+*************************************************************************
+**
+** This is a utility program designed to aid running the SQLite library
+** against an external fuzzer, such as American Fuzzy Lop (AFL)
+** (http://lcamtuf.coredump.cx/afl/). Basically, this program reads
+** SQL text from standard input and passes it through to SQLite for evaluation,
+** just like the "sqlite3" command-line shell. Differences from the
+** command-line shell:
+**
+** (1) The complex "dot-command" extensions are omitted. This
+** prevents the fuzzer from discovering that it can run things
+** like ".shell rm -rf ~"
+**
+** (2) The database is opened with the SQLITE_OPEN_MEMORY flag so that
+** no disk I/O from the database is permitted. The ATTACH command
+** with a filename still uses an in-memory database.
+**
+** (3) The main in-memory database can be initialized from a template
+** disk database so that the fuzzer starts with a database containing
+** content.
+**
+** (4) The eval() SQL function is added, allowing the fuzzer to do
+** interesting recursive operations.
