Script to export Photos from Digikam to NGG

This program exports pictures from your
DigiKam (http://www.digikam.org/) database to a
NGG (http://alexrabe.boelinger.com/category/nextgengallery/) database.
It is at the moment highly experimental and in a works-for-me-right-now
state.
Be really really careful if trying to use it, it will
- determine which photos are tagged "public"
- upload them to a dir, kill everything in the target dir not tagged public
- rewrite the remote database
- automatically create thumbnails along the way
I don't know much about databases, so this code is quite inefficient. It
doesn't pose a big problem for my ~5k local, 100 remote photos, though
Once again, it *will* erase the remote directory, and possibly more.
NO WARRANTY!
see http://andreas.goelzer.de/synchronizing-digikam-and-ngg for updates.
