How to Convert MS Access Database to MySQL

MySQL Workbench (versions 5 and 6) contain a Migration Toolkit to convert external databases to MySQL, but Microsoft Access isn't an option.  However, it used to be an option in the predecessor tool: MySQL GUI Tools.  Fortunately, you can download an archived installer for MySQL GUI Tools here:

With that, if you install MySQL GUI Tools (and install a 32-bit version of the Java JRE 6), if you start the MySQL Migration Toolkit, there is an option to convert from an Microsoft Access database.  I chose all of the default settings (except I asked for .sql scripts to be saved), and it converted fine.
