> Being able to keep documents in the same version control system as your code is also a useful tool IMHO. I hate it when management insists on keeping documentation in something like Confluence. If checkout an old version of the code I want a matching old version of the documentation from that time. I'm a big fan of this as well; another huge upshot is that you can write the documentation at the same time as the code and bring it along during the code review.
