Just swap in the database plugin you need for your database and get rid of the
FrontBase plugin from the classpath.
Rerun the creation of Migration0 from EntityModeler and replace the version
that is in the project. That should get you the tables you need in the format
your database uses.

Watch the screen cast :-) which should be available pretty soon. I am just
making it available for Pascal to post now.
Also read the package overview as Kieran and Amedeo suggested. It explains all
the settings that are used below.

If true, a file with the same name overwrites, if false it adds a value to make
the filename unique

path to root folder for attachments

It will create any folders it needs in the system path. The only caveat is that
it needs to be writeable by the application (in development OR deployment)

Doesn't matter. I think I am using
/Library/WebServer/Documents/ApplicationName/Attachment
If you use the filesystem you'll likely need to make the folder writeable for
your application.
You can also use Amazon S3 or your database. It is all completely configurable.
