-.TH ANSI2KNR 1 "19 Jan 1996"
-.SH NAME
-ansi2knr \- convert ANSI C to Kernighan & Ritchie C
-.SH SYNOPSIS
-.I ansi2knr
-[--varargs] input_file [output_file]
-.SH DESCRIPTION
-If no output_file is supplied, output goes to stdout.
-.br
-There are no error messages.
-.sp
-.I ansi2knr
-recognizes function definitions by seeing a non-keyword identifier at the left
-margin, followed by a left parenthesis, with a right parenthesis as the last
-character on the line, and with a left brace as the first token on the
-following line (ignoring possible intervening comments).  It will recognize a
-multi-line header provided that no intervening line ends with a left or right
-brace or a semicolon.  These algorithms ignore whitespace and comments, except
-that the function name must be the first thing on the line.
-.sp
-The following constructs will confuse it:
-.br
-     - Any other construct that starts at the left margin and follows the
-above syntax (such as a macro or function call).
-.br
-     - Some macros that tinker with the syntax of the function header.
-.sp
-The --varargs switch is obsolete, and is recognized only for
-backwards compatibility.  The present version of
-.I ansi2knr
-will always attempt to convert a ... argument to va_alist and va_dcl.
-.SH AUTHOR
-L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
-continues to maintain the current version; most of the code in the current
-version is his work.  ansi2knr also includes contributions by Francois
-Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

 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.

+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:
-	/* Define "boolean" as unsigned char, not int, per Windows custom */
+	/* Define "boolean" as unsigned char, not enum, per Windows custom */
 	#ifndef __RPCNDR_H__	/* don't conflict if rpcndr.h already read */
