Is there a tool that makes the task of editing user privileges easier on a MySQL database? I've got nearly 100 tables to work through for 4 users, each with different per-table grants, which is getting tedious via phpMyAdmin. It'll get a lot more irritating when I make changes to the database structure and user list later on. I also can't see a way to do it in MySQL Workbench.
Are there any permissions management tools that make management of table permissions easier?
Update: For clarification, I need a tool that can manage the per-schema and per-table permissions for a user. I'll be changing permissions later, so it needs to be able to fully manage existing permissions as well as grant new ones. MySQL Workbench allows management of per-schema privileges, but not per-table.
