# have file(1) recognize the database file as being with the specific
# application.  You can set the application_id for a database file
# using:
#
#     PRAGMA application_id = INTEGER;
#
# INTEGER can be any signed 32-bit integer.  That integer is written as
# a 4-byte big-endian integer into offset 68 of the database header.  In
# the tests below, this integer is sometimes rendered as a string.  For
# example, instead of "belong =1598444364" we write "string =_FSL" and
# instead of "belong =1598903374" we write "string =_MTN".
#
# The Monotone application used "PRAGMA user_version=1598903374;" to set
# its identifier long before "PRAGMA application_id" became available.
# The user_version is very similar to application_id except that it is
# stored at offset 68 instead of offset 60.  The user of 
# "PRAGMA application_id" is preferred now.  The rules using offset 60
# for Monotone are for historical compatibility only.
