#---------------------------------------------------------------------------
# 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.
