+#
+#   2.* - Querying a content=xxx FTS table.
+#
+#   3.* - Writing to a content=xxx FTS table.
+#
+#   4.* - The "INSERT INTO fts(fts) VALUES('rebuild')" command.
+#
+#   5.* - Check that CREATE TABLE, DROP TABLE and ALTER TABLE correctly
+#         ignore any %_content table when used with the content=xxx option.
+#
+#   6.* - Test the effects of messing with the schema of table xxx after
+#         creating a content=xxx FTS index.
+#   
+#   7.* - Test that if content=xxx is specified and table xxx does not
+#         exist, the FTS table can still be used for INSERT and some
+#         SELECT statements.
+#
+#   8.* - Test that if the content=xxx and prefix options are used together,
+#         the 'rebuild' command still works.
+#
+#   9.* - Test using content=xxx where xxx is a virtual table.
+#
+#   11.* - Test that circular references (e.g. "t1(content=t1)") are
+#          detected.
