 /*
 ** Performance test for SQLite.
 **
 ** This program reads ASCII text from a file named on the command-line.
 ** It converts each SQL statement into UTF16 and submits it to SQLite
 ** for evaluation.  A new UTF16 database is created at the beginning of
 ** the program.  All statements are timed using the high-resolution timer
 ** built into Intel-class processors.
 **
 ** To compile this program, first compile the SQLite library separately
