 /* Driver template for the LEMON parser generator.
 ** The author disclaims copyright to this source code.
 **
 ** This version of "lempar.c" is modified, slightly, for use by SQLite.
 ** The only modifications are the addition of a couple of NEVER()
 ** macros to disable tests that are needed in the case of a general
 ** LALR(1) grammar but which are always false in the
 ** specific grammar used by SQLite.
