 ** A virtual filesystem (VFS) is an [sqlite3_vfs] object
 ** that SQLite uses to interact
 ** with the underlying operating system.  Most SQLite builds come with a
 ** single default VFS that is appropriate for the host computer.
 ** New VFSes can be registered and existing VFSes can be unregistered.
