*************************************************************************
**
** This is a utility program designed to aid running regressions tests
** on SQLite library using data from an external fuzzer, such as American
** Fuzzy Lop (AFL) (http://lcamtuf.coredump.cx/afl/).
**
** This program reads content from an SQLite database file with the following
** schema:
**
** CREATE TABLE db(
** dbid INTEGER PRIMARY KEY, -- database id
** dbcontent BLOB -- database disk file image
** );
** CREATE TABLE xsql(
** sqlid INTEGER PRIMARY KEY, -- SQL script id
** sqltext TEXT -- Text of SQL statements to run
** );
**
** For each database file in the DB table, the SQL text in the XSQL table
** is run against that database. This program is looking for crashes,
** assertion faults, and/or memory leaks. No attempt is made to verify
** the output. The assumption is that either all of the database files
** or all of the SQL statements are malformed inputs, generated by a fuzzer,
** that need to be checked to make sure they do not present a security risk.
**
** This program also includes some command-line options to help with
** creation and maintenance of the source content database.
