The ezsqldumpschema.php script in bin/php can create the dba file for you. Unfortunately it is not yet capable of dumping only a couple of tables instead of the whole db (but there is a feature request for that)

I have been testing the ezsqldumpschema.php script and it works fine but the table engine, charset and comment, are not specified in the generated file... Maybe it isn't possible :( .
