-- Run this script through the sqlite3 command-line shell in order to generate
-- a database file containing lots of data for testing purposes.
--
-- This script assumes that the "bin2c" program is available on ones $PATH.
-- The "bin2c" program reads a binary file and outputs C-code that creates
-- an array of bytes holding the content of that file.
--
-- This script is designed to create many tables and views all having
-- 5 columns, "a" through "e", and with a variety of integers, short strings,
-- and NULL values.
