PRG2LOUT(1)		    General Commands Manual		   PRG2LOUT(1)

       prg2lout	- convert computer program text	into Lout

       prg2lout	-l language [ options ]	files...

       Reformat	 computer  program text	for input to the Lout document format-
       ting system, taking care	of comments, character	strings,  tab  charac-
       ters, etc.

       prg2lout	reads the named	program	source files and produces output suit-
       able for	input to lout -s.  Thus,

	      prg2lout -l C foo.c | lout -s | lpr

       will print the C	program	foo.c on a PostScript printer.	Each file will
       start on	a new page, preceded by	its name in bold.

	      (Compulsory.)   Files are	written	in this	programmming language.
	      Run prg2lout -u to see the list of languages available.

	      Use a fixed width	font (the default for C).

	      Use a varying-width italic font with  non-italic	bold  keywords
	      (the default for Eiffel).

	      Use  a  varying-width  italic font with mathematical symbols and
	      non-italic bold keywords.

       -n     Do not print the file name before	each source file.

       -f font
	      Select a font family.  The default is -fCourier for -pfixed, and
	      -fTimes for -pvarying and	-psymbol.

       -s size
	      Select a Lout font size.	The default is -s9p (meaning 9 points)
	      for -pfixed, and -s10p for -pvarying and -psymbol.   These  work
	      well with	80-character-wide programs.

       -v vsize
	      Select  a	 Lout vertical inter-line gap.	The default is -v1.1fx
	      meaning 1.1 times	the font size measured from baseline to	 base-

       -b num Select  a	blank line scale factor.  The default is -b1.0 meaning
	      no scaling.  A good alternative is 0.6.

       -t num Set the tab interval to num characters (default is -t8).

       -T width
	      Without this option, prg2lout simulates tabs with	spaces.	  With
	      this option, prg2lout simulates tabs with	Lout tabulation	opera-
	      tors; width is the width of one tab interval in the final	print,
	      measured in Lout units.  This guarantees alignment of characters
	      following	tabs even with varying-width fonts, provided width  is
	      sufficiently  large.  For	example, -T0.5i	produces half-inch tab

       -L number
	      Attach line numbers to the program text, beginning  with	number
	      or  1 if number is not given.  You may need to give the 1	anyway
	      to prevent .I prg2lout from taking a following file  name	 as  a

       -N     Do not print line	numbers	on blank lines.

       -M     Like -N but do not assign	line numbers to	blank lines.

       -S filename
	      Use  filename  as	 the  setup file instead of the	system default
	      setup file.  The setup file determines the value of all  format-
	      ting options not given to	prg2lout as command line arguments.

       -u     Print  usage  information	 on  stderr,  including	available lan-
	      guages, and exit.

       -V     Print version information	on stderr and exit.

   Raw Mode
       There is	a "raw mode" usage of prg2lout invoked by a -r flag  (must  be
       the first argument).  This converts one program file into Lout-readable
       source without any heading or trailing information.  Synopsis:

	      prg2lout -r -i infile -o out -e err -t num -T width

       Users should never need this mode; it  is  invoked  automatically  from
       within  Lout  by	 symbols supplied with the standard configuration (see

       lout(1),	lpr(1),	ghostview(1).

       System",	Chapter	11.
