+**    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.
+**    ssiexprparserTOKENTYPE     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 ssiexprparserTOKENTYPE.  The entry in the union
+**                       for base tokens is called "yy0".
+**    YYSTACKDEPTH       is the maximum depth of the parser's stack.
+**    ssiexprparserARG_SDECL     A static variable declaration for the %extra_argument
+**    ssiexprparserARG_PDECL     A parameter declaration for the %extra_argument
+**    ssiexprparserARG_STORE     Code to store %extra_argument into yypParser
+**    ssiexprparserARG_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 that 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.
+**
+**   YYNSTATE <= N < YYNSTATE+YYNRULE   Reduce by rule N-YYNSTATE.

+**                                      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.
