#
# Version 1 used GDBM internally; its files cannot be distinguished
# from other GDBM files.
#
# Version 2 used this format:
0	string	**\ This\ file\ contains\ an\ SQLite  SQLite 2.x database

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