+/* 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.
+
+ YYFINAL = the state number of the termination state.
+
+ YYTABLE = a vector filled with portions for different uses, found
+ via YYPACT and YYPGOTO, described below.
+
+ YYLAST ( = high) the number of the last element of YYTABLE, i.e.,
+ sizeof (YYTABLE) - 1.
+
+ 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.
+
+ YYDEFACT[S] = default reduction number in state s. Performed 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 number, I, is used to index that portion of
+ YYTABLE to find out what action to perform.
+
+ If YYPACT[S] == YYPACT_NINF, if YYPACT[S] + I is outside the bounds
+ of YYTABLE (from 0 to YYLAST), or I is outside the bounds for portion
+ S (that is, YYCHECK[YYPACT[S] + I] != I), then the default action
+ (that is, YYDEFACT[S]) should be used instead of YYTABLE. Otherwise,
+ the value YYTABLE[YYPACT[S] + I] should be used even if
+ YYPACT[S] < 0.
+
+ 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 YYTABLE_NINF, it's a syntax error.
+
+ 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.
+
+ If YYPGOTO[I] + S is outside the bounds of YYTABLE (from 0 to YYLAST)
+ or if S is outside the bounds of the portion for I (that is,
+ YYCHECK[YYPGOTO[I] + S] != S), then the default state (that is,
+ YYDEFGOTO[I]) should be used instead of YYTABLE. Otherwise,
+ YYTABLE[YYPGOTO[I] + S] is the state to go to even if YYPGOTO[I] < 0.
+
+ When the above YYPACT, YYPGOTO, and YYCHECK tests determine that a
+ value from YYTABLE should be used, that value is never zero, so it is
+ useless to check for zero. When those tests indicate that the value
+ from YYDEFACT or YYDEFGOTO should be used instead, the value from
+ YYTABLE *might* be zero, which, as a consequence of the way in which
+ the tables are constructed, also happens to indicate that YYDEFACT or
+ YYDEFGOTO should be used. However, the YYTABLE value cannot be
+ trusted when the YYDEFACT or YYDEFGOTO value should be used. In
+ summary, forget about zero values in YYTABLE.
