This should be probably cross-posted to tex.stackexchange.com. However, since my question is more oriented towards writers who also have a firm grasp of technology, I'm posting it here in hopes of getting a better answer. (I hope the collaboration part won't stir up a hornets' nest, it's merely meant to facilitate discussion.
LaTex provides a really good document preparation system, but the specifics can be a bit stiff for newbies to learn. Similarly, UNIX tools like git, etc. provide a good form of version control for something like a novel (This concept has been already explored in Flashbake - http://bitbucketlabs.net/flashbake/)
I was wondering whether there was a tool that combines both of these with a newbie-accessible frontend, so an author can generate the complete manuscript of his work whenever needed, and rollback if needed as well. Is there such a tool in production; or have people on this board ever thought of making one?
