Book export and update

Hello,
I have a quick question about exporting and importing books: I was thinking to write my Drupal web-app's documentation directly in a book on the site, then include all the code/views/configuration AND this book in a feature and deploy it on the various sites.

If I update this book on the "master" site, and include it in the next version of the feature, when deploying everything the old book content will be updated with the new one, or Features can't track modifications to a book and it will create another one?

Thanks!
