** 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.

**    BusmasterParserTOKENTYPE     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 BusmasterParserTOKENTYPE.  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()

**    BusmasterParserARG_SDECL     A static variable declaration for the %extra_argument

**    BusmasterParserARG_PDECL     A parameter declaration for the %extra_argument

**    BusmasterParserARG_PARAM     Code to pass %extra_argument as a subroutine parameter

**    BusmasterParserARG_STORE     Code to store %extra_argument into yypParser

**    BusmasterParserARG_FETCH     Code to extract %extra_argument from yypParser

**    BusmasterParserCTX_*         As BusmasterParserARG_ except for %extra_context

**    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

/* 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 == 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.
