List Database Sizes For All MySQL 4.1 databases

Greetings,

Does anyone have a script that will list database sizes for all MySQL 4.1 databases? I have a script that will do it for MySQL 5.1 but that script does not work for MySQL 4.1.  Here's the script that works from me in MySQL 5.1:

SELECT NOW(), VERSION();

SELECT table_schema,

 SUM(data_length+index_length)/1024/1024 AS total_mb,

 SUM(data_length)/1024/1024 AS data_mb,

 SUM(index_length)/1024/1024 AS index_mb,

 COUNT(*) AS tables,

 CURDATE() AS today

FROM information_schema.tables

GROUP BY table_schema

ORDER BY 2 DESC;

# Set a session variable for the largest schema for later use

SELECT @schema := table_schema,

 SUM(data_length+index_length)/1024/1024 AS total_mb

FROM information_schema.tables

GROUP BY table_schema

ORDER BY 2 DESC

LIMIT 1;

Please HELP!
