NAME

       proof - troff output interpreter

SYNOPSIS

       proof [ -mmag ] [ -/nview ] [ -F dir ] [ -d ] [ file ]

DESCRIPTION

       Proof reads troff(1) intermediate language from file or standard input and simulates the resulting pages on the screen.

       After a page of text is displayed, proof pauses for a command from the keyboard.  The typed commands are:

       newline	 Go on to next page of text.

       -	 Go back to the previous page.

       q	 Quit.

       pn	 Print	page  n.   An  out-of-bounds  page  number means the end nearer to that number; a missing number means the current page; a
		 signed number means an offset to the current page.

       n	 Same as pn.

       c	 Clear the screen, then wait for another command.

       mmag	 Change the magnification at which the output is printed.  Normally it is printed with magnification .9; mag=.5 shrinks it to half
		 size; mag=2 doubles the size.

       xval	 Move everything val screen pixels to the right (left, if val is negative).

       yval	 Move everything val screen pixels down (up, if val is negative).

       /nview	 Split	the window into nview pieces.  The current page goes into the rightmost, bottommost piece, and previous pages are shown in
		 the other pieces.

       -F dir	 Use dir for fonts instead of /lib/font/bit.

       d	 Toggle the debug flag.

       These commands are also available, under slightly different form, from a menu on button 3.  The pan menu item allows arbitrary  positioning
       of  the	page:  after selecting pan, press the mouse button again and hold it down while moving the page to the desired location.  The page
       will be redisplayed in its entirety when the button is released.

       The m, x, y, F, /, and d commands are also available as command line options.

NAME

       troff, nroff - text formatting and typesetting

SYNOPSIS

       troff [ option ...  ] [ file ...  ]

       nroff [ option ...  ] [ file ...  ]

DESCRIPTION

       Troff  formats text in the named files for printing on a typesetter.  Nroff does the same, but produces output suitable for typewriter-like
       devices.

       If no file argument is present, the standard input is read.  An argument consisting of a single minus (-) is taken to be a file name corre-
       sponding to the standard input.	The options are:

       -olist  Print  pages  in the comma-separated list of numbers and ranges.  A range N-M means N through M; initial -M means up to M; final N-
	       means from N to the end.

       -nN     Number first generated page N.

       -mname  Process the macro file /sys/lib/tmac/tmac.name before the input files.

       -raN    Set register a (one character name) to N.

       -i      Read standard input after the input files are exhausted.

       -q      Invoke the simultaneous input-output mode of the rd request.

       -N      Produce output suitable for typewriter-like devices.

   Typesetter devices (not -N) only
       -a      Send a printable textual approximation of the results to the standard output.

       -Tdest  Prepare output for typesetter dest:
	       -Tutf	(The default.) PostScript printers with preprocessing to handle Unicode characters encoded in UTF

	       -Tpost	Regular PostScript printers

	       -T202	Mergenthaler Linotron 202

       -Fdir  Take font information from directory dir.

   Typewriter (-N) output only
       -sN     Halt prior to every N pages (default N=1) to allow paper loading or changing.

       -Tname  Prepare output for specified terminal.  Known names include utf for the normal Plan 9 UTF encoding of the Unicode Standard  charac-
	       ter  set  (default),  37  for the Teletype model 37, lp (`line-printer') for any terminal without half-line capability, 450 for the
	       DASI-450 (Diablo Hyterm), and think (HP ThinkJet).

       -e      Produce equally-spaced words in adjusted lines, using full terminal resolution.

       -h      Use output tabs during horizontal spacing to speed output and reduce output character count.  Tab settings are assumed to be  every
	       8 nominal character widths.
