-/* The parser tables consist of these tables.
-
- YYTRANSLATE = vector mapping yylex's token numbers into bison's
- token numbers.
-
- YYTNAME = vector of string-names indexed by bison token number.
-
- YYTOKNUM = vector of yylex token numbers corresponding to entries
- in YYTNAME.
-
- YYRLINE = vector of line-numbers of all rules. For yydebug
- printouts.
-
- YYRHS = vector of items of all rules. This is exactly what RITEMS
- contains. For yydebug and for semantic parser.
-
- YYPRHS[R] = index in YYRHS of first item for rule R.
-
- YYR1[R] = symbol number of symbol that rule R derives.
-
- YYR2[R] = number of symbols composing right hand side of rule R.
-
- YYSTOS[S] = the symbol number of the symbol that leads to state S.
-
- YYDEFACT[S] = default rule to reduce with in state s, when YYTABLE
- doesn't specify something else to do. Zero means the default is an
- error.
-
- YYDEFGOTO[I] = default state to go to after a reduction of a rule
- that generates variable NTOKENS + I, except when YYTABLE specifies
- something else to do.
-
- YYPACT[S] = index in YYTABLE of the portion describing state S.
- The lookahead token's type is used to index that portion to find
- out what to do.
-
- If the value in YYTABLE is positive, we shift the token and go to
- that state.
-
- If the value is negative, it is minus a rule number to reduce by.
-
- If the value is zero, the default action from YYDEFACT[S] is used.
-
- YYPGOTO[I] = the index in YYTABLE of the portion describing what to
- do after reducing a rule that derives variable I + NTOKENS. This
- portion is indexed by the parser state number, S, as of before the
- text for this nonterminal was read. The value from YYTABLE is the
- state to go to if the corresponding value in YYCHECK is S.
-
- YYTABLE = a vector filled with portions for different uses, found
- via YYPACT and YYPGOTO.
-
- YYCHECK = a vector indexed in parallel with YYTABLE. It indicates,
- in a roundabout way, the bounds of the portion you are trying to
- examine.
-
- Suppose that the portion of YYTABLE starts at index P and the index
- to be examined within the portion is I. Then if YYCHECK[P+I] != I,
- I is outside the bounds of what is actually allocated, and the
- default (from YYDEFACT or YYDEFGOTO) should be used. Otherwise,
- YYTABLE[P+I] should be used.
-
- YYFINAL = the state number of the termination state. YYFLAG = most
- negative short int. Used to flag ?? */
