Troff is a typesetting system that is part of the Unix operating system. Originally developed in the early 1970s by Joe Ossanna and others at Bell Labs, Troff was designed to format text documents and is particularly well-suited for producing complex documents, such as technical papers and manuals. Troff works by processing a plain text file that contains formatting commands and producing output suitable for typesetting. It includes features for font selection, paragraph alignment, and various layout options.
