After a fashion anyway. Rest assured that under the hood though it's all change. Gone is the home grown database access layer and in it's place a shiny new Class::DBI based one. Thanks to this it's all a lot cleaner, more extensible (hence the addition of the journal bit) and approaching a stage where I'd consider releasing it. Maybe if I can work up the enthusiasm to either write an install script or steal chunks of someone else's. First I need to smooth off a few rough edges though.
