+# Test plan:
+#
+#   1.* - Warm-body tests created for specific purposes during development.
+#         Passing these doesn't really prove much.
+#
+#   2.1.* - Test that FTS queries only ever return rows associated with
+#           the requested language.
+#
+#   2.2.* - Same as 2.1.*, after an 'optimize' command.
+#
+#   2.3.* - Same as 2.1.*, after a 'rebuild' command.
+#
+#   3.* - Tests with content= tables. Both where there is a real 
+#         underlying content table and where there is not.
+#
+#   4.* - Test that if one is provided, the tokenizer xLanguage method
+#         is called to configure the tokenizer before tokenizing query
+#         or document text.
+#
+#   5.* - Test the fts4aux table when the associated FTS4 table contains
+#         multiple languages.
