Is said Nat and Larry Ewing, they plan to support RAW files.

Hey guys, do you mind joining my effort ? I currently have a request for a new project at Freedesktop.org, and I'm waiting after that to start have a common work. But if you have any other hosting solution (not sourceforhe please), you're welcome.

BTW, if you want Sigma XF3 files, there are plenty linked from there. I'm currently starting collecting them as well.
