/* Parser accelerator module */
-#include <stdio.h>
+/* The parser as originally conceived had disappointing performance.
+ This module does some precomputation that speeds up the selection
+ of a DFA based upon a token, turning a search through an array
+ into a simple indexing operation. The parser now cannot work
+ without the accelerators installed. Note that the accelerators
+ are installed dynamically when the parser is initialized, they
+ are not part of the static data structure written on graminit.[ch]
+ by the parser generator. */
