** Driver template for the LEMON parser generator.
**
** The "lemon" program processes an LALR(1) input grammar file, then uses
** this template to construct a parser. The "lemon" program inserts text
** at each "%%" line. Also, any "P-a-r-s-e" identifer prefix (without the
** interstitial "-" characters) contained in this template is changed into
** the value of the %name directive from the grammar. Otherwise, the content
** of this template is copied straight through into the generate parser
** source file.
**
** The following is the concatenation of all %include directives from the
** input grammar file:

** various aspects of the generated parser.
** YYCODETYPE is the data type used to store the integer codes
** that represent terminal and non-terminal symbols.
** "unsigned char" is used if there are fewer than
** 256 symbols. Larger types otherwise.
** YYNOCODE is a number of type YYCODETYPE that is not used for
** any terminal or nonterminal symbol.
** YYFALLBACK If defined, this indicates that one or more tokens
** (also known as: "terminal symbols") have fall-back
** values which should be used if the original symbol
** would not parse. This permits keywords to sometimes
** be used as identifiers, for example.
** YYACTIONTYPE is the data type used for "action codes" - numbers
** that indicate what to do in response to the next
** token.
** ParseTOKENTYPE is the data type used for minor type for terminal
** symbols. Background: A "minor type" is a semantic
** value associated with a terminal or non-terminal
** symbols. For example, for an "ID" terminal symbol,
** the minor type might be the name of the identifier.
** Each non-terminal can have a different minor type.
** Terminal symbols all have the same minor type, though.
** This macros defines the minor type for terminal
** symbols.
** YYMINORTYPE is the data type used for all minor types.
** This is typically a union of many types, one of
** which is ParseTOKENTYPE. The entry in the union
** for terminal symbols 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
** YYERRORSYMBOL is the code number of the error symbol. If not
** defined, then do no error processing.
** YYNSTATE the combined number of states.
** YYNRULE the number of rules in the grammar
** YY_MAX_SHIFT Maximum value for shift actions
** YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
** YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
** YY_MIN_REDUCE Maximum value for reduce actions
** YY_ERROR_ACTION The yy_action[] code for syntax error
** YY_ACCEPT_ACTION The yy_action[] code for accept
** YY_NO_ACTION The yy_action[] code for no-op

/* Next are the tables used to determine what action to take based on the
** current state and lookahead token. These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N. Then the action is determined as
** follows
**
** 0 <= N <= YY_MAX_SHIFT Shift N. That is, push the lookahead
** token onto the stack and goto state N.
**
** N between YY_MIN_SHIFTREDUCE Shift to an arbitrary state then
** and YY_MAX_SHIFTREDUCE reduce by rule N-YY_MIN_SHIFTREDUCE.
**
** N between YY_MIN_REDUCE Reduce by rule N-YY_MIN_REDUCE
** and YY_MAX_REDUCE
**
** N == YY_ERROR_ACTION A syntax error has occurred.
**
** N == YY_ACCEPT_ACTION The parser accepts its input.
**
** N == YY_NO_ACTION No such action. Denotes unused
** 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 either:
**
** (A) N = yy_action[ yy_shift_ofst[S] + X ]
** (B) N = yy_default[S]
**
** The (A) formula is preferred. The B formula is used instead if:
** (1) The yy_shift_ofst[S]+X value is out of range, or
** (2) yy_lookahead[yy_shift_ofst[S]+X] is not equal to X, or
** (3) yy_shift_ofst[S] equal YY_SHIFT_USE_DFLT.
** (Implementation note: YY_SHIFT_USE_DFLT is chosen so that
** YY_SHIFT_USE_DFLT+X will be out of range for all possible lookaheads X.
** Hence only tests (1) and (2) need to be evaluated.)
**
** The formulas above are 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.
