LibRaw License

When I want to use libraw in a closed source android app, do I need to actually get you to sign the libraw license copy and sign it with my own signature, or is just mentioning the attribution and the used license enough?

Great work by the way!

You may choose LGPL or CDDL

You may choose LGPL or CDDL license and just use LibRaw in your (closed source) app. Most users (developers) do so. You don't need to notify us about your app.

The LibRaw own licensing is used only for compatibility with LibRaw-pre-0.9 (commercial version).
