我可以将MySQL数据库与App Engine应用程序一起使用

I know that App Engine has its own datastore. This is great for most cases and fairly easy to used. However, we have a MySQL database that we use for several applications and not all of them are Web based. We want to use App Engine for many reasons, but would like to have the App Engine application access our MySQL database. The documentation I've found doesn't clearly state whether I can do this or not. Has anyone done it or have pointers to documents that show how to do it?I know that App Engine has its own datastore. T
