+/*
+** Performance test for SQLite.
+**
+** This program reads ASCII text from a file named on the command-line
+** and submits that text  to SQLite for evaluation.  A new 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
+** will full optimizations.  For example:
+**
+**     gcc -c -O6 -DSQLITE_THREADSAFE=0 sqlite3.c
+**
+** Then link against this program.  But to do optimize this program
+** because that defeats the hi-res timer.
+**
+**     gcc speedtest8.c sqlite3.o -ldl -I../src
+**
+** Then run this program with a single argument which is the name of
+** a file containing SQL script that you want to test:
+**
+**     ./a.out test.db  test.sql
