Module documentation tabs or child pages?

Hey, so I just agreed to start going through the contribued modules to help out with the documentation. I was wondering if it's possible, like in the downloads section, to have the documentation sectioned off by version number? A few people, I see, complained that the information is out of date.

This, however, raises another issue (please let me know if I'm supposed to post this in another issue / feature request). It seems to me, there would need to be book pages like: 4.6, 4.5, cvs, and older. From what I gather, the change between 4.5 and 4.6 was pretty small, and many of the pages are relevant to both versions. I don't know how anyone would be able to check on that and copy the page to both sections. Plus, when the new 4.7 comes out, all the documentation would have to hang out in the old section and there would be very little documenation in the new 4.7 page. Of course, that's not necessarily a bad thing - at least we would know which info is relevant to our version number.

Which leads me to wonder, who submits those pages anyway?
