** 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 generated parser

/* The next sections is a series of control #defines.
** 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.
** configparserTOKENTYPE 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 configparserTOKENTYPE. 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()
** configparserARG_SDECL A static variable declaration for the %extra_argument
** configparserARG_PDECL A parameter declaration for the %extra_argument
** configparserARG_PARAM Code to pass %extra_argument as a subroutine parameter
** configparserARG_STORE Code to store %extra_argument into yypParser
** configparserARG_FETCH Code to extract %extra_argument from yypParser
** configparserCTX_* As configparserARG_ except for %extra_context
** YYREALLOC Name of the realloc() function to use
** YYFREE Name of the free() function to use
** YYDYNSTACK True if stack space should be extended on heap
** 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
** YYNTOKEN Number of terminal symbols
** 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_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
** YY_MIN_REDUCE Minimum value for reduce actions
** YY_MAX_REDUCE Maximum value for reduce actions
** YY_MIN_DSTRCTR Minimum symbol value that has a destructor
** YY_MAX_DSTRCTR Maximum symbol value that has a destructor

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

**
** 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 == 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.
**
** N between YY_MIN_REDUCE Reduce by rule N-YY_MIN_REDUCE
** and YY_MAX_REDUCE
**
** 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
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
**
** 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.
**
** 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.
