+ * Output Notes:
+ *
+ * DfaStates == number of dfa nodes in automaton (just a #define)
+ * DfaState == type large enough to index every node in automaton
+ * <256 unsigned char, <65536 unsigned short, etc.
+ *
+ * Thus, the elements in each of the automaton states (st%d) are type DfaState
+ * and are size appropriately, since they must be able to index the next
+ * automaton state.
+ *
+ * dfa[] == a linear array that points to all the automaton states (st%d)
+ * (dfa_base[] should be the same, but isn't right now)
+ *
+ * accepts[] == Taking a closer look at this one, it probably shouldn't be type
+ * DfaState because there is no real requirement that the number of
+ * accepts states is less than the number of dfa state. However, if
+ * the number of accept states was more than the number of DFA states
+ * then the lexical specification would be really ambiguous.
+ *
+ * Another note. Is that is should be possible to fold accepts[] and
+ * actions[] together. If this is done, I would suggest get rid of
+ * accept[] and make actions[] have an entry for each state (st%d) in
+ * the automaton.
+ *
+ * dfa_base[] == starting location for each lexical mode. This should be
+ * Dfastate type (but isn't right now), since it points to the states
+ * in the automaton.
+ *
+ * dfa_class_no[] == indicates the number of columns each lexical mode has.
+ *
+ * b_class_no[] == pointer to the start of the translation array used to
+ * convert from input character to character class. This could cause
+ * problems if there are more than 256 classes
+ *
+ * shift%d[] == the actual translation arrays that convert the input character
+ * into the character class. These will have to change if there are
+ * more than 256 character classes.
