5/// # Application ID (4 Bytes)
6///
7///  The 4-byte big-endian integer at offset 68 is an "Application ID" that can
8/// be set by the PRAGMA application_id command in order to identify the
9/// database as belonging to or associated with a particular application. The
10/// application ID is intended for database files used as an application
11/// file-format. The application ID can be used by utilities such as file(1) to
12/// determine the specific file type rather than just reporting
13/// "Sqlite3 Database". A list of assigned application IDs can be seen by
14/// consulting the magic.txt file in the Sqlite source repository.
