# Test organization:
#
# 1.* - Warm-body tests.
#
# 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.
