"hopefully". If you can get the same procedure to work on another
exporter, such as SVG, I'd be closer to be willing to say "certainly".

To the best of my knowledge, there is nothing like this right now.

If you can have pydia up & running, and if pydia is able to manipulate
layers, I guess you can whack something together that way.

Otherwise, the way I would implement it (note the "would", I don't have
the time to do it now, even if bri^Whired for that) would be a pair of flags:
	--force-layers-off layer1,layer2,layer3,layer4,layer5,layer6
	--force-layers-on layer4,layer5
would leave you layer4 and 5 on, the rest off.

this way you can quickly select what you actually want off and on in a
quick shell script, without the need for dia to define what "animate"
really means (sometimes you'll want a specific layer to be always on,
etc. plus it's not very nice to impose layer names upon the user).

Should be a fairly easy beginner's job.
