+ Berkeley Yacc owes much to the unflagging efforts of Keith Bostic.
+His badgering kept me working on it long after I was ready to quit.
+
+ Berkeley Yacc is based on the excellent algorithm for computing LALR(1)
+lookaheads developed by Tom Pennello and Frank DeRemer. The algorithm is
+described in their almost impenetrable article in TOPLAS 4,4.
+
+ Finally, much of the credit for the latest version must go to those
+who pointed out deficiencies of my earlier releases. Among the most
+prolific contributors were
+
+ Benson I. Margulies
+ Dave Gentzel
+ Antoine Verheijen
+ Peter S. Housel
+ Dale Smith
+ Ozan Yigit
+ John Campbell
+ Bill Sommerfeld
+ Paul Hilfinger
+ Gary Bridgewater
+ Dave Bakken
+ Dan Lanciani

+
+2010-06-07 Andres.Mejia
+
+ * main.c, output.c, reader.c, defs.h, skeleton.c:
+ Fix the output order of the generated parse code file. This allows for
+ the use of YYPARSE_PARAM, by having the output that checks for
+ YYPARSE_PARAM to be defined come after the C code block in the
+ definitions section of a yacc file.
+
+ Implement support for YYLEX_PARAM, similar to bison. This is useful for
+ support for building reentrant lexers with flex.
+
+ Fix a compatibility issue with bison's pure-parser option. Bison
+ defines yylex as sending at least one parameter, &yylval, as the first
+ parameter and doesn't seem to have an easy way to remove that parameter.
+ This on the other hand is rather convenient to support saving to yylval
+ from flex when building reentrant lexers and parsers.
+
+ Add support for the %parse-param and %lex-param directives used in
+ bison. This change bears some similarity to NetBSD's changes to byacc
+ at http://www.mail-archive.com/source-changes-full@netbsd.org/msg08143.html
+
+ Bison allows for POSIX yacc emulation via a yacc directive in the yacc
+ file, and also via a command line switch. Implement this feature as a
+ no-op for byacc, since byacc is designed to be POSIX yacc compatible
+ anyway. This allows for better compatibility with yacc sources written
+ for bison.

+
+ * reader.c: implement %pure-parser
+
+ * defs.h: modified skeleton to support %pure-parser feature
+
+ * main.c: add -P option to set %pure-parser
+
+ * output.c:
+ make -r and -p options work together. The -r option splits the generated
+ parser into code/table files; for this case we cannot use static data.
+ Also, we have to repeat the #define's used for prefix (-p) as well as the
+ redeclaration of yyparse(). Finally, allow any of the prefixed names to
+ be overridden, e.g., by passing a -D option to the compiler. Make that
+ a little more readable by putting a blank line before each chunk.
+
+ * defs.h: add definitions for %pure-parser
+
+ * skeleton.c:
+ put blank line before/after the redeclaration of yyparse()
+
+ * output.c: allow for other program redefining yylex()

+ reorder AC_INIT/AC_CONFIG_HEADER to make this "work" with autoconf 2.52
+
+ * makefile.in: modify so DESTDIR works
+

+
+ * aclocal.m4: add CF_CHECK_CACHE, needed for CF_PROG_EXT
+
+ * yacc.1: remove the discussion of TMPDIR since it is obsolete
+

+ The -r option has been implemented. The -r option tells Yacc to
+put the read-only tables in y.tab.c and the code and variables in
+y.code.c. Keith Bostic asked for this option so that :yyfix could be
+eliminated.
+
+ The -l and -t options have been implemented. The -l option tells
+Yacc not to include #line directives in the code it produces. The -t
+option causes debugging code to be included in the compiled parser.
+
+ The code for error recovery has been changed to implement the same
+algorithm as AT&T Yacc. There will still be differences in the way
+error recovery works because AT&T Yacc uses more default reductions
+than Berkeley Yacc.
+
+ The environment variable TMPDIR determines the directory where
+temporary files will be created. If TMPDIR is defined, temporary files
+will be created in the directory whose pathname is the value of TMPDIR.
+By default, temporary files are created in /tmp.
+
+ The keywords are now case-insensitive. For example, %nonassoc,
+%NONASSOC, %NonAssoc, and %nOnAsSoC are all equivalent.
+
+ Commas and semicolons that are not part of C code are treated as
+commentary.
+
+ Line-end comments, as in BCPL, are permitted. Line-end comments
+begin with // and end at the next end-of-line. Line-end comments are
+permitted in C code; they are converted to C comments on output.
+
+ The form of y.output files has been changed to look more like
+those produced by AT&T Yacc.
+
+ A new kind of declaration has been added. The form of the declaration
+is
+
+ %ident string
+
+where string is a sequence of characters begining with a double quote
+and ending with either a double quote or the next end-of-line, whichever
+comes first. The declaration will cause a #ident directive to be written
+near the start of the output file.
+
+ If a parser has been compiled with debugging code, that code can be
+enabled by setting an environment variable. If the environment variable
+YYDEBUG is set to 0, debugging output is suppressed. If it is set to 1,
+debugging output is written to standard output.

+Berkeley Yacc reflects its origins. The reason so many routines
+use exactly six register variables is that Berkeley Yacc was
+developed on a VAX using PCC. PCC placed at most six variables
+in registers. I went to considerable effort to find which six
+variables most belonged in registers. Changes in machines and
+compilers make that effort worthless, perhaps even harmful.
+
+The code contains many instances where address calculations are
+performed in particular ways to optimize the code for the VAX.

+The original README is below. I've updated this version of Berkeley Yacc
+to make it ANSI C compliant - Thomas Dickey
+
+-------------------------------------------------------------------------------
+ Berkeley Yacc is an LALR(1) parser generator. Berkeley Yacc has been made
+as compatible as possible with AT&T Yacc. Berkeley Yacc can accept any input
+specification that conforms to the AT&T Yacc documentation. Specifications
+that take advantage of undocumented features of AT&T Yacc will probably be
+rejected.
+
+ Berkeley Yacc is distributed with no warranty whatever. The code is certain
+to contain errors. Neither the author nor any contributor takes responsibility
+for any consequences of its use.
+
+ Berkeley Yacc is in the public domain. The data structures and algorithms
+used in Berkeley Yacc are all either taken from documents available to the
+general public or are inventions of the author. Anyone may freely distribute
+source or binary forms of Berkeley Yacc whether unchanged or modified.
+Distributers may charge whatever fees they can obtain for Berkeley Yacc.
+Programs generated by Berkeley Yacc may be distributed freely.
+
+ Please report bugs to
+
+ robert.corbett@eng.Sun.COM
+
+Include a small example if possible. Please include the banner string from
+skeleton.c with the bug report. Do not expect rapid responses.

+Berkeley Yacc (byacc) is a LALR(1) parser generator. Berkeley Yacc
+has been made as compatible as possible with AT&T Yacc. Berkeley
+Yacc can accept any input specification that conforms to the AT&T
+Yacc documentation.
+
+Some programs depend on a byacc (instead of bison).
