-**    YYCODETYPE         is the data type used for storing terminal
-**                       and nonterminal numbers.  "unsigned char" is
-**                       used if there are fewer than 250 terminals
-**                       and nonterminals.  "int" is used otherwise.
-**    YYNOCODE           is a number of type YYCODETYPE which corresponds
-**                       to no legal terminal or nonterminal number.  This
-**                       number is used to fill in empty slots of the hash 
-**                       table.
-**    YYFALLBACK         If defined, this indicates that one or more tokens
-**                       have fall-back values which should be used if the
-**                       original value of the token will not parse.
-**    YYACTIONTYPE       is the data type used for storing terminal
-**                       and nonterminal numbers.  "unsigned char" is
-**                       used if there are fewer than 250 rules and
-**                       states combined.  "int" is used otherwise.
-**    ParseTOKENTYPE     is the data type used for minor tokens given 
-**                       directly to the parser from the tokenizer.
-**    YYMINORTYPE        is the data type used for all minor tokens.
-**                       This is typically a union of many types, one of
-**                       which is ParseTOKENTYPE.  The entry in the union
-**                       for base tokens is called "yy0".
-**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
-**                       zero the stack is dynamically sized using realloc()
-**    ParseARG_SDECL     A static variable declaration for the %extra_argument
-**    ParseARG_PDECL     A parameter declaration for the %extra_argument
-**    ParseARG_STORE     Code to store %extra_argument into yypParser
-**    ParseARG_FETCH     Code to extract %extra_argument from yypParser
-**    YYNSTATE           the combined number of states.
-**    YYNRULE            the number of rules in the grammar
-**    YYERRORSYMBOL      is the code number of the error symbol.  If not
-**                       defined, then do no error processing.

-/* Next are the tables used to determine what action to take based on the

-** action integer.  
-**
-** Suppose the action integer is N.  Then the action is determined as
-** follows
-**
-**   0 <= N < YYNSTATE                  Shift N.  That is, push the lookahead
-**                                      token onto the stack and goto state N.

-**                                      slots in the yy_action[] table.
-**
-** The action table is constructed as a single large table named yy_action[].
-** Given state S and lookahead X, the action is computed as
-**
-**      yy_action[ yy_shift_ofst[S] + X ]
-**
-** If the index value yy_shift_ofst[S]+X is out of range or if the value
-** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
-** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
-** and that yy_default[S] should be used instead.  
-**
-** The formula above is for computing the action when the lookahead is
-** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
-** a reduce action) then the yy_reduce_ofst[] array is used in place of
-** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
-** YY_SHIFT_USE_DFLT.
-**
-** The following are the tables generated in this section:
-**
-**  yy_action[]        A single table containing all actions.
-**  yy_lookahead[]     A table containing the lookahead for each entry in
-**                     yy_action.  Used to detect hash collisions.
-**  yy_shift_ofst[]    For each state, the offset into yy_action for
-**                     shifting terminals.
-**  yy_reduce_ofst[]   For each state, the offset into yy_action for
-**                     shifting non-terminals after a reduce.
-**  yy_default[]       Default action for each state.
