[Shotwell] How to remove metadata from photo files?

[Thomas Jost]

Hi list,

I've been using Shotwell for several months now and I really like it.
Lightweight and efficient -- just what I like on my computers running
Arch Linux.

When I switched to Shotwell, I enabled the option to write tags and
other metadata inside the photo files. Since then I realized that it's
probably a bad idea when you want to do regular backups. (Right now I'm
using unison to backup and sync the DB and pictures on several
computers, but I'd like to switch to a real VCS like git/git-annex or
boar).

So is there a (simple) way to remove these metadata while leaving the
pictures intact? I'm perfectly fine with long command lines and
shell/Python/Perl scripts, it's just that I don't know where to start
and I'm a little lost with all these EXIF, IPTC and XMP things :)

Thanks!

Best regards,
