+=========================
+
+1. The testsuite "funcs_1" is mostly intended for additional (compared
+   to the common regression tests stored in mysql-test/t) checks
+   of features (VIEWS, INFORMATION_SCHEMA, STORED PROCEDURES,...)
+   introduced with MySQL 5.0.
+
+2. There were some extensions of this suite when new information_schema
+   views were introduced. But in most cases the tests for these views
+   were stored within the regression testsuite (mysql-test/t).
+
+   INFORMATION_SCHEMA views introduced with MySQL 5.1
+   ==================================================
+   ENGINES       (partially tested here)
+   EVENTS        (partially tested here)
+   FILES
+   GLOBAL_STATUS
+   GLOBAL_VARIABLES
+   PARTITIONS
+   PLUGINS
+   PROCESSLIST   (full tested here)
+   PROFILING
+   REFERENTIAL_CONSTRAINTS
+   SESSION_STATUS
+   SESSION_VARIABLES
+
+3. Some hints for maintainers of this suite:
+   - SHOW TABLES ... LIKE '<pattern>'
+     does a case sensitive comparison between the tablename and
+     the pattern.
+     The names of the tables within the informationschema are in uppercase.
+     So please use something like
+        SHOW TABLES FOR information_schema LIKE 'TABLES'
+     when you intend to get the same non empty result set on OS with and
+     without case sensitive filesystems and default configuration.
+   - The name of the data dictionary is 'information_schema' (lowercase).
+   - Server on OS with filesystem with case sensitive filenames
+     (= The files 'abc' and 'Abc' can coexist.)
+     + default configuration
+     Example of behaviour:
+     DROP DATABASE information_schema;
+     ERROR 42000: Access denied for user ... to database 'information_schema'
+     DROP DATABASE INFORMATION_SCHEMA;
+     ERROR 42000: Access denied for user ... to database 'INFORMATION_SCHEMA'
+   - Try to unify results by
+     --replace_result $engine_type <engine_to_be_tested>
+     if we could expect that the results for storage engine variants of a
+     test differ only in the engine names.
+     This makes future maintenance easier.
+   - Avoid the use of include/show_msg*.inc.
+     They produce "SQL" noise which annoys during server debugging and can be
+     easy replaced by "--echo ...".
