I would like to create a nested ncx for epub and an flat ncs for Kindle/mobi (I understand Kindle does not support nested ncx).

Will both these files need to be created manually? Are they output from any converter? Or can I create an ePub and then convert it to a Kindle mobi (using Kindlegen or other converter) or vice-versa and end up with a valid ncx?

I notice in the Kindlegen Sample folder that the ncx is a) nested and b) has class definitions -- although I can't find any css with those definitions in it. Can an ncx utilize css in one version and not in another? If a class can be included, where would the css go?

(Should this thread be posted elsewhere?)

Thanks very much for any help.
