! 31: * Usage:
! 32: ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
! 33: * --filename provides the file name for the #line directive in the output,
! 34: * overriding input_file (if present).
! 35: * If no input_file is supplied, input is read from stdin.
! 36: * If no output_file is supplied, output goes to stdout.
! 37: * There are no error messages.
! 38: *
! 39: * ansi2knr recognizes function definitions by seeing a non-keyword
! 40: * identifier at the left margin, followed by a left parenthesis,
! 41: * with a right parenthesis as the last character on the line,
! 42: * and with a left brace as the first token on the following line
! 43: * (ignoring possible intervening comments), except that a line
! 44: * consisting of only
! 45: * identifier1(identifier2)
! 46: * will not be considered a function definition unless identifier2 is
! 47: * the word "void", and a line consisting of
! 48: * identifier1(identifier2, <<arbitrary>>)
! 49: * will not be considered a function definition.
! 50: * ansi2knr will recognize a multi-line header provided
! 51: * that no intervening line ends with a left or right brace or a semicolon.
! 52: * These algorithms ignore whitespace and comments, except that
! 53: * the function name must be the first thing on the line.
! 54: * The following constructs will confuse it:
! 55: * - Any other construct that starts at the left margin and
! 56: * follows the above syntax (such as a macro or function call).
! 57: * - Some macros that tinker with the syntax of function headers.

! 61: * The original and principal author of ansi2knr is L. Peter Deutsch
! 62: * <ghost@aladdin.com>. Other authors are noted in the change history
! 63: * that follows (in reverse chronological order):
! 64: lpd 1999-04-12 added minor fixes from Pavel Roskin
! 65: <pavel_roskin@geocities.com> for clean compilation with
! 66: gcc -W -Wall
! 67: lpd 1999-03-22 added hack to recognize lines consisting of
! 68: identifier1(identifier2, xxx) as *not* being procedures
! 69: lpd 1999-02-03 made indentation of preprocessor commands consistent
! 70: lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
! 71: endless loop; quoted strings within an argument list
! 72: confused the parser
! 73: lpd 1999-01-24 added a check for write errors on the output,
! 74: suggested by Jim Meyering <meyering@ascend.com>
! 75: lpd 1998-11-09 added further hack to recognize identifier(void)
! 76: as being a procedure
! 77: lpd 1998-10-23 added hack to recognize lines consisting of
! 78: identifier1(identifier2) as *not* being procedures
! 79: lpd 1997-12-08 made input_file optional; only closes input and/or
! 80: output file if not stdin or stdout respectively; prints
! 81: usage message on stderr rather than stdout; adds
! 82: --filename switch (changes suggested by
! 83: <ceder@lysator.liu.se>)
! 84: lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
! 85: compilers that don't understand void, as suggested by
! 86: Tom Lane
! 87: lpd 1996-01-15 changed to require that the first non-comment token
! 88: on the line following a function header be a left brace,
! 89: to reduce sensitivity to macros, as suggested by Tom Lane
! 90: <tgl@sss.pgh.pa.us>
! 91: lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
! 92: undefined preprocessor symbols as 0; changed all #ifdefs
! 93: for configuration symbols to #ifs
! 94: lpd 1995-04-05 changed copyright notice to make it clear that
! 95: including ansi2knr in a program does not bring the entire
! 96: program under the GPL
! 97: lpd 1994-12-18 added conditionals for systems where ctype macros
! 98: don't handle 8-bit characters properly, suggested by
! 99: Francois Pinard <pinard@iro.umontreal.ca>;
! 100: removed --varargs switch (this is now the default)
! 101: lpd 1994-10-10 removed CONFIG_BROKETS conditional
! 102: lpd 1994-07-16 added some conditionals to help GNU `configure',
! 103: suggested by Francois Pinard <pinard@iro.umontreal.ca>;
! 104: properly erase prototype args in function parameters,
! 105: contributed by Jim Avera <jima@netcom.com>;
! 106: correct error in writeblanks (it shouldn't erase EOLs)
! 107: lpd 1989-xx-xx original version
