-     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.
