-*************************************************************************
-**
-** This is a utility program designed to aid running regressions tests on
-** the 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
-** );
-** CREATE TABLE IF NOT EXISTS readme(
-** msg TEXT -- Human-readable description of this test collection
-** );
-**
-** For each database file in the DB table, the SQL text in the XSQL table
-** is run against that database. All README.MSG values are printed prior
-** to the start of the test (unless the --quiet option is used). If the
-** DB table is empty, then all entries in XSQL are run against an empty
-** in-memory 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. The command
-**
-** ./fuzzcheck database.db --load-sql FILE...
-**
-** Loads all FILE... arguments into the XSQL table. The --load-db option
-** works the same but loads the files into the DB table. The -m option can
-** be used to initialize the README table. The "database.db" file is created
-** if it does not previously exist. Example:
-**
-** ./fuzzcheck new.db --load-sql *.sql
-** ./fuzzcheck new.db --load-db *.db
-** ./fuzzcheck new.db -m 'New test cases'
-**
-** The three commands above will create the "new.db" file and initialize all
-** tables. Then do "./fuzzcheck new.db" to run the tests.
-**
-** DEBUGGING HINTS:
-**
-** If fuzzcheck does crash, it can be run in the debugger and the content
-** of the global variable g.zTextName[] will identify the specific XSQL and
-** DB values that were running when the crash occurred.
