What's coming soon [1 - 3 centuries, what with the day job and all]:

• A Config file or files containing setup info [ which scripts to execute for which drivers at which hook points, symbolic names for DBI DSNs, etc ]
• Postgres driver [ currently (semi)broken ]
• DB2 driver [ depends on whether I can get my hands on a running installation of DB2 ]

Longer Term and 'Maybes':

• Context sensetive help...
• Multiple dispatch [dispatch the same SQL query to multiple DBs simultaneously]
• A shiny GTK interface... have begun work
