[Matej Mailing]

Hi,

thanks for sending it. I have found out that the
AnimateLayersExtension is already in the extensions directory, but was
unaware of its meaning.

How do I define the layers to animate? Do I have to edit the
AnimateLayersExtension by hand (which I don't want)? Should I add
something at the layer's definition in the mapbook.xml and if so,
what?

Thanks a lot for clarification,
Matej
