88 # Version 1 used GDBM internally; its files cannot be distinguished
89 # from other GDBM files.

91 # Version 2 used this format:

94 # URL: https://en.wikipedia.org/wiki/SQLite
95 # Reference: https://www.sqlite.org/fileformat.html
96 # Update: Joerg Jenderek
97 # Version 3 of SQLite allows applications to embed their own "user version"
98 # number in the database at offset 60. Later, SQLite added an "application id"
99 # at offset 68 that is preferred over "user version" for indicating the
100 # associated application.
