DESCRIPTION
       Converts the specified file(s) containing C/C++ code to Postscript out‐
       put conforming to the Adobe Structuring Conventions.

       If no input file is specified then input is accepted from stdin.	 Post‐
       script output is directed to stdout unless you specify an output	 file.
       The actual output page may be out with one, two or four columns.

       Supported paper types are A4 and Letter.

       Tabs  in the input stream are expanded (by default) by blank characters
       to the closest modulo 8 position. You can  specify  your	 own  constant
       number of blanks different from 8 for a tab to expand.

       A formfeed (^L) character makes the converter move to the next column.

       By  default,  C/C++  constructs are highlighted with following standard
       fonts presented on every Postscript printer:

	    Preprocessor directives  Courier-BoldOblique

	    Comments		     Helvetica-Oblique

	    Strings		     Courier-Oblique

	    Keywords		     Courier-Bold

	    Line numbers	     Times-Roman

	    Types		     Courier-Bold

	    Function identificators  Bookman-LightItalic

       The rest is printed with Courier (default  font).  If  highlighting  is
       disabled	 only the default font is used to print the read code (but not
       line numbers).

       Comments may be printed dimmed to a configurable degree in a  way  that
       allows  reader  to concentrate mainly on the source itself referring to
       comments only when needed.

       c2ps has basic preprocessor capabilities. You may define/undefine  pre‐
       processor  variables  in	 the  command  line.   c2ps will neglect those
       pieces of code that are cut out by the preprocessor given a set of men‐
       tioned variables.

       By  default, on each column c2ps draws an alphabetic index of all func‐
       tion id definitions with locations, scanned from the beginning  of  the
       file being printed.  As the number of these id's grows the font used to
       print the index may  get	 smaller  in  order  to	 accommodate  all  the
       entries.

       Occasionally, function index is drawn upon already printed source code.
       To cope with this you can either cancel the index option or use smaller
       fonts.

       All  the	 read  symbols	with  codes  128..255 (0x80..0xff) are printed
       escaped so that c2ps output is all clean 7-bit ascii and	 can  be  sent
       over the Internet without uuencoding.

       You  can	 easily	 print source including fragments in Cyrillic, Hebrew,
       Arabic etc.  which may be found in string  and/or  comments  if	you're
       printing	 C/C++ code and anywhere otherwise. You just need a postscript
       font with encoding corresponding to the one that is used in  the	 above
       fragments.  If there's no suitable built-in font in your PS printer you
       will have to prepend one to c2ps output.

       If the symbols from the both halves of the code table  are  implemented
       in  your	 PS  font,  you may simply use it to print any constructs that
       include 8-bit text (don't forget to disable ISO Latin 1	font  reencod‐
       ing).  Otherwise, with only upper half symbols (with codes > 127(0x7f))
       implemented, there is an option to set a	 font  to  print  specifically
       these symbols leaving the rest to be printed by either default or newly
       set fonts.

       Also, as much as we know there exists a version	of  c2ps  modified  to
       support	Chinese	 (Hanja) and Korean (Hangul). An address of the imple‐
       mentor is on the c2ps web page.

       This is a manual page for c2ps ver4.0

OPTIONS
       -? -h  Print usage message.

       -1     Specify single column per page output - default (portrait).

       -2     Specify two columns per page output (1/2 size, landscape).

       -4     Specifiy four columns per page output (1/4 size, portrait).

       -a     Disable adjusted multiple lines comments printing.

       -b     Disable drawing a box containing alphabetic index	 of  functions
	      scanned from the beginning of the file.

       -c     Disable C/C++ construct highlighting.

       -e     Disable  printing	 entry/exit  function  name  in	 the  column's
	      header.

       -i     Disable ISO 8859-1 (ISO Latin 1) character encoding.

       -k     Use standard set of keywords rather than extended one.

       -m     When printing a file use the date of printing instead of	file's
	      last modification date.

       -n     Disable line numbering.

       -r     Draw a frame round each column.

       -u     Disable drawing header at the top of each column.

       -v     Print current version.

       -w     Disable  wrapping	 too  wide  lines onto following lines.	 Note,
	      that when wrapping is enabled the maximum number	of  characters
	      in  line	printed	 with any font is the number of the same point
	      size Courier characters that may appear in single	 line  without
	      crossing column's border.

       -x     Automatically  toggle C/C++ highlight flag for each file accord‐
	      ing to its extension.  ( Applicable extensions  include	.c  .h
	      .cc .hh .cpp .hpp )

       -F defaultfont
	      Use defaultfont as default font.

       -C commentfont
	       Use commentfont to print comments.

       -K keywordfont
	      Use keywordfont to print keywords.

       -N lnumberfont
	      Use lnumberfont to print line numbers.

       -P preprocfont
	      Use preprocfont to print preprocessor directives.

       -S stringfont
	      Use stringfont to print strings.

       -T typefont
	      Use typefont to print types.

       -U functionfont
	      Use functionfont to print function identificators being defined.

       -X nonlatinfont
	      Use  nonlatinfont	 to  print all symbols with codes > 127(0x7f).
	      ISO Latin 1 encoding is automatically cancelled.

       -d dim Print comments dimmed with the coefficient dim.
	       ( black: 0.0 <= dim <= 1.0 :white ). Default is 0.75.   So  you
	      can actually get rid of the comments in your printout by setting
	      dim coef. to 1.0

       -f pointsize
	      Use pointsize -scaled fonts ( 10 - default ).

       -l lines
	      Make converter start a  new  column  after  each	set  of	 lines
	      printed lines. You may want to use the resulted at the bottom of
	      the column white space for notes if the space on	the  right  is
	      not sufficient.

       -p paper
	      Paper type specification ( A4 - default, Letter ).

       -s points
	      Leave points * 1/72 inch space between lines ( 0.0 - default ).

       -t tabsize
	      Expand  each read tab with blanks to a next modulo tabsize posi‐
	      tion ( 8 - default ).

       -_  fun_highlight
	      Specify function id highlighting type ( none, box,  underline  -
	      default ).

       -DPREPROC_VAR

       -UPREPROC_VAR
	      You  may define or undefine preprocessor variables in a standard
	      compiler option fashion.

	      Below:
	       +/-: printed/not printed by c2ps
	       column 1: for variable X not mentioned in command line
	       column 2: for variable X defined
	       column 3: for variable X undefined

		 1  2  3
		 +  -  -    #ifdef X
		 +  +  -      C/C++ code (+ preprocessor directives)
		 +  -  -    #else
		 +  -  +      C/C++ code (+ preprocessor directives)
		 +  -  -    #endif

	      Similarly for #ifndef, just switch columns 2 and 3.

EXAMPLES
       Multiple files
	  c2ps *.c *.h | lpr

       Ordinary text
	  c2ps note.txt -c -n -u > note.ps

       ISO Latin 1 font reencoding by default
	  c2ps -2 -c -n -F Times-Roman german.txt > german.ps

       A different look
	  c2ps -F Times-Roman -C Palatino-BoldItalic -K Times-Bold
	       -N Helvetica -P Helvetica-Bold -S Times-Italic
	       -T Times-BoldItalic -_ box -w sample.c > sample.ps

       An option set looking better on low resolution printers
	  c2ps -d 0 -C Palatino-Italic main.cc > main.ps

       Partial preprocessing, selective printing
	  c2ps -DDEBUG -DSUN_SPECIFIC -UPRINT *.cc | lpr

       Temporarily commented out code (still looks like a part of the code but
       a little bit dimmed)
	  c2ps -C Courier -d 0.5 temp.c -o temp.ps

       Getting rid of comments
	  c2ps -_ box -d 1 main.cc | lpr

       Printing 8-bit text (e.g. Cyrillic, koi-8 encoding)
	  c2ps -i -C Antique-Italic -S Antique koi8.cc > tmp
	  cat Antique-Italic.pfa Antique.pfa tmp | lpr

	  c2ps -i -c -n -F Antique koi8.cc > tmp
	  cat Antique.pfa tmp | lpr

	  c2ps -X Cyrillic-Italic-koi8 koi8.cc > tmp
	  cat Cyrillic-Italic-koi8.ps tmp | lpr
