+# Organization of tests in this file:
+#
+# vtab1-1.*: Error conditions and other issues surrounding creation/connection
+#            of a virtual module.
+# vtab1-2.*: Test sqlite3_declare_vtab() and the xConnect/xDisconnect methods.
+# vtab1-3.*: Table scans and WHERE clauses.
+# vtab1-4.*: Table scans and ORDER BY clauses.
+# vtab1-5.*: Test queries that include joins. This brings the
+#            sqlite3_index_info.estimatedCost variable into play.
+# vtab1-6.*: Test UPDATE/INSERT/DELETE on vtables.
+# vtab1-7.*: Test sqlite3_last_insert_rowid().
+#
+# This file uses the "echo" module (see src/test8.c). Refer to comments
+# in that file for the special behaviour of the Tcl $echo_module variable.
