+# This file contains suggested magic(5) text for the unix file(1)
+# utility for recognizing SQLite3 databases.
+#
+# When SQLite is used as an application file format, it is desirable to
+# 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. 
+#
+# 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 application_id pragma
+# is preferred.  The rule using offset 60 for Monotone is for historical
+# compatibility only.
