/***** This file contains automatically generated code ******

** The code in this file implements a function that determines whether
** or not a given identifier is really an SQL keyword. The same thing
** might be implemented more directly using a hand-written hash table.
** But by using this automatically generated code, the size of the code
** is substantially reduced. This is important for embedded applications
