NAME

       prg2lout - convert computer program text into Lout

SYNOPSIS

       prg2lout -l language [ options ] files...

DESCRIPTION

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

       prg2lout reads the named program source files and produces output suitable 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.

OPTIONS

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

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

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

       -psymbol
	      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 baseline.

       -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 operators;
	      width is the width of one tab interval in the final print, measured in Lout units.  This guarantees alignment of characters  follow-
	      ing tabs even with varying-width fonts, provided width is sufficiently large.  For example, -T0.5i produces half-inch tab intervals.

       -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 number.

       -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	formatting
	      options not given to prg2lout as command line arguments.

       -u     Print usage information on stderr, including available languages, 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-read-
       able 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
       reference).
