Start with an empty store

[smiley 0]

On a default install, the desire is an empty store.
I realise I could delete all products etc. in the admin but I seem to remember there is a way to empty the relevant tables using phpmyadmin.
Anyone care to share that?

What we really need to ship with the base osC is an SQL snippet to delete the sample store merchandise in one operation, leaving the rest of the database setup intact, and not disturbing any configuration that might have been touched by the owner. If it's invoked with a PHP file in admin, it could erase the sample images too. If you want to get elaborate, you could install with an empty store, run a PHP file to load images and SQL with a sample store, and when configuration is done, run another PHP file to unload the sample store. Any takers?
