-.SH DESCRIPTION
-If no output_file is supplied, output goes to stdout.

-There are no error messages.

-.I ansi2knr
-recognizes function definitions by seeing a non-keyword identifier at the left

-following line (ignoring possible intervening comments).  It will recognize a

-     - Some macros that tinker with the syntax of the function header.

-The --varargs switch is obsolete, and is recognized only for

- * ansi2knr recognizes function definitions by seeing a non-keyword

- * will not be considered a function definition unless identifier2 is

- *	identifier1(identifier2, <<arbitrary>>)
- * will not be considered a function definition.
- * ansi2knr will recognize a multi-line header provided that no intervening

-	- the check for \ + newline in scanstring was unnecessary.
-
-	2000-03-05  Paul Eggert  <eggert@twinsun.com>
-
-	Add support for concatenated string literals.
-	* ansi2knr.c (concatlits): New decl.
-	(main): Invoke concatlits to concatenate string literals.
-	(scanstring): Handle backslash-newline correctly.  Work with
-	character constants.  Fix bug when scanning backwards through
-	backslash-quote.  Check for unterminated strings.
-	(convert1): Parse character constants, too.
-	(appendline, concatlits): New functions.
-	* ansi2knr.1: Document this.
-
-	lpd 1999-08-17 added code to allow preprocessor directives
-		wherever comments are allowed
-	lpd 1999-04-12 added minor fixes from Pavel Roskin
-		<pavel_roskin@geocities.com> for clean compilation with
-		gcc -W -Wall
-	lpd 1999-03-22 added hack to recognize lines consisting of
-		identifier1(identifier2, xxx) as *not* being procedures
-	lpd 1999-02-03 made indentation of preprocessor commands consistent
-	lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
-		endless loop; quoted strings within an argument list
-		confused the parser
-	lpd 1999-01-24 added a check for write errors on the output,
-		suggested by Jim Meyering <meyering@ascend.com>
-	lpd 1998-11-09 added further hack to recognize identifier(void)
-		as being a procedure
-	lpd 1998-10-23 added hack to recognize lines consisting of
-		identifier1(identifier2) as *not* being procedures
-	lpd 1997-12-08 made input_file optional; only closes input and/or
-		output file if not stdin or stdout respectively; prints
-		usage message on stderr rather than stdout; adds
-		--filename switch (changes suggested by
-		<ceder@lysator.liu.se>)
-	lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
-		compilers that don't understand void, as suggested by
-		Tom Lane
-	lpd 1996-01-15 changed to require that the first non-comment token
-		on the line following a function header be a left brace,
-		to reduce sensitivity to macros, as suggested by Tom Lane
-		<tgl@sss.pgh.pa.us>
-	lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
-		undefined preprocessor symbols as 0; changed all #ifdefs
-		for configuration symbols to #ifs
-	lpd 1995-04-05 changed copyright notice to make it clear that
-		including ansi2knr in a program does not bring the entire
-		program under the GPL
-	lpd 1994-12-18 added conditionals for systems where ctype macros

-	lpd 1994-10-10 removed CONFIG_BROKETS conditional
-	lpd 1994-07-16 added some conditionals to help GNU `configure',

 CHANGE LOG for Independent JPEG Group's JPEG software
 
 
+Version 9  13-Jan-2013
+----------------------
+
+Add cjpeg -rgb1 option to create an RGB JPEG file, and insert
+a simple reversible color transform into the processing which
+significantly improves the compression.
+The recommended command for lossless coding of RGB images is now
+cjpeg -rgb1 -block 1 -arithmetic.
+As said, this option improves the compression significantly, but
+the files are not compatible with JPEG decoders prior to IJG v9
+due to the included color transform.
+The used color transform and marker signaling is compatible with
+other JPEG standards (e.g., JPEG-LS part 2).
+
+Remove the automatic de-ANSI-fication support (Automake 1.12).
+Thank also to Nitin A Kamble for suggestion.
+
+Add remark for jpeg_mem_dest() in jdatadst.c.
+Thank to Elie-Gregoire Khoury for the hint.
+
+Support files with invalid component identifiers (created
+by Adobe PDF).  Thank to Robin Watts for the suggestion.
+
+Adapt full buffer case in jcmainct.c for use with scaled DCT.
+Thank to Sergii Biloshytskyi for the suggestion.
+
+Add type identifier for declaration of noreturn functions.
+Thank to Brett L. Moore for the suggestion.
+
+Correct argument type in format string, avoid compiler warnings.
+Thank to Vincent Torri for hint.
+
+Add missing #include directives in configuration checks, avoid
+configuration errors.  Thank to John Spencer for the hint.
+
+
+Version 8d  15-Jan-2012
+-----------------------
+
+Add cjpeg -rgb option to create RGB JPEG files.
+Using this switch suppresses the conversion from RGB
+colorspace input to the default YCbCr JPEG colorspace.
+This feature allows true lossless JPEG coding of RGB color images.
+The recommended command for this purpose is currently
+cjpeg -rgb -block 1 -arithmetic.
+SmartScale capable decoder (introduced with IJG JPEG 8) required.
+Thank to Michael Koch for the initial suggestion.
+
+Add option to disable the region adjustment in the transupp crop code.
+Thank to Jeffrey Friedl for the suggestion.
+
+Thank to Richard Jones and Edd Dawson for various minor corrections.
+
+Thank to Akim Demaille for configure.ac cleanup.
+
+
+Version 8c  16-Jan-2011
+-----------------------
+
+Add option to compression library and cjpeg (-block N) to use
+different DCT block size.
+All N from 1 to 16 are possible.  Default is 8 (baseline format).
+Larger values produce higher compression,
+smaller values produce higher quality.
+SmartScale capable decoder (introduced with IJG JPEG 8) required.
+
+
+Version 8b  16-May-2010
+-----------------------
+
+Repair problem in new memory source manager with corrupt JPEG data.
+Thank to Ted Campbell and Samuel Chun for the report.
+
+Repair problem in Makefile.am test target.
+Thank to anonymous user for the report.
+
+Support MinGW installation with automatic configure.
+Thank to Volker Grabsch for the suggestion.
+
+
+Version 8a  28-Feb-2010
+-----------------------
+
+Writing tables-only datastreams via jpeg_write_tables works again.
+
+Support 32-bit BMPs (RGB image with Alpha channel) for read in cjpeg.
+Thank to Brett Blackham for the suggestion.
+
+Improve accuracy in floating point IDCT calculation.
+Thank to Robert Hooke for the hint.

+The IJG code also defines typedef boolean, but we make it an "enum" by default.
 This doesn't affect the IJG programs because we don't import those Windows
 include files.  But if you use the JPEG library in your own program, and some
 of your program's files import one definition of boolean while some import the
 other, you can get all sorts of mysterious problems.  A good preventive step
 is to make the IJG library use "unsigned char" for boolean.  To do that,
 add something like this to your jconfig.h file:

 Switches for advanced users:
 
+	-arithmetic	Use arithmetic coding.  CAUTION: arithmetic coded JPEG
+			is not yet widely implemented, so many decoders will
+			be unable to view an arithmetic coded JPEG file at
+			all.
+
+	-block N	Set DCT block size.  All N from 1 to 16 are possible.
+			Default is 8 (baseline format).
+			Larger values produce higher compression,
+			smaller values produce higher quality
+			(exact DCT stage possible with 1 or 2; with the
+			default quality of 75 and default Luminance qtable
+			the DCT+Quantization stage is lossless for N=1).
+			CAUTION: An implementation of the JPEG SmartScale
+			extension is required for this feature.  SmartScale
+			enabled JPEG is not yet widely implemented, so many
+			decoders will be unable to view a SmartScale extended
+			JPEG file at all.
+
+	-rgb1		Create RGB JPEG file with reversible color transform.
+			Works like the -rgb switch (see above) and inserts a
+			simple reversible color transform into the processing
+			which significantly improves the compression.
+			Use this switch in combination with the -block N
+			switch (see above) for lossless JPEG coding.
+			CAUTION: A decoder with inverse color transform
+			support is required for this feature.  Reversible
+			color transform support is not yet widely implemented,
+			so many decoders will be unable to view a reversible
+			color transformed JPEG file at all.

 	-dct int	Use integer DCT method (default).
 	-dct fast	Use fast integer DCT (less accurate).
 	-dct float	Use floating-point DCT method.

 	-optimize	Perform optimization of entropy encoding parameters.
 	-progressive	Create progressive JPEG file.
+	-arithmetic	Use arithmetic coding.
 	-restart N	Emit a JPEG restart marker every N MCU rows, or every

 See the previous discussion of cjpeg for more details about these switches.
 If you specify none of these switches, you get a plain baseline-JPEG output
