The SQLite version 3 back-end requires
	the SQLite version 3 shared library file. Its default file name is
	/usr/lib/libsqlite3.so.
Use
(asdf:operate 'asdf:load-op 'clsql-sqlite3)
to load the SQLite version 3 back-end. The database type for the SQLite version 3 back-end is :sqlite3.
filenameString representing the filename of the SQLite version 3 database file.
init-function
		 A function designator.
		 init-function takes a
		 single argument of type
		 sqlite3:sqlite3-db, a foreign pointer to
		 the C descriptor of the newly opened database.
		 init-function is called by
		 the back-end immediately after SQLite version 3
		 sqlite3_open library function,
		 and can be used to perform optional database
		 initializations by calling foreign functions in the
		 SQLite version 3 library.
		
		 An example of an initialization function which
		 defines a new collating sequence for text columns is
		 provided in
		 ./examples/sqlite3/init-func/.
		
            Passing filename a value of
            :memory: will create a database in
            physical memory instead of using a file on disk.
          
Some operations will be many times faster if database integrity checking is disabled by setting the SYNCHRONOUS flag to OFF (see the SQLITE manual for details).
The :owner keyword argument to the FDDL functions for listing and testing for database objects is ignored.
            The :column-list keyword argument to
            create-view
            is not supported by SQLite version 3.
