The database engine that is inside this executable is provided by the good people of the SQLite project.
I have not written any part of it!
Nor have I modified it!
The SQLite project publishes a "C" header file and a "C" source file that can be embedded in to an application. These SQLite files provide that application with a database capability.
I regularly check the SQLite web site ( www.sqlite.org) for updates, and include them in to my executable.
All of the database functionality in my executable comes from the SQLite files.
I am most grateful to them!
Some people have provided "C" source files that extend the capabilities of the SQLite code. These are called extensions.
I have included some extensions in this executable.
For details about these extensions please refer to the SQLite web site.
I am also most grateful to the developers of these extensions.
