+.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+The --varargs switch is obsolete, and is recognized only for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>.

+/*
+ * Usage:
+ ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
+ * --filename provides the file name for the #line directive in the output,
+ * overriding input_file (if present).
+ * If no input_file is supplied, input is read from stdin.
+ * If no output_file is supplied, output goes to stdout.
+ * There are no error messages.
+ *
+ * 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 and/or preprocessor directives), except that a line
+ * consisting of only
+ * identifier1(identifier2)
+ * will not be considered a function definition unless identifier2 is
+ * the word "void", and a line consisting of
+ * identifier1(identifier2, <<arbitrary>>)
+ * will not be considered a function definition.
+ * ansi2knr 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, comments, and preprocessor directives, except that
+ * the function name must be the first thing on the line. The following
+ * constructs will confuse it:
+ * - Any other construct that starts at the left margin and
+ * follows the above syntax (such as a macro or function call).
+ * - Some macros that tinker with the syntax of function headers.

+/*
+ * The original and principal author of ansi2knr is L. Peter Deutsch
+ * <ghost@aladdin.com>. Other authors are noted in the change history
+ * that follows (in reverse chronological order):
+
+ lpd 2000-04-12 backs out Eggert's changes because of bugs:
+ - concatlits didn't declare the type of its bufend argument;
+ - concatlits didn't't recognize when it was inside a comment;
+ - scanstring could scan backward past the beginning of the string; when
+ - 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
+ don't handle 8-bit characters properly, suggested by
+ Francois Pinard <pinard@iro.umontreal.ca>;
+ removed --varargs switch (this is now the default)
+ lpd 1994-10-10 removed CONFIG_BROKETS conditional
+ lpd 1994-07-16 added some conditionals to help GNU `configure',
+ suggested by Francois Pinard <pinard@iro.umontreal.ca>;
+ properly erase prototype args in function parameters,
+ contributed by Jim Avera <jima@netcom.com>;
+ correct error in writeblanks (it shouldn't erase EOLs)
