Document how to pre-load a database in the SQL kernel
AFAIU, it's possible to load a .sql (dump) file, interactively with the File>Open menu, which will load and execute a SQL script. This is handy to populate a database for users to play with.
However this is not documented AFAICS.
Also, I'm not sure this works with the aux argument. This would also deserve some documentation, I think.
Thanks in advance.
