nroff การใช้

• It is the GNU replacement for the troff and nroff text formatters.
• TSC's nroff emulating formatter was ported to OS-9 by MicroWay, as well.
• RUNOFF is a direct predecessor of the roff and nroff document formatting programs of Unix, and their descendants.
• It also introduced several stability improvements beyond Research Unix, and support for the nroff and troff text formatters.
• When they got a Graphic Systems CAT phototypesetter, Ossanna modified " nroff " to support multiple fonts and proportional spacing.
• Part of the troff suite of Unix document layout tools, "'tbl "'is a preprocessor that formats tables in preparation for processing with troff / nroff.
• With " troff " came " nroff " ( they were actually almost the same program ), which was for producing output for line printers and character font changes.
• When the team got a Graphic Systems CAT phototypesetter for making camera-ready copy of professional articles for publication and patent applications, Ossanna wrote a version of " nroff " that would drive it.
• When they needed a more flexible language, a new version of " roff " called nroff ( " newer " roff " " ) was written, which provided the basis for all future versions.
• "' roff "'was the first Unix text-formatting computer program, the most important application run on the first machine specifically purchased to run UNIX, and a predecessor of the nroff and troff document processing systems.
• Also for the PDP-1 he wrote TJ-2 ( Type Justifying Program ), the predecessor of the troff and nroff page layout programs developed at Bell Labs, a T-Square, a drafting program that used a Spacewar ! controller for an input device.
• The product was announced in September 1988 with a baseline tag price of $ 595, although some utilities like uucp were included in a separate Extension package priced at $ 250 . nroff and troff for AIX were also sold separately in a Text Formatting System package priced at $ 200.
• Many universities wanted a general-purpose timesharing system that would meet the needs of students and researchers ( early versions of UNIX included free compilers for C, Fortran, and Pascal; at the time, offering even one free compiler was unprecedented . ) From its inception UNIX could drive high-quality typesetting equipment and later Postscript printers using the nroff / troff typesetting language, and this was also unprecedented for its time.
