sdb is an utility to manage a collection of live shows.
It's main purpose is to provide a gui frontend to view, add and edit shows with some basic report functions. Another goal is to provide a set of export functions mainly to publish your list of tradeable shows on the web.
Currently there's no so called "offical" release of this tool. But you can always download a working version in the download section. Maybe there are some changes within the internal data structure, but you will never loose important data. What you can do with these snapshots is organizing your shows (of course, with some limitations), edit your shows and export them to a format you can publish on the web.
Take a look at the development section to communicate bug reports, feature requests and so on...
