games featuring the gorilla Donkey Kong as the main antagonist, and side-scrolling platform games where Donkey Kong and his clan of other apes are the protagonists and player characters who usually battle the crocodilian villain King K.
